Key Takeaways
- Surface preparation is crucial – accounting for 80% of installation success, requiring thorough cleaning, crack repair, mechanical grinding, and moisture testing before any epoxy application begins
- Precise mixing ratios and timing are essential – most epoxy systems use 2:1 to 4:1 ratios by volume, with working times of 20-30 minutes at room temperature and coverage rates of 700-800 grams per square metre
- Environmental conditions must be controlled – maintain temperatures between 15-25°C and humidity below 60% throughout application and curing to prevent adhesion failures and surface defects
- Apply in manageable sections with proper technique – work in 10-15 square metre sections, starting from the furthest corner, using systematic cutting-in and rolling methods to ensure uniform coverage
- Full curing takes 7-14 days minimum – whilst light foot traffic is possible after 24 hours, vehicle traffic requires 7 days and complete chemical resistance develops after 14 days of proper curing
- Long-term maintenance preserves the investment – daily dust mopping, weekly pH-neutral cleaning, and annual inspections can deliver 15-20 years of service life from residential installations
Picture transforming your tired concrete floor into a gleaming, mirror-like surface that’s tougher than nails and built to last decades. That’s exactly what you’ll achieve when you master the art of pouring epoxy flooring – a process that’s both surprisingly technical and incredibly rewarding.
You might think “self-levelling” means you can simply pour and walk away, but the reality requires precision, proper preparation, and the right technique. Professional-grade epoxy flooring applications typically use 700-800 grams per square metre and demand meticulous surface preparation, from mechanical grinding to moisture assessment.
The five-step process we’ll explore transforms liquid resin and hardener into an industrial-strength surface that resists heavy mechanical loads whilst maintaining high chemical resistance. Whether you’re tackling a garage, workshop, or commercial space, understanding these fundamentals will help you achieve that coveted high-gloss finish that screams quality from every angle.
Materials and Tools Required
Successful epoxy floor installation depends on having the correct materials and professional-grade tools before you begin. Gathering everything in advance prevents delays during the critical mixing and application phases when timing becomes essential.
Essential Materials
Epoxy floor coating kit forms the foundation of your project. Choose a high-quality two-component system that includes both resin and hardener components. Most residential applications require approximately 700-800 grams per square metre of coverage.
Concrete patching compound repairs any surface imperfections. Fast-setting epoxy repair mortar works best for filling cracks and chips in the substrate before coating application.
Concrete degreaser removes oil and chemical contamination. This cleaning solution ensures proper adhesion between the epoxy coating and concrete surface.
Muriatic acid etches the concrete surface. Acid etching creates the microscopic texture needed for optimal epoxy bonding.
Painters tape protects adjacent surfaces such as walls and fixtures during application.
Plastic sheeting covers furniture and equipment that cannot be removed from the workspace.
Material | Quantity per 50m² | Purpose |
---|---|---|
Epoxy coating kit | 35-40kg | Primary floor coating |
Concrete degreaser | 2-3 litres | Surface preparation |
Patching compound | 1-2kg | Crack repair |
Muriatic acid | 1 litre | Surface etching |
Required Tools and Equipment
Application tools determine the quality of your finished surface. Professional-grade equipment produces smooth and consistent results across the entire floor area.
3-inch paintbrush cuts in edges and corners where rollers cannot reach effectively. Purchase one brush for each coat you plan to apply.
High-quality 12-inch rollers apply the main coating. Medium-knit roller sleeves work best with epoxy materials. Larger rollers speed up application on extensive garage floors.
Roller frame and extension pole reduce physical strain during application. A 3-metre extension pole allows you to work standing upright.
Large roller tray holds sufficient material for continuous application without frequent refilling.
Variable speed drill mixes the two components thoroughly. Attach an 80mm x 430mm mixing paddle for optimal blending.
Floor squeegee spreads the epoxy evenly across the surface and removes air bubbles.
Spiked shoes allow you to walk on wet epoxy without leaving footprints during application.
Power scrubber with attachments prepares the concrete surface through mechanical cleaning action.
Wet-dry shop vacuum removes dust and debris from the prepared surface before coating application.
Latex gloves protect your hands from chemical contact during mixing and application.
Respirator masks filter epoxy vapours and protect your respiratory system during the curing process.
Safety equipment includes work gloves and eye protection for handling chemicals and power tools during surface preparation.
Surface Preparation

Surface preparation determines the success of your epoxy floor installation. Proper preparation accounts for 80% of a successful epoxy application, making this phase critical for achieving professional results.
Cleaning the Concrete Floor
Cleaning the concrete floor removes contaminants that prevent proper epoxy adhesion. Remove all furniture, equipment, and stored items from the area to access the entire surface. Sweep the floor thoroughly using a stiff-bristled broom to eliminate loose debris and dust particles.
Vacuum the surface with a wet-dry shop vacuum to capture fine dust particles that sweeping missed. Focus on corners, edges, and expansion joints where debris commonly accumulates.
Apply a concrete degreaser to areas with oil stains, grease spots, or chemical residues. Scrub contaminated areas with a stiff brush and allow the degreaser to work for 15-20 minutes before rinsing. Use a mechanical power scrubber for large areas or stubborn stains, as this method proves more efficient than manual scrubbing.
Rinse the floor with clean water and remove all cleaning residue. Allow the surface to dry completely before proceeding to the next step. The concrete must be bone dry before epoxy application to prevent adhesion failures and coating defects.
Repairing Cracks and Defects
Repairing cracks and defects creates a smooth foundation for your epoxy coating. Inspect the entire floor surface for cracks, chips, holes, gouges, and other damage that could affect the final appearance.
Fill minor cracks and chips using a concrete patching compound or fast-setting epoxy repair mortar. Work the material into cracks using a putty knife or trowel, ensuring complete coverage. Overfill slightly to account for settling and shrinkage during curing.
For larger holes and gouges, use an epoxy paste mixture combining epoxy resin with filler powder. Apply the mixture with a spatula or broad knife, smoothing the surface to match the surrounding concrete level. Remove excess material while still workable to avoid creating high spots.
Allow all repairs to cure according to manufacturer specifications before proceeding. Typical curing times range from 2-24 hours depending on the repair product and environmental conditions. Sand any high spots flush with the surrounding surface once cured.
Etching for Better Adhesion
Etching for better adhesion creates a rough surface profile that enhances epoxy bonding. Mechanical preparation proves most effective for achieving consistent results across the entire floor surface.
Use a floor grinder or scarifier to mechanically prepare the concrete surface, particularly on power-floated or sealed concrete. This process removes the top layer of cement paste and exposes the aggregate beneath, creating the ideal surface profile for epoxy adhesion.
Rent a floor grinder from equipment rental companies, as these tools are widely available and cost-effective for single-use applications. Work systematically across the floor in overlapping passes to ensure uniform preparation.
Pay special attention to floor edges where walls meet the concrete. Use a handheld grinder to prepare these areas properly, as larger equipment cannot access tight spaces. Edges represent the most common failure points for epoxy installations due to inadequate preparation.
Alternative preparation methods include acid etching with muriatic acid or shot-blasting for industrial applications. These methods require additional safety precautions and proper ventilation.
Testing for Moisture
Testing for moisture prevents costly adhesion failures and coating defects. Conduct moisture tests even on seemingly dry concrete, as hidden moisture can cause significant problems after installation.
Perform a simple plastic sheet test by taping plastic sheets to different areas of the floor and leaving them for 24 hours. Check for condensation or darkening beneath the plastic, which indicates excessive moisture levels.
Use a concrete moisture meter for more accurate measurements. Moisture content above 4% typically requires additional drying time before epoxy application becomes viable.
Test for hydrostatic pressure by applying small amounts of water to the surface and observing absorption rates. Slow absorption or standing water indicates potential moisture issues that require addressing before coating application.
Check environmental conditions during testing, ensuring air temperature stays between 10-30°C and relative humidity remains below 85%. High humidity creates an invisible moisture layer that prevents proper epoxy bonding even when concrete appears dry.
Document all test results and allow additional drying time when moisture levels exceed recommended limits. Proper moisture management prevents up to 90% of epoxy floor failures related to poor adhesion and delamination.
Room Preparation

Room preparation extends beyond surface cleaning to include coverage calculations, area protection, and environmental control for optimal epoxy curing.
Calculating Coverage Requirements
Calculate your floor area by measuring length × width in square metres. Most epoxy systems cover 8-10 m² per litre for standard residential applications, though coverage varies by product thickness and surface porosity.
Check the manufacturer’s datasheet for exact coverage rates. Industrial-grade epoxy typically covers 6-8 m² per litre due to thicker application requirements. Divide your total floor area by the product’s coverage rate to determine required quantities.
Add 10-15% extra material to account for:
- Surface irregularities that absorb more epoxy
- Mixing waste and equipment cleaning
- Touch-ups during application
- Different absorption rates in concrete
For a 40 m² garage floor using epoxy with 8 m² per litre coverage, you require 5 litres plus 0.75 litres buffer, totalling 5.75 litres.
Protecting Surrounding Areas
Mask all adjacent surfaces using painter’s tape on skirting boards, door frames, and wall bases. Apply tape 24-48 hours before epoxy application to ensure proper adhesion without residue.
Cover remaining fixtures with plastic sheeting or drop cloths. Remove lightweight items completely rather than covering them in place. Heavy machinery or built-in cabinets require plastic protection secured with masking tape.
Create barriers at doorways using polypropylene sheets attached with hot melt adhesive. Polypropylene releases easily from cured epoxy, making cleanup straightforward. Seal the floor perimeter with builder’s caulk or silicone sealant to prevent epoxy seepage under walls.
Position drop cloths beyond the work area to catch drips during transport. Even experienced applicators encounter spills when moving between mixing and application areas.
Ensuring Proper Ventilation
Open all windows and doors to create cross-ventilation throughout the workspace. Fresh air circulation accelerates curing and reduces solvent odours during application.
Position fans to maintain consistent airflow without creating dust circulation. Place exhaust fans near windows to draw vapours outside, with intake fans at opposite openings to maintain air movement. Avoid pointing fans directly at wet epoxy surfaces, which can cause premature skinning.
Monitor environmental conditions using a digital thermometer and hygrometer. Maintain room temperature between 18-24°C and relative humidity below 80% throughout the application and curing process. Temperature fluctuations above or below this range can cause:
Temperature Range | Effect on Epoxy |
---|---|
Below 15°C | Slow curing, poor flow |
18-24°C | Optimal curing conditions |
Above 27°C | Rapid cure, reduced working time |
Humidity above 80% can cause surface defects including cloudiness and poor adhesion. Use dehumidifiers in damp conditions or delay application until conditions improve.
Mixing the Epoxy

Mixing epoxy correctly determines the strength and durability of your finished floor. A precise approach to combining resin and hardener creates the chemical reaction that transforms liquid components into a solid protective surface.
Understanding Mixing Ratios
Epoxy mixing ratios vary between manufacturers and product formulations. Most two-component epoxy systems use ratios between 2:1 and 4:1 by volume. Check your product datasheet for the exact ratio before starting any work.
Part A (resin) contains the base polymer while Part B (hardener) contains the curing agent. Incorrect ratios result in floors that remain soft or fail to cure completely. Too much hardener creates excessive heat during curing and can cause bubbling or cracking. Too little hardener leaves sections permanently tacky.
Measure components by volume using graduated containers or scales for weight-based ratios. Eyeball measurements lead to inconsistent results across different mixing batches. Use separate measuring tools for each component to avoid cross-contamination.
Proper Mixing Techniques
Prepare your mixing station before opening any containers. Set up a clean workspace with all tools within easy reach. Use a U-shaped layout with mixing containers on one side and application tools on the other to prevent tripping hazards.
Pre-stir Part A (resin) for 30 seconds before measuring. Resin components can separate during storage. Stirring ensures uniform consistency before combining with the hardener.
Combine measured amounts in a clean mixing container. Pour the hardener into the resin rather than the reverse. This method reduces air incorporation during initial mixing.
Mix components for 2-3 minutes using a spiral mixer attachment on a low-speed drill. Scrape the sides and bottom of the container every 30 seconds to ensure complete blending. Look for a uniform colour with no streaks or swirls.
Work in small batches covering 10-15 square metres per mix. Large batches generate heat and reduce working time. Epoxy begins setting within 15-20 minutes of mixing at room temperature.
Allow mixed epoxy to rest for 30 seconds after mixing. This induction time releases trapped air bubbles that could create surface defects. Skip this step if your product instructions specify immediate application.
Adding Pigments and Decorative Elements
Add pigments during the mixing process for uniform colour distribution. Liquid pigments blend more easily than powder forms. Start with small amounts as epoxy pigments are highly concentrated.
Incorporate decorative flakes after applying the first coat while the epoxy remains wet. Scatter flakes evenly across the surface using a broadcasting motion. Apply approximately 50-100 grams per square metre for partial coverage or 150-200 grams for full coverage.
Mix metallic pigments with the resin component before adding hardener. Metallic effects require specific application techniques including multiple colours and blending tools. Test your desired effect on a small area first.
Add aggregate materials like quartz sand during mixing for enhanced durability. Use 10-20% of the total epoxy weight in aggregate. Stir thoroughly to distribute particles evenly throughout the mixture.
Applying the First Coat

Applying the first coat determines the quality of your entire epoxy floor project. The first coat creates the foundation for adhesion and durability if you follow proper techniques and timing.
Cutting in Around Edges
Cutting in around edges ensures complete coverage in areas where rollers cannot reach effectively. Start by preparing a 3-inch flat brush with epoxy coating to handle detailed work around walls, corners, and fixed objects.
Apply the epoxy coating in thin, even strokes along the perimeter of the room. Maintain a 2-inch border from the wall to allow smooth transitions when rolling the main floor area. Keep the brush at a 45-degree angle to the surface for optimal control and coverage.
Work systematically from left to right to avoid missing sections. Apply light pressure to prevent pooling or excess material buildup at the edges. Check each section for uniform thickness before moving to the next area.
Rolling Technique for Even Coverage
Rolling technique creates uniform epoxy distribution across the floor surface. Select a lint-free roller with a 9-inch sleeve and appropriate nap length for your desired finish texture.
Pour the mixed epoxy in ribbons across the prepared floor surface. Use a notched squeegee to spread the material evenly before rolling. The squeegee technique ensures proper mil thickness and eliminates excess material.
Back-roll the entire area immediately after spreading with the squeegee. Roll in overlapping patterns to eliminate air bubbles and create consistent coverage. Maintain a wet edge throughout the process to prevent visible seams in the finished surface.
Apply consistent pressure during rolling to avoid creating texture variations. Roll at a steady pace to prevent the epoxy from setting before you complete the coverage. Use isopropyl alcohol to eliminate micro-bubbles that appear during application.
Working in Manageable Sections
Working in manageable sections maintains control over the epoxy application process. Divide your floor into 10-square-metre sections to ensure proper coverage before the material begins to set.
Start from the farthest corner and work towards the exit to avoid walking on wet epoxy. Complete each section fully before moving to the adjacent area. This approach prevents lap marks and ensures uniform appearance across the entire floor.
Monitor the pot life of your mixed epoxy throughout the application. Most epoxy formulations provide 20-30 minutes of working time depending on temperature and humidity conditions. Plan your section sizes accordingly to complete each area within this timeframe.
Maintain optimal environmental conditions during application. Keep the temperature between 15-25°C and relative humidity below 75% for proper curing. These conditions ensure 700-800 grams per square metre coverage rates achieve maximum adhesion and durability.
Curing and Second Coat Application

Timing becomes critical once you complete the first epoxy coat application. The curing process determines both adhesion strength and overall floor performance.
First Coat Curing Time
Allow 16-25 hours for the first epoxy coat to cure completely before applying subsequent layers. Temperature affects curing speed significantly – cold conditions below 10°C extend curing time while temperatures above 30°C accelerate the process too rapidly.
Monitor humidity levels during the curing period as excessive moisture creates bonding failures between the concrete and epoxy. Maintain humidity below 85% for optimal results.
Environmental Factor | Optimal Range | Impact on Curing |
---|---|---|
Temperature | 10-30°C | Controls cure speed |
Humidity | Below 85% | Prevents bond failure |
Ventilation | Good airflow | Removes moisture |
Test cure completion by pressing your fingernail into an inconspicuous area. Properly cured epoxy resists indentation and feels firm to touch.
Preparing for the Second Coat
Examine the cured first coat for surface defects including bubbles, craters, or uneven areas before proceeding. Sand down high spots using 120-grit sandpaper and fill low areas with additional epoxy mixed with aggregate.
Remove all dust and debris using a tack cloth or lint-free rag. Clean surfaces ensure proper adhesion between coat layers.
Check pot life specifications on your epoxy packaging – most products provide 40-45 minutes working time at room temperature. Plan your application sequence to complete coverage within this timeframe.
Calculate coverage requirements for the second coat using approximately 700-800 grams per square metre. Mix only the amount you can apply within the pot life window.
Applying the Final Layer
Apply the second coat perpendicular to the first using the same roller technique. Start at the furthest corner from your exit point and work systematically across the floor surface.
Maintain a wet edge by overlapping each roller pass by 10-15cm to prevent visible lap marks in the finished surface. Roll each section twice – once to distribute the epoxy and again to smooth the texture.
Use a floor squeegee immediately after rolling to eliminate any roller marks and achieve uniform thickness. Work the squeegee in straight lines with consistent pressure.
Monitor environmental conditions throughout application. Temperatures between 15-25°C provide optimal working conditions for achieving maximum gloss and durability.
Allow 12-16 hours before foot traffic on the completed second coat. Vehicle traffic requires 48 hours minimum curing time. Full chemical resistance develops after 7 days of cure time.
Apply decorative colour chips during the wet stage if desired. Broadcast chips by hand in overlapping throws to achieve uniform distribution across the surface.
Adding Non-Slip Properties

Epoxy floors can become dangerously slippery when wet, making anti-slip additives essential for safety-critical areas. High-traffic environments like garages, workshops, and commercial spaces require proper grip to prevent accidents.
When to Add Anti-Slip Additives
Add anti-slip additives during the first coat application for optimal performance and durability. Heavy-use garages and workshops benefit most from this safety enhancement, as spillages and wet conditions create hazardous walking surfaces without proper grip.
Commercial environments with high foot traffic demand anti-slip properties to protect staff and visitors. Introduce additives before the final coat cures completely to ensure proper integration into the epoxy matrix. Wet epoxy accepts additives more effectively than partially cured surfaces.
Temperature affects additive distribution, with ideal conditions between 15-25°C producing the most uniform results. Apply additives when relative humidity stays below 85% to prevent moisture interference with the curing process.
Environment Type | Additive Timing | Safety Priority |
---|---|---|
Garage floors | First coat | High |
Workshop areas | First coat | High |
Commercial spaces | First coat | Critical |
Kitchen floors | Final coat | Medium |
Application Methods
Mix anti-slip additives directly into the epoxy after combining the resin and hardener components. Quartz aggregate provides the most effective slip resistance for heavy-duty applications. Blend for 60 seconds minimum to achieve even distribution throughout the mixture.
Broadcast method involves sprinkling additives over wet epoxy surfaces using controlled, sweeping motions. Maintain consistent coverage by working in 2-metre sections to prevent overlap areas. Apply 50-100 grams per square metre depending on the desired slip resistance level.
Seal-in technique requires a second coat over broadcast additives to lock them permanently into the surface. Wait 16-24 hours between the additive application and sealing coat to ensure proper adhesion. Roll the sealing coat perpendicular to the broadcast direction for complete coverage.
Mixing during application prevents settling and maintains uniform distribution. Stir every 5 minutes during the application process to keep additives suspended in the epoxy. Use figure-8 mixing patterns to prevent air bubbles while maintaining additive distribution.
Maximum slip resistance requires additives in both the base coat and topcoat applications. Apply 75% of additives to the first coat and 25% to the final coat for optimal grip without compromising surface smoothness. Test grip levels before full curing to adjust coverage if needed.
Curing and Aftercare

Your epoxy floor application marks the beginning of a critical curing period that determines the final performance and longevity of your investment. Proper curing and maintenance protocols ensure your floor reaches its full strength potential and maintains its appearance for decades.
Full Curing Timeline
Initial setting occurs within 24 hours under optimal conditions between 18-24°C with relative humidity below 50%. Your floor becomes touch-dry and supports light foot traffic during this phase, though the epoxy continues hardening beneath the surface.
Complete curing takes 7-14 days for most residential epoxy systems, with industrial-grade formulations requiring up to 21 days. Temperature significantly affects this timeline – cooler conditions extend curing by 2-3 days per 5°C drop below optimal range, whilst excessive heat above 30°C can compromise adhesion strength.
Curing Stage | Timeline | Traffic Allowance |
---|---|---|
Touch dry | 8-12 hours | None |
Light foot traffic | 24 hours | Socks only |
Normal walking | 48-72 hours | Soft shoes |
Vehicle traffic | 7 days minimum | Cars, light trucks |
Full chemical resistance | 14 days | All chemicals |
Monitor surface temperature rather than air temperature during curing. Surface temperatures between 15-25°C provide optimal curing conditions, whilst concrete temperatures below 10°C halt the chemical reaction entirely.
Initial Care Instructions
Avoid all foot traffic for the first 24 hours to prevent permanent impressions in the soft epoxy surface. Even light pressure from pet paws or dropped tools creates lasting marks during early cure stages.
Clean spills immediately using warm water and mild detergent during the first 48 hours. Harsh chemicals including ammonia-based cleaners, bleach, or citrus-based products can permanently damage the uncured surface chemistry.
Maintain consistent temperature and humidity throughout the initial 72-hour period. Sudden temperature drops cause surface condensation that creates white hazing, whilst rapid heating generates stress cracks. Use space heaters or dehumidifiers to maintain 18-24°C and 40-60% humidity.
Protect against dust and debris by sealing the room with plastic sheeting over doorways. Airborne particles embed permanently in soft epoxy, creating surface defects that require complete refinishing to correct.
Restrict cleaning to gentle sweeping after 48 hours. Mopping introduces excess moisture that interferes with ongoing cure reactions and can cause delamination at floor edges.
Long-Term Maintenance
Daily maintenance requires only dust mopping or dry sweeping to remove abrasive particles that cause microscopic scratches over time. Commercial microfibre dust mops capture fine particles more effectively than traditional brooms.
Weekly cleaning involves damp mopping with pH-neutral cleaners diluted according to manufacturer specifications. Avoid soap-based products that leave residue films, reducing the natural gloss and creating slip hazards when wet.
Monthly deep cleaning uses mechanical scrubbing equipment for high-traffic areas. Auto-scrubbers with soft-bristle brushes remove embedded dirt whilst preserving surface gloss. Rinse thoroughly with clean water and squeegee dry to prevent water spotting.
Annual inspection identifies maintenance requirements before minor issues become major repairs. Check for surface scratches, chemical staining, or adhesion problems around floor edges. Most surface scratches respond to light buffing with fine automotive polishing compounds.
Protective measures extend floor lifespan significantly:
- Place entrance mats extending 3 metres inside doorways
- Use furniture pads under all moveable items
- Apply fresh topcoat every 3-5 years in high-traffic zones
- Maintain indoor humidity between 30-50% year-round
Temperature cycling below 5°C causes epoxy to become brittle and susceptible to cracking. Heated buildings should maintain minimum 10°C during winter months to preserve flexibility and impact resistance.
Proper maintenance delivers 15-20 years of service life from residential installations, with commercial applications achieving 10-15 years under heavy traffic conditions. Your initial investment in quality materials and proper application techniques pays dividends through reduced replacement costs and consistent performance throughout the floor’s operational life.
Common Issues and Troubleshooting
Even experienced applicators encounter challenges during epoxy floor installation. Quick identification and resolution of these issues prevents permanent defects in your finished floor.
Dealing with Air Bubbles
Air bubbles form when trapped gases escape from the concrete surface or become enclosed during mixing and application. Remove bubbles immediately using a blowtorch or heat gun held 12-15 centimetres above the surface.
Pass the flame across bubble-affected areas in smooth sweeping motions. The heat causes bubbles to rise and pop without damaging the epoxy surface. Work systematically across the floor within 20-30 minutes of application whilst the epoxy remains workable.
Prevent bubble formation by maintaining proper mixing speeds below 400 RPM and avoiding excessive agitation. Thick epoxy formulations trap more air than thinner products. Mix components thoroughly but gently to minimise air incorporation.
Temperature affects bubble formation significantly. Concrete temperatures above 25°C increase outgassing from the substrate surface. Cool concrete surfaces to 15-20°C before application using fans or delaying work until cooler periods.
Fixing Uneven Coverage
Uneven epoxy distribution creates visible streaks and bare patches that compromise both appearance and protection. Address coverage issues immediately using a medium-pile roller or notched squeegee.
Work in overlapping passes to redistribute material from thick areas to thin sections. Maintain a wet edge between adjacent areas to prevent visible lap marks. Check coverage using oblique lighting angles that reveal thin spots requiring additional material.
Calculate coverage rates accurately before starting. Most epoxy systems cover 4-6 square metres per litre at recommended thickness. Insufficient material causes patchy coverage whilst excess material creates runs and uneven surfaces.
Apply epoxy in manageable sections of 10-15 square metres. Large areas become difficult to maintain uniform coverage as working time expires. Use multiple applicators for floors exceeding 50 square metres to ensure consistent application before pot life expires.
Temperature and Humidity Problems
Environmental conditions directly affect epoxy curing and final performance. Maintain ambient temperatures between 15-25°C and relative humidity below 60% throughout application and initial curing phases.
Condition | Problem | Solution |
---|---|---|
Below 10°C | Slow cure, poor adhesion | Use heaters to raise temperature |
Above 30°C | Rapid gel, reduced working time | Cool area, work during cooler hours |
High humidity (>70%) | Surface moisture, poor adhesion | Use dehumidifiers, improve ventilation |
Direct sunlight | Uneven heating, surface defects | Block sunlight, apply in shade |
Cold temperatures extend working time but delay curing significantly. Epoxy applied below 10°C may never achieve full hardness and remains permanently soft. Warm the substrate and ambient air using electric heaters placed 3-4 metres from work areas.
Hot conditions reduce pot life dramatically. Mixed epoxy that normally provides 45 minutes working time may gel within 15-20 minutes at 35°C. Work during early morning or evening hours when temperatures moderate naturally.
High humidity creates microscopic moisture layers on concrete surfaces that prevent proper adhesion. Humidity above 70% causes epoxy blushing – a white, cloudy appearance that indicates curing problems. Install dehumidifiers and increase ventilation to reduce moisture levels before application.
Monitor conditions using accurate digital thermometers and hygrometers placed at floor level. Environmental conditions at 2 metres height differ significantly from floor-level measurements where epoxy application occurs.
