| Metallic | 1.5-2.0 | 48-72 | Medium |
Preparing Your Floor for Epoxy Application
Proper floor preparation creates the foundation for a successful epoxy coating installation. The concrete surface requires specific preparation steps to ensure maximum adhesion and longevity of the epoxy coating.
Surface Cleaning Requirements
A clean concrete surface enables optimal epoxy adhesion. Here’s what the cleaning process involves for epoxy:
- Remove existing coatings using a floor grinder or chemical stripper
- Sweep away loose debris with a stiff-bristled brush
- Degrease oil-stained areas with a commercial degreaser
- Clean the entire surface with TSP (trisodium phosphate) solution
- Rinse thoroughly with clean water 3-4 times
- Allow 24 hours for complete drying at 20°C
Equipment needed for cleaning:
- Floor scrubber or power washer
- Industrial vacuum
- Microfibre mops
- Chemical-resistant gloves
- Safety goggles
- Dust masks
Moisture Testing and Repairs
Moisture testing prevents coating failure from water vapour transmission. Essential moisture checks include:
Testing Methods:
- Plastic sheet test: Tape 1m² plastic sheet for 24 hours
- Calcium chloride test: Measures moisture emission rate
- Electronic moisture meter: Provides instant readings
Acceptable Moisture Levels:
| Test Type | Maximum Reading |
|---|---|
| Plastic Sheet | No condensation |
| Calcium Chloride | 3 lbs/1,000 ft²/24 hrs |
| Moisture Meter | 4% moisture content |
- Fill cracks wider than 3mm with epoxy filler
- Patch spalled areas with concrete repair mortar
- Level uneven spots using self-levelling compound
- Sand rough patches until smooth
- Address active water leaks with hydraulic cement
How to Apply DIY Epoxy Floor Coating
Applying epoxy floor coating requires precise mixing ratios and systematic application techniques to achieve a professional finish. The process involves carefully combining the epoxy components followed by methodical application using specific tools and methods.
Mixing the Epoxy Components
Epoxy mixing demands exact measurements to ensure proper chemical reaction and curing. Here’s the essential mixing process:
- Measure components at room temperature (18-24°C) for optimal results
- Combine Part A (resin) and Part B (hardener) at the manufacturer’s specified ratio
- Mix thoroughly for 3-5 minutes using a paddle mixer at 300-400 RPM
- Scrape the sides and bottom of the mixing container every 60 seconds
- Pour the mixed epoxy into a new container and mix for an additional 2 minutes
| Component Ratios | Mixing Time | Working Time |
|---|---|---|
| 2:1 (Standard) | 3-5 minutes | 30 minutes |
| 1:1 (Quick-Set) | 2-3 minutes | 20 minutes |
Application Techniques and Tools
The application process requires specific tools and techniques for consistent coverage:
- 45cm epoxy roller with 10mm nap
- Extension pole for the roller
- Spike shoes for walking on wet epoxy
- Trim brush for edges
- Notched squeegee
- Paint tray with liner
- Cut in edges using a trim brush
- Pour mixed epoxy in 30cm wide ribbons across the floor
- Spread material using a notched squeegee at 45° angle
- Back-roll with epoxy roller in overlapping passes
- Apply decorative chips while coating remains wet
- Maintain a wet edge throughout application
| Coverage Rates | Thickness | Cure Time |
|---|---|---|
| Base Coat | 250µm | 12 hours |
| Top Coat | 150µm | 24 hours |
Common Mistakes to Avoid
Successful epoxy floor installation requires attention to detail and proper technique to achieve professional results. Understanding these common pitfalls helps create a durable, attractive finish.
Temperature and Humidity Concerns
Epoxy floor coatings require specific environmental conditions for proper curing. Applying epoxy in temperatures below 10°C or above 30°C leads to improper curing and adhesion failures. High humidity levels above 85% prevent proper chemical reactions, causing cloudy finishes or surface defects. Monitor both room and floor surface temperatures 24 hours before application, during installation and throughout the curing period.
Coverage and Thickness Issues
Incorrect coverage rates result in uneven protection and premature wear. Applying epoxy too thin (less than 0.25mm) creates weak spots prone to peeling, while excessive thickness (over 0.5mm) causes bubbling and extended cure times. Calculate the exact square metres of your floor space and divide by the kit coverage specifications to determine proper material quantities. Use a wet film thickness gauge during application to maintain consistent coverage of 0.3mm-0.4mm per coat.
Key coverage mistakes include:
- Stretching material too far across large areas
- Creating puddles in low spots
- Missing spots near edges or corners
- Applying uneven coat thicknesses
- Using incorrect roller nap sizes
| Kit Size | Floor Area | Thickness | Cure Time |
|---|---|---|---|
| 3L Kit | 15m² | 0.3mm | 24 hours |
| 5L Kit | 25m² | 0.3mm | 24 hours |
| 10L Kit | 50m² | 0.3mm | 24 hours |

Frequently Asked Questions
How long does DIY epoxy flooring last?
A properly installed and maintained DIY epoxy floor can last 10-20 years. Its longevity depends on factors like traffic levels, maintenance routine, and initial installation quality. Regular cleaning and avoiding harsh chemicals will help maximise its lifespan.
What temperature is ideal for applying epoxy floor coating?
The ideal temperature range for epoxy floor application is between 15-25°C. The concrete surface and air temperature should be within this range, with relative humidity below 80%. Temperatures outside this range can affect curing time and final results.
Can I apply epoxy flooring over existing paint or coatings?
No, existing coatings must be completely removed before applying epoxy. The concrete surface needs to be bare, clean, and properly etched to ensure proper adhesion. Using a concrete grinder or shot blaster is recommended for removing old coatings.
Is moisture testing necessary before applying epoxy?
Yes, moisture testing is crucial. Excessive moisture can cause epoxy coating failure. Use a concrete moisture meter or perform a simple plastic sheet test. The moisture content should be below 4% for successful application.
What tools are needed for DIY epoxy floor installation?
Essential tools include a mixer drill, epoxy roller, spike shoes, trim brush, squeegee, moisture meter, surface preparation equipment, and safety gear (gloves, goggles, respirator). Most DIY kits include basic application tools.
