Step 1: Surface Preparation

Proper preparation is the most important step in achieving a flawless finish.

 

✅ Clean and Dry the Surface Thoroughly

Start by sweeping and vacuuming the entire surface to remove loose dust and debris. Use a degreaser or detergent if there are oil stains or any form of contamination. It’s essential that the surface is:

 

 Free from oil, grease, dust, and loose particles

 Completely dry before application

✅ Repair Any Cracks or Holes

For the best finish, patch up holes or cracks using a concrete repair mortar or filler. The final appearance of the floor will reflect the quality of your preparation—so take the time to ensure the surface is smooth and solid.

 

✅ Etch, Grind, or Scarify for Adhesion

For best results, especially on power-floated or sealed concrete, mechanically prepare the surface using a floor grinder or scarifier. This helps the epoxy coating bond effectively and reduces the risk of delamination. Floor grinders are widely available for hire at most tool rental stores.

 

Recommended Surface Temperature:

Between 5°C and 25°C.

Too cold and the epoxy may not cure properly. Too warm and it could cure too quickly to work with.

 

⚙️ Step 2: Product Preparation

Everest Trade HB Epoxy floor paint is a two-part system, consisting of a resin base (Part A) and an activator (Part B). Once mixed, you’ll have a pot life of roughly 30 minutes, so only mix what you can apply in that window.

 

✅ Get Your Mixing Station Ready

Prepare a clean, disposable area with plastic sheeting or cardboard to catch any spills.

 

✅ Tools You’ll Need:

 Electric drill with paddle mixer

 ProDec 24" Drill Fit Stirrer (specially designed for epoxy mixing)

 Paint scuttle or tray

 Heavy-duty roller application kit

 Paintbrushes for edging

 Masking tape (optional)

✅ Mixing Instructions:

Stir Part A (resin) on its own for 1–2 minutes.

Add Part B (activator) and continue mixing thoroughly for another 1–2 minutes.

Ensure there are no streaks or unmixed material—consistency is key.

⚠️ Don’t delay—once mixed, you have 30 minutes before the product begins to cure.

 

�� Step 3: Applying the Epoxy Floor Paint

With your surface prepared and your first unit mixed, it’s time to get painting.

 

✅ Cut In Around Edges First

Use a brush to paint along the edges, corners, and hard-to-reach areas first. This allows you to roll freely without needing to pause later for detailing.

 

✅ Work in Measured Sections

Mark out your floor in sections based on your coverage rate. A 5kg unit will cover approximately 17–20m² depending on surface porosity. This helps ensure even thickness and prevents running out mid-way.

 

✅ Begin Rolling

Pour the mixed epoxy into a scuttle or tray and apply with a heavy-duty roller. Roll in thin, even layers using an M or W motion, ensuring no puddling.

 

⚠️ Expect the First Coat to Look Patchy

This is completely normal on bare concrete or porous floors. The second coat will even everything out and provide the full gloss finish.

 

✅ Remove Masking Tape

If using masking tape, remove it carefully before the paint begins to cure to avoid tearing or pulling at the surface.

 

⏱️ Step 4: Curing and Second Coat

✅ Allow the First Coat to Cure

At 20°C, allow the paint to cure for at least 12 hours. The surface should be touch dry before proceeding.

 

✅ Apply the Second Coat

Mix a new batch using the same method and apply the second coat within 24 hours of the first. This coat will provide:

 

 Full colour depth

 High-gloss finish

 Enhanced chemical and abrasion resistance

Let the second coat cure for 12–16 hours before walking on the surface. For vehicle traffic, wait 48 hours. Avoid cleaning or exposing the floor to water for 7 days, after which full chemical resistance will be achieved.

 

�� Step 5: Aftercare and Maintenance

Now that your floor is finished, maintenance is simple:

 Clean with mild detergents (no acidic or alkaline cleaners)

 Avoid dragging sharp objects across the surface

 Recoat only when surface dulls or wears—typically every 3–5 years
