Base requirements and coating conditions

The concrete strength class must be at least C25/30 with a wear resistance class of 3. The relative humidity of the concrete must be below 98%, and the surface temperature must be at least +3°C above the dew point. During application and curing, the temperature of the air, surface, and coating must remain above +10°C, and the relative humidity (RH) of the air must be below 80%. Always ensure the suitability of the paint for the intended substrate.

New concrete floor

Cement laitance and any uncured cement must be removed by surface grinding. All loose and adhesion-reducing material must be removed, and the surface must be thoroughly vacuumed to remove all cement dust.

Old concrete floor

Cement laitance and deteriorated concrete must be removed by grinding. All loose and adhesion-reducing material must be removed, and the surface must be thoroughly vacuumed. Dirty floors should be washed and rinsed with a synthetic detergent before any further surface preparation. Any existing old paint film must be completely removed from the substrate.

Priming 

For priming, add warm water (approx. +30°C) at 10–20% as the final component after mixing Parts A and B. Continue mixing for approximately 2 minutes. The water should be added in a continuous stream while mixing. The primer must seal all pores in the concrete to form a dense and continuous film on the surface.

Patching

Small holes and cracks are cleaned and filled with an epoxy putty made of for example, HM Epoxy and fine filler sand.

Mixing

Pre-mix Part A and Part B of EP W2 Epoxy in their own containers. Estimate the required amount of mixture based on the size of the area to be treated and the working time of the product. Combine the components in the correct volume ratio and mix thoroughly with a low-speed mechanical mixer for approximately two minutes, avoiding air entrapment in the mixture. For priming, add water as the final component after mixing and continue mixing for approximately 2 minutes.

Coverage

Coverage is approximately 4–5 m² per litre / two coats, depending on the porosity of the substrate.

Application instructions

If the priming is older than two days, the surface must be roughened by sanding and all sanding dust must be removed. The coating is applied using undiluted EP W2. Pre-mix Part A and Part B of EP W2 in their own containers. Estimate the required amount of mixture based on the size of the area to be treated and the working time of the product. Combine the components in the correct volume ratio and mix thoroughly with a low-speed mechanical mixer for approximately three minutes, avoiding air entrapment in the mixture. Pour the mixture onto the floor in a puddle or continuous bead, then spread with a roller or rubber squeegee followed by back-rolling.

Insufficient mixing may cause uneven curing or color variation in the finished surface. Do not scrape any remaining material from the sides of the container onto the floor.
