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 +15°C, and the relative humidity of the air must be below 80%. Always ensure the suitability of the coating 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.

Patching

Small holes and cracks must be cleaned and filled with an epoxy filler prepared from Nanten HM Bio Epoxy and fine filler sand. Larger overfills/levelling can be done with a cement-based screed that has sufficient adhesion (>1.5 MPa) and strength (>25 MPa).

Mixing

Pre-mix the components to a uniform consistency in their own containers. Combine components A and B in the correct ratio and mix thoroughly with a low-speed mixer for approx. 2–3 minutes. The product must not be diluted.

Mixing ratio

Part A: 6 parts by volume
Part B: 1 part by volume
Densities: Part A approx. 1.2–1.3 kg/l (paint) and 1.03 kg/l (varnish). Part B approx. 1.15 kg/l

Coverage

Mixture: approx. 0.10–0.14 l/m² per coat. Approx. 50 m² per 7-litre batch.

Application instructions

Nanten PU W2 is applied by cross-rolling to form a uniform and even film on the substrate, using, for example, a microfiber roller. Finish the surface by rolling in one direction only, ensuring that each stroke goes the same way. Consider natural light when choosing the rolling direction. Make sure the wet edge is maintained and that no dry edges form — this helps prevent roller marks in the final surface. Estimate the required amount of mixture based on the size of the area to be treated and the working time of the product.
