Base requirements and coating conditions
The concrete must have a minimum strength class of C25/30 and wear resistance class 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. Moisture must not rise into the structure due to capillary action. Good ventilation must be ensured during application. Odours generated during the work can be reduced by using negative pressure ventilation.
New concrete floor
Cement laitance and any uncured cement must be removed by surface grinding or shot blasting. All loose and adhesion-reducing material must be removed, and cement dust must be carefully vacuumed off.
Old concrete floor
Cement laitance and deteriorated concrete must be removed by grinding or shot blasting. 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.
Metal and ceramic tile
Metal substrates must be blast-cleaned to a sufficient level. Ceramic tiles must be firmly bonded to the substrate. The tile surface must be roughened by grinding the glaze. An overfill/levelling layer with acrylic mortar is recommended on tiled substrates to prevent tile joints from showing through the finished coating.
Patching
Small holes and cracks are cleaned and filled with an acrylic putty made of acrylic binder and thickening fiber (Sylothix). Larger and more extensive overfills, levelling, and slope formation can be done using a filling/levelling mortar made of Nanten Acrylic 20N binder and filler sand.
Mixing
Pre-mix the desired amount of Nanten Acrylic Primer 107. Assess the effect of temperature on the required amount of hardener and add the hardener to the mixing container. Continue mixing for approximately two minutes.
Mixing ratio
Nanten Acrylic Hardener is used as the hardener, and the required amount depends on the working temperature.
1 dl of hardener = 64 g
+30°C 1 wt-%
+20°C 2 wt-%
+10°C 4 wt-%
+3°C 6 wt-%
Application instructions
Applied with a brush, roller, or rubber squeegee.
