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 not exceed 95%, and the surface temperature must be at least +3°C above the dew point. Good ventilation must be ensured during application, and the relative humidity must be below 80%. 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 concretec 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.

Mixing

Pre-mix the desired amount of Nanten Acrylic 20N-M1 resin. Assess the effect of temperature on the required amount of hardener and add Nanten Acrylic Hardener (BPO) 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 5 wt-%

Coverage

In trowel-applied coatings (3–4 mm), consumption of 20N M1 resin is approx. 1.6 kg/m² and filler sand approx. 6 kg/m².
For priming, consumption of 101-M1 Primer is approx. 0.4–0.5 kg/m².
For top coating, consumption of 319-M1 Sealer is approx. 0.4–0.5 kg/m².
Colored quartz sand is typically used as filler. We recommend using PU-coated filler sand.

Application instructions

The substrate to be coated is primed with Nanten Acrylic 101-M1 Primer. While the primer is still uncured, 0.7–1.2 mm quartz sand is broadcast onto the surface to ensure adhesion of the coating and to improve the workability of the trowel-applied mortar.

The thoroughly mixed Nanten Acrylic 20N-M1 compound (binder + filler sand) is poured onto the floor in a bead and spread with a notched trowel to the desired layer thickness. The surface is immediately finished with a steel trowel. The coating is sealed with Nanten Sealer 319-M1 topcoat, applied in one or two coats depending on the operating environment and the desired surface texture.
