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 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.

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 205 binder and filler sand. The maximum thickness of a single application must not exceed 15 mm.

Mixing

Pre-mix the desired amount of Nanten Acrylic 205 binder. 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. Add the required amount of selected color sand to the mixture and continue mixing, avoiding air entrapment in the mass.

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-%

Application instructions

The substrate to be coated must be primed with Nanten Acrylic Primer (101 or 107), and adhesion sand must be broadcast onto the surface. The thoroughly mixed Nanten Acrylic 205 compound (binder + color sands) 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 surface texture can be adjusted by selecting the appropriate grain size of the color sand. Nanten acrylic trowel coatings are sealed with the Nanten Acrylic Sealer 319 or Sealer 304 topcoat, depending on the requirements of the environment.

Nanten Acrylic 205 can also be used for slope corrections and filling. The product is CE-marked and meets the performance requirements of the levelling compound standard EN 13813.

Material usage

At a layer thickness of 3–4 mm, resin consumption is approx. 1.6 kg/m² and filler sand consumption approx. 6 kg/m² (mixing ratio approx. 1:3 by weight and 1:2 by volume). Colored quartz sand is used as filler.

Colour Colorless; the color of the coating is determined by the selected Nanten color sands
