0.5-0.6kg/m² / treatment time. 1-2 treatment times depending on the desired surface structure. Spreading rate depends on the smoothness of the surface and the number of layers.

The relative humidity of the concrete should be less than 97%. During varnishing and drying, the air, the base and the lacquer must be above +5ºC and the relative air humidity less than 80%.

New concrete: Remove laitance by power grinding, vacuum grit blasting or hydrochloric acid etching. Choose the method best suited for the premises. After grinding remove dust carefully with a vacuum cleaner. Hydrochloric acid etching is carried out with diluted hydrochloric acid (1 part concentrated hydrochloric acid, 4 parts water). Rinse with plenty of water. Dry the floor. Old concrete floor: Remove old, flaky paint film by diamond grinding, milling or sandblasting. Choose the method best suited for the premises. Clean the cavities and potholes in the floor up to healthy, clean concrete. Open cracks, eg with an angle grinder. Remove loose material and dust.

First coat:

The surface varnishing is performed after the coating has hardened. If the pulping is done by sanding method, all loose sand must be removed before the top varnish. Pour the lacquer mixture on the floor in a line and smooth the surface with a roller or brush, depending on the size and design of the floor. Note proper amount of hardener. Using too much hardener can cause yellowing and deterioration of lacquer properties. The film thickness of the surface layer must be 0.4 - 0.8mm. Too thick a layer can also cause yellowing.

Acetone (thinner 006 1500).
