System Build-Up

	Description	Material	Consumption
	Substrate	Concrete / cementitious screed
1	Primer	KÖSTER CT 215 Universal Floor diluted 10 to 25 % with water. The amount of water depends on the substrate porosity.	0.25 kg/m² per layer (approx. 0.20 resin + 0.05 water)
2	Topcoat	KÖSTER CT 215 Universal Floor. Matt finish and good cleanability	0.25 kg/m²

Comments

Consumption values are indicative and may vary depending on substrate roughness, temperature and porosity, as well as application-related losses. A typical variation of 20% should be considered.
Depending on substrate conditions (e.g. porosity, roughness), a second primer coat and/or a scratch coat may be required.
Depending on the selected topcoat color (e.g. light or bright colors) and the contrast with the underlying layers, an additional topcoat may be required.
The use of anti-slip particles may reduce gloss and modify the surface texture and appearance.
