Use guidance

From selection
to application.

Application

The mixture is poured onto the surface and is then applied in a minimum of 2 layers with a brush, scraper or roller until the whole surface is covered. The second layer should be applied 12 at minimum and 24 hours at maximum after the application of the first player. The resting time between the layers should not exceed 48 hours. The tools used during the application should be cleaned within 2 hours after the application. Also applicable as one thick layer. Should be applied with a usage of 1.5 – 2 l/m².
