The mixture should be applied on the intended surface with a brush or trowel in a minimum of two layers with dry film thickness of 2 mm. The first layer should be fully dry before the second and the layers are applied perpendicular to the previous layer. Make sure layers are homogenous and smooth. The application should be done in the same direction on any specific layer. After topcoat, the surface should be protected from direct sunlight, air circulation and frost for 3 days. The substrate should be wetted and kept damp if needed.
