From selection
to application.

Application

The prepared mixture is applied in a minimum of 2 layers onto the surface that is saturated with water with a brush, trowel or spraying machine. The layers should be homogeneous, smooth and even. The application should be done in the same direction on any specific layer. A new layer should be applied after the last applied layer dries off. The layers are applied in a perpendicular direction relative to the layer applied previously. Depending on the temperature 5 to 6 hours should pass before applying a new layer. A total application thickness of 2-3 mm will suffice. It is recommended to use waterproofing mesh or seal between the layers in order to improve the carrying capacity of the product. After the application of the last layer, the surface can be smoothed out with a dry sponge. After the last layer, the product should be protected from direct sunlight, air circulation and frost for 3 days. Product should be wetted and kept damp if needed.
