Vorbehandlung

The substrate should be clean and free of dust, cement skin, grease and other impurities that can prevent adhesion. Adhesion and surface resistance of the substrate should be no less than 0.5 MPa. Always prime the underlying substrate with PP600 and allow to dry before pouring. In terms of the primer forming a film, the temperature of the substrate must not fall below 10 °C. For best results, the ambient temperature in the work area should be between 10 and 25 °C.

Vermischung

Mix CM 420 Offshore with max 4.3 liters of water (max 29 %) per 15 kg bag. Create the mixture with a drilling machine and a whisk, or a mixing pump intended for this purpose. The correct water mixture can be tested using a slump test with a cylinder with Ø 30 mm and a height of 50 mm on a 300 x 300 mm plexiglas plate. With the correct water mixture, the spread should be max 145 mm. The slump test also checks that the material is well blended and that there is no separation.

The mixed material is applied by hand, or pumped out onto the substrate in lengths and leveled with a toothed smoother. Each new ribbon is added to the old one as soon as possible so that the material can blend together and create an even surface. The width of the ribbons can be adjusted to the capacity of thwe mixing pump and the thickness of the covering. Use the Combimix form foam for edging. In order to avoid drainage pipes from getting clogged, always make sure the drains are properly sealed before pouring.

You can easily shape or cut the semi-hardened self-leveling underlayment material before it fully dries.
