Surface preparation

Clean the surfaces to be treated. Remove loose and poorly adherent old paint. Remove brittle, old surface layers. Clean with e.g. pressurised hot water or water-sand jet. Remove the laitance from new concrete surfaces. When preparing and painting substrates containing asbestos, regulations given by authorities must be followed. The needed repairs are done with suitable plaster. New surfaces must be allowed to dry for at least 3 months before they are painted.


Before use stir the paint thoroughly. Apply by brush, roller or airless spray. Suitable nozzle for airless spray is 0.017 - 0.021". If required, dilute the paint 5 - 10 % by volume, e.g. for lime wash surfaces and when repainting the ceilings of industrial halls. SILOKSAN PRIMER can also be left as top coat, e.g. on industry hall ceilings. The top coating is done at the earliest after 2 hours in good conditions with SILOKSAN FACADE Silicone Emulsion Paint. Indoors the finishing can be done with other paints depending on the object. In cool and humid conditions the top coating is done at the earliest the next day.
