SILIKON FASAD Silicone facade paint

SILIKON FASAD is a silicone water-dispersion paint for first-time and repair painting of facades. It goes over rendered, concrete, stone, brick and aerated-concrete surfaces and silicate brick.

Vapour out, water off

The silicone binder solves what ordinary acrylic cannot: the film passes water vapour from inside the wall while repelling rain from outside. Moisture leaves the structure instead of freezing inside the render in winter and tearing the coating off in sheets.

Insulation systems and mineral wool

That is why this paint goes on facades insulated with mineral wool: the insulation has to dry outwards, and sealing it under an impermeable layer ruins the whole system. The same logic applies to historic buildings and listed architecture, where walls must breathe, and to seaside sites with constant damp and salt in the air.

How long it lasts and how to clean it

The declared facade protection is over 15 years. The coating can be washed with detergent, so a facade by a road, or a plinth, is cleaned rather than repainted.

Indoor use

The paint may also go on interior walls where high vapour permeability is needed.

Consumption on different substrates

The data sheet gives 150–200 g/m² per coat on non-absorbent substrates and 180–220 g/m² on absorbent ones. Smooth concrete and a previously painted wall sit at the low end; fresh mineral render, aerated concrete and silicate brick sit at the high end because they drink the first coat. A primer evens that out and pays for itself on a large facade.

Colour and limitations

The paint is white, with a transparent base (TR); tinted in POLIFARB Color System and with COLOR MIX pastes. Metal is painted only after an anti-corrosion primer. Fresh plaster can be painted only after 3–4 weeks, concrete after a month. The paint is not compatible with sand-cement renders whose pH is above 10 at the time of application. Apply 2 coats with 2 hours’ drying between them; the coating can be washed no earlier than 7 days after application.
