SILOKSAN FACADE

Silicone emulsion paint

  • UV resistant
  • Water-borne

SILOKSAN FACADE is a water-borne, full-matt silicone emulsion based paint for mineral surfaces. The paint is very permeable and water-repellent.

Use: New and previously painted facades outdoors, e.g. concrete, plaster, burnt brick, lime-sand brick and mineral boards. SILOKSAN FACADE silicone emulsion paint is easy to apply with roller or spray. Its binder composition prevents the paint from becoming brittle by the action of UV-light or heat. As SILOKSAN FACADE is water-repellent it keeps clean even in urban climate, and acid gases in the atmosphere do not corrode it. SILOKSAN FACADE can be overcoated the same day. It does not require any separate priming coat on most surfaces, when SILOKSAN GEL is added into the paint for the first coat.

Surface preparation

NEW SURFACES: New concrete element or cast surfaces: New concrete element or cast surfaces can be painted with SILOKSAN FACADE Silicone emulsion paint when a minimum of one month has passed after the casting, the surface is completely bound and no longer wet or matt moist. In measurements the moisture values of the concrete must be under 97% as relative humidity (RH) or 4 % as per cent by weight. It is recommended that new plaster surfaces are coated only after a hardening time of 6 - 8 weeks. Remove all dirt from the surfaces by cleaning with high pressure washer. When needed, add sand to the washing water or use a steel brush or similar in order to achieve sufficient surface profile (e.g. mould-cast surfaces). NOTE! When painting concrete elements take care of removing the laitance before painting. When preparing and painting substrates containing asbestos, regulations given by authorities must be followed. Brick surfaces: Remove loose matter, dirt and dust by e.g. hot water wash or RENSA FACADE facade cleaner according to the instructions. Allow the surface to dry thoroughly before painting. PREVIOUSLY PAINTED OR PLASTERED SURFACES: Remove flaking and poorly adherent or pulverized (e.g. lime wash) paint coats from previously painted surfaces. The method to be used is chosen depending on the strength of the substrate and the type of the paint to be removed (e.g. wire-brushing, hot pressurized-water cleaning or water-sand cleaning). Remove also poorly adherent, brittle plaster and concrete surfaces. Check the condition of the concrete seams and repair where required. If concrete constructions have cracks by the reinforcement bars, these cracks are to be opened by e.g. chipping or with a grinding machine. After this the concrete is roughened, if required. Clean all rust from the exposed steel bars and protect them with e.g. a coat of INERTA MASTIC epoxy coating. Use appropriate mortar, on plaster surfaces repair mortar, to repair the opened cracks and dents. Finish the repaired areas carefully and let them harden before they are painted.
