Product Info

Siloksan Primer is a white spirit dilutable vinyl primer for problematic substrates. It is designed for priming old lime plaster and lime wash surfaces. The primer penetrates the substrate and binds the porous surface layer.

Siloksan Primer is a white, flat paint that can also be used indoors for whitening the ceilings of old industrial halls, for example. In normal conditions, this quick-dry primer can be top coated after a few hours with Siloksan Façade.

All Siloksan products have CE approval.

Surface Preparation

New Surfaces - New concrete element or cast surfaces can be painted with Siloksan Façade 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.

Previously Painted 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 an 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.

Application

Priming - Before use stir the paint thoroughly. Prime clean and solid mineral surfaces with Siloksan Façade Silicone Emulsion Paint with an addition of SILOKSAN GEL (9 : 1). For priming the paint may be diluted by 5 % with water. This priming can also be used for previously painted surfaces.

Top coating with undiluted Siloksan Facade silicone emulsion paint - Reserve a sufficient amount of paint of the same batch for each uniform surface to prevent possible colour differences. If different batches must be used, possible seams between the batches are placed as inconspicuously as possible and are painted with a mixture of paint from both batches (e.g. 1 : 1). Apply by brush, roller or airless spray. Suitable nozzle for airless spray is 0.017 - 0.021".

Application Conditions

During the application and drying period the temperature of the ambient air, the surface and the paint shall be above +5 °C and the relative air humidity below 80 %.
