SILCACON first coat 5L
SILCACON first coat / deep primer serves to treat the surface of the SILCA® 250KM insulation boards before applying the lime plaster and smoothing lime and should also be applied to the surface before bonding different boards. The first coat reduces the capillary activity of the SILCA® 250KM board and thereby slightly hardens the surface.
SILCACON first coat is died with clean water in a ratio of 1:2 / 1:3 and can be applied by brush, roll or spraying device. The treated surface becomes slightly blue, for further treatment the surface must be dry. The working environment must be sufficiently ventilated. As long as the first coat has not dried, the working equipment can be cleaned with water.
