Weight: 21kg
EWI-333 Silicone Silicate Primer is a deep-penetrating primer used to prepare substrate surfaces to create an artificial key prior to applying silicone and silicone silicate renders. It is a water-based primer containing acrylic polymers, quartz aggregate, pigments and enhancers and reduces the absorptive capacity of the substrates and aids the adhesion of the render. EWI-333 doesn't compromise breathability of the surface and helps to give a long lasting finish.
