The Silicone Silicate Primer is a deep-penetrating render primer, designed to prepare the basecoat prior to applying EWI Pro Silicone Silicate Render. SiSi Render Primer facilitates the application of render coats and enhances its adhesion to the substrate, creating a long-lasting finish that will withstand the test of time. EWI-333 can be pigmented to match the colour of the render.
Silicone Silicate Primer is used to prepare the walls before the application of coloured render. It improves adhesion of the render to the basecoat, facilitating application and reducing groundwork absorbency.
