EWI-333 Topcoat Primer

Product Overview
Top Coat Primer is a stabilising render primer designed to prepare the basecoat prior to the application of EWI Pro Silicone Renders. It facilitates the application of render coats and enhances adhesion to the substrate, helping to create a long-lasting finish that will withstand the test of time. Top Coat Primer can be pigmented to match the colour of the selected render.
Intended Uses
Top Coat Primer is used to prepare walls before the application of coloured render. It improves adhesion of the render to the basecoat, aiding application and reducing absorbency at the groundwork stage.
