Top Coat Primer EWI-333

The Top Coat Primer is a deep-penetrating render primer designed to prepare the basecoat before applying EWI Pro Silicone Renders. Top Coat 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.

Intended Uses

Top Coat Primer is used to prepare the walls before applying coloured render. It improves the adhesion of the render to the basecoat, facilitating application and reducing groundwork absorbency.

• Drying time for primer is typically 12-48 hours, depending on the environment and humidity.
