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.

Application Conditions

  • Application and setting temperature: from +5°C to +25°C.
  • Silicone Silicate Primer should be applied in temperate weather and not in temperatures above 30°C. Likewise, work should be postponed if the materials or the substrate are frozen.
  • The primer should not be applied in rain or humid conditions or if wet weather is expected before the wash has dried.
  • Drying time for primer is typically 12-48 hours, depending on the environment and humidity.
  • EWI-333 is available in 20kg and 7kg buckets.
