EWI-212 High Polymer Render Coat is a polymer-modified, cementitious basecoat supplied in 25kg bags. It levels and stabilises backgrounds, providing a durable, high-adhesion foundation for subsequent render finishes. The workable, polymer-enhanced formulation suits both hand and spray application. It cures to a weather-resistant, vapour-permeable layer that can be lightly scratched for keying or floated to a smooth, even surface.
