Render Primers

We currently sell two types of render primers. Firstly, the EWI-333 Topcoat Render Primer is an external wall primer designed for application directly onto a reinforced basecoat prior to the application of our silicone-based renders. Secondly, the EWI-330 Mineral & Acrylic Primer is designed for application prior to our Acrylic and Mineral primers. These external primers are ideal for bonding dusty substrates, are vapour permeable and help to facilitate the application of the render.
