Product Overview

Bostik Render Stabilising Primer with Plasprime® Technology (formerly known as Cementone Renderer Stabilising Primer) has been specially developed for the rendering and plastering professional. It primes and stabilises most exterior surfaces, prior to the application of new render. It is grey in colour for easy application and contains approximately 20% recycled material.

Bostik Renderer Stabilising Primer is suitable for outdoor use on both porous and non-porous areas to give a surface that dries evenly giving excellent adhesion and a faster, easier finish. Bostik Renderer Stabilising Primer has been developed for preparing exterior walls prior to applying render. It can be applied over brick, blocks, concrete, plaster and render. When rendering externally it removes the need for initial scratch coats, only receiving render is required. Bostik Renderer Stabilising Primer can be used on internal shiny surfaces such as glazed tiles before plastering.
