Bostik Cementone Render Stabilising Primer - Grey - 10L

The main benefit is that it provides an excellent key for render and stabilizes exterior surfaces, leading to better adhesion and a faster, easier finish by eliminating the need for scratch coats.

Yes, it can be used indoors on surfaces like glazed tiles before plastering to improve adhesion.

No, the Bostik Cementone Render Stabilising Primer is ready to use and requires no mixing.

It is suitable for both porous and non-porous exterior surfaces, including concrete, brickwork, and existing render. It is also compatible with interior surfaces like glazed tiles.

The primer is grey, which helps you see where it has been applied. Aim for an even, consistent coat across the entire surface to ensure controlled application and optimal performance.

Clean your brushes, rollers, or sprayers immediately after use with water.

Store in its original, tightly sealed container in a cool, dry place, away from direct sunlight and frost.

Ensure the surface was properly cleaned and free from dust, oil, or grease before application. Reapply primer to any missed spots.

Check if the primer was applied evenly. Uneven application can lead to inconsistent render adhesion. Ensure a consistent coat was applied with no gaps.

The surface may not have been adequately stabilized. Apply a second coat of primer if necessary, ensuring full coverage.

This is often due to inconsistent application. Ensure you are using a consistent technique with your brush, roller, or sprayer and can see the grey colour covering the surface evenly.
