Bonding Primer

Earthborn Bonding Primer is a versatile water-based primer for interior and exterior use.

As part of the Earthborn Silicate Masonry Paint system, when applied over existing coatings, it forms a strong mechanical bond, helping the paint adhere to the surface.

If you have bare porous exterior masonry, you should use the Earthborn breathable Silicate Primer instead.

Internally, use as a wall primer to even out differences in surface absorbency. For example, where there are mixed substrates, e.g., lime and gypsum plasters or bare plaster and previous paint finishes that aren’t being removed. Without using a wall primer, slight colour and texture variations may appear, so applying a coat of Bonding Primer over the entire wall will resolve them before painting with Claypaint, Lifestyle or ECOPRO.
