Bonding Primer

Our 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 creates a strong mechanical bond, helping the paint grip to the surface.

For internal use, apply before Earthborn Claypaint to even out differences in surface absorbency.

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