Earthborn Bonding Primer is a white water based primer for use with Earthborn Silicate Masonry Paint. It can be applied to exterior masonry surfaces which have been previously painted with conventional masonry coatings and it will provide a long-lasting bond or the Earthborn Silicate Masonry Paint.
As a primer and bonding agent for Earthborn Silicate Masonry Paint on all non breathable or poorly absorbent surfaces. Suitable for all sound and stable old coats of paint.
Can it be used along side the Earthborn Silicate Primer?
Yes! The best way would be to spot the patches where the previous paint cannot be removed with Bonding Primer. (Please be aware that these patches will not be breathable).Then prime the rest of the unpainted area with the Earthborn Silicate Primer.
For the second coat you would apply a mixture of 20% Silicate Primer & 80% Silicate Masonry Paint over the whole area including all areas that have been spot primed. You would then finish off with one final coat of the Silicate Masonry Paint.
