Can I use this Silicate Primer over conventional painted surfaces?
No, the Silicate Primer just won't "bond" to previously painted surfaces. However, Earthborn Silicate Masonry Paint can now be applied over conventional ‘plastic’ masonry paints with the use of Earthborn's new Bonding Primer. Which means you can get a totally colour co-ordinated look for all your buildings! Note though, the Bonding Primer is not breathable.
