Bonding Primer: For use over previously painted, sound masonry substrates. When used with Silicate Masonry Paint it will create a strong mechanical bond.

The Ecopro Silicate System requires all surfaces to be primed with a single coat of Ecopro Silicate Primer or Bonding Primer followed by two coats of Ecopro Silicate Masonry Paint (first coat over Silicate Primer must be diluted with 10-20% Primer). The paint and primer products form a chemical bond with underlying materials to create a water and weather-resistant barrier which enables the building to breathe. Ecopro Silicate Masonry paint can have a lifespan of up to 15 years. It can be used on interior and exterior mineral surfaces e.g. stone, masonry, concrete, pebble dash, plaster and sound silicate-based paint surfaces. It is especially suitable for renovations.
