A water based mineral silicate primer primarily for use with Porter's Mineral Paint, particularly when a surface has been patched, repaired or has varying degrees of porosity.

Mineral Silicate primer is also excellent for us as a penetrative primer for new unpainted interior set plaster, and to bind surfaces on very aged, powdery or chalky lime washed or cement based paints. Can be used either prior to repainting with the same product, or to prime/bind surfaces when moving on to another paint system.
