Alkali Resistant Plaster Primer

A solvent-base pigmented primer recommended for both interior and exterior plaster. With alkali-resistance for use on sound cement, concrete and brick substrates. Provides adhesion for subsequent top-coats and provides good opacity over most surfaces. Do not apply to damp surfaces (e.g. newly rendered plaster or cement). This product must be used in conjunction with either Excelsior Bonding Liquid or Excelsior Surfcon if the surface is very powdery or friable. Suitable for Rhinolite or Gypsum plaster.
