Alkali Resisting Primer

Johnstone's Trade Alkali Resisting Primer is a solvent-based primer and sealer for interior and exterior use on new or bare plaster, concrete, cement, render, or wood and metal surfaces. It is suitable for interior and exterior use, and provides exceptional resistance to alkali attack when used as a primer on unpainted surfaces, or as a sealer on powdery substrates. Our Alkali Resisting Primer will cover approximately 9-11 square metres per litre, depending on the nature and porosity of the surface being painted, and is recoatable after 16-24 hours under normal drying conditions.
