Primax is a specially formulated 100% acrylic water-based primer, which ensures excellent adhesion and alkali resistance when bonding Dryvit adhesively-attached EWI systems to latex and oil-based painted surfaces. Primax also provides adhesion to glazed brick and tile or over high porosity substrates to reduce suction prior to applying a Dryvit levelling coat.
Primax can be used on properly prepared sound glazed brick or tile as well as previously painted masonry surfaces prior to the installation of Dryvit adhesively-attached EWI systems, provided that the paint is sound and well bonded to the substrate.
