Masonry Wall
Masonry walls (brick, concrete block, stucco, cast-in-place concrete) need a coating system that bonds to high-pH substrates, breathes to release moisture vapor, and flexes with the natural movement of mortar joints. The GAF masonry wall line is built for that profile.
For chalky or porous masonry, SureBond Primer is the field-default. For most concrete and block, GAF Multi-Purpose Primer is enough. Top with an elastomeric or acrylic coating sized for the wall exposure (south and west walls take the most UV; north walls hold the most moisture). Factory-direct from a GAF-authorized distributor.
