What happens here
Load the TriTech airless sprayer with the Valspar Protective Sealer. Set the sprayer to a low-pressure setting and use a fine-finish tip, such as an HEA 311, to minimize overspray and atomization. Apply the sealer in even, overlapping passes, moving the spray gun methodically across the cinder blocks. The goal is to saturate the blocks thoroughly. Work your way down from top to bottom, ensuring coverage extends all the way to the footings for complete waterproofing. A second coat can be applied to the bottom two blocks for enhanced protection. Visually inspect the wall for complete and even coverage, as the wet sealer will temporarily darken the blocks.
Goal: Apply the Valspar Protective Sealer to the exterior cinder blocks using an airless sprayer with a fine-finish tip at low pressure, ensuring thorough saturation of the porous block material.
