Waterproofing Block at the Bruneau Observatory | PRO Painting Tips

What happens here

Load the Valspar Protective Sealer Natural Look into a TriTech airless sprayer. Use a fine-finish tip, specifically an HEA 311 (High Efficiency Airless), and set the sprayer to a super low pressure. The goal is to saturate the cinder blocks, not to atomize the product or create significant overspray. Spray the exterior cinder block walls, working systematically. Ensure the product is applied evenly to fully penetrate and seal the porous block surface. Apply to the entire surface, taking the seal down to the footings to ensure weather-proof sealing all the way to the ground. For this specific project, the contractor requested sealing two blocks up from the ground.

Goal: Apply the silicone-based sealer to the exterior cinder block walls using a TriTech airless sprayer with a fine-finish HEA 311 tip at low pressure, ensuring thorough saturation and minimal overspray.
