Note: Actual coverage will vary depending upon application method, surface texture, and porosity.

Any previous film forming (Non Penetrating) coatings must be removed. The surface should be clean, dry, and free from dirt, mildew, and all loose particles. Cracks, holes, and loose mortar joints should be repaired using a suitable concrete patch or mortar mix. For best results, Sikagard®-215 Siloxane 7 should be applied following a rain-free period of at least 2 days.

EFFLORESCENCE, a white, powdery, crystal-like deposit visible on the masonry surface, must be removed. Muriatic acid, used according to manufacturer’s directions, is effective efflorescence removal agent. All masonry surfaces are subject to occurrences of efflorescence.

No mixing required, the product is ready-to-use. Just shake the pail throughly before applying.

DO NOT THIN.

Protect glass, wood surfaces, and shrubbery from overspray. This product will not damage asphalt shingles. The most effective method of application is the use of an ordinary garden pump sprayer. Eliminate most of the pressure at the spray nozzle and operate at the lowest practical pressure on the tank. The nozzle should be opened to a coarse spray adjustment. For even flooding of material, start at the bottom of the wall and hold the spray at an angle to avoid splashing. It is important to hold the spray tip close to the surface to avoid streaking. If Sikagard®-215 Siloxane 7 is applied with a brush, flow on liberally, do not brush out, to ensure even flooding of the surface. If a second coat is applied, apply wet on wet within 5 minutes. Apply only when air and surface temperatures are 10 °C (50 °F) or higher.
