This 100% actives silane sealer is the deepest penetrating, longest lasting and highest actives stucco sealer we offer. It is best used as a primer or bonding agent before painting stucco that has never been painted. It can also be used as a water repellent sealer on natural stucco to resist wind driven rain, moisture intrusion and weathering. It will also stunt mold and mildew growth making the organic growth easier to clean.

Available only in a ready to use version, two coats are easily applied wet-on-wet with a sprayer, roller or brush.
