Description
Armor WL550 is a solvent-based, penetrating water-repellent sealer for unsealed concrete and masonry surfaces. It chemically reacts below the surface to form a hydrophobic barrier and slightly darkens the surface for a matte wet-look finish without a visible surface film or coating.
It can be used on interior and exterior poured, broom-finished, and stamped concrete, brick, bluestone, flagstone, granite, slate, natural stone, and masonry. Apply to a properly cleaned and prepped unsealed surface with a pump sprayer.
- Coverage: Up to 175-225 ft2/gallon
- Water and other liquid absorption reduction: Up to 95%
- Protection duration: Up to 5-7 years
- Resealing: Apply a single coat to a clean, dry surface
- Suitable applications: Driveways, walkways, patios, sidewalks, curbing, walls, building exteriors, and roofs
