Rust-oleum 100001 Clear Acrylic Waterproofing Sealer 1 Gal

Product Description

The RUST-OLEUM 100001 is a clear acrylic waterproofing sealer formulated for vertical brick, masonry, and concrete surfaces. It penetrates and seals porous substrates, blocking moisture intrusion while leaving a clear finish. The formula doubles as a bonder coat on difficult-to-seal surfaces and binds chalky material that would otherwise prevent adhesion. Dry time is 60 minutes, and the surface becomes paintable within 2 hours of application. Cleanup requires only water. Sold in a 1-gallon container, this sealer is a practical first-coat solution for masonry protection and prep work on both new construction and remediation projects.

This sealer is intended for vertical exterior masonry surfaces including brick, concrete block, and poured concrete walls. It is suited for residential and light commercial applications where surface sealing, moisture control, or a preparatory bonder coat is required before painting or coating. The fast dry time and water cleanup make it practical for single-day project workflows. Masonry contractors, waterproofing specialists, and experienced DIYers handling concrete and brick restoration work are the primary installers.
