301239 Moisture Stop, Concrete Sealer, 1 Gallon

Rust-Oleum Moisture Stop is a penetrating concrete sealer designed to protect concrete surfaces from moisture damage, salt deterioration, and other contaminants. Unlike surface coatings and paints, this sealer penetrates deep into the concrete, chemically reacting with the free calcium and minerals to form a protective gel barrier within the pores, capillaries, and cracks. This sealer is ideal for driveways, patios, basement floors, and other concrete surfaces that need protection from water ingress and moisture-related wear.

By sealing concrete from the inside out, Moisture Stop allows previously uncoatable surfaces—those with moisture issues—to be successfully coated with additional finishes. The product maintains the natural appearance of concrete with a subtle satin finish, preserving the original look while adding durable protection.

Features and Benefits

• Deep Penetration: Penetrates concrete pores and reacts with minerals to form a protective gel barrier within cracks, pores, and capillaries, rather than sitting on the surface like paint.
• Moisture and Salt Protection: Prevents water ingress and contaminants, extending the service life of driveways, patios, and other concrete surfaces.
• Suitable for Multiple Surfaces: Works on concrete driveways, patios, floors, and other masonry applications.
• Natural Appearance: Maintains the original look of concrete with a satin finish that enhances rather than masks the surface.
• Prepares Uncoatable Surfaces: Allows moisture-affected concrete to be sealed and prepared for additional coatings.
