Waterproof and protect your concrete and masonry surfaces with ProteShield 1-Gal. Elastomeric Waterproof Sealer. ProteShield's water-based, inorganic elastomeric polymer formula leverages an advanced rubber silicone component that penetrates porous surfaces and yields a protective and highly durable film. ProteShield will not yellow, crack or delaminate. Prevents damage caused by freeze-thaw, cracking, spalling and water-intrusion. Protects against ultra violet rays, ice, water-intrusion, chlorinated water, salt water, acid rain, salts and other chlorides, rust, mold, fungus, mildew, algae, insects, oil, fuels, stains and excessive temperatures. Recommended for many porous surfaces, including concrete, masonry, pavers, brick, precast concrete, plaster, drywall, GFRC, gypsum board, stone, tile, ceramics, foam, canvas, veneer, overlays, asphalt, wood and most types of metal (e.g. copper, brass, steel, aluminum, gold, iron). Commonly used on large (commercial) horizontal applications, including theme parks, city parks, parking lots, airports, roads, highways, bridge decks, piers, schools, helipads, tunnels, pipes, decks, walkways and driveways. Commonly used on large vertical applications, including (above and below ground) foundation walls, sound barriers and retaining walls, fencing and towers.

  • Elastomeric component of formula has elongation of 325% and up to 400% elasticity that allows for flexibility as treated surfaces changes or moves
  • Covers approximately 200 sq. ft. per gallon
  • Impermeable finish creates a barrier that prevents water intrusion (0.01 g/h/cf)
  • Industrial grade formula is resistant to extreme temperatures from -65 degrees F to 400 degrees F
  • Highly durable finish dries quickly and may be walked on 1 to 2 hours after initial cure
  • Matte, non-glossy finish maintains natural beauty of surfaces
  • Penetrating formula bonds tenaciously to porous surfaces to prevent growth and penetration of mold, mildew, pollution, sewage, oil, and wax build-up--making maintenance much easier and convenient
  • Non-VOC formula minimizes bothersome odors
  • Ready-to use formula with no additives
  • Easily applied with standard roller, pump sprayer equipment or a brush
  • Durable finish does not require seasonal recoats
  • Ideal for interior and exterior applications
  • Silicone/rubber formula restores, seals, protects and prolongs the life of many porous surfaces

Rated 3.8 out of 5 by 4 reviewers.
Rated 2 out of 5 by Does not seal porous stone / concrete. Tried sealing slabs of porous sandstone held together by concrete for birdbath. Followed instructions and gave 48 hours to cure. Filled birdbath (very low water pressure) leaked just as fast as it did before applying this product. This might work in other applications, but I would not use it based on no difference noted even after careful application. 5 stars for Home Depot Customer Service! I had used only a quarter of the bottle, and so I took it back into the store (I'd ordered it online, shipped to my house). No hassle to return and get store credit. Very glad about that, because it is $60 a bottle. I already happily spent half the credit that day. Glad the Home Depot stands behind the items they sell. June 24, 2014
Rated 5 out of 5 by Waterproof Sealer Excelent product ... easy to apply. When applied properly, prevents moisture from seeping through block. September 16, 2014
Rated 4 out of 5 by Easy To Apply & Clean-Up Applied product easily with a brush. repelled water after testing with spray after a 4 day cure time. Did not change color of the concrete after curing. I applied a rubberized coating on top of this, after a week, to the portions of the wall that were going to be underground. I hope it holds up over time. November 2, 2013
Rated 4 out of 5 by would buy again easy to put on but you have to be careful with using too much. September 17, 2013
