Product Overview

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.

Hello, This is a clear solution and awesome for wood. It is much better than Thompsons Water-Seal as it is made of inorganic polymers that will lat longer than Thompson's. It is water-based as well and will repel water.

can this be used on basement floors& walls inside to stop water leaking

Asked by: loose
This product is more of a positive side water-repellant vs negative side. This means that if your trying to block penetration from the outside of the wall it will do a better job than if it is applied to the inside of the wall and the moisture is coming from within the wall. It will help slow it down but it is a positive side water-repelling product.

Can this be painted over?

Asked by: TracyW
This product is designed to be used as a penetrating sealer. This means that it leaves the surface texture available but seals more internally to the substrate. I have coated over it and it has held up pretty good. I recommend testing it out. This material comes from the silicone family so siliconized paint is even more compatible.

It's more like kleen strips eco paint thinner. It absorbers into surface but does not hold back water at all. I applied 4 coats all according to instruction. Doesn't work as advertised waste of money.

Rated 2 out of 5 by from 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.

Rated 2 out of 5 by from Doesn't do all it claims I bought this product to seal/waterproof my wood subfloor before hardwood floors being installed. This product claims to be able to waterproof many materials, wood for included. It did not work for me. I had to buy another product to waterproof the wood.

Rated 4 out of 5 by from would buy again easy to put on but you have to be careful with using too much.

Rated 4 out of 5 by from 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.

Rated 4 out of 5 by from Good Value..... Used to waterproof for new flooring on cement floor that is on grade. Have not noticed any moisture so far, but it has only been a couple of weeks. The product is very easy to use and is considerably less expensive than other products we researched. We used a paint roller and applied a rather thick coat, and it dried to the touch in about 2 hours. The only reason for the 4 star rating is the length of time it has been down.
