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.

We applied with a pump sprayer as was noted on instructions, once I received product. Unfortunately, I assumed that it was thicker, like paint. It was not. I applied to basement walls and it is not visible so was not the finished product I was looking for.

Works great. Put this on my drive July 2018, and my drive is still mold free (1yr later). Applied it two weeks ago to my patio and front walk way. I intentionally left two areas untreated to see how fast the mold returns. It took less than a week for discoloration to begin in the untreated areas. WOW> Note to buyers...You have to wait the 48 hrs for cure time. Be careful not to walk on it as it will get on your shoes. If you go inside, it will make your floors SLICK. It is pricey but full performs as you would want.

Product does not work at all. 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.

    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.

      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.

      Saturated a piece of paper towel. Let dry for 36 hrs. Water went right through paper towel.
