Unlike ordinary paint that simply adheres to a surface and can be forced off by incoming water pressure, DRYLOK Extreme Masonry Waterproofer actually penetrates the pores in that surface, bonding to the masonry and creating an impenetrable barrier. If water is leaking through existing masonry or you need to protect new construction, DRYLOK Extreme Masonry Waterproofer's proprietary formula is GUARANTEED to stop water.
- Size: 1 gallon
- GUARANTEED to stop water – withstands 15 pounds of hydrostatic pressure (PSI), equivalent to a wall of water 33 feet high
- Helps protect against radon gas penetration by reducing vapor transfer
- Green Wise certified
- Low-odor formula complies with all current VOC requirements
- Breathable film will not trap moisture in the masonry
- No pre-mixing or pre-wetting
- Easy cleanup with warm, soapy water.
Specifications
- Coverage: 75-100 square feet per gallon
- Dry time: 1-2 hours
- Recoat time: 3 hours.
