If water is leaking through existing masonry or you need to protect new construction, our proprietary formula is GUARANTEED to stop water. Unlike ordinary paint that simply adheres to a surface and can be forced off by incoming water pressure, DRYLOK® Original Masonry Waterproofer actually penetrates the pores in that surface, bonding to the masonry and creating an impenetrable barrier.


Waterproof interior, exterior, above and below grade walls and more: basements, living spaces, laundry rooms, dry storage, hobby corners, fish ponds, retaining walls, bird baths, and more.

  • GUARANTEED to stop water - withstands 10 pounds of hydrostatic pressure (PSI), equivalent to a wall of water 22 feet high
  • Fully transferable 10 Year Warranty
  • Resists 98 MPH wind-driven rain
  • Helps protect against radon gas penetration by reducing vapor transfer
  • No pre-mixing or pre-wetting
  • Low-odor formula complies with all current VOC requirements
  • Breathable film will not trap moisture in the masonry
  • Easy cleanup with warm, soapy water
  • White is tintable
