DRYLOK® Extreme Masonry Waterproofer

USA’s #1 Selling Masonry Paint
15 Year Warranty

  • Prevents water from leaking through existing masonry
  • Protects new construction against water ingress and damage

DRYLOK® Extreme Masonry Waterproofer’s 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® Extreme Masonry Waterproofer actually penetrates the pores in that surface, bonding to the masonry and creating an impenetrable barrier.
