Product Information
The GURU® W-S Patch Peel & Stick is a self-adhesive waterproofing patch designed to cover fastener penetrations in wall-only tile backer board installations. Its peel-and-stick construction allows direct application over screw locations as part of a waterproof wall assembly.
Each patch measures 4" × 4" and features a 20 mil thickness for consistent coverage over fastener penetrations. The patches are supplied in packs of 100 for shower walls and other waterproof tile backer board applications.
The peel-and-stick design installs directly over screw locations without requiring liquid-applied waterproofing or separate membrane patches. The W-S Patch Peel & Stick is intended for wall-only waterproofing systems where fastener penetrations must be sealed before tile installation.
