NAC PFI Preformed Inside Fabric Corners

The NAC PFI preformed inside corners are ready-made fabric pieces that lock down the inside corners of a waterproofing membrane assembly — the spots where a flat sheet can't fold clean and leaks love to start. They take the guesswork out of detailing corners on showers, decks, and wet areas.

Embed each preformed corner into the membrane or coating at inside 90-degree corners, then finish over it as part of the system. They're built to match NAC waterproofing assemblies and speed up the fussiest part of the waterproofing step.

Pros know corners are where waterproofing fails, so they detail them right the first time. Tile Outlets stocks NAC PFI preformed inside corners so your membrane details hold.
