Waterproofing: the Invisible Half
Tile is the pretty 10%. This page is about the dry 90%.
Ask any bidder two questions: 'what board goes behind the tile, and what membrane goes on the board?' If the answer is greenboard and nothing, keep shopping. Here is our specified assembly for Wethersfield tub surrounds, why each layer exists, and the photos we take mid-job so you never have to take our word for it.
- Cement board substrate. Won't swell, soften or feed mold when wet.
- Bonded membrane. Paint-on or sheet membrane over every wet-area square foot.
- Sealed penetrations. Valves, spouts and fasteners gasketed, not just grouted around.
- Movement joints. 100% silicone at corners, tub line and ceiling — grout cracks there.
- Photo documentation. You see the waterproofing before tile covers it. Always.
Wethersfield notes
In Wethersfield we photograph every membrane coat with that day's date: Old Wethersfield owners want the 1920s tile saved, not smashed — regrout-first is the pitch that wins the historic streets. Dry walls are a system, not a material — and the system is what our workmanship stands on.
