How To Waterproof Bathroom Floor

A common misconception is that bathroom floor materials are already waterproof but that s not always the case.

How to waterproof bathroom floor.

Dab caulk onto nail or screw heads to seal the potential leak point they provide. Lay the membrane down so that half is on the wall and the other half on the bathroom floor covering the crack. Tile is your best bet for keeping water from seeping through to floor boards. Use a paint roller to evenly apply primer over the floor starting from a far corner and working around the edges of the room first.

Caulk any seams where two pieces of plywood are butted together. If you are waterproofing a shower recess apply primer at least 6 feet up the wall. Allow the caulk to dry for 24 hours before installing the finish flooring. The membrane is then painted across walls and floors using a roller.

Then continue applying the primer to the rest of the bathroom floor. Tile and linoleum can sustain damage from water emergencies like an overflowing. To fully waterproof the room apply primer to the walls as well up to about half a foot from the floor. To stick the membrane down use either a paint roller or brush to paint over it with the waterproofing agent.

Using a paint roller or brush start applying the primer in even strokes. The waterproofing membrane is normally applied under the edges of the polyfab bandage to ensure that it s fully soaked through and to make sure it properly adheres to the wall or floor. Slate marble and granite are just some examples that you can use for waterproof bathroom flooring. Caulk any splits in the wood or any other areas that may provide a point for water to seep under the subfloor.

Honed tile is slip resistant and larger grout lines will also give you better traction. You ll want to coat about 7 or 8 inches of the wall with primer and waterproof sealer to ensure your bathroom is fully proofed. Start in the back corner and work around the walls first. Ensure that the stone tile you choose is high in quality so it won t discolor or get damaged easily.
