Before laying tile or any other material on a wooden shower bench, waterproofing the wood gives it an extra edge against water penetration aside from the waterproofing sealant you place on tiles after you finish laying them. Even though your wood will most likely sit below a layer of mortar and tile, humidity still reaches it and eventually destroys it as time passes. While many waterproofing methods exist for wood, not all of them interact well with mortar or other adhesives placed over them.

  1. 1

    Open your container of epoxy sealant and pour it into a plastic cup. Some epoxy sealants require that you mix two components. If your epoxy has an "A" and "B" container, mix them well inside a plastic cup using a long stick without getting any of the mixed product on your hands. Keep your distance if the smell disturbs you. Only use the amount of epoxy you think you need for the surface area you want to cover. Don't worry about underestimating the amount of epoxy you need, as you can make more if you fall short.

  2. 2

    Dip a paintbrush in the finished mixture and quickly paint over the surface of the wood. Cover the entire surface, including corners and margins. Don't miss a spot or else you will have covered the wood for nothing. Allow 24 to 36 hours for the epoxy sealant to dry completely before continuing.

  3. 3

    Repeat the process to apply a second coat and allow it to dry for a day.

  4. 4

    Sand down the epoxy mixture using 120-grit sandpaper to even out the surface. Get rid of all the bumps and droplets that appeared while the epoxy was drying.

  5. 5

    Clean all the dust from the surface with a dry brush and throw it away. Your shower bench now has full water protection and you may continue working on it.

Tips and warnings

  • Always keep one extra container of epoxy at hand just in case you need more to finish the job.
