How to Waterproof Drywall for Tile

If you’re planning to tile over drywall in your bathroom, kitchen or any other room in your home, it’s important to waterproof the drywall first. Otherwise, the water from the tile could seep through and cause damage. Waterproofing drywall is a fairly simple process that anyone can do with the right materials and a little bit of know-how.

Here’s what you’ll need: -A pail of clean water -A sponge

-A putty knife or old credit card -Liquid latex waterproofing membrane (available at most hardware stores) -A paintbrush (1″ or 2″ is best)

-A roller with an extension handle (optional) Step 1: Start by giving the area a good cleaning. Use the sponge and pail of clean water to remove any dirt, dust or debris from the surface.

If there is any mildew present, you’ll need to treat it with a mildewcide before proceeding. Step 2: Once the area is clean and dry, use the putty knife or credit card to apply a generous amount of liquid latex waterproofing membrane to all of the seams where sheets of drywall meet. Be sure to get into all of the nooks and crannies so that no water will be able to get through.

You can also apply membrane around any penetrations such as electrical outlets or plumbing fixtures. Step 3: Once all of the seams are sealed, brush or roll on a layer of membrane over the entire surface. This will create an additional barrier against moisture.

Be sure to let each coat dry completely before applying another. Depending on how much coverage you need, you may need to apply 2 or 3 coats total. And that’s it!

Can You Waterproof Drywall for Shower

If you’re planning to tile a shower, you need to make sure the drywall behind it is properly waterproofed. Otherwise, your shower will be susceptible to mold and mildew growth. Waterproofing drywall is relatively simple.

You just need to apply a waterproofing membrane to the surface of the drywall before tiling. There are two main types of membranes: liquid-applied and sheet-applied. Liquid-applied membranes are applied with a brush or roller and then left to cure.

They’re typically made of latex or acrylic and provide good protection against water damage. Sheet-applied membranes are adhered directly to the surface of the drywall with an adhesive. They’re usually made of butyl rubber or EPDM (ethylene propylene diene monomer) and provide excellent protection against water damage.

Once you’ve applied the waterproofing membrane, you can tile over it as usual. Make sure to use tile spacers between each tile so that there’s room for movement if the underlying substrate expands or contracts due to moisture changes.
