Can You Put Plywood Over Tiles?

Replacing tiles can be a time-consuming and expensive endeavor. If you're looking for a more budget-friendly and less labor-intensive option, you may be wondering if you can simply install plywood over your existing tiles. The answer is yes, you can put plywood over tiles, but there are some important considerations to keep in mind.

1. Preparation

Before installing plywood over tiles, proper preparation is crucial. The tiles must be clean, dry, and free of loose grout or adhesive. Any loose tiles should be secured or replaced. It's also recommended to apply a layer of self-leveling compound over the tiles to smooth out any uneven surfaces and create a more stable base for the plywood.

2. Underlayment

An underlayment is essential when installing plywood over tiles. It provides a layer of cushioning and helps prevent the plywood from cracking or warping. Choose an underlayment that is specifically designed for tile installations, such as a cork underlayment or a high-density polyethylene (HDPE) underlayment.

3. Plywood Thickness

The thickness of the plywood you choose depends on the size of the tiles and the intended use of the floor. For small tiles, a 1/4-inch plywood is typically sufficient. For larger tiles or heavy furniture, a thicker plywood, such as 1/2-inch or 3/4-inch, may be necessary.

4. Fasteners

To secure the plywood to the tiles, use screws or nails that are long enough to penetrate the plywood and the tiles. Countersink the fasteners slightly below the surface of the plywood to prevent them from snagging or causing damage to your flooring.

5. Flooring

Once the plywood is installed, you can install your desired flooring over it. This could be carpet, vinyl, laminate, or hardwood flooring. The type of flooring you choose will depend on your personal preferences and the intended use of the room.
