How to Even Out a Floor With Missing Tiles

Missing floor tiles can be replaced with underlayment.

You want to cover up an existing tile floor with new tile or other flooring. The problem is, some of the tiles are missing. If the flooring is old, you won't be able to buy replacement tiles. So you'll need to fill in the spaces to level the surface and even out the floor. If you don't do this first, the holes from the missing tiles will cause the new flooring to lay unevenly. New tiles can crack, chip and break after they are walked on for some time.

Things You'll Need

• Vacuum cleaner with brush attachment
• Small bucket
• Trowel
• Self-leveling underlayment

Instructions

1. Use the brush attachment on your vacuum cleaner and thoroughly vacuum out every area where there are missing tiles. All dirt, dust and debris must be removed for the underlayment to stick well.

2. Read and follow the package directions on the self-leveling underlayment. The underlayment will usually come in powder form and must be mixed with water to make a thick paste. If the mix is too thick, add more water. If it's too thin, add more underlayment powder. You can use a trowel to mix the underlayment.

3. Even out a floor with tiles that are missing by applying the underlayment. Scoop it out with the trowel into the first square. Spread it out evenly; add more as needed until the opening is full. You can fill it up to one inch thick. Use the side of the trowel to level the underlayment with the tiles around it.

4. Fill the remaining spaces with the self-leveling underlayment. Allow it to set undisturbed according to the package directions. It needs to be thoroughly dry before you cover it with tile, carpet or other flooring.
