If you're going to put a new floor over an existing floor that's uneven, you need to level the surface flat before you start, or you'll run into problems later. Tile, wood and even carpeting won't lay right if the base floor under it isn't even. Floor leveling compound is a kind of cement, but thinner, so it spreads out and levels itself as you pour it, evening out whatever surface it's applied to. Mixing ratios and drying times vary between brands, so consult the packaging for additional information.
Things You'll Need
- Household floor cleaner
- Long carpenter's level
- Floor leveler in powder form
- Power drill
- Mixing bar for the drill
Use household floor cleanser and a mop to clean the floor completely. Let it dry for 24 to 48 hours.
Lay the long level on the floor and begin moving it slowly, on its narrow edge. Study the surface of the floor where it meets the level, looking for gaps to indicate low spots and dips in the floor.
Mark circles around the lower spots and dips with your pencil.
Mix your floor leveler in a bucket with water, in the ratio recommended on the package (it will vary from brand to brand). Mix enough to cover all the dips and low spots on the floor.
Pour leveler over each low spot on the floor, as indicated by the marks you made. Pour it slowly, so it spreads out and fills the areas. Let it set overnight.
