If you're laying ceramic, vinyl, wood planks or even carpeting over a plywood sub-floor, the surface has to be completely smooth and flat or it will cause various kinds of problems, depending on the type of top floor you're using. If the plywood is solid and relatively flat, then it's just a matter of leveling out the inevitable small gaps, holes and low spots in the surface. Floor leveler is a watery cement that levels out naturally and fills those problem areas.
Things You'll Need
- Household floor cleanser
- Powdered floor leveler
- Power drill
- Mixing bar for the drill
Vacuum the plywood thoroughly, picking up all dust and debris from the cracks and holes. Mop the surface with household cleanser. Let it dry completely.
Pour 1 to 2 inches of water in your bucket. Add enough powdered floor leveler to just cover the water.
Mix the solution with your drill and mixing bar. Add more water and powdered leveler, alternately, until you have enough to fill the low spots and gaps in the floor, and it's the consistency of thin soup.
Pour the leveler slowly over each hole, gap or low spot on the floor. Start at the corner of the room that's furthest from the doorway, so you can work your way out. Pour just enough over each area to fill it and let it spread out level.
Allow the leveler to set for 24 hours. Thoroughly sweep the floor to remove any surface dust. The floor is now ready for the top flooring.
