How Do You Fix Uneven Floors?

Fix an uneven floor by hammering or sinking in any nails that have popped up, sanding the area, adding latex floor filler and sanding the floor again. This can take more than a day. You need a hammer, a 36-grit sander, latex floor filler and 50- and 100-grit sandpaper.

  1. Hammer in nails

    Go over the floor, and hammer in any nails that are not flush with the floor.

  2. Sand the floor

    Use a 36-grit sander to sand the floor. Sand the floor first diagonally and then parallel to the floor boards. Sand the edges using a floor edger.

  3. Vacuum up the dust

    Vacuum up any sanding dust.

  4. Apply latex floor filler

    Add water to latex floor filler until it is no longer viscous. Use a rubber grouting float to spread the filler across the entire floor. Allow the filler to dry.

  5. Sand the floor

    Sand the floor and edges with 50-grit sandpaper. Run the sander parallel to the floor boards.

  6. Check on the filler

    Make sure that the filler has not lifted from the floor. If it has, add more filler to the areas.

  7. Sand the floor again

    Sand the areas that you refilled with 100-grit sandpaper. Stain the floor if needed.
