What Subfloor Works Best with Self Leveling Compound
Self leveling compound is used to smooth and strengthen any loose OSB, wood or plywood subfloor. The type of floor determines which type of subfloor will work best.
What Causes Uneven Floors?
Some of the most common causes of humps and valleys on the floor are joists that come about due to the twists and flex that take place over time.
Precautions to Take when Using Plywood as a Subfloor
As much as plywood will work best with self leveling compound, you must make sure that you seal all the joints that may be evident in the plywood to prevent any risk of leakage. The other option would be to get a sizeable layer of rubber to support the plywood. This will give the floor some flexibility to withstand any expansion or contraction that may result from temperature changes.
How Poor Self Leveling Affects Floors
If you make the mistake of putting concrete floor tiles without a proper self leveling compound, the floor will develop humps which will result in cracks in the tiles. In the case of wooden floor tiles, the result is a swelling that pushes some tiles leaving the wooden tiles protruding dangerously.
