How to Prepare your Subfloors for Self Leveling Compound
Self-leveling compound is a great solution for uneven or damaged subfloors. It creates a smooth and level surface for the installation of flooring materials such as tile, hardwood, or carpet. However, in order for self-leveling compound to work effectively, the subfloor must be properly prepared.
Here are some steps to follow to prepare your subfloor for self-leveling compound.
Clean the Subfloor: The first step is to clean the subfloor thoroughly. Remove any debris, dirt, or loose material that may be on the subfloor. Sweep or vacuum the entire area and make sure it is completely clean before moving on to the next step.
Fill in any Gaps or Cracks: If there are any gaps or cracks in the subfloor, you will need to fill them in. Use a suitable filler material, such as a cementitious patching compound, to fill in the gaps and cracks. Follow the manufacturer’s instructions for mixing and applying the filler. Allow the filler to dry completely before moving on to the next step.
Sand the Subfloor: If the subfloor is uneven, you will need to sand it down. Use a floor sander with coarse sandpaper to sand down any high spots on the subfloor. Make sure to wear protective gear such as a dust mask and goggles when sanding.
Test for Moisture: Before applying the self-leveling compound, you should test the subfloor for moisture. Excess moisture can cause the self-leveling compound to crack or fail. Use a moisture meter to test the subfloor. If the moisture level is too high, you will need to address the issue before applying the self-leveling compound.
Prime the Subfloor: Once the subfloor is clean, level, and dry, you should apply a primer. The primer will help the self-leveling compound adhere to the subfloor. Follow the manufacturer’s instructions for mixing and applying the primer. Allow the primer to dry completely before applying the self-leveling compound.
Apply the Self-Leveling Compound: Finally, you can apply the self-leveling compound. Follow the manufacturer’s instructions for mixing and applying the compound. Pour the self-leveling compound onto the subfloor and spread it out evenly using a trowel or a squeegee. Work quickly, as the compound will begin to set in just a few minutes.
In conclusion, preparing your subfloor for self-leveling compound requires some effort and attention to detail. However, taking the time to properly prepare your subfloor will ensure a smooth and level surface for your new flooring. By following these steps, you can achieve great results and enjoy a beautiful new floor.
