Self Leveling Floor Compound Wood Subfloor

Self-leveling floor compounds, also known as self-leveling underlayments, are cementitious or gypsum-based materials used to level uneven subfloors before installing flooring materials such as tile, carpet, or hardwood.

For wood subfloors, self-leveling floor compounds can be a suitable option to address imperfections, level the surface, and create a smooth and flat base for the final floor covering.

Benefits of Using Self Leveling Floor Compound on Wood Subfloor

There are several advantages to using self-leveling floor compounds on wood subfloors:

Leveling: Self-leveling compounds flow and self-distribute, effectively leveling uneven subfloors, filling in dips and smoothing out high spots.
Moisture Resistance: Cementitious self-leveling compounds provide moisture resistance, protecting the subfloor from potential moisture damage.
Crack Repair: Self-leveling compounds can fill in cracks and gaps in the subfloor, creating a more stable and durable base.
Sound Insulation: Self-leveling compounds can improve sound insulation by filling in air pockets and reducing noise transmission.

Types of Self Leveling Floor Compounds

There are two main types of self-leveling floor compounds for wood subfloors:

Cementitious Self-Leveling Compounds: These compounds are made with cement and provide excellent leveling, moisture resistance, and strength.
Gypsum-Based Self-Leveling Compounds: These compounds are made with gypsum and are suitable for areas where moisture resistance is not a major concern.

Factors to Consider Before Using Self Leveling Floor Compound

Before using self-leveling floor compound, certain factors should be considered:

Subfloor Preparation: Wood subfloors must be clean, dry, and structurally sound. Any loose nails, splinters, or debris should be removed.
Moisture Content: Wood subfloors should have a moisture content below 15% before applying self-leveling compound.
Floor Height: Self-leveling compounds add height to the floor, so it's important to ensure that doorways, baseboards, and other obstacles will be clear after the installation.
Drying Time: Self-leveling compounds typically require several hours to dry and cure, so it's important to schedule the installation accordingly.

Installation Procedure

Installing self-leveling floor compound on a wood subfloor involves the following steps:

Prepare the Subfloor: Clean, dry, and repair any damaged areas of the subfloor.
Mix the Compound: Mix the self-leveling compound according to the manufacturer's instructions.
Pour the Compound: Slowly pour the mixed compound onto the subfloor, starting in one corner and working your way towards the opposite corner.
Spread the Compound: Use a trowel or screed to spread and level the compound evenly.
Spike and Roll: Remove entrapped air from the compound by spiking it with a spiked roller.
Allow to Cure: Let the self-leveling compound dry and cure for the time specified by the manufacturer.

Conclusion

Self-leveling floor compound can be a valuable tool for leveling uneven wood subfloors, providing a smooth and stable base for various flooring materials. By considering the factors and following the proper installation procedure, you can achieve a professional-looking and durable floor.
