Choosing The Right Compound
Choosing the right self-leveling compound is key for wood floors. It ensures a smooth, even surface. The right product prevents damage and improves floor durability. Not all compounds work well on wood. Some may cause warping or poor adhesion. Understanding types and factors helps select the best compound.
Types Of Self-leveling Compounds
There are several types of self-leveling compounds. Cement-based compounds are common and strong. They work well for most floors but need a moisture barrier. Gypsum-based compounds dry faster and are smoother. These are good for indoor use. Polymer-modified compounds offer extra flexibility. They resist cracks and bond better to wood.
Factors To Consider For Wood Floors
Wood floors need a compound that is flexible. Wood expands and contracts with temperature and moisture. Choose a compound that can handle movement. Check drying time. Faster drying saves time but may limit working time. Look for low shrinkage to avoid cracks. A product with good adhesion to wood is vital.
Recommended Brands
Several brands make reliable self-leveling compounds for wood. Ardex offers high-quality polymer-modified options. Mapei produces fast-drying compounds with good flexibility. Custom Building Products provides user-friendly mixes for wood floors. Always read product instructions to ensure compatibility with wood.

Preparing Wood Floors
Preparing wood floors for self-leveling compound is a key step for a smooth finish. Proper preparation ensures strong adhesion and a flat surface. It reduces the risk of cracks and bubbles in the compound. Take time to prepare the floor well before applying the compound.
Cleaning And Repairing
Start by cleaning the wood floor thoroughly. Remove dust, dirt, and grease using a broom or vacuum. Use a damp cloth for sticky spots but avoid soaking the wood. Check the floor for loose boards or nails and fix them. Fill any deep cracks or holes with wood filler. Let the filler dry completely before moving on.
Moisture Testing
Test the wood for moisture content. Use a moisture meter for accurate readings. Wood should have less than 12% moisture before applying the compound. High moisture can cause the compound to fail or peel. Allow the wood to dry fully if the moisture is too high. This step prevents long-term damage and ensures proper bonding.
Priming The Surface
Apply a primer designed for wood floors before the compound. Primer helps the compound stick better and prevents bubbles. Use a brush or roller to spread the primer evenly. Let the primer dry according to the product instructions. Proper priming sets the stage for a strong, level floor.
Mixing The Compound
Mixing self-leveling compound correctly is key for a smooth finish on wood floors. The right consistency makes application easier and ensures the compound spreads evenly. Poor mixing can cause lumps or weak spots, leading to cracks or uneven surfaces. Understanding the tools and techniques helps achieve the best results.
Tools Needed
Use a clean bucket to mix the compound. A drill with a paddle mixer attachment is best for thorough blending. A measuring cup or scale helps add the right water amount. A trowel or spreader assists with smoothing out the compound after mixing. Have a stopwatch or timer to track mixing time.
Proper Mixing Techniques
Start by adding water to the bucket first. Then slowly add the powder while mixing. Use the drill on low speed to avoid air bubbles. Mix for about two to three minutes until smooth. Stop and scrape the sides to mix all powder. Avoid over-mixing to keep the compound stable.
Avoiding Common Mistakes
Do not add too much water; thin compound weakens the floor. Avoid lumps by mixing slowly and steadily. Do not mix too long; it causes early drying. Clean tools before mixing to prevent contamination. Use the compound quickly after mixing for best flow.

Application Process
Applying self-leveling compound on wood floors requires careful steps. This process ensures a smooth, even surface ready for flooring installation. Follow simple steps to get the best results.
Pouring And Spreading
Start by mixing the compound according to the instructions. Pour it slowly onto the wood floor in small sections. Use a trowel or spreader to move the compound evenly. Work quickly to avoid thick spots or air bubbles. The compound should flow and settle on its own.
Working Time And Setting
The compound has limited working time before it starts to harden. Begin spreading right after mixing. Avoid walking on the surface during this time. Let the compound set fully before the next step. Usually, setting takes a few hours but check the product label.
Handling Edges And Corners
Edges and corners need extra attention. Use a small brush or tool to push the compound into tight spaces. Avoid leaving gaps or uneven areas. Smooth out edges carefully for a consistent finish. Proper handling prevents cracks and lifts later.
Drying And Curing
Drying and curing are key steps after applying self-leveling compound on wood floors. Proper drying ensures the compound hardens well and stays strong. Curing lets the material reach full durability and prevents cracks or damage later. Understanding how drying and curing work helps you get the best results.
Optimal Conditions
Keep the room temperature between 65°F and 75°F. Avoid cold or hot spots that slow drying. Maintain good air flow but no strong drafts. High humidity can delay drying. Use a dehumidifier if needed. These conditions help the compound dry evenly.
Drying Timeframe
Drying usually takes 24 to 48 hours. Thin layers may dry faster. Thick layers need more time. Check the product label for exact times. Avoid walking on the floor until it feels firm. Patience here prevents damage and uneven surfaces.
Signs Of Proper Cure
The surface feels hard and smooth to touch. No soft spots or powdery areas remain. The color is uniform without wet patches. The compound bonds well to the wood. Proper cure means the floor is ready for sanding or finishing.

Finishing Touches
Finishing touches are key after applying self-leveling compound on wood floors. They help create a smooth, strong base ready for any floor covering. Careful preparation ensures your floor looks great and lasts longer.
Sanding And Smoothing
After the compound dries, sanding is essential. It removes bumps and rough spots. Use fine-grit sandpaper for a smooth finish. Sand lightly to avoid damaging the surface. Clean the dust well before the next step.
Applying Floor Coverings
Choose floor coverings that suit your style and needs. Vinyl, laminate, or hardwood work well over self-leveled floors. Follow manufacturer instructions for the best results. Proper installation prevents future issues like lifting or cracking.
Maintenance Tips
Keep your floor clean to extend its life. Sweep or vacuum regularly to remove dirt and grit. Avoid harsh chemicals that might damage the surface. Use felt pads under furniture to prevent scratches. Check for cracks or damage and repair quickly.
Troubleshooting Issues
Troubles with self-leveling compound on wood floors can slow down your project. Knowing how to fix common problems saves time and effort. Problems like cracking, peeling, uneven surfaces, and poor adhesion happen often. Understanding causes helps find the right solution fast.
Cracking And Peeling
Cracks appear when the compound dries too fast or too slow. Wood movement can cause peeling or cracks as well. Poor mixing or wrong compound type also leads to these issues. Fix cracks by sanding the area smooth. Apply a thin new layer after cleaning the surface.
Uneven Surfaces
Uneven surfaces occur if the compound is poured unevenly. Too thick or thin layers cause bumps or dips. The floor must be clean and dry before applying. Use a trowel or spreader to smooth the compound quickly. Wait for full drying before adding more layers.
Adhesion Problems
Poor adhesion happens when the wood is dirty or oily. Moisture in the wood also stops the compound from sticking. Always clean and prime the floor first. Check wood moisture levels before starting. Using the right primer improves bond and stops lifting or bubbling.
