How to Seal Wood Parquet

Updated April 17, 2017

Parquet adds a level of visual interest to your floors that is unavailable through other types of flooring. If your parquet floors are a little dated or damaged and need to be repaired, they will have to be sealed. Sealant makes wood waterproof and prevents scratches, dirt and stains from damaging the wood. Hiring someone to seal your parquet floors is possible; however, you can easily seal your floors yourself, which will save you money and time. Gather your materials and get started on sealing your wood parquet floors.

Remove all furniture from the room. When moving, avoid dragging the furniture, which can scratch the floors. Vacuum the floors to remove all dust, dirt and pet dander so that the floors are clean.

Sand the floor with the orbital sander to remove the top layer of finish. The entire floor must be sanded, or else the sealant will be uneven throughout the room. Start sanding in a corner and slowly work your way outward to ensure that you sand every inch of the floor. Work slowly to avoid damaging your floors. When finished, vacuum the floors again to remove all of the dust. Sealant will not adhere to a dusty floor, so complete removal of the dust is vital.

Fill a bucket with water. Dip the rag into the water and wring it out. Thoroughly wipe off the floor with the damp rag to remove any lingering dust and sandpaper grit. Allow the floor to dry completely.

Apply the sealant to the parquet floors with the lambswool applicator. Pour the sealant on the floor and spread it evenly with the applicator. Avoid spreading it too quickly, which will cause bubbles to form on the floor. If you used water-based polyurethane, let the floors dry for an hour before applying the second coat. For oil-based polyurethane, the floors will need to dry for 12 hours.

Add the second coat of sealant and allow it to dry completely. Wait one day before walking on the newly sealed floors and moving furniture into the room.
