How to Fix Water Damage on a Hardwood Floor

Many homeowners experience water damage every year due to a number of different circumstances. When you have a hardwood floor, you know that it does not handle water problems very well. You have a few different options when it comes to repairing water damage to hardwood flooring. Here are a few steps that you can take to repair a hardwood floor that was damaged. 

Step 1 - Removing Stains

If the water just managed to stain the hardwood, then you could be able to remove the stain without a lot of other work. For this process, you can sand down the boards that are affected and then use oxalic acid crystals to remove the water stain. At that point, you can then reapply the stain and coat it with polyurethane sealer. However, many times, it will require more work than this. If your boards are warped from the water, you will have to replace them and sand the entire area and refinish it to match.

Step 2 - Remove the Damaged Boards

If you have boards that are warped, you will need to remove them from the floor. If they are bent upwards, there is a good chance that they are no longer attached to the floor. You can use a saw to cut down into the floor in the affected area. Use the pry bar to pull upwards on the boards that are damaged. Pull them up off of the floor. If you do not have experience in lacing boards back into the middle of the floor, you may want to take up all the way over to a wall.

Step 3 - Install New Boards

Once you have cleared out the damaged boards, you will need to install new hardwood in its place. Make sure that you get the same species and grade that you have on the floor currently. You will also want to allow the new wood to acclimate to the new environment before you install. This will ensure that it fits together well with the existing hardwood. Fit a new board into an adjacent board by sliding the groove onto the tongue of another board. Shoot some staples down diagonally through the tongue of the board. Continue installing boards until the area is filled. 

Step 4 - Sand the Floor

Once the wood is in place, you need to sand the entire floor with a sander. Take off the layer of finish and stain and get down to where you are working with raw wood again on everything. 

Step 5 - Stain the Floor

You will then need to stain the floor. Stain the entire floor so it will be consistent throughout. Allow the stain to dry thoroughly before proceeding.

Step 6 - Finish the Floor

Once you have stained the floor, you will need to put two coats of polyurethane finish on it. Apply the first coat and let it dry. Then apply a second coat and allow it to dry before using the floor.
