Repairing a damaged wood floor is important to both the function and appearance of your home. Damaged floors reduce the value of the home, look unattractive, make loud noises when the floor is walked upon and present trip hazards. Making sure new boards match the old can be tough, so harvest identical floor boards from the back of a nearby closet if you cannot find an exact match at your local home store.
Small holes in floorboard can often be filled with wood putty. Lightly sand after the putty has dried and color to match the rest of the floor. A rotary tool with a sanding band makes a great spot sander for these repairs. Spray a small area with a floor finish and sealer that is compatible with your existing finish. Test this at a discreet location because the old finish may not work with the new finish. Try to use the same products on the entire floor to prevent finish problems.
Fill small floorboard gaps with strips of flooring cut and fitted to fill the gap. Cutting, sanding and wood shaping accessories on a rotary tool work well for this task. Look for floorboards in the same type as your existing floor. Cut the floorboard after measuring for the exact dimensions. Test fit the piece until it sits smoothly with the rest of the flooring. Attach the new piece with floorboard putty. Wipe off any excess and fill the gaps on all sides of the repair.
Drill holes at both ends of each board that you need to take out. Cut a line across the end of each board. Make a cut down the center of the board. This will reduce the stresses on the sides of the board and make it easier to remove the board pieces. Remove all of the boards in one area that need to be replaced. Cut off the bottom of the groove of the last board. Install the majority of the boards with nails through the tongue. The last board will require a recessed nail through the floor surface. Fill the nail holes with wood putty.
Matching The Finish
Blend stains to match an old finish. A disposable plastic container can be used to mix together several colors of stain, and achieve the desired results. Make sure to test your new stains on a sample board of the same type as the repair boards. Keep testing until you achieve a color that looks close to the old flooring. Simply stain and finish the flooring with the same products used on the rest of the floor.
