Hardwood floors are often installed using an adhesive to keep the hardwood attached to the subfloor. Over time, the glue can loosen, resulting in loose and squeaking boards or boards that peel up from the floor. Home improvement stores sell hardwood glue injection repair kits so homeowners can repairs hardwood floors without hiring a professional. The kits generally include glue, a syringe, nails, drill bits and wooden dowels. (Refs. 1, 2.)
Purchase a glue injection kit from a home improvement store. You need a power drill and hammer to use most kits.
Locate damaged areas by tapping along the floor with your hand. If the floor sounds hollow, then the hardwood is not attached to the subfloor and you need to repair the area with a glue injection.
Use the nail punch from the kit and your hammer to make a small hole in the wood at the hollow-sounding area.
Attach the drill bit from the kit to your drill and drill it into the nail hole you created. Drill completely through the wooden plank.
Place the glue and syringe from the kit onto a piece of cardboard to catch any drips.
Draw glue into the syringe by placing the syringe into the glue and pulling the plunger toward your body.
Insert syringe into the hole and slowly depress the plunger to inject the glue beneath the wood.
Check for any hollow noises. If you hear any, continue to inject glue into the area.
Cut a wooden dowel from the kit to the fit the home, and insert it into the hole to close it. Follow manufacturer's directions for dry time.
