Repairing Sub flooring
The sub floor may be damaged beyond repair for a number of reasons. For example a water leak can wet the sub floor and can cause it to rot and delaminate. Delamination is where the individual layers of plywood separate. Individual boards cannot delaminate but can warp and this is just as bad. To replace damaged single board sub flooring, remove the damaged section and you’re able to get by with replacing a small length of board or you may need to replace the entire board.
Replacing damaged plywood sub flooring is fairly easy. You can either replace the entire piece of plywood or you can cut out s smaller section if this is all that’s needed.
Whether you need to use plywood or board installing it is the same. Set the material into position to secure it with a three-inch long drywall screws.
