Whether you accidentally drilled a hole in your front door or you (regretfully) punched a hole in an interior door, you can always cover up those unsightly blemishes.
For solid core doors, you can use doweling with some carpenter’s glue and wood filler. You can also use Epoxy wood filler for larger or irregular-shaped holes along with drywall joint compound. For hollow core doors, you can use foam spray insulation with drywall joint compound. After covering the hole, priming and painting follow.
