9. Fill the hole – remove the masking tape and apply and spread the wood filler or spackle evenly. making sure that the gaps are filled. You can use a popsicle stick to make sure you can reach all the gaps to patch with to make sure that all will be solid and no air bubbles to be retained. Wait for the filler to dry.

Apply a single coat using your large paintbrush, in a long and smooth stroke as uniform as possible, paint over the patched hole, and let it dry thoroughly. Give the paint about an hour to dry.
