Dents and gouges are easily
repaired using joint compound or other patching material. Small gouges
can usually be repaired without the use of reinforcing mesh tape. Simply
applying one or more coats of joint compound will fill and hide most
For dents, simply apply patching compound with a putty
knife to create a smooth, even patch. Allow the patch to dry. Because
the material may shrink as it dries, additional applications may be necessary
to completely hide the damage.
If you apply too much and fill in the surrounding texture, use a damp rag to wipe away the excess. You may wipe away the patch material too, but it is easy to just reapply another coat.
After the compound has dried for at least a couples hours, lightly sand
it smooth. Wipe away any dust and apply another coat of joint compound
After the joint compound has thoroughly
dried, it can be sanded and painted.
