Repairing plaster crown moulding
Recently purchased old house; there's a section of about 5 feet of crown moulding that has been damaged by water: chipped/cracked in some parts, seems repairing was tried but job very pooly done. It's not a decorative plaster moulding, just straight indentations on top and bottom. Has anyone successfully repaired plaster crown mouldings??
Suggest using canned wood filler. Working as quickly as you can, recreate the missing portions of your molding using a painters pallet knife or any metal knife with a sharp point. Wipe and wet the knife with water to smooth and shape. Don't be afraid of rough edges, you can sand them to shape. Working in small stages is best, let each step dry and then add another layer. For intricate, decorative molding, you can use a dremel tool to "carve" shapes and designs into the dried filler. Prime, paint and enjoy!
