Ever wonder what wood is the best to burn as firewood? Oak is an American favorite, other hardwoods are also a good choice. You can burn other softer wood also, as long as it is split and dried long enough. It's much more important to burn dry wood than to worry about what kind of wood it is.
If you’re painting over an old semi-gloss paint, check to see if it has become hard and brittle. Try to pick off a piece from an obscure area with your fingernail. If it chips, it probably needs a light sanding to improve the “tooth” for a new coat of paint.
