I built a bed for my son out of Pine (from plans on the internet.) I am going to paint it white. What kinds of preparation do I need to do to the wood, especially considering the 4 posts are from pressure-treated pine -- the kind of wood you use on a deck that you buy from Home Depot that probably is treated to keep away insects and repel moisture. Sanding - how fine? 220 grit? Anything after sanding like a sealant? |

I would not ever use pressure-treated wood for any internal application - framing or furniture. Go buy non-pressure treated 4x4s, or sister together two 2x4s to build 4x4s. Otherwise, I sand pine down to 180 grit, prime, and paint. |

For outdoor use, I've always heard that you have to let treated wood dry for a year before painting, but the exact time may vary based on how dry the local climate is. But Adam Musch is right -- pressure treated is treated with poison -- arsenic, copper, cyanide (until about 2003, when most companies started using less poisonous chemicals). You don't want to be using it inside, and sanding's a bad idea unless you're vaccuuming up the dust and wearing as mask. |

I would never use the old CCA treated wood in an exposed indoor area, especially for a toddler bed. However, contrary to what others have said, the new ACQ treated wood should be perfectly safe. It does not contain aresenic or cyanide. Also, ACQ wood has a much higher copper content than the old CCA wood did (to make up for not having the arsenic). Because of this, it is much more corrosive to fasteners. Make sure you use either hot-dipped galvanized or stainless steel fasteners to ensure that they don't corrode and fail on you. |
