I am redoing a bathroom and want to paint the existing wood medicine chest and vanity bottom white. (Never thought I would paint over nice wood, but I want to give it a fresh look).

Anyway, my question is.....What exactly do I have to do before I paint? Do I have to sand it lightly and then prime? OR can I just go ahead and prime and paint??

Thanks for any help!

Yes you want to sand before you paint and then you will want to wash the cabinet with ammonia and water to be sure it is clean.

Then you will want to prime it with Zinsser BIN and finish with either an acrylic enamel or oil based enamel. The oil based is a harder finish but it will yellow over time an the acrylic will not. I have had good results with acrylic.

If you don't like using ammonia(I prefer not to) you can buy TSP(tri-sodium phosphate) It only costs a few dollars and won't make you go running for an open window! Sanding is a good idea because it dulls the finish allowing the primer to adhere better. I am lazy and prefer to get acrylic primers which allow me to NOT sand. I guess it really isn't sanding though. It is more of a scuffing which only takes about one minute if done right.

Yes TSP is a great cleaner but the reason I don't recomend it is that you have to be sure to rinse it off well as it will leave a residue that will bleed through the paint and cause adhesion problems as well.

No matter what the paint companies say you should sand before you paint anything that is slick and glossy. Also there are acrylic primers and there are acrylic bonding primers and there is a big difference between the two.
