Do I need a primer? What kind?

Posted by jack on July 31, 2008, 12:34 pm

I have a cabinet made of varnished plywood. I am adding oak molding and
then painting it all.

Do I need to use a primer? If so, what kind?
Do I have to sand the varnished plywood first?

Thanks

You will need to wash the varnished plywood thoroughly
as well as sand it to make a "tooth" so that the paint will
adhere.

The unstated problem here is how the varnish will react
to the paint. If you are lucky there may be no reaction
i.e. the varnish will serve as a primer. If they are chemically
incompatible you will need to remove the varnish.

If you're going to paint it anyway, why bother with the expense of oak
molding? Pine, MDF, or plastic would work just fine.

Depends. Do you want the paint to stick?

I'd use an oil-based primer.

It would sure help. Go to a real paint store (not the paint department at Home
Depot or Lowe's), tell them what you want to do, and ask them for
recommendations.

Go to a paint store and ask them? Than's your advice? Why did you even
respond to his post if that's the best you can do. Either put up or shut
up.

Welcome to the killfile.
