Can you varnish over oil paint?

Answer 1

Any paint will adhere to lead based paint and seal it. Latex is the easiest. The lead will not bleed through and is not harmful as long as it is not flaking off. It is only harmful if a child chews on it and swallows it.

Answer 2

If the lead-based paint is sound and is not peeling or cracking, you can paint directly over it without the use of a primer because lead-based paint in itself is a form of primer.

That said, if children or pregnant women are using the painted area, it is safer to totally strip off all the old, lead paint down to the bare wood making sure that you use lead-safe work practices. (See the Sources and related links section, below, for more information)

An environmentally safe and clean method is to use Speedheater Infrared Paint Remover which doesn't vaporize the lead in the paint and create clumps of heated, soft paint for easy containment and disposal. Then you can either stain, varnish or prime and repaint.

Answer 3

NO! Latex paint will seal in the oil-based varnish and will lead to cracking and peeling, as well as not adhering properly, since any oil-based product never fully dries. It's ok if done the other way around though.

Answer 4

Indeed you can. As an example Most vehicles have base coat and lacquer finish these days. Adding varnish over a painted surface will preserve the paint.

Answer 5

Oil based paint can be used over wood varnish. I wouldn't recommend using a latex.

Answer 6

If it's enamel based, not latex based.

Answer 7

Yes, you can.

Answer 8
