Can You Stain and Varnish Primed Wood?
A commercial paint stripper and a rag are all you need to remove the primer before staining. Of course, you should always work in a well-ventilated area while wearing protective goggles and gloves when using paint strippers because they give off toxic fumes and can irritate your skin and eyes. Spread the paint thinner over the surface of the wood, and allow it to sit for about 10 to 15 minutes. Scrape the primer off the wood, using a plastic putty knife.
