How To Stain And Varnish Wood

Can you stain and then varnish wood?

For a very durable finish and one that needs to be very tough, say on a kitchen table, coffee table or end table etc, 2 to 3 coats of varnish should be enough on the top, with 1 to 2 coats on the legs/base. For chairs, benches, chests and other such pieces, 1 to 2 coats should do the trick.

How long should stain sit before wiping off?

Can you apply varnish with a rag?

You really can use just about anything to apply varnish and other finishes to a surface, even a rag or the flat part of your hand. It’s what you do after the varnish has dried that makes the difference in the end. But in reality, any varnish can be used for a wiped finish, even polyurethanes.

Should you sand after varnish?

Should you sand between coats of varnish?

Sanding between coats of varnish is important because it achieves two things: First, it knocks down the “high spots” and second, but more importantly, it provides a tooth for the next coat to adhere to. Otherwise, the subsequent coats can delaminate and lift off in large sheets.

Will 2 coats of stain make it darker?

Apply a second coat of stain after the first has dried fully. This will usually produce a darker coloring, but it adds a step to the process and slows production. Leave a dampness of stain on the wood that dries to a darker coloring.
