Can you varnish over varnish?
Yes you can apply varnish over existing varnish. When originally applying varnish, it is done by building up coats, often at least three.

Varnish is a popular finish for raw and unfinished wooden furniture. The varnish will protect the wood from water, grease and dirt. Properly applied varnish will also give your bare wood furniture pieces a shiny, lustrous finish.
Do you need primer before varnish?
If you are wondering how many coats of primer to apply on varnished wood, usually, one layer will do the work. But when you are covering dark stain or varnish, we recommend applying two (or even more) coats of primer. In result, wood pigments won’t show through the top coat and prevent the appearance of stains.
What is the difference between polyurethane and varnish?
While polyurethane is water- or oil-based plastic resin, varnish is older and made from resins, oils, and solvents. This protection makes varnish an excellent choice for projects such as outside decks and exterior furniture. This finish gives a more tinted color when applied and requires more coats than polyurethane.
How long does varnish need to dry between coats?
It’s extremely important to be sure your first application of finish has completely dried before applying the next layer. When switching from an oil-based product to a water-based product, wait 72 hours to apply your next coat of product.
