How to do varnish on plywood?

Varnishing plywood is a simple and easy way to protect the wood and provide an attractive finish. You will need to prepare the plywood surface first by sanding it smooth and wiping off any dust. Then, apply a coat of an outdoor varnish with a brush, starting with horizontal strokes and then switching to vertical strokes.

Let each coat dry thoroughly before applying subsequent coats. When you are finished, you should have a glossy, protective layer of varnish that will help protect the plywood and keep it looking great for years to come.
