Polyurethane Over Paint - The Benefits

What Is Polyurethane?

Just like every other varnish, polyurethane is a varnish that can be applied on surfaces like metal or wood to make the surface clear, hard and shiny.

Polyurethane is a good varnish because it protects the surface of wooden objects from scratches and it makes cleaning a lot easier. Applying polyurethane over paint is an excellent idea since it gives a lovely finish to cabinets and other surfaces.

There are two types of polyurethane: water-based and oil-based. Both are ideal for using over latex paint, but a lot of people prefer water-based polyurethane because it can stand the test of time without any issue.

How To Apply

Before you start applying polyurethane over paint, you should make sure the object you want to paint is completely dust, grease and dirt free. Sand it, vacuum it, clean it with a lint-free cloth, and optionally apply a sealer.

Applying polyurethane is easy but patience is required because each coat must be left to dry properly.

Brush-on and wipe-on are the types of polyurethane that you can get. Brush-on products are to be brushed on while wipe-on products are to be wiped on.

Two or three thick coats are required when using a brush-on, and each coat must dry overnight. A wipe-on needs just four or five coats and each coat has to dry for 3 hours.

Brush-on varnish gives a solid look, while a wipe-on varnish gives a soft look when applied.

Here Are Some Tips

Keeping polyurethane bubble-free is important. You can do that by stirring with a paint stick instead of shaking.

Ducts and vents should be covered when a water-based polyurethane is used in order to minimize dust. If an oil-based polyurethane is in use, then proper vacuuming is required.

Before polyurethane dries, always remember to run the brush over it lightly to smooth out any air bubbles. Remember to use a bristle brush, not a foam brush.

Each coat should be sanded before the next is applied. Dust should be vacuumed up after sanding.

That's how it works. Good luck with your polyurethane project!
