Polyurethane plywood is a popular choice of finish that can be used to protect wood from moisture, scuffing and general wear and tear. It also offers a tough, durable clear coating that can help to enhance the color and grain of the wood. The type of polyurethane that you choose will depend on a number of factors, including the intended use of your plywood and your personal preference.Read more :polyurethaneroofcoating.co.uk

Oil based polyurethane is ideal for exterior projects, as it will provide better protection from water and other weather elements. It dries quickly and provides a glossy, smooth surface. However, it does emit more volatile organic compounds (VOC) than its water-based counterpart, so you’ll need to take extra precautions to shield your workspace from the fumes.

Protecting Plywood Surfaces with Polyurethane: Best Practices

Water based polyurethane can be a good option for interior projects, as it dries more quickly and provides a glossier finish. It doesn’t emit as many VOCs as oil-based polyurethane, so it’s generally considered to be safer for indoor use. However, water-based polyurethane can be prone to “sheeting,” so you may need to apply more coats than oil based polyurethane to achieve a smooth, finished look.

Whether you choose oil or water based, it’s important to sand between coats. This will help to create a smooth, even surface and make sure that the polyurethane adheres to the wood properly. Once you’ve sanded the surface, wipe it down with a damp cloth to remove any residue. Then let the surface dry completely.
