Polyurethane plywood is a type of wood finish that can be used to protect and enhance the look of your project. It forms a clear, hard film that helps to protect wood from moisture and abrasions. The durability of this type of finish makes it a popular choice for projects such as cabinets and furniture. Polyurethane is available in both oil and water based varieties, with each offering unique benefits for your woodworking project.Source :https://polyurethaneroofcoating.co.uk

Typically, oil-based polyurethane offers greater durability than its water-based counterpart. This product also dries more slowly, giving you more time to perfect your project between coats. It is usually cleaner to work with than its water-based cousin, but it does release higher levels of VOCs (volatile organic compounds).

Water-based polyurethane, on the other hand, provides a slightly less durable finish, although it still offers good protection for your wood project. It also dries much faster than its oil-based counterpart and produces fewer VOCs, making it easier to work with. However, it is important to note that water-based polyurethane can yellow over time and may require more reapplications than its oil-based counterpart.
