Applying a Long?Lasting Polyurethane Coat

A long?lasting polyurethane coat helps your wood furniture resist moisture damage, protects against scratches and dents and provides a glossy finish. It’s easy to apply but requires careful attention to detail to achieve the best results.

Different quality floor sanding finish projects have unique considerations for applying and drying polyurethane. The type you choose depends on the project’s exposure to heat and the elements, as well as your preferred application method.

The choice between water-based or oil-based polyurethane depends on your preferences and the type of work you do. Water-based polyurethane is clear, low odor and quick to dry. It’s ideal for projects that don’t see a lot of direct sunlight or heat and that don’t require a stain, such as a wooden table top.

Achieving a Quality Floor Sanding Finish That Lasts Years

An oil?based polyurethane coating has a rich golden sheen and provides more abrasion resistance. It’s available in spray or brush on formats.

The application method is determined by your preference and the surface of your wood workpiece. A brush is best for flat surfaces, while a rag or aerosol spray is suitable for rounded or contoured surfaces that are more likely to create drips.

Be sure to follow the manufacturer’s instructions for your specific product. It’s also important to sand the surface between each coat. Lightly sand with 320-grit sandpaper wrapped around a block to remove any dried drips and to give the following coats something to bond to. Apply three thin coats of polyurethane for the best results.
