What is water based polyurethane?
Water-based polyurethane is a finish that offers a smooth and lustrous look in a variety of sheens (or levels of shine.) Polyurethane is a plastic material or polymer that is used in many types of applications, from insulation and foam to plastic wheels and protective coatings. When used in a flooring finish, it’s applied as a liquid that dries and hardens to form a protective, moisture-resistant top coating on a hardwood floor. For years, oil-based polyurethane was the standard in finishes for hardwood floors, but water-based polyurethane is replacing it as one of the most popular types of finish for several reasons.
How many coats of polyurethane for prefinished wood?
On-site finishes typically involve three applications of finish, while a prefinished floor may have 3-5 coats or even more. As a result, a prefinished floor is even more protected from deeper scratches as the thick layer stops heavy traffic from quickly wearing back to the wood or the stain color. Most factory-applied polyurethane finishes are more durable than site-applied finishes as additional additives can be used to enhance scratch resistance. It’s important to check with each manufacturer as to what additives are being used, however. High amounts of chemicals like aluminum oxide, for example, can result in a hazy, plastic-looking floor if overused. At Carlisle, we use a small amount of aluminum oxide that helps improve scratch resistance without sacrificing the clarity and richness of the finish that is so desirable when working with exceptional wood.
How to fix scratches on polyurethane?
If you have chosen a finish with minimal additives, you can typically touch up a small scratch by buffing it and applying a small amount of finish. This will fill in the scratch and return some sheen to the area to make it less visible. When you have wear over a larger area, it’s best to lightly buff the floor and apply a new topcoat of polyurethane to the entire room. At Carlisle, we offer a “dustless recoat system” that allows the new topcoat of finish to adhere without having to buff the floor, which can create excessive dust.
