Acrylic Vs. Polyurethane Flooring

Polyurethane

• A polyurethane finish, also called urethane varnish, consists of urethane polymers that bond together to protect wood surfaces like furniture and, of course, floors. Polyurethane finishes are fast-drying, highly durable, and heat-resistant. Polyurethane finishes can also protect wood floors from moisture penetration and, therefore, prevent mold growth. Polyurethane finishes are among the most commonly sold wood floor finishes, and they come in both oil-based and water-based varieties.

Water-Based vs. Oil-Based

• When choosing a polyurethane finish, you must first consider the floor itself. Some wood floor manufacturers advise against using oil-based finishes, even though oil-based finishes are among the most protective and easiest to apply. Additionally, oil-based polyurethane may lighten the wood over time, while water-based polyurethane will retain the natural color of the wood. Also, oil-based finishes dry much more slowly, and cost more money per gallon than their water-based alternatives.

Acrylic

• Unlike polyurethane, acrylic finishes are always water-based. In fact, some water-based polyurethane finishes actually contain a combination of urethane and acrylic. Some wood floors are treated with acrylic resins during the manufacturing process, and this acrylic impregnation provides a natural shine and heightened durability. By contrast, commercial acrylic finishes, sold in large cans, do not penetrate the wood floor, but serve as a transparent topcoat, and do not boast the same level of durability.

Choosing a Finish

• If your wood floor manufacturer advises against using oil-based finishes, always stick with acrylic. For the utmost durability, choose polyurethane over acrylic, or invest in an acrylic-impregnated wood floor. If you plan to apply the finish yourself, note that fast-drying finishes like water-based polyurethane are much easier to apply. Lastly, consider whether or not you want to retain the exact color of your wood. If you do want to retain the original color, use acrylic or water-based polyurethane.
