Hardwood flooring is beautiful, timeless and improves the value of your property. Wood may be amore expensive option, but it can be awise long-term investment if properly maintained. You can refinish ahardwood floor and rejuvenate its appearance as soon as it begins to show wear andtear.
The process of preparing, treating and finishing floors is complex, and every choice you make can have asignificant influence on the final product. This article will review and discuss the characteristics of polyurethane and other wood stains so that you can choose the best option for yourneeds.
What is Polyurethane?
Polyurethane is apolymer. Polyurethanes are created by mixing two types of chemical compounds, known as Polyols and Isocyanates, with other additives to create achemical reaction. The basic material has several distinct, well-tolerated variations that can be customized and offered in liquid, foam or solid, each with its own benefits and drawbacks.
What is Polyurethane UsedFor?
Polyurethane is often used as acoating to protect surfaces from wear and tear. It can be made clear or colored and comes in both glossy and matte finishes. Polyurethane is durable and water-resistant, making it apopular choice for protecting wood floors.
Understanding Wood Staining and the Component Materials
Many of today’s flooring options are made from composite materials with aprefinished wood surface layer. If you want natural wood flooring, you need to understand how polyurethane and stains are absorbed by the different types ofwood.
Wood
Wood is divided into two broad categories: hardwood and softwood. However, the names don’t always refer to its actual hardness or softness.
Because of the way they develop, hardwoods are typically heavier than softwoods. Denser woods are better suited for flooring, building, decks and high-end furniture because of their higher density. In addition, hardwoods have amore solid cellular structure so liquid stains have aharder time getting inside the wood. If you don’t sand the wood before staining it, it won’t absorb the stain properly, which may lead to less stain absorption.
Softwoods have an open-cell structure. This allows them to soak up alarge amount of stain, which may lead to undesirable effects.
Wood Stain (Optional)
Stains, as the name implies, are colorants used to alter the wood’s hue or tone. Stains are not the final coat — aprotective coating, such as polyurethane, is required to safeguard the wood. Stains reveal the grain, add hues to the natural wood or can even change them completely. The stain is poured as aliquid, the solvent evaporates and the stain remains.
Polyurethane
Polyurethane is the final finish coat on your wood flooring. If the wood is stained, the polyurethane will protect the stained wood fibers from getting scratched and ruined. Stain by itself will not offer aton of protection because it is absorbed into the wood and is not sitting on top of it as polyurethane does. Polyurethane is available as both oil-based and water-based, as well as for interior and exterior use. The following recommendations are for interior use products.
Water-Based

ZAR® Interior Water Base Poly Crystal Clear is anon-yellowing, environmentally-safe, clear wood finish developed to preserve and enhance cabinets, furniture, shiplap paneling, woodwork and floors. You may use it on light-colored or white stains once it has dried crystal clear. ZAR Interior Water Base Poly Crystal Clear is Exotic Hardwood Approved and is suitable for use on Teak and Brazilian Walnut, as well as other similar wood species.
When used on floors, three coats are recommended, and agallon will cover 400 – 500square feet per coat. The beauty of water-based poly is that it cleans up with soap and water. Depending upon humidity levels, it dries in 30minutes and can be re-applied in twohours.
Oil-Based

ZAR Interior Oil Base Poly is an ultrafast-drying, oil-based polyurethane that dries to asmooth finish on bare wood in just two hours and leaves no brush marks. It has atough, abrasion-resistant finish and self-leveling properties, making it ideal for hardwood floors, cabinets, furniture and woodwork.
This product requires three coats for good protection, and it takes alittle longer to dry. Normal dry time is two hours, and you should wait four to six hours before applying additional coats. Oil-based also offers more coverage per gallon. You should get 500 – 600square feet of coverage per gallon, per application.
There is some confusion as to whether oil-based poly is stronger than water-based. Oil-based poly is significantly thicker and softer than acrylic whereas water-based poly, which is made of acrylic resins, is thinner but more durable. Oil-based poly might be prone to dents while water-based poly may be susceptible to surface scratching.
High Solids

ZAR Interior Oil Base Poly High Solids is ahigh-solid, oil-based paint that produces gorgeous effects in commercial and residential settings. When fully cured, it provides along-lasting, smooth finish resistant to scuffing, marring, alcohol and domestic chemicals.
The fast-drying formula permits asingle-day two-coat application. Dry time is two hours, and you can re-coat in four hours. Due to the higher solids content, the coverage is alittle less than the regular oil-based product at 400 – 500square feet per gallon.
