A finish brush will apply a thinner coat than a paint brush, which would deliver globs of product. The thinner the layer, the less chance you will have of creating bubbles. Before you brush on the polyurethane, soak the brush in mineral spirits. You can also use water. Gently brush it across a piece of newspaper to dry it out before use. Thinning the polyurethane can also help. Use mineral spirits for oil-based polyurethane and water for water-based products.
Use a ratio of three parts polyurethane to one part of your thinning material. Gently stir in the solvent; never shake the products to mix, because shaking will create bubbles even before you start. When you start applying the polyurethane, practice applying thin layers in gentle strokes.
If you work in much higher temperatures, the layers will simply dry quicker, especially with water-based polyurethane. Applying the product requires a combination of ability and knowledge. As with any home improvement project, careful selection and proper preparation will affect your results.

Learn which types of flooring will increase the value of your home. What Materials Do You Need? Overall, polyurethane is generally used for indoor household projects like bookshelves and desks, while varnish is popular for outdoor surfaces such as a deck. Both offer durability, varied color options, and protection against elements. However, when applying a finish to your interior hardwood floor, polyurethane is the better option. While varnish provides value in its protection against ultraviolet light and natural durability, it is specifically designed for outdoor surfaces.
Polyurethane on the other hand, offers durability and flexibility for interior projects. If your floor will be subject to heavy traffic, an oil-based poly is the more durable choice.

Things to Consider Before you start evaluating your options, you need to know a few things about your project to get the best finish: Durability : How long do you want your flooring to last before you need to apply another coat? When assessing your options, keep in mind what your flooring will be primarily used for. From this point forward, keep your feet clean when walking on the sanded floor by using shoe covers or socks.
Apply painter's tape to walls, trim, and other large items that cannot be removed. Apply the tape tightly to prevent the polyurethane from seeping below the tape. Stir the polyurethane gently.
Do not shake. Dip the brush in the finish and apply the finish to the edges and corners, up to the painter's tape. Pour the polyurethane finish into a lined paint tray. Fit the applicator pad on the applicator. Dip the applicator in the polyurethane.
Brush the polyurethane onto the floor in a W-pattern until complete. Make sure that you are using only an applicator intended for floor finishes. Cotton and other types of applicators may leave lint behind, which can become sealed under the finish. Let the finish dry until it is dry to the touch and hard. If the previous coat is more than three days old, lightly sand the floor with grit sandpaper and thoroughly clean.
Recoat the flooring , repeating the previous steps. Be sure to cut in the finish before applying the finish to the main section of the floor. Actively scan device characteristics for identification. Use precise geolocation data. Select personalised content. Create a personalised content profile. Measure ad performance. These are just a few of the qualities that make water-based polyurethane one of the most popular hardwood floor finishes for the home.
Water-based polyurethane also scores high in the environmentally friendly category, releasing far fewer volatile organic compounds VOCs than many of the other options. It has little odor during application, which is a big benefit if you plan on finishing the floors yourself.
Oil-based polyurethane consists of linseed oil, synthetic resins, and plasticizers. Its strength and durability make it a popular finish for commercial properties, but many homeowners like to use it in high traffic areas inside the house, as well.
Generally, it takes eight to 10 hours for each coat to dry two to three coats total is the usual recommendation. Originally created for use in bowling alleys, moisture-cure urethane is extremely tough and durable after it dries to a very high shine. It resists moisture, scratches, stains, and general wear.
Its difficult application makes it less of an option for a do-it-yourselfer, though. Plus, the very high level of VOCs it releases can linger in the air for weeks, so all household members will need to relocate for as long as two weeks after application. An even application of this fickle finish requires a quick hand and an experienced touch.
