When you construct any wood material you must apply a protective coating to ensure the wood does not rot after many years of exposure. Without the proper coating, the lifespan of the wood material will only last about 10 years before rot, and warping will occur. Building any structure is an expensive endeavor, and you must protect your investment by applying a polyurethane coating. This protective coating is stronger than most coatings on the market today, but how exactly does is hold up compared to the leading products on the market? Polyurethane coatings are much more effective than simply using paint to protect a wood surface, but it’s not appropriate for every situation. What most people don’t know is that you can use polyurethane coatings in addition to paint to make the strongest surface possible. Before you use polyurethane coating you must understand what it is, when to use it, and when to use a different product.

Polyurethane coatings are basically a liquid form of plastic that dries hard and lasts for many years. The best thing about a polyurethane coating is that it does not have any color even when it dries, except for water-based mixtures. Oil based polyurethane mixtures are stronger than water-based coatings, and hold up better under hot environments. The additional benefits of this product are that has almost no odor and is not nearly as toxic as other products on the market. This is important if you have children or pets that are sensitive to toxins in the air. Its low odor makes it so you won’t have to air out your home for several hours after applying the coating.

This product can be used directly over a paint surface without altering the pigment, and will provide a scratch resistant barrier to keep your paint looking fresh. It’s important to let the paint completely dry before applying the polyurethane coating to create a strong bond to the wall. Polyurethane mixtures are commonly used indoors for providing a coating to your walls and certain other wood surfaces. When it’s time to apply the finish, you must first prepare the surface by wiping it down with a damp rag to create a clean surface to apply the finish. You must then apply 2 coats of polyurethane, and then wait for it to dry. Once the finish dries you must closely inspect the area to ensure there aren’t drips running down the walls. Once you’ve cleaned off the drip marks you will apply a thin third coating to enhance the natural beauty of the wood grain.

Not all protective coatings can be interchangeably used for every project. Polyurethane coatings are primarily used indoors because they do not protect against ultraviolet light. For this reason, if you need to apply a finish coating to any outdoor material you should use a varnish. You should also avoid using this product one furniture because there are other products designed for this purpose. If you need to apply a finish to furniture, you must use a shellac, or varnish for best results.
