Polyurethane is a synthetic resin that has various forms. In liquid form, it can be used as a varnish or paint, and it can form a lovely finish on wood, latex, or acrylic surfaces. You can purchase it in oil-based, and water-based formulas. It can also be used in a rigid form and used as a sealant for multiple areas in your home. Before coating your kitchen table with polyurethane, you must ensure your table has a smooth surface. You can do this by sanding it down with sandpaper. This will remove any dirt on the table and will make the surface super smooth, ready for coating. Your table will need at least three coats, but if you’d like a glossier finish, then you can add more. There are two methods for doing this. You can spray coat it, which will give it more of a furnished look, as the spray will spread the product evenly. You must leave each layer to dry for around 3 hours, and then sand them down well. If you or anyone in your home has a breathing problem, then using spray to coat the table should be avoided. The other method you can use is a brush coating method. You must make sure to brush the polyurethane evenly throughout the table, and each coat should be left to dry for at least 2 hours. After you’ve completed the final coat, leave it to dry for 24 hours and your table should have the perfect finish!
