Protect For Long Lasting Beauty
While wood stains add color and bring out the beauty of the wood, clear finishes protect the wood and enhance its beauty. Whether you choose to stain your wood project or not, it is important that you protect the wood with a clear finish, such as polyurethane.
Most clear finishes are available in gloss, semi-gloss and satin sheens. Choosing a sheen is a matter of personal preference.
The gloss level will affect the appearance of your piece, but not its durability.
Clear finishes, sometimes called “topcoats” will protect your project against damage from water, household chemicals, and everyday wear. And the beautiful finish will make your wood come alive!
Choosing a Clear Finish
Choosing the best clear finish for your project will depend on a few key factors.
- Project type: A project that will see heavy use, such as a tabletop, requires more protection than a project that will be subjected to less wear and tear. Be sure to choose a clear protective finish that is right for your project.
- Exposure to sunlight and humidity: Doors, windows, bathroom cabinets, kitchen countertops and outdoor furniture can all be exposed to sunlight, temperature changes and humidity. For these conditions, you need to protect your project with a finish that has ultraviolet absorbers and special oils that expand and contract with temperature changes.
- Crystal clear or amber tone: Many clear finishes add a rich, warm, amber tone to the wood. Others remain crystal clear. You can choose whichever look you prefer for your project. However, if your project is a light color—whether stained or unfinished wood—it is best to protect it with a finish that remains crystal clear.
- Ease of application: Some Minwax® clear finishes can be easily applied with a cloth—no need to worry about drips or brush marks. Some dry very quickly and can be cleaned up with soap and water, while others require mineral spirits.
- Note for hardwood floors: Some general-purpose clear protective finishes can be used on floors. Minwax® also offers topcoats that are specially formulated for hardwood floors. They have application benefits that make them ideal for large surface applications.
