The Importance of Sealing a Concrete Floor
Think of a concrete floor sealer as a protective layer that will improve its appearance and durability. Much like applying a stain guard to a new sofa or waxing your prized automobile, sealing a concrete floor is important for protecting your investment. Stain protection is the main reason for sealing concrete floors, especially in areas of your home or business where food and drink will be consumed. Pets may also casue damage to a concrete floor that can be prevented with a properly applied sealer. New concrete floors should be sealed upon completion, while existing concrete floors should be sealed every 1-2 years based on wear-and-tear.
Sealing concrete will lock down the colors and provide a high gloss. Depending on your desired sheen, floor sealers are available in a variety of gloss levels, ranging from matte to high gloss. Additionally, specialty sealers tinted for color enhancement can be used. Finally, if your concrete floors are in an area of your home where moisture is common (kitchen, bathroom, entryway) a sealer with a slip-resistant additive is a good idea.
Typically, film-forming sealers, which include acrylics, polyurethanes and epoxies, are used on interior concrete. Acrylics are softer, require more maintenance and may show scuffs and shoe marks. Regular waxing may help prevent these issues. When selecting a sealer for your floor, consider the decorative treatment (staining, overlay, polishing, etc.) and check with the manufacturer for compatibility to avoid blistering, bubbling or bleeding. Also consider whether the sealer is safe to use indoors. Some sealers release harmful fumes and contain volatile VOCs.
