Cove base is a product that is installed along the base of an interior wall where the wall meets the floor. Cove base is primarily made of vinyl or rubber and is used to protect the base of a wall from damage and to provide a finished and more aesthetically pleasing look where it is installed. Vinyl and rubber cove base molding is often selected over traditional wood baseboards because it is typically less expensive and is generally easier to install.

Cove base is extremely versatile and is manufactured in a variety of colors to match most interior color schemes. It is sold in rolls of differing lengths and installation is quite simple. Installation usually only requires a cutting tool, adhesive and caulk. The length of cove base needed is measured and cut. A special adhesive is applied to the back of it and then it is pressed onto the wall. Once the adhesive has fully dried, caulk can be applied to the small gap between the cove base and the wall to seal the joint and improve the aesthetics.

After installation, cove base is relatively easy to maintain and can usually be cleaned with just a mild household cleanser. Repairing and/or replacing cove base is generally simple to do and is another reason why many choose to use it. If the cove base pulls away from the wall, it can usually be reinstalled relatively easily by reapplying the adhesive, pressing it against the wall, and re-caulking. If replacement is necessary, the old vinyl or rubber can usually be removed easily with small tools.

Cove base can be found in most well known home improvement stores and also through specialty retailers on the internet. Installation guidebooks are sold in stores and free video tutorials can be found on many do-it-yourself websites. The installation of cove base can also be done professionally by a carpet and flooring contractor. It's important to note that contractors will charge for the materials used and the labor required for the installation process, resulting in higher costs than a "do-it-yourself" project.
