SunShield is specially formulated to keep teak and other tropical hardwoods from drying, cracking, and oxidizing due to exposure to the sun, temperature variations, or moisture. SunShield combines UV inhibitors with a unique blend of carnauba wax, beeswax and orange oil enhancing the natural beauty and depth of outdoor wood. It provides extra protection from the sun and weather and aids in preventing drying, cracking & deterioration of outdoor wood surfaces. Apply as needed to help preserve the original color in teak and other tropical hardwoods and help keep the wood from turning gray. Does not contain silicone or linseed oil. We tried it on an extremely weathered teak wood park bench and restored it to a beautiful luster. We think you'll be amazed. A 16 oz. bottle easily covers between 100 and 150 sq ft.
