ExoShield - Only The Finest Components

The use of Tung Oil originated thousands of years ago in China where it was used as a preservative on wooden ships. Today it is the woodworkers’ #1 choice to add protection and beauty to a finished project. ExoShield Deck Finish takes advantage of the penetrative and protective properties that Tung Oil serves to create a naturally durable and long-lasting deck finish. The Tung Oil used in ExoShield Deck Finish contributes to provide a naturally water-resistant, acid-resistant, and easy to use deck finish. It also greatly reduces the chances of boards either cracking or warping when correctly applied.

Fungicide is an essential component to maintaining the timeless beauty of your deck. ExoShield Deck Finish not only offers protection from harmful UV rays and water damage, but it also includes a fungicide in the formula that will keep your deck in top shape, and fungi free. This is just another reason why ExoShield is the answer for all exterior wood applications.

We use a trans-oxide pigment in ExoShield to protect your deck from harmful UV rays, adding to the longevity of the structure and color. The pigments used in ExoShield Deck Finish will bring out and protect the natural colors of the wood it’s used on, providing a long-lasting vivid result. ExoShield will lengthen the lifespan of your deck’s color, delaying the graying process. If applied once every one to two years, your deck will maintain a nearly brand-new appearance, with very little maintenance.

Product Application

ExoShield Deck Finish application is made easy for any user. Whether it be a homeowner or a contractor, anyone can correctly apply ExoShield.

Preparation. In order to correctly apply ExoShield Deck Finish, the first step is obtaining a very clean and smooth surface. Be sure to scrub your deck thoroughly removing all grime, dust, and any mildew that may exist. Standard consumer grade deck cleaners are available from both Messmer's and Deckwise. They are a combination of Sodium Percarbonate / Sodium Carbonate Peroxyhydrate and Soda Ash / Sodium Carbonate - when mixed with water, the cleaning solution can be applied to the deck surface with a garden chemical sprayer. After soaking in for 5-10 minutes, the deck should be thoroughly scrubbed with a stiff-bristle broom or brush and then rinsed thoroughly. It may take a two to three applications in order to remove several years worth of dirt and mildew, and fully restore the original color of the natural wood.

Many species of high density hardwood contain a high degree of tannins and tannic acid. These hardwoods include Ipe, Cumaru and Batu, as well as many others. As the final step before treatment with ExoShield, we recommend that a wood brightener is applied. Standard consumer grade wood brighteners are also available from both Messmer's and Deckwise. The brightener comes in powdered form again and consists of Oxalic Acid / Oxalic Acid Dihydrate. After applying the cleaner and or brightener, be sure to let the deck dry out completely which will usually take 2-3 days.

Even when finishing fresh wood, a completely dry surface is required. Do not finish your deck with ExoShield unless you have had a minimum of 2-3 days of dry weather and do not expect rain within 24-48 hours. If the deck surface does get wet soon after finishing, you will likely get water spots on the surface which must be sanded out prior to a light refinishing with ExoShield. After finishing, you should stay off your deck for at least 48 hours. ExoShield will take up to two weeks to fully cure to its final hardness. Many decks require some degree of sanding especially if they have aged more than a few years. In addition, if there are areas that have been badly weather-beaten or contain loose fibers, a light sanding using 80-100 grit sandpaper is necessary to smooth out the surface and remove unwanted blemishes.

It is absolutely critical that you do not over-apply ExoShield. More is not necessarily better - excessive finish on the surface of the wood which cannot be absorbed must be avoided. Over-applied finish must be sanded off and followed with a light reapplication of ExoShield.
