GreenShield is based on a patented organo-silane technology (OST) developed by the company. Designed to shield wood and paper materials such as lumber, log, plywood, dry wall and more from the outside environment such as water, moisture, and even fire, GreenShield penetrates and encapsulates the material at a molecular level creating a composite material of wood (or paper) and a type of ceramic.

GreenShield can be applied by brush, spray, dipping, or a pressure-treatment process. It is a clear thin liquid and crystallizes within the material in very short time only reacting with the moisture in the air and the material itself.
