Some exotic woods contain tannin. Tannin is a natural extractive which reacts with water and leaves staining. It also increases the overall darkness on the wood after the water evaporates. Woodguard can help!
These types of woods therefore need specific protection to prevent tannins from migrating to the surface of the wood. Guard Industrie has just developed WoodGuard Bloqueur de Tannin, a primer designed to block tannin. You can apply WoodGuard Bloqueur de Tannin to all types of woods which contain tannins. This includes cladding, parquet floors, terraces, garden furniture and more.
