Preventing and stopping wood rot is the most important aspect to consider when building a deck. Trapped moisture between surfaces is the enemy and causes wood rot, shortening the wellbeing of your deck. WiseWrap® LedgerTape® flashing barrier tape is placed on the ledger board and up the wall of the house. Its "super Grip" adhesive sticks tight, keeping water drainage from seeping between the boards. LedgerTape® is also perfect for wood deck posts to prevent rot beneath the soil surface. Apply to any wood post such as fence posts and mail boxes to extend their lifespan for many more years.
