If you’re looking to maximize the life of your deck joists, Joist Guard is the perfect product! This product manufactured using a special adhesive that is designed to self-seal itself around wood, screws and nails, blocking pathways for water to absorb into your pressure treated wood.

How Does It Work?

The key to this product is the non-corrosive barrier created upon application. It creates an layer between the framing of your deck and the surface decking above. Designed to be applied to the top of deck joists, this unique barrier acts as a waterproof skin, preventing wood from rotting or decaying, over an extended period of time.
