Waterproofing Deck Spacers
If you’re looking to create dry outdoor space below a deck, add a rubber mallet to your toolbox to install Dexerdry as part of your next deck project. These above-joist flanges act as spacers for grooved deck boards and form a watertight seal between boards. The rubber flange strips are reportedly UV-resistant, remain flexible in freezing temperatures, and can withstand 3,000-psi powerwashing. dexerdry.com
