Clubhouse Dexerdry Weather-diverting System

Dexerdry is a one-of-a-kind, patented solution for weather-proofing all types of outside decks. This revolutionary system comprises thermoplastic inserts that fit perfectly between the grooves in your deck boards. Dexerdry completely water-proofs the deck surface while keeping the space underneath your deck dry and sheltered. The end result is a more livable, lower maintenance, and longer-lasting outdoor deck space.

Do note that we highly recommend using a board straightener/lever tool to tighten seams during installation of Dexerdry. Dexerdry additionally comes with a 25-year limited warranty for total peace of mind.

FAQs – Frequently Asked Questions

Q. How can I address any wicking issues?

A. Dexerdry recommends on all installations the use of a drip edge to protect the outside perimeter of the deck installation. The drip edge cut should be slightly deeper than the depth of the board slot. Another option would be to seal the outside edge of the boards and the Dexerdry flange with a sealant.

Q. How do I use Dexerdry on a deck that is larger than 20 feet, or am I required to run the deck boards in a certain direction?

A. Please view Dexerdry’s video about this by clicking here.

Q. Does Dexerdry require pitching the deck?

A. Yes, we recommend that the deck be pitched 1/8 of an inch per foot.

Q. Can I use the hidden fastener clips with Dexerdry?

A. No, Clubhouse clips occupy the same slot which is used by Dexerdry.

Q. What do you suggest for caulk? 

A. Lexal is a very common one found almost everywhere. The DAP is also a good one because it claims it won’t wash off soon after it’s applied. That means if you start working in the morning and it rains at 11:00am, you won’t have to worry about it.
