Estimating and ordering Dexerdry
We recommend reviewing the Dexerdry installation process before ordering any materials for your project.
Dexerdry is installed with one piece between each deck board, so you should need the same linear footage of Dexerdry as you do grooved decking
Dexerdry should be inserted between deck boards, and the boards compressed together, then fastened to the framing.
Dexerdry will require a sealant at joints and other points during installation
Recommended sealants are shown below
When routing a groove in your PVC trim board at the house wall, the following grooving router bits should be used
