Deck Waterproofing and Sealing Process in Seattle

Testing Moisture Levels

Residual moisture is one of the major causes of waterproofing failure, particularly for outdoor spaces such as patio, porches, balconies, outdoor stairs and pool decks. 

To address this, the first step of the process is to test for moisture levels. This identifies which areas have elevated moisture content.

The Substrate and Joint Preparation

After testing moisture levels we then prepare the substrate and joints for installation. These are cleaned to remove dirt and debris. Joints are filled in with a patching compound.

Redirecting Water Runoff

To direct water runoff away from the deck, metal flashings are covered with PVC. This is then used to create a drip edge to allow water runoff. To ensure that no gap collects water runoff, galvanized flashing is also installed.

Waterproof Coating and Sealant Application

 number of moisture mitigating coatings are available for sealing application. The deck sealant Seattle builder or installer will recommend one depending on the condition of the deck. 

This is then applied to protect the deck from water and moisture.
