Identify Gaps and Prepare Foam Application

What happens here

Underneath the sink, the presenter points out the existing holes where the drain pipe and water supply lines emerge from the wall. These holes are larger than necessary and expose the wall interior, which is the target for this project. He then reiterates the use of DAPtex Plus foam sealant for filling these gaps. He notes a minor setback: the small applicator tip for the foam can is missing, indicating that some mess might occur, but reassures that the water clean-up feature will be beneficial.

Goal: The presenter moves under the sink to visually identify the specific gaps around the drain and water supply lines that need filling, and prepares the foam sealant for application.
