Sealing back of arlington in box and also stem wall to sole plate at interior?
Hey all – 2 questions:
1) I have a few Arlington in box’s installed on my construction project. They are great, but the various pre-punched knockouts are not well sealed. I plan to spray foam this building. Should I leave it to the spray foam to seal these up, or should I apply some sealant (OSI Quad Max), or liquid flash, or? First photo attached is the interior view (backside) of one of these boxes.
2) I learned a lot about air sealing during the construction process. Unfortunately I did not seal tape/liquid flash at the exterior between my concrete pad (stem wall) to sole plate at the exterior walls prior to stucco. A builder grade foam gasket was used. This joint at the interior is still accessible, and will eventually be mostly covered by drywall, so I would like to seal it at the interior while I have the opportunity. Similar question to above – what product would be best here: liquid flash, OSI quad, tape, or something else? Second photo attached depicts interior view of sole plate atop stem wall.
Thanks everyone!

I would probably use a liquid flashing product but I would make sure that the product I want to use is compatible with the materials I am applying it to. You can find out this from the manufacturer and some pictures of the area would be appropriate. I would also ask for a letter confirming the compatibility. If you cannot get that then use a different product.
Unrelated to your question, but why did you use conduit for the wiring? Just curious.
Tim_William: Building was put up 2 years ago and was planned to be insulated and drywalled at a later date - so since the Romex was exposed, the local inspector required it to be protected up to a certain height (8ft I believe).
Makes sense, thanks for answering!
