    Need some advice on yellow blisters in our cabin chink

    I have developed some bright yellow blisters in our cabin chink. Anyone know what these might be caused by? Any thoughts on repairing and remediating? Thanks a ton.

    Here are the pics:

    Yep...didn’t work, but those links will take you to the ImgBB page where they are hosted at. It’s a free image hosting service.

    That looks a lot like expanding foam.....

    Are you saying that this magically appeared on its own?

    My guess too. Did you build it or someone else?

    It looks like it was chinked with Permachink on one side, then spray foamed from the other side before Chinking the other side.

    Just my guess.

    Looks like spray foam, but also looks like it might be mold. Can you scrape it off?

    Just acquired a property with a cabin guest house. Never really inspected the cabin until we took ownership. Frankly, I don’t even know how old it is. It’s quite small, and did not offer much to enhance the value of the property itself. Now my wife wants to “fix it up” and in the course of looking it over, I noticed these blisters. I tried a Google search and came up empty. I figured I would try and find some experts to assist my efforts. I hope this extra info lends context.

    Looks like aerosol spray foam. Scrape some off, should be dry.

    Heading back to the property early this week. What would they have used yellow spray foam insulation for in so many different places? And why not simply use white?

    Have you ever seen white foam insulation?
