It’s like welding but with foam

Whoever cut that hole needs to not be the one cutting holes.

We used to build pyramids?

Pretty sure that’s the stuff they use for Kamala’s brain

Why would anyone do a cutout that large to begin with?

Great job insulating a piece of bare drywall lol There’s no other insulation on the wall, So exactly what is the point? Also it probably looks like ass on the outside

Using foam to fix a hole way out of proportion to the plumbing fixture? This drain runs outside from inside? Let's fix our lack of craftsmanship with.......foam?

I see the previous owner of our home is still out there being handy

Ugly but it works

This is going to hold up forever!
