I'm a new member and a complete novice at diy-ing but due to the amount of things that need done in my home, I could become quite a regular. Here's my current problem ...
I had a leak in the roof (dodgy tile, now replaced) but this brought water into the bathroom and thus weakened the ceiling. I tried to paint the ceiling (damp proof, stain removal ronseal stuff) and some of the plaster came off the ceiling. I stuffed it with pollyfilla and returned the next day, when the contents of the hole including the filla, duly fell out. I now have a hole (approx diamater of a coffee mug) going from bathroom to attic.
I have a can of expanding foam filler and am wondering if I squirted this stuff into the hole would it fill it and fix the problem ? According to the can it seals, bonds, damp proofs and all that.
Any suggestions most welcome.
