Hi.
Is there a best way to "Glue" PIR to a concrete floor. I have an existing screed of 70mm that I am replacing with 20mm PIR and 50mm flowing screed, just wanted to make the boards a little more secure while installing UFH pipes, etc.
My plan was for a few blobs of spray foam with a few heavy blocks on top of the board while it goes off, that stuff seems to stick to everything, even the stuff you don't want it to stick to!
Cheers.
