Re: Hardibacker fixing?? | | I know that PL premium is a good adhesive for sticking CBU (it is a polyurethane subfloor adhesive and comes in the large format caulking tubes).
I typically use it on the corners as it is waterproof and strong.
Down side is the long drying time, although it will adhere to damp or even wet materials.
I also run a bead on the stud if there is no vapor barrier as it bonds the board really tight when used with screws.
When dry the job rings like a bell when tapped rather than rattle.
You should use spf when bonding it as a subfloor. |
