Help with shower subfloor
Hello,
I had ants coming from a hole in the caulking near an upstairs shower. When I removed the caulking, I noticed the peel and stick tile, and subfloor looks like this. I am hoping to try the following to get this fixed and I am interested in knowing if there is a better way to do this. A gut isn’t on the books for another 3 years or more. The crumbling portion of the subfloor is about ~1” from the shower, but not everywhere, only a ~4” section. I was hoping to apply mold control to the subfloor and then scrub to get the area clean. I then was going to seal/prime the plywood and apply new peel and stick tile over the area. Once I’m done with this, I’ll silicone caulk. Looking for advice on how this sounds, please and thank you!
