Noticed something at a job site in Phoenix last week
I was doing a tear-out at an old condo and saw the carpet padding had turned completely orange underneath the seams. The homeowner said they'd had a pet odor treatment done 6 months prior, and it looked like the chemical soaked through and stained the pad. Has anyone else seen that kind of reaction with those enzyme sprays on older padding?
Ran into that same orange staining on a few tear-outs where enzyme cleaner had been dumped on heavy. Once that pad gets soaked it holds the chem and it bleeds out over time, so replace the pad and treat the subfloor before you lay anything new.
