Just started a remodel of my home and doing a 2400sf luxury vinyl plank project in my home. I’ll be doing upstairs and below grade basement. I purchased cortec pro plus flooring. I’m currently setting up to battle a not very flat or level OSB subfloor in a 2008 era spec home. I’m playing with the idea of using triton backer board as an underlayment. An idea given to me from a concrete polishing contractor. He’s also tested a few panels with an epoxy application that we may try out in my laundry room.
