Prep TC roof for Dicor redo
Hey guys. Just wondering if you guys have a favourite cleaner for cleaning the old dicor before going over with new dicor self leveling sealant? Was gonna go with TSP and a bristle brush> Wipe ...

Anything will work.
Lap sealant is very sticky and will even stick to the dirty roof if you don't clean it so well. Do clean it, even if only scrubbing with a dry rag. The leaks will come from when the dicor cracks, not so much from the sealant coming un-stuck. I use rubbing alcohol and get the visible dirt clean and get most of the old sealant off, but I dont bother going crazy trying to perform surgery,
I do use the self-leveling on walls, it will run some, so you cannot put big beads on, but when it runs it means it is flowing into areas that the non-leveling might not get into.
