Installer is used to using RS LevelQuick, but I went to Lowes and bought MAPEI Level Plus and Primer T instead. Anyway, I saw he was mixing the bottle of Primer T with the Level Plus, he also said it was 1 bottle to 1 50 Lb Bag. We had 10 bags that have been used so far.
I looked this morning and walked around on the floor (subfloor is plywood). Everything appears normal. Floor will be LVP.
Could this possibly be OK? Yes I know it is not as per manufacturers instructions.
