    You don’t have to if your latexing the day after the dpm. If it’s been walked all over pr site probably best to prime

    Best way to prime DPM is to yuck a load of kiln dried sand on it before it dries

    NA does a Job but the flow is terrible I’d personally use CL screed if it had the be an Ardex product

    PS is very weak and no better than a tackifier
    LVT expands and contracts with temp change
    More so with wood plank and large tiles so with PS you can get gapping or tenting
