    Got to build a floor up 50mm so thinking deep fill latex with chippings, what's your recommendations on brand? Also bitumen residue left at moment and customer is asking for a liquid DPM so NA and Ardex DPM?

    Would you dpm before the latex and chippings or can I go on top before the final skim?

    Just checked, max depth NA with cippings 30mm. Balls 600 deep fill? Water based though.

    Be cheaper to put a plastic dpm sheet down and get a liquid cement pumped in

    Thats in 1 coat You can do it in 2 coats alough it will take a while for NA to dry that thick

    Grind off the bitumen and use CL it will dry better
