    I've used it on quite a few jobs mate and like it.
    I was told by the laybond rep not to prime it though if your screeding it same day.
    So I do 1st coat 20 min wait
    2nd coat wait a hour
    Then screed.
    Found it works mate as not had a call back. I've done about 5 jobs with it.
    I hate the Screedmaster trade though as had 10 bags of that. Never using it again.

    No Matt not dusty never used 1k turbo, as daz says don't prime but why on the tub it says prime before screeding which does make it a bit tacky.

    just to note,

    The lack of primer. Your sticking screed to a impervious material (the dpm)

    They may say you dont need to prime if you install withing 12 hours etc maybe? if it goes longer then you need to prime.

    So bare in mind the above, lets say it does go wrong and they ask where is the proof of primer. Well there is no primer as you laid on it as instructed within the time period. PROVE IT !

    Lot of fitters coming into trouble with these 'no need to prime' systems. Cant name any names as a court case etc going on, but this is a regular thing we see.

    No mate it's not.
    This can only be used on a floor with a existing dpm.
    If no dpm and not sky high damp reading then I do below , but it's not guaranteed.
    If using laybond -
    If bit of old adhesive down or rough floor, screed with ultimate , no primer.
    Then 2 coats of one coat membrane
    Prime & screed.

    Trust me, there is not a surface dpm out there than can go over a floor with rising damp. You maybe lucky and get away with it. The water table for the house will make a big difference on if it will go wrong or not.


    Tell a lie, there is surface dpm systems like asphalt that can be used. But this uses its own weight to hold it self down. A painted on product has no weight behind it.
