    Hi All

    Have browsed the forum for a number of years whilst renovating our house, but the time has come to sign up and ask you guys for some help. I am laying Amtico glue down parquet LVT in an old kitchen. I removed the old kitchen tiles and all of the adhesive, PVA the concrete floor, and poured setcrete latex self leveller. When you look at the floor it looks spot on, nice and smooth and flat.... however when i put my 1.8m straight edge over the floor there's a number of spots where i can get a 3mm packer under the flat edge, in one area a 4mm packer.

    My question is am i able to mark out these spots and use ardex feather finish to close the gaps under the straight edge? or do i need to do another attempt at self leveller? my concern is i don't want to do another levelling compound as i don't have the height in the transition from the old kitchen into the hall way area. i don't want to waste time doing a feather edge on those spots if it's going to affect the way the PS glue goes off etc.

    Thanks all for any help you can offer.

    Yeah just feather out the bad bits……
    If you’re a diy er then it will be right…….
    Correct way would have been to get a pro in do a damp test….. pva isn’t great as a primer especially if any damp present in the slab.
    How old is this old kitchen as any damp coming through is potentially gonna blow the screed and your ps adhesive won’t like it

    Hi, thank you for replying. The house is 19 years old, the house appears to have a DPM and there doesn't look to be any signs of damp but i didn't do a moisture test

    Cheers dazlight. Any tips for spreading the feather edge so I don’t end up with lines etc? Do you normally use a standard trowel? Thinking about laying it down then pulling straight edge over the floor so it lifts off any excess then tidying up with trowel?

    Just go light, leave it for 10mins then wet your trowel with a spray bottle or even a light spray over the feather and go over it lightly.

    I put it down thick, fill what I need to fill them scrape of excess with a trowel. First time you may over do it but seeing as you have a level just check it as your doing it
