Hi
1933 semi detached 2 bedroom house.
I am planning to pour self levelling screed over the old slab, in what will be the kitchen, which will only be 15mm at deepest, and 4mm at most shallow. I've had a devil of a job getting a liquid DPM to stick before pouring the screed. I have removed about 3-4 mm off the top surface, swept it, hoovered and mopped it. I've used Drybase liquid DPM on various test patches. I've tried to apply it on
I have used a moisture content meter, pin type, and have a consistent reading of 1.2 - 1.4 % across the floor. I have no idea what is or isn't an acceptable moisture content. Is this a good figure? Am actually needing to paint a liquid DPM at all with this kind of reading? I'd rather do so in truth.
Thanks, really appreciate any advice

- clean but dry patch-barely adheres at all
- clean and damp patch-barely adheres at all
- with tacky SBR patch-only moderately better than above
- with dried acrylic primer-best adherence but still easy to peel away
