We have just extended our kitchen. The 'old' part of the floor now amounts to about a quarter of the total floor space in the room and is slightly higher than the rest of the new concrete floor.
The stud walls/first fix electrics are just being done at the moment. The kitchen is due to fitted next month.
We are planning to have Amtico installed. Our builder's floor fitter is amtico registered but he's not actually the cheapest quote we've had (in fact, John Lewis are cheaper).
I know we have to treat the new concrete floor for damp. Obviously, waiting for it to dry at an inch a month isn't going to be practical so I understand we need to lay a damp proof membrane.
I also know the floor needs to be leveled.
John Lewis advise that the DPM ought to be laid at the same time as the amtico or if it's laid beforehand then nobody ought to walk on it.
I have some questions I hope somebody can answer!
(1) Which is laid first, the DPM or the self-level?
(2) Is there any particular grade/type of DPM that you are supposed to use with Amtico? John Lewis want to do a damp test before fitting so I want it to be the right stuff.
Thanks in advance.
