Foam underlay.


Hi All,

Please can someone answer the following for me,

I am in the process of laying some quick step laminate flooring, some area of the floor are about 10mm out, I have managed to use latex to levell most of it but still there is some height differences. the differences are only in a couple of areas.

I have the foam underlay with the damp proof couse built in and was wondering if it is adviseable to double up on the underlay or possibly buy some of the fibre underlay to use together.
I have heard this could give me a problem with too much flex uder the floor putting stresss on the joints,

Can anyone advise or even give me some clue on what else to do?

any comments are welcome.

Cheers

Mark.

do not double the pad, if your going through the trouble of installing it yourself do one more thing .get ahold of some mapei plani patch or some ardex feather finish and do one more coat of prep with an 18 in finishing trowell .the trowell and prep should cost atotal of 20 bucks well worth it. hold the blade of the trowell firm as you drag it across the floor. good luck with your project

Like mentioned you shouldn't double the pad up. You can use roofing felt or tar paper to layer up the difference.
