Hi. Ive a customer that is going to fit an electric heating system under the Massimo she wants. I've never done the preparation for this kind of use, its always been done before I have fitted LVT. Is there a certain screed to use? Help would be greatly appreciated as I am in two minds to leave it. Nick
Screed ontop of ufh i would always use a fibre one mapei renovation. Stick the mat down if its self adhesive if its not then a couple of coats of primer should hold it then a decent 5mm screed to encase the cables then 2 more coats on top most manufactures reccomend about7mm of screed on top of the cables so just be prepared itll take a lot of bags
I’ve done a few of these.... Flooring grade ply, well fixed and make sure any loose boards are well fixed and not lots of flex in floor. Mat rolled out into position, most are self adhesive but matting comes loose when screed is applied so some spray adhesive may help. Then I apply n/a let it dry then another coat on top to make sure the cables are well covered. Think eurocol 902 May be suitable as well or other manufacturers if you check.... not had n/a fail yet so kept using it, also used mapei renovation but mixed thick and took longer to set
