Hi everyone,
I was planning on having a liquid screed over my underfloor heating pipes and had in my head a nice 75mm thick design (to retain plenty of heat).
My design is 110mm concrete, 100mm insulation, 75mm screed.
This was to create a fairly level threshold through rear bifold doors
I’ve since discovered though that Anhydrate/liquid screeds have a maximum thickness (55/60mm seems to be commonly referred to) but I can’t find out why this is?
Is it because the curing time would be stupidly long, would it make the UFH less efficient, some other reason?
If anyone’s knows it would be really helpful.
Hoping it’s just drying/curing time as I’ll have plenty of time prior to covering (around 4 months)
PS I know traditional sand and cement would be ideal at 75mm so not looking for solutions but instead, err education I guess!
Cheers
