Hi, I'm selfbuilding, hope someone can help with chosing adhesive for our floor.
We have black limestone slabs to lay over underfloor heating pipes (concrete slab base, 50mm kingspan and wet UFH pipes in sand cement screed) and need to know which is the right adhesive to use for it.
The floor slabs are uncalibrated between 25-35mm thickness.
We've been told we must use a flexible adhesive as the UFH will cause heating and cooling, there are many products on the market which makes it so confusing.
Also as the slabs are thick and the pipes are bedded in screed why does the floor adhesive need to be flexible, assuming the screed is not?
If it has to be flexible is there anything we can mix with sand cement to make it flexible (such as the bottles of latex available?) as we will need to have something we can lay at variable thicknesses to get the floor level?
What would be the most sensible solution?
Any help or suggestions are gratefully recieved.
thanks in advance
