i had a load turn up to a 8000x800 porc on wet ufh job. the builder was laughed at. i believe it's only good for ceramic/quarries up to 300mm on solid walls and floors but wouldn't touch it with a barge pole
Crazy thing is I have visited the Mapei factory in Halesowen a couple of times and not once seen any of this stuff either palletted, being made or the empty roll of bags ready to be filled. It's not made by someone somewhere else is it!? @Mapei UK Marketing can you answer?
