Good evening all,
I've bought some Weber Floor Flex levelling compound (fibre reinforced), as I could not get hold of Mapie fibreplan in my local area. The place where I got my Weber didn't have the weber pr360 primer.

My question is can I use Mapei's primer g instead? It will just save me a lot of time trying to source the Weber Primer. I believe the Mapei primer can be used prime substrates prior to laying self levelling compounds.

The levelling compound is going onto 10mm marmox boards to bed in the UFH, which are cemetitous, and the surface is absolutely clean & dry.
regards

Not sure if you need to prime Marmox. I try to use same primer as slc/ adhesive, I would check with tech depts to be sure
