Just got some general questions about SLC and how to make my life easier. How runny/flowable (technical terms) is the Ultra two ( @Nickfromwales ) part self leveling when mixed with the Latex? With having to bring the floor up 10mm over quite an area I was going to bulk it up with 6mm limestone pipe bedding and wondered how easy it will be to spread this? I know the best way would be to mix the aggregate prior to laying but the easier way is to sprinkle it in afterwards especially if it 10mm deep (ish).What about priming the floor beforehand as the place I am getting the compound from do not go into detail and some sites say let the primer dry before laying the compound and others say put compound down when primer is tacky.
