Hi thanks for the help on this great site, I am laying a patio and have followed the video of laying a block edge course, instead of blocks I am using a 100mm2 stone but I can't get them to bond to the 6:1 sharp sand cement base the next day I can lift the blocks straight up with little effort any tips? I have also haunched the blocks on the back side ,cheers 🤔

Make sure you keep your kit clean and wash out the mixer after each mix as it goes off quick and solid if any drops on top of any slabs clean it off quick
There is some info in the main site about it

Thanks again, I have read on the main site about mixing the sbr slurry mix, what quantities would you recommend to add when adding the sbr to the mortar mix?
