I know multi has changed over the years but I just don’t see how so many people are having problems working with it!! Maybe to many people are messing around with it to much and trying out different types of trowels, speedskims change it slightly, not sure what it is about them on finish but I don’t like it, I like them on render just before floating though, all these flexi trowels are rubbish as they pull up air bubbles in the finish. You just can’t beat a good worn in steel trowel, not a permashape one, do it yourself. Just my two pence and personal experience with them, I say stick with the steel and all will be fine.
Cheers
