looking at buying a quattro are they any good for k rend any other usefull info on them would be great thanks paul

Paul,

Have just replied to your previous post about the Quattro and pumping K Rend. An on-site demo is what you need. But in brief, with standard equipment the Quattro will pump all machine applied renders, as well as Knauf MP75 internal plaster. Thistle Hardwall & Tough Coat will pump fine, but generally I don't recommend pumping Gypsum based materials. (Have you ever noticed that rarely one mix of plaster will hold exactly the same amount of water to another? They generally always vary, even if only slightly. And that's because the grades of gypsum throughout entire sections of quarry vary and this can't physically be controlled. That's why one bag of plaster my require slightly more or less water to reach the same consistency as another.) This can present a little bit of problem (but not insurmountable) when mixing and pumping through a machine.

But anyway, where were we? Ah yes, renders. No problem. All day long.
