Adhesive and Grout Mixing - TilersForums.com

[Julian 'Farmer' Bonsall]

I looked for some data on the mixing speed and size / type of paddle some time back. I noted most paddle mixers were around 700-800 rpm but the Rubimix is a two paddle two speed gearbox machine.

• Electronic regulator (1st 0-450 r.p.m. / 2nd 0-780 r.p.m.).Ø maximum paddle: 160 mm.

I couldn't spot data from the adhesive manufacturers. I have been using a drill also (Dewalt battery 996, 3 speed, 0-500/1500/2250 plus the electronic trigger. I use a 600mm paddle in the drill at the 0-500.

Would anyone have advice on what the mix speeds should be, if the two paddle is better/worse/irrelevant and if there is any manufacturer's data?
