Amazing Tools B3 Heavy Duty Professional Mixer for Epoxy, Paint, Mud, Grout, Thin Set, Plaster, Cement Topping, Dry Wall etc 20" Unique Configuration, Mighty Red

In the last few days, I have mixed about 20 bags of sand with Portland cement, and 20 bags of Quickcrete cement. The sand/Portland was dry-mix. The Quickcrete had water added.I use the 2-bucket method -- divide a bag of material into two buckets, add the ingredients, then mix. Thirty-ish pounds of material is a lot easier to carry from the mixing site to the hole than 60 or 80. I used a half-inch drill-driver on low-speed, in reverse (left hand turn). That lifts material from the bottom of the bucket, and turns the contents over. It also allows me to use the torque of the drill to steer the mixer around the bottom. Thirty-seconds or so of mixing per bucket does the trick.My back hurts a lot less than it ever has before, after mixing and placing any similar amount of concrete. That, by itself, is well worth the price.I do expect the thing to wear out eventually. It's not a permanent tool. It is a "bit", and I am sure it will wear out. But when it does, I will buy another.My only suggestion for improvement would be a longer shaft. I would like to operate the drill to mix a bucket without having to bend over.

This mixer works great. I use it to mix mortar in a 3 gallon bucket for small masonry jobs. I run it in reverse at slow speed and it pulls the dry material out of the bottom corners of the bucket so there is no unmixed mortar in the bottom of the bucket. It is easy to clean. I hold it above the mortar and run it at high speed for maybe a second, and most of the mortar comes off of it. Then I run it for a few seconds in a coffee can full of water, and it is clean. It is certainly far superior to mixing mortar by hand.

Paint does chip off this mixer. If you are using this for an application that cannot have contaminants in your slurry, I'd recommend looking for a Stainless Steel option. For the price, this is an okay option.

I use this to mix clay; the paint/finish chips off, the shaft gets stripped relatively quickly (so it sometimes spins/ sometimes falls out of drill)... not great, but not as bad as others I've tried... mixing clay for a pottery studio in 5 gallon buckets is pretty heavy-duty and I have destroyed the welds on other mixers after one use... so this one is okay with me. (I've bought it twice and will buy a third when I need one if I don't find something better)

I bought this to mix compost, potting soil, and mulch. It works great with an electric drill! Be careful to tighten the bit clamp well and check often as the wobble of the mixer will loosen the grip. I noticed another reviewer had suggested that the reverse direction works better so I tried it. Compared to the forward direction (right spin) the reverse spin works much better at pulling up materials from below and churning it up to the top layer. Many thanks to the "reverse direction" reviewer.

ok

I got this to mix concrete, so if you are using it for something thinner like mortar mix it will probably work a lot better. For concrete in one direction it pushed it right down to the bottom of the bucket and was too hard to pull back out, if I reversed it it worked better but the paddles push and pull to much in the thicker concrete mix.

This thing is great!! I use it to mix thin-set for tiles, Mortar for the mortar bed. Concrete for concrete work. I have not tried it on paint. The red paint will chip away so you should try to clean it or keep it submerged in a bucket of water so it is easier to clean afterwards. Has not rusted out yet even with the paint gone in some parts. This is a heavy duty mixer.
