Refina MM19/1 Mega Mixer Review

Looking for a mixer that can take on tough plastering jobs and not let you down? The Refina MM19/1 Mega Mixer could be what you're after for your next project.

This mixer’s 1000w motor spins at 450rpm, so you've got enough muscle to blend up hefty batches of plaster or coatings. It’ll handle mixing loads from 25kg up to 50kg, with an output rate of 400kg per hour—so you’re not left twiddling your thumbs between mixes.

It’s only 3.1kg, which is light enough for longer jobs, and the back and hoop handle design gives you a reassuring grip. The included paddle is a 5-inch MR3 130G, but you can swap it out if you need something different for another job.

Made in Germany, the build feels solid, and there’s a one-year guarantee covering both the tool and paddle. Variable speed and soft start features give you more control, especially when you’re working with trickier materials.

Bottom Line

If you want a mixer that’s going to be dependable for plaster and coatings, the Refina MM19/1 is worth a closer look. Check it out on Amazon and see if it ticks your boxes.

Overview: Refina Plaster Mixer MM19/1 1000W 240V

Mixing plaster by hand is a slog. This tool from Refina is designed to speed things up and give you a smoother finish with less hassle.

Built by Eibenstock in Germany, it runs a 1000W motor at 450rpm, and at just over 3kg you can hold it with one hand while mixing with the other, thanks to the back and hoop handle.

Here’s a quick glance at the specs:

There’s a decent selection of paddle attachments available, so you can go small or big depending on the job. The 1-year guarantee covers both the tool and paddle, so if anything goes sideways early on, you’re covered.

1000W High-Torque Motor

With 1000 watts, you’ve got enough grunt for mixing thick materials like plaster and render. The 450rpm speed is more about torque than spinning fast, so it’ll push through heavy loads without choking out.

You can mix batches from 25kg to 50kg, and the 400kg per hour output is plenty for most plastering jobs.

Noise is 71dBA, which is about what you’d expect, and vibration is rated at 1.9m/s. Nothing out of the ordinary there, though you might want ear protection for longer stints.

At 3.1kg, the motor unit is light enough to handle with one hand while you manage the paddle with the other.

Soft Start And Variable Speed Control

It’s always a pain when a mixer jolts to life at full blast. The soft start feature here is genuinely useful—it ramps up the power gently, so you’re not splashing mix everywhere right out of the gate.

Variable speed control lets you dial in the pace for whatever you’re mixing. Thicker plasters need a slower, steadier hand; thinner stuff can take more speed.

These features give you a bit more predictability and control, especially when you’re dealing with big batches or finicky materials.

MR3 130G Paddle Performance

The paddle is where the heavy lifting happens, and this one’s up for it.

At 5 inches wide, it’s right in the sweet spot for mixing 25–50kg batches—pretty much what you’d want for most plaster and coating jobs. The output rate of about 400kg per hour means you’re not waiting around for ages between mixes.

Some highlights of the paddle setup:

• Made in Germany—so you’d expect it to last
• Interchangeable design—swap it out for other sizes if you need
• Designed to work with the 450rpm motor for consistent mixing

Just remember, this paddle is set up for a certain batch size. If you’re always doing tiny or massive mixes, you might want to look at other paddle options.

Back And Hoop Handle Design

The handle setup is all about control. You get a rear handle and a front hoop, so you’ve got two solid grip points.

This makes it easier to keep steady, even when the paddle’s chewing through a thick or heavy mix. Plus, you don’t have to hunch over as much as you would with shorter drill mixers—good news for your back.

What stands out with this handle design:

• Two-point grip for better balance and control
• Less strain on your back and arms
• Sturdy build for heavy-duty work

The flip side? It’s a bit bulkier than compact drill mixers. If you’re used to smaller tools, this one will feel a bit heftier.

Batch Capacity And Mixing Applications

Batch size is a big deal when picking a mixer. The Mega Mixer is built for medium-sized batches, making it a handy pick if you’re after consistent results on plastering or coating jobs.

Suitable Plaster And Coating Quantities

With the standard paddle, you’re looking at 25–50kg per batch. The 450rpm motor keeps things moving at about 400kg per hour, so your workflow shouldn’t stall.

Swap out for different paddles, and you can go anywhere from 1 litre up to 150kg—handy if your job sizes vary a lot.

For everyday plastering, it’ll handle a couple of bags of finish without a fuss, which is great for tradespeople who don’t always need giant batches.

Here’s a quick breakdown:

Build Quality And Service Support

This mixer feels robust right out of the box. With a heavy-duty motor and a tough gearbox, it’s clearly designed for regular use.

The handle setup—back grip and hoop—makes it easier to keep control, especially with thick plaster or coatings. That’s important when you don’t want the tool twisting out of your hands mid-mix.

What stands out:

• German manufacturing—usually a good sign for durability
• One-year guarantee on both tool and paddle
• Plenty of spare parts available at decent prices
• Nationwide collection and repair if you run into trouble

You get the impression Refina has put some thought into aftercare, not just the initial sale. That kind of support can really matter over time.

Long-Term Ownership Considerations

If you’re planning on using this mixer regularly, you’ll probably get years out of it. Some users mention running similar models for over a decade without major headaches.

With genuine spares easy to find, you’re not left high and dry if something wears out. That’s a big plus if you want a tool that’ll last well beyond the first couple of years.

Who This Mixer Suits

If you need a tool that can take on heavy-duty mixing jobs and keep up, this one’s a solid bet. It’s made for those who want reliable power—not something that’ll bog down or feel flimsy after a few tough jobs.

Professional And Regular Trade Use

This mixer suits tradespeople who mix plaster, render, or coatings on a regular basis. With a heavy-duty motor and a gearbox that's built to last, it's clearly aimed at folks who need something that can handle frequent use and not just the odd job here and there.

If you’re mixing larger amounts—think 25kg up to 50kg—this machine doesn’t seem to flinch. The back and hoop handle combo is a thoughtful touch, giving you more control and making those long mixing sessions a bit less punishing on your arms and back.

If you’re just dabbling in DIY and only need a mixer once in a blue moon, you might find this is more than you bargained for. It’s really made for people who’ll be dragging it out of the van several times a week, not just once in a while.

Reliability And Power Feedback

Long-term, this mixer seems to hold up. One user mentioned theirs is still going strong after more than a decade of regular use—several days a week, no less. That sort of thing doesn’t happen by accident.

For smaller batches—say, two or three bags of finish at a time—users don’t report any problems. The motor’s got enough grunt for everyday jobs, though if you’re thinking of going much bigger, you’ll want to double-check the specs first.

Price-wise, most buyers seem happy. It’s often cheaper than going through main dealers, but you’re not getting something flimsy or second-rate for the lower price.

Frequently Asked Questions

Still got questions before pulling the trigger on this mixer? Makes sense. Here’s a straight-up look at what people usually want to know.

How powerful is the 110V twin-paddle mixer for plastering and rendering materials?

This mixer’s running a 1000w motor, so it’s got plenty of punch for mixing plaster and render. It spins at about 450rpm, which is basically the sweet spot for thick building materials—not watery stuff.

Both 110v and 240v versions are available, so you can pick what fits your site. The power stays the same either way, so you’re not missing out if you go with 110v.

Is this mixer suitable for mixing large batches of plaster, mortar and cementitious compounds?

Yeah, it’s designed for bigger jobs. You’re looking at a capacity between 25kg and 50kg per mix, with an output of roughly 400kg per hour.

That’s enough to keep up a decent pace on site. This isn’t just for the odd little DIY project—it’s for regular, repeated use.

Key points to note:

• Handles batches from small tester amounts up to 50kg
• Works with a range of paddle sizes for different materials
• Suited to plaster, render, mortar, and similar cementitious mixes

How does the twin-paddle action compare with a standard single-paddle mixing drill?

Twin paddles generally give you a more even mix than a single paddle. Both work through the material from different angles, so you break up lumps faster and blend everything more thoroughly.

Compared to a single-paddle drill, you’ll probably notice you don’t have to guide it as much to get a consistent mix. It saves time and cuts down on the effort required to stir by hand.

Is the mixer easy to control when mixing heavy or high-viscosity materials?

The back and hoop handles help you keep a steady grip, especially when you’re mixing thick, heavy stuff. Having both hands on the tool means you’re not fighting the twisting force of the paddles alone.

It’s got soft start and variable speed, which are handy for thick mixes. Soft start keeps it from jerking when you switch it on, and variable speed lets you adjust for whatever you’re mixing.

What build quality and durability can users expect from this professional power tool?

It’s German made, with a heavy-duty motor and a long-life gearbox—definitely not a throwaway tool. Built to stand up to frequent, tough use, not just the occasional light job.

The tool itself weighs about 3.1kg, and the full package is around 7.12kg with the paddle and packaging. That’s light enough to handle but still feels solid in your hands—important if you’re using it all day.

Here’s a quick summary of what’s covered under support:

That level of backup shows the manufacturer expects you to put this tool through its paces and actually wants to support it—definitely not just a disposable bit of kit.

Is it a worthwhile choice for professional plasterers and rendering contractors?

Looking at what this mixer brings to the table, I'd say it's a strong option if you're dealing with plaster or render on a regular basis. The motor's got some punch, it's got a decent batch capacity, and those interchangeable paddles mean you won't be juggling a bunch of different tools for every job.

Honestly, it's probably overkill for the occasional DIYer—pricey, and just more power than you'd ever need in a home setting. But for contractors mixing day in and day out, it feels like it's designed to take that kind of punishment.

I've heard from folks who've run similar mixers for years without major hiccups, so that's encouraging for long-term use. Of course, as with any tool, a lot comes down to how you treat it and how much work you put it through.
