Using the drill for mixing concrete is very simple. First of all, we have to mount the appropriate mixing rod depending on the type of material that we are going to mix (paint, mortar, Concrete, etc.).
The best drill for mixing concrete can also be used as paint mixers and very useful for kneading one or two sacks of mortar in interior works where there is no small electric mixer that goes through the doors.
F2C Pro 1600W Adjustable 7 Speed Handheld Electric Concrete Mixer
Innovative mortar mixer that offers the possibility of adjusting the height of the tool to suit different users. According to Rubi itself, the F2C Pro is the first cement mixer to incorporate this feature. The regulation of the handle is a quality that, undoubtedly, the highest users will appreciate since the rest of beaters are short and force them to adopt an uncomfortable posture that results in discomfort and back pain.
With its powerful motor, the F2C Pro mixer is probably one of the best cement mixers on the market: it is very reliable and has great mixing capacity. Its bi-material grip (plastic and rubber) offers greater comfort and stability even in long sessions of use. Also noteworthy is the fast connection system Rubi Fast-In that facilitates changing the rod without the need for a fixed key.

What is a mortar mixer?
Everyone knows the spiral mixer used in hammer drills to beat paint or prepare glue mortar (cementitious adhesive). Although this accessory is useful for these tasks, it is not the most suitable due to its size (short and small) and the high number of revolutions of the drill. The mortar mixer was designed for this specific task.
The mixing rod of a mortar mixer is larger and longer than the drill accessories. Its motor is specially designed to offer a high torque with a low number of revolutions (which prevents the entry of air into the mixture). In addition, the mortar mixer is easier to use thanks to its vertical format with double handle to hold it with both hands.
This tool allows us to efficiently mix various construction materials: liquids (paints, self-leveling mortars) or semi-fluid (sand and cement mortar, adhesive for ceramic or porcelain tiles, plaster, plaster, lime stucco, clay coatings, etc. .).
Features and benefits of the mortar mixer versus the mixing sticks
Almost everyone has some sort of corded drill or cordless screwdriver among their DIY tools. Mixing rods, on the other hand, are very inexpensive, so why buy a mortar mixer? Let’s see its advantages.
First, as previously noted, the cement mixer has a format that makes it more convenient to use. Hand drills have their grip positioned perpendicular to the chuck axis. This is ideal for drilling and screwing but not for mixing mortar. On the other hand, mixer mixers have a double handle located in the same vertical position as the mixer rod. This would be the main advantage: the posture of the wrist is not forced and there is better control over the machine.
On the other hand, the electric motor of a hammer drill or combination screwdriver is not designed to beat, but to drill and screw. Consequently, both the number of revolutions and the power of the machine are designed for this purpose.
Let’s look at a concrete mixer: the tank is large but the speed of rotation is very slow. When mixing cement and sand, enough force is required to homogenize the materials, but not speed. In fact, excessive revolutions can cause air bubbles to form and become occluded in the mix: this often happens with materials such as cementitious cement or self-leveling mortar.
Therefore, the second advantage of the mortar mixer is that its powerful electric motor favors a high turning torque (motor torque) and a low number of revolutions per minute (~ 500-1000 rpm): ideal for mixing paints and cementitious mortars.
Mixing Rod Types
In the market we will find different types of rods depending on the material we want to mix. Fundamentally, we found two groups: the rods for painting and liquid materials and the mixers for cements and mortars. The rod holder on most models includes a 14 metric nut (M14) allowing replacement of the accessory whenever necessary.
For the churning of dense, compact and thick materials such as sand and cement mortar or concrete, the ascending mixing rods facilitate the work since, by pushing the mixture upwards, they avoid the formation of lumps in the bottom of the carrycot or bucket working. On the other hand, we will find different sizes of mixer rods. The larger its diameter, the more power the whisk will have to have. Some of the manufacturers indicate the minimum required power of the mixer (it is essential to take this into account to avoid overheating or burning the motor of our mixer).
Makes and models of mortar and paint mixers
Two of the best mortar mixer brands are DEWALT and Rubi. These two brands are specialized in the manufacture of construction tools, such as a trowel or flat trowels, and therefore offer high-performance models with benefits indicated for professional use.
In addition, general power tool and machinery manufacturers such as VIVOHOME, DELWAT or Nordstrand also have this powerful tool in their machine catalogs. The cement mixers of these brands are somewhat cheaper than the professional ones (VIVOHOME and DELWAT). In exchange, their design and features are also inferior (for example, they tend to have less ergonomics).
Frequently Asked Questions
What are the differences between cheap mortar mixers and high-end professionals?
The main differences are: the power of the motor, the quality and durability of its components, the ergonomics of the tool. In addition, professional construction mixers often include additional features such as double mechanical speed (using gears), soft start, constant electronics for speed stabilization, or an advanced design (Rubi, for example, offers height adjustable beaters).
Is the mixing wand and case included with the tool?
Virtually all machines include at least one mixing stick. As for the briefcase, the cheapest does not usually include it (they are presented in a cardboard box) while the best models do include a plastic suitcase for transport.
In addition to paint, what kind of materials can be mixed with a mixer?
The construction mixers are used to mix different types of mortars for construction: cement and sand mortar, mixed lime mortar, clay and clay mortars (used in bio construction), plaster, plaster, etc. The preparation of concrete (cement, sand, and gravel) is also possible in the most powerful models. In addition, this tool can also prepare coatings such as single-layer plasters or sand and lime stucco.
Another common use that is given to the paint mixer, in fact is one of the most common, is the whipping of cementitious adhesives (glue cement) for gluing tiles. And of course, any mixer, even the least powerful ones, are capable of perfectly mixing and homogenizing all types of paint and resins (epoxy, self-leveling, etc.).
Do you have intensity regulation on the trigger?
It depends on the model. The best mixers do include an electronic speed regulator that limits the number of revolutions to prevent very fluid mixtures from splashing. If the trigger is also progressive (soft start), you can start to beat at low speed and increase the revolutions as the mixture gains consistency.
Is the motor reversible?
It is not and it is not something that is necessary for the intended use of the tool
Can rods be purchased separately?
Yes, the current market standard mounts rod holders with M14 thread. With the help of a pair of fixed wrenches (or only one, if it has a spindle lock), the mixing rod can be removed and replaced by another.
Do I need to replace the carbon brushes on the motor?
Yes, most mixer manufacturers use conventional motors that rely on carbon brushes for armature rotation. The periodic replacement of the brushes is a necessary maintenance operation to avoid electrical breakdowns in the deltas collector. The brush holder is usually located on one side of the housing.
The mixer vibrates and wobbles during use, is this normal?
During the mixing operation it is normal to notice a certain level of vibrations. If the vibrations are excessively bothersome and the machine wobbles, the problem may be caused by a bent or off-center mixer rod.
Does the mixture splash?
If the appropriate rod is used and the speed regulator is used, the mixer hardly splashes. It also depends on the type of material to be mixed, fluid materials such as paint, resin or inconsistent mortars splash a little more.
Can you dock it on a mixing cube and make it work hands-free?
It is not a use that is contemplated by the manufacturer. The machine is indicated to be grasped by both handles. However, some users make modifications to the machine by attaching it to a container in order to have a semi-automatic mixer. However, to prepare a homogeneous mixture with a mortar mixer, it is essential to play with the height and position of the rod on the bucket to avoid lumps, which is more difficult to automate.
What is the best brand of construction mixers?
Rubi brand mixers are the best valued. This company is specialized in the manufacture of tools for construction professionals and more specifically, for tilers and tilers (tile cutters, ceramic cutters, trowels and trowels, etc.).
Rubi tests its mixers with professional users, before launching them on the market, to improve and optimize the machine’s performance. Likewise, during this trial period, Rubi receives criticism and advice from real users that serve to improve negative aspects of the tool or incorporate features not considered during the design phase (ergonomics, height adjustment, etc.). Another good brand of mortar and paint mixers is Acorn (Rubi’s direct competition in the construction sector).
How to clean the mixing stick?
During the working day, it is useful to have a second bucket, filled with clean water, to clean the mixer once the mixing is done. To do this, simply rotate the machine in the water at medium-slow speed (to avoid splashing). However, at the end of the day the rod will be thoroughly cleaned with the help of a hose with pressurized water and a brush, a high-pressure cleaner, etc. If the cement and mortar remains have set, they can be easily detached with a dry hammer blow.
