Quick verdict
A 700 watt corded gun with a hopper and a stainless screw that pushes mortar or grout through a round or flat nozzle into brick, block and paving joints, replacing the trowel and pointing iron for re-pointing a wall or grouting a flagstone patio. It fills joints far faster than hand pointing and the hopper and nozzle come apart for cleaning. Mortar consistency has to be right or it jams, and finishing the joints is still hand work. Documentation is thin.
Strengths
- Fills joints many times faster than a pointing trowel
- Round nozzle for brick and block, flat nozzle for wider paving joints
- Hopper and nozzle disassemble for cleaning
- Anti-release button keeps the nozzle locked under pressure
- Corded 700 W motor does not fade mid-job
Weaknesses
- Mortar must be mixed to a precise wet consistency or the screw jams
- Joint striking and cleanup remain manual
- Sparse instructions and variable quality control

Pointing Without the Trowel
Re-pointing a wall or grouting a flagstone patio by hand is slow: load the hawk, push mortar off the trowel into the joint, repeat for hours. A pointing gun pumps mortar from a hopper through a nozzle into the joint instead. CNCEST’s is a 700 watt corded gun with a stainless screw, a hopper and two nozzles, round for brick and block joints and flat for the wide gaps between paving slabs.
This review is based on the listing specifications and on how hopper-fed electric pointing guns perform generally. We have not used this gun ourselves and the brand is a generic importer.
How It Works
Fill the hopper with mortar mixed to a wet, smooth consistency, hold the nozzle in the joint and pull the trigger. The screw drives mortar out as you draw the gun along, filling the joint in one pass. The round nozzle suits 10 mm brick joints; the flat nozzle lays a wide bead for flagstones and slabs.
The Mix Is Everything
Pointing guns work with mortar wetter than a trowel wants, mixed with fine sand and free of grit. Too stiff and the screw labours and jams; too wet and the mortar slumps out of the joint. Owners of these guns describe the first batch as a learning exercise and the second as routine. Small test mixes save frustration.
Finishing
The gun fills. Once the mortar firms to thumb-dry, strike the joints with a pointing iron or jointer to compact and shape them, then brush the face. That part of the job does not change; what changes is that the filling, which was most of the time, is quick.
Cleaning
Mortar sets in the screw as surely as in the joint. Empty the hopper at every break, flush with water, and strip the nozzle and hopper for washing at the end. Treated that way the gun lasts; left for an hour with mortar inside, it does not.
Build and Support
At this price the quality control varies and the manual is thin. The anti-release button that locks the nozzle under pressure is a sensible feature. Buy from a seller with returns and test it on arrival.
Who Should Buy It
- Homeowners re-pointing a wall or garden brickwork.
- Anyone grouting a flagstone or slab patio with many wide joints.
- DIYers with a large job that would take days by hand.
Common Owner Complaints
Jamming and poor instructions. Mix wetter and finer; expect to learn by doing.
Alternatives to Consider
A manual mortar pointing gun with a plunger suits small repairs. A grout bag is the cheap option for a few joints. Professional pump systems handle whole buildings at far higher cost.
Verdict
For a big pointing or grouting job, this gun turns days of trowel work into hours, provided you master the mix and clean it religiously. It is a budget tool with a learning curve, and for a patio full of joints that curve is worth climbing.

Wetter than for a trowel, like thick porridge that just holds a peak, with fine sand and no stones. Too dry jams the screw; too wet runs out of the joint.
Owners of powered pointing guns describe filling a run of joints in a fraction of the time, with the saving largest on patios with many wide joints.
Yes. The gun fills; a pointing iron or jointer tools the mortar smooth and compact once it firms. Brush off the face when it is thumb-dry.
Empty the hopper, run water through, take the nozzle and hopper off and wash them before any mortar sets. Dried mortar in the screw is the end of the tool.
