The development of technology, the emergence of new materials has not spared such an industry as construction. New types of building materials have significantly improved both the quality of houses being built and the attractiveness of the finish. This also applies to the material of walls, roofs, windows, insulation and fire safety, finishing materials.
Finishing work is now experiencing a real boom. Each year, new technologies and devices that improve the quality of finishes, new types of finishing materials. For example, instead of glue or cement, manually use glue - foam, which is in the cylinder under pressure, to glue the PVC tiles onto concrete pavements manually. Using a special gun, foam exits the nozzle and is evenly applied to the surface. The clutch is fast and high quality. Also, instead of putty knives, a gun is used to grout the joints in the decorative masonry between the stones, with which the joints are filled very quickly and efficiently.
Stone grouting gun
Of course, if you need to wipe the seams on the tiles on the working wall in the kitchen - it is not necessary to buy a gun for this purpose. An ordinary rubber spatula is enough.
Types of trowels for grouting With these spatulas, you can manually overwrite the seams of the house between the tiles. But if you trim the outer surfaces, for example, with artificial tiles under a torn stone, then traditional methods will not work. To do this, use a construction gun, which was invented specifically for such purposes. An ordinary culinary syringe was taken as a principle, but all taking into account the characteristics of the working mixture itself and the place of work. The gun for grouting stone joints has great productivity, which is very important with the brigade approach, which consists in the fact that one person prepares the joint, the other applies the solution, and the third finally cleans the joint.
Pistols come in two forms: for filling joints between stones and for grouting joints between ceramic tiles.
According to the device, the gun is:
- cylindrical body;
- nozzle, which is a cone with a long nose;
- piston - a plunger to squeeze out a solution;
- proper trigger device.
For example, this tool is POINTING GUN, an English manufacturer that will provide quality and ease of use.
The design of the gun for grouting stone joints Its features are:
- case with a nose, if you need to replace any component, it can be easily done;
- a piston, which is located between the washers, with which the flow of the mixture is regulated;
- feed mechanism with feed increase, so as not to spend much effort when working;
- driver cartridge, the company's own know-how with a long service life;
- a rod with a starting device, also with a long service life;
- all parts are galvanized;
- comfortable handles;
- steel welded frame, very durable and can withstand pressure;
- epoxy coating.
If the material is porous, not only as a stone, but also as artificial tile in the form of bricks and other similar materials, it is recommended to use the gun option to fill the joints between the stones.
Gun use
To begin with, the finished mixture is filled either with a spatula or other device into the cylinder body, then squeezed out using a piston into the seam. If the seam is horizontal, the strip is applied from left to right; if it is vertical, then it is applied from bottom to top. Also, with this gun you can fill in various unplanned voids and cavities.
Joint repair process Working with a gun is also convenient because it maintains cleanliness during operation; there is no need to clean the edges of the tile, as when working with a spatula.
But in some cases, the use of this device is impossible, for example, when laying directly with brick, not with brick tiles, clinker tiles, natural stone. This is due to the fact that the mixes for filling the joints between the tiles and between the bricks have a different composition and the latter, having sand in it, simply cannot be squeezed out through the gun.
Therefore, you need to know what grout and for what material is used. Basically for grouting use the same composition as the tile is glued. But special compositions are currently being developed for filling joints, and glue is recommended to be used only for gluing tiles.
The composition of the grouts have several types:
- made on a cement basis;
- made with the addition of epoxy resins;
- made with the addition of various latex plasticizers;
- made with silicone;
- made with rubber.
You can choose any, the only condition is that the mixture must be used within 40 minutes. Therefore, it is better to choose a dry mixture and prepare the composition immediately before use.
Before starting work, you must first clean the gaps and cracks between the different types of tiles, then moisten them with a spray gun, prepare a solution and fill the cylinder of the gun. And then get to work. And when the seam begins to harden, the seam begins to be embroidered using embroidery.
What to buy a gun for grouting stone
These syringes are produced by various companies, there are expensive, there are cheap tools. The main thing is that the equipment would be of high quality and the mixture would evenly exit through the nozzle, and not through the slots from the piston.
If this happens, this is not only an excess consumption of the mixture, but also poor-quality work and dirtying not only hands, but also material, especially if it is a rough surface. While it is clean, it will take a lot of time.
The choice of tools is not as great as it first seems.
If you consider the models, a good option would be STAYER Profi 0673-31, a German company, made in China. It is quite cheap, no more than 400 rubles, but judging by the reviews, it misses the grout a bit and you have to wear a bag on the piston.
You can see a gun for grouting stone at a price of 1,500 rubles
As a difference, you can see the syringe gun for grouting QUICK-MIX stone. The price of this gun for grouting stone seams is already 6100, but it is a tool for real professionals who value their reputation and their time. This is a Russian brand, but the quality of work speaks for itself.
Gun for grouting seams of a Russian company There is also a middle between them - POINTING GUN for 3300 rubles, the British manufacturer P.C.COX., And of excellent workmanship, convenient to use and you don’t need to put a lot of effort on the handle, where the system increases pressure with a mechanism. The instrument is warranted by the manufacturer. Moreover, they can also work with a solution to fill the joints between the bricks, which not every syringe does and to cut the joint along the nose with a cut. It is easy to fill and clean from the mixture.
You can see the gun for grouting stone joints at the price of 1300 rubles, also by the Russian manufacturer Euro Clinker.
Syringe - a gun from the Euro Clinker company VERY IMPORTANT!!! When applying grout, in the process of jointing, it is necessary to know and remember some features of this mixture: if there is no practice of using such products, then first it is better to work out the process on rejected finishing materials (panels, etc.), and it is better to start grouting the joints from the back of the building, from niches or openings, from places adjacent to the roof, which are not very striking in order to “fill your hand”.
Mixing the mixture.
Pure water is poured into the bucket (4.5-5.5 liters of water per 25 kg of grouted dry mix) at room temperature +15 to +20 ˚С and 2/3 bags are poured into the water. It is thoroughly mixed for 1 minute with a drill with a nozzle (400-600 rpm), after which the rest of the bag is poured out and mixed for 5 minutes. Then the grout is allowed to stand (breathe) for 2-5 minutes, it is necessary that all components enter into a reaction. In practice, the density of the solution should be such that, if you take a small amount of the closed mixture on your finger, then the ideal state is when the mass is very plastic, but does not drain (does not slip) from the finger. This must be worked out empirically.
Work with a solution.
The grouting gun is filled with a ready-made mortar (it is better to cut the nozzle of the gun by the width of the seam or 1-2 mm less) and apply it evenly, tightly to the seam, necessarily with a small influx, by 1-2 mm. Those. the grout should protrude from the seam with an even tubercle, 1-2 mm higher than the level of the tile, but at the same time not protrude onto the surface of the facing material - do not stain it. Depending on the time of year, weather conditions and ambient temperature, the SEAM WILL BE MASTERED JUST AFTER THE SOLUTION HAS PERMITTED IN THE SEA TO THE STATE OF WET SAND, from about 30-40 minutes to 2.5 hours (2.5 hours in early spring or late autumn) . In other words, this is a state where the grout mixture has almost given all the water to the tile, brick, etc., but has not yet begun to set. This can be determined by removing a small area of \u200b\u200b1-2 mm in depth by removing with a spatula or other object with a trowel aged for grouting. If the grout begins to crumble with wet grains of sand or small groups of grains of sand, then you can proceed to the jointing. If the solution still stretches, sticky, then we still have to wait.
- if the seam is rubbed in the traditional way, the mixture will be “smoothed out” and the dye will come out of it otherwise, which, when dried, will give a color change half a tone lighter and will not have a rough surface inherent to natural masonry. If this happened, then you can try to gently “comb” with a narrow brush of medium hardness the surface of the seam, without dirtying the final surface of the brick, tiles (especially when rubbing brick tiles, especially brick tiles with increased porosity);
- if you embroider a plastic mixture, the grout will just crawl, reach for the embroidery tool with all the ensuing consequences.
IMPORTANT!!! In no case should the grout be rubbed wet using a sponge! The dye is very strong, penetrates when grouting “wet” even in the glazed surface of the tile, leaving stains, not to mention porous materials. If it is necessary to achieve the effect of mashing the grout “under the face”, then after 40 minutes - 90 minutes, excess grout rising above the clinker tile is removed with a rubber or plastic spatula, as if removing chips. After that, we “whisk away” unnecessary residues, dust, individual pieces or grains of sand, without “excessive fanaticism”, i.e. Do not rub into the embroidered material (since the grains of sand in the solution were colored, if the zeal is too hard, the dye may stain the front surface). If it is necessary to achieve the effect of a semicircular recessed seam in the form of a "groove", then 1-2 mm is also removed from the surface, but with the help of a semicircular embroidery tool. After the seams are sewn up, all excess, crumbs and dust are brushed off with a not very hard brush (the brush-brush with a natural fluffy pile is not bad). There are other ways to embroider joints filled with mortar, it all depends on the creative approach to the embroidery process, the main thing to remember about the above!
If in some places the grout still got on the front surface, then on the glazed tiles these places can be treated with a strongly wrung rag. In the case of clinker materials or materials with increased porosity, it is necessary to wait for the dried seams to dry and after that you can gently scrape off the “dirty spots” with a drywall knife or other sharp object and then carefully “dust” the dust off the surfaces. To a greater extent, the implementation of these recommendations is necessary for the selected light tones of the grout in combination with the dark shades of brick or tile.
After jointing, the surface looks embossed in view of the large fraction of white quartz sand, natural stone with a fraction of 0.84 mm / 1.0 mm and impeccably sets off the beauty of clinker tiles on thermal panels, creating the impression of a building made of European clinker brick with colored mortar.

the COX Pointing Gun can be used to apply most bulk materials, although it is primarily intended to replace mortar in masonry and masonry joints.
In accordance with this functional purpose, it has two fundamental advantages compared to traditional trowel grouting methods:
- Greater productivity - especially with the brigade-integrated approach, including, for example, preparing the seam, preparing, and then applying the mortar.
- The dense filling of the seam from depth to surface ensures a high quality finish and virtually eliminates the possibility of voids and cracks.
- The result of this treatment is a strong and durable seam that is resistant to freeze / thaw cycles.
POINTING GUN The joint grout is placed in a plastic cylinder, one end of which is open, and the other has a tightly fitting nose.
This cylinder is placed in the frame of the gun, after which a rubber plunger is inserted into the open end, which feeds material from the cylinder.
The advantages of this gun, in the construction of which are used strong steel and aluminum, include:
- wear-resistant, durable lead-in chuck;
- high gear ratio 12: 1; Ergonomically designed handle and trigger arm shape that fits any hand size for long-term comfort.
NOTE: For this Cox gun, only fluid or fine grades containing rounded sand may be used — otherwise the materials will not flow freely under pressure.
- 1.Standard th cylindrical body with a tightly mounted conical nose \u003d replacement of accessories without high costs
- 2. A rubber plunger placed between steel washers \u003d the ability to adjust the optimal flow of material.
- 3. A high gear ratio of the feeding mechanism \u003d minimum efforts at work and reduction of fatigue.
- 4. Patented driver cartridge (made of sinter steel) \u003d high efficiency and long service life
