Overhaul is almost always accompanied by plastering of the enclosing structures. These works allow you to level the surface of the ceiling and walls for high-quality performance of further finishing work - painting or wallpapering. And to improve the quality of plastering, special guides are used, called beacons. They can be strings, metal strips, and even strips of solution drawn using a plumb line. At the same time, there are various ways of installing beacons and several types of mounts. And you should choose a specific option depending on the conditions for applying the materials - the level of surface smoothness, the slope of the walls and the financial capabilities of the customer.
Fasteners type "Kremmer"
The "kremmer" beacon mount is made in the form of a rectangular plate made of galvanized metal with holes for bending at the edges and a central slot for fastening. And the differences between this technology for installing beacons from others are in the following nuances:
- the possibility of bending and fixing fasteners on the beacons even without a special tool (the "cremmer" easily bends and presses down with your fingers) simplifies and speeds up their installation;
- with the help of "kremmer" beacons can be installed at a shorter distance from the base compared to other fixings, which saves a significant amount of plaster;
- fixtures can be used with any kind of fasteners (from self-tapping screws to dowel-nails) and guides (plastic, metal or made of plaster). In this case, the thinner the beacon, the smaller the distance between the mounts - so, for a 10-mm thickness, "kremmers" are placed about 30 cm from each other;
- the tension of the fasteners when installing the beacons under the plaster of the walls guarantees a more reliable fixation, after which you can immediately start finishing work;
- the position of the rail can be easily adjusted even after installation. By sliding the fasteners and turning it to the side, you can first open access to the fasteners, and then return the device back.
Method for installing beacons on the wall
One of the ways to set up beacons for plastering walls when using kremmer mounts is to do the following:
- Screw the screws into the base of the fasteners;
- Carry out the adjustment of the fastener caps along the levels;
- Center the fasteners along the guide with bending of their edges. The folds in the center of the "creams" should point outward;
- Press the beacon tightly to the cap and slide the fasteners onto the screws.
It should be noted that the mount must not bend along with the mount. Otherwise, the fixation may not be too reliable, and the beacons will move.
It is possible to speed up the work of securing the "kremmers" using a screwdriver rather than a screwdriver. In this case, set the device to a slow speed. And when correcting the position of an already installed guide, it is imperative to take into account the number of revolutions (screwdriver or screwdriver). To move, all screws must be unscrewed by the same amount. Details about the kremer mount.
Clips for lighthouses under plaster
Plastic fasteners-clips for KDM-2 lighthouses are used when performing rough plastering of enclosing structures (mainly ceilings and walls). Consisting of 2 parts (clamp and base), the structure is made of environmentally friendly polypropylene and allows you to install any version of the beacons (A-shaped, T-shaped, and others). The base of the clip is mounted on the screw head. In this case, the total thickness of the plaster layer must be at least 12 mm (6 mm of the beacon and the same amount of plaster).
Unlike beacons for plastering walls made of metal, which require a fairly large investment of time and appropriate temperature conditions, KDM-2 is much easier to install. Consumption of plaster is much less - on average about 24 kg per sq. m. And this means that fastenings of this type allow not only to mount beacons, but also to save material and time, increase the efficiency of plastering work, and result in a fairly flat surface without using a self-leveling mixture.
Correct installation of the guides on the clips
In order to install beacons for plastering walls, you should:
- Prepare a place for mounting the guides by drilling several six-millimeter holes for each (usually 5 or 6 holes) up to 6 cm deep;
- Insert dowels 6 x 30 into the prepared holes;
- Screw in screws with a length of 4.5 cm (or more if the plaster layer is thicker than the standard one);
- Using a fishing line and a building level, align the screw heads so that they are located in the same plane;
- Put plastic clips on the screws;
- Install the beacons in place, fixing with plugs.
The ability to move the already installed guides ensures maximum work accuracy. Whereas the absence of the need to strictly control their position also speeds up the installation. On average, fastening takes 3-4 times less time compared to other fastener options. And due to the minimum thickness of the plaster, even when renovating an ordinary apartment, you can save 2-3 cubic meters. m. plaster mix.

Mount "Ushastik" is a special model designed for more accurate and faster installation of plaster beacons used for finishing walls, floors or ceilings. And the main advantages of this product are the following:
- spend at least 3 minutes on the installation of each beacon;
- to increase the reliability of attaching the lighthouses to the wall, due to which the probability of their falling off when plastering a wall or ceiling is practically zero;
- start finishing work immediately after installing the guides;
- carry out work even in damp rooms. And, if for the usual mounting options it is desirable that the humidity does not exceed 65–70%, when using "Ushastik" its higher value is allowed;
- save about a third of the material.
The use of fasteners "Ushastik" increases labor productivity and allows you to quickly dismantle the guides and use them when performing other plastering work. And the performers do not need special training. Therefore, even an inexperienced specialist can install such mounts and mount guides on them.
Technology for installing guides on the "Ushastik" mounts
It is recommended to install such a mount for lighthouses under plaster on the walls, observing the following sequence of work:
- Prepare the wall using a level or plumb line to determine the vertical plane. As a result, the thickness of the plaster layer is minimal (no more than 10 mm), the material costs, and, therefore, the estimated cost, are lower;
- Drill the first 6mm hole from which the counting starts. It is advisable to choose for this a point located 20 cm to the left and 10 cm below the upper right corner of the structure;
- Insert the dowel and, using a chopping thread, make vertical markings;
- Make a markup in a horizontal direction;
- Mark and drill the same holes at a distance of 1–1.5 m from each other in the horizontal direction and about 400 mm in the vertical direction;
- Insert six millimeter dowels into them, screw in the screws with the fasteners put on and align the heads in one plane (using a plumb line or the same level).
The final stage of work is cutting the beacon profile exactly along the height of the wall and securing it. To do this, the beacon is applied to the surface and crimped with "Ears" using special round-nose pliers. After all the profiles have been installed, you can start plastering the wall - and, after finishing the work, remove the guides for reuse on another wall.

A rather rare variant of the lighthouse is the string one. Some experience is required for its installation. However, professional repairers who have mastered this technique are trying to mount beacons for string-type plaster when working with large surfaces - both due to the affordable cost and due to the increased speed. Using another option for walls of the same size, the construction team will spend several times more plaster and the guides themselves.
When using these types of fasteners for lighthouses, you only need 2 strings, installed in a few minutes. And to complete the work, you will need a small number of tools:
- plumb line;
- 2 strings (which can be replaced with cables or thin wire) and 4 dowels with bolts;
- plastering solution and 4 wooden blocks.
Installation rules for structures
In order to install fasteners for string-type plaster beacons, you will first need to drill 4 holes, stepping back 150-200 mm from each corner in the horizontal direction and a few centimeters in the vertical direction. The next step is driving in the dowels into which the bolts are screwed. When screwing in the fastener, leave about 10 mm of its length to twist the string.
The process of securing a string beacon consists in performing the following actions:
- Unwinding the string;
- Securing the beacon to one of the upper bolts;
- Pulling a string or wire using wooden blocks and screwing onto a second fastener;
- Repeat the same steps for the bottom bolts and the second rail.
After fixing both strings, their verticality is checked. And, in order to reduce the likelihood of their subsidence, a small amount of solution is thrown under each for installing beacons. Without this, the string may sag, and the section of the wall will have to be leveled again.
When performing work, string distortions should be avoided. Checking the beacon is done using a rule that should slide easily over the strings.
Further finishing should be started only after the solution has completely dried and the strings have been removed. You should also remove the dowels to which the beacons were attached. The traces remaining after the guides and fasteners are sealed with the same mixture immediately after the completion of the plastering work. Step-by-step instructions for attaching string beacons.
Installation of metal beacons
One of the most convenient and reliable ways to obtain a flat wall is to install metal beacons made from a galvanized perforated profile. Such products can withstand significant deformations and require a minimum of mortar. Moreover, special versions of the L- and T-shaped form allow you to install beacons not only on a flat area, but also in the corners of the room.
The rigidity of such guides is ensured by using metal with a thickness of 6-10 mm. The length of each lighthouse is 25 or 30 cm. And for their installation, use special plastic clamps, fixed with dowels.
How to fix metal beacons on the wall?
The process of aligning walls with metal beacons involves the following types of work:
- Verification of the vertical deflection of the enclosing structure and drawing lines for setting the guides;
- Preparation of a solution of a suitable consistency (it is allowed to add a small amount of gypsum, which allows the mixture to set faster);
- Applying plaster to the lighthouse, attaching it to the wall at a pre-marked place (on one side of the wall) and leveling;
- Additional fixing with a guide solution;
- Repeating the same steps for the lighthouse on the other side of the wall;
- Fixing intermediate guides, which must be in the same plane with the first two.
For more reliable fastening, self-tapping screws are chosen as fasteners for beacons under plaster. And it is advisable to align in one plane not with a plumb line, but using a water or even a laser level. Moreover, the verification of the correct geometry of the surface to be plastered should be carried out after the end of the work - using the same tools.
Plastering walls without beacons
In some cases, finishing work is carried out without installing plaster beacons. Using this method to plaster walls without using beacons is recommended only to experienced repairmen. Non-specialists will spend much more time on the same work and are unlikely to be able to achieve the same quality.
The decision to abandon the use of beacons for leveling walls is made after carefully checking each wall with a level or level. Too great distortions (more than 1.5 cm) in the horizontal or vertical direction may indicate the need to install the guides.
If the work is carried out not in a residential, but for example, in a utility room, where ideally smooth walls are not needed, you can consider the option of plastering without guides. Moreover, this reduces the consumption of plaster, and saves money (both on the material and on the lighthouses themselves).
Execution of works
Before plastering the walls with Rotband without guides, it is worth performing approximately the same preparation that is needed if you decide to install beacons under the plaster:
- Prepare all the necessary tools and materials;
- Clean the wall from dirt and exfoliated areas of the old finish;
- Mix the mortar by hand or using a mixer for mixing materials and when the mortar is ready begin plastering work.
To improve adhesion of the material to the walls, the walls should be primed. After that, plaster is thrown onto the surface - in vertical stripes wide. After filling the entire wall, the mixture is leveled with the rule, performing short zigzag movements from the bottom up. The remains of the solution are removed with a trowel. Next, an even bar or rule is set along the level and left for about an hour immersed in a gypsum solution. Then we remove the rule and get a straight vertical line. Further, in the same way, the following beacons are exhibited from the solution.
The disadvantage of this method is that it is difficult to level the wall without using metal beacons. And at the end of the main stage of work, it is difficult to get a flat surface. However, the method is good for professional builders.
When installing beacons for plastering, or performing work without these guides, you should know that, in addition to the correct technology, it is important to take into account other factors. These include the quality of the materials and tools used, which are not worth saving. And, of course, the experience of the performers - its absence can significantly increase the plastering time and significantly worsen the result.
