Leave or remove the beacons after wall plaster

Installing beacons is a crucial step in the plastering of walls. These guides serve as a benchmark for the thickness of the plaster, assisting in the maintenance of a level and smooth surface. But a frequent query is whether these beacons should be removed or left in situ once the plastering is finished. This choice may affect how your plastered walls turn out in the end and how long they last.

Plastering can be made easier by leaving the beacons in place, especially for inexperienced workers. By providing a strong guide, the beacons make it simpler to attain a consistent finish. There is no immediate need to remove the beacons because they are covered once the plaster hardens. But there are drawbacks to this approach, especially in terms of long-term wall upkeep.

Eliminating the beacons once the plaster has partially solidified can help avert future problems. Inconspicuous rust stains may eventually seep through the plaster as a result of beacons left inside the wall corroding over time. Furthermore, variations in temperature can cause the metal to expand and contract, which can cause fractures in the plaster. You can prevent these issues and guarantee a cleaner, more resilient finish by getting rid of them.

Beacon removal is a precise timing and technique operation. If the plaster is applied too soon, it may not hold its shape; if the plaster is applied too late, it may be challenging to fill in the spaces created by the beacons. A professional and long-lasting plaster finish can be achieved by carefully timing the removal of the beacons and the filling of the gaps.

What are used for

A simple device made of galvanized metal rails is lights for leveling walls. This tool has a profile that looks like the letter "t" when cut across. The procedure is carried out with reference to the profile’s upper face. The beach’s "leg" is made to firmly anchor itself to the work surface. The instrument is fixed firmly vertically against the wall.

Utilizing lighthouses helps to raise the standard of wall alignment. Using the rule, the mass is stretched with respect to the predetermined rails, producing a perfectly even coating. Their installation doesn’t require extensive knowledge of construction, which makes them convenient to use. There are four primary kinds of alignment racks that can be identified: corner beacons, plaster or cement lighthouses, metal bars, and metal pipes. Every species has advantages and disadvantages, and some are better than others.

Why remove lighthouses from plaster

In order to determine whether the beacons need to be removed from the wall following plastering, the following important considerations should be made:

• If the material from which the beacons are prone to the formation of rust, the pigment can break through the finish and spoil the appearance. Such a defect may appear due to the low quality of the material, too high humidity in the room, mechanical damage to the anti -corrosion layer during the installation of the beacons (the rule during alignment or sandpaper during grinding) or its complete absence. The manifestation of a characteristic color will not be long in coming if the final coating is made by wallpaper or a layer of paint is applied;
• Reiki can move away from the surface to be processed, which provoke detachments and cracks in the material. It will be deformed and disappear. Poor fastening of the rail on the wall can depend on the distance between the screws that fix it, the strong vibration of the walls or the shrinkage of the mixture of the plaster, accompanied by the loss of its properties;
• If you plan to install suspension furniture, fasteners can damage the strips, which will affect the quality of plaster coating. When touched the metal with a metal punch, vibration occurs, which is why cracks and detachment may appear.

Reiki can only damage the coating in hardened plaster; it has no beneficial qualities. The majority of seasoned plasterers lean toward the belief that beacons must be taken out after plastering. However, some people see benefits to leaving the rails anchored in the wall, such as significant savings on construction materials and temporary resources because plaster filling the holes created by the rails is not required.

In what cases do not remove the beacons

If the tile is completed, lighthouses can be left in plaster, preserving the stone or tile pattern. If the rust and pigmentation do not detract from the overall appearance of the work, lighthouses can be left in place after wall plastering.

If the profiles are constructed with high-quality materials and contemporary technologies, there is no need to remove the beacons after applying wall plaster.

Purchasing all repair materials from large chains of stores with the quality certificate attached is preferable. Avoiding a large rise in the room’s humidity if the lighthouses are to remain in the wall is advised. In order to prevent cutting into the metal when using a perforator or clogging nails, you can also make a note of where the rails are. Furthermore, the sliding rib profiles’ external parts may be coated with a metal-corrosion-preventing solution, but a definitive outcome following this process cannot be guaranteed.

Manufacturers of these compositions advise periodically updating the coating, which is not feasible for metal rails, and not all of these paints are safe to use in cement under conditions of total isolation.

If the rust and pigmentation do not detract from the overall appearance of the work, lighthouses can be left in place after wall plastering.

Removal technology

You must ascertain the degree of plaster hardening before removing the beacons after plastering. Plaster removal is the most straightforward method for removing beacons; if the coating has dried, additional techniques must be used. Should it be determined that pulling the beacons after plastering is necessary, you will need to buy the following tools:

• Passatigi;
• Chisel – steel tool (scraper) for working with plaster;
• Strenger or strong table;
• Magnet (if the walls are already plunged);
• Bright abrasive.

After plaster, lighthouse removal technology is nearly always the same. To minimize damage to the finished coating, get the beacons after plastering. Using a spatula, draw the material at the edges of the cut profile if it hasn’t frozen completely, and try to remove as much plaster as possible. The following day, the rails can be simply removed with a screwdriver by winding; the resulting holes are then filled with material and smoothed with sandpaper.

In the event that the choice to remove the rails was made after the plaster had fully set, the following algorithm is used to complete the task:

1. With the help of a magnet, the places from which the rails will be removed are determined. This stage can be skipped if, when marking on the ceiling of the room, marks corresponding to the location of the beacons are left.
2. Under the ceiling, using a chisel, the upper layer of plaster and putty is removed at the rack site.
3. With the help of a chisel, the upper edge of the profile is carefully bent. At this stage, the appearance of cracks in the wall should be avoided.
4. With the help of pliers, the rail is twisted and completely gets from the surface of the wall. Remove the beacons from the plaster with careful smooth movements, otherwise large defects or detachment of the material can form in the plaster layer.
5. Remove the beacons after plaster with small segments 10-15 cm long
6. The holes formed after the removal of the lighthouses after plaster in the walls must be removed – plastered with the same composition that was applied to the main part of the wall.

What to do with lighthouses later

Rails are typically only used once. The tool is not suitable for further use because you have to pull the beacons after plastering the walls with small segments that are 10-15 cm long. Small pieces can be reused by installing them on narrow sections of the wall, like above the doorway, provided they were removed without causing any mechanical damage or curvature.

There is a wide range of tools and materials available in many well-established networks of construction stores, including various types of corrective profiles for leveling walls. It turns out that installing and removing metal rails are not as difficult as it might seem at first. However, in order to perform competently, you must at least have a little experience working in the construction industry, read some theoretical material, and take careful note of pertinent details. You must create an action plan and choose the theses for each step before cleaning the beacons after plastering the walls. Then begin the practical portion with assurance.

So, should the beacons be taken down after plastering? The answer varies on the purported wall décor: if ornamental stone, tiles, or tiles are put in, the slats don’t need to be removed. The majority of skilled repairmen think that in order to prevent internal and external flaws in the work from appearing, lighthouses must be removed after plaster is applied to the walls.

Making the decision to keep or remove the beacons following wall plastering is crucial to guaranteeing a superior result. In order to achieve a uniform and smooth plaster surface, beacons are used as guides. But after plastering, their presence or absence can affect the wall’s longevity and appearance.

Plastering can be made easier by leaving the beacons in place, which act as constant reference points to guarantee uniform thickness. This approach can be more practical and faster, especially for inexperienced plasterers. But over time, beacons left in the wall may rust and cause unsightly marks and structural problems.

However, if the beacons are taken out after the plaster has dried, the finish may be neater and more polished. This procedure produces a seamless surface that is simpler to paint or wallpaper and removes the possibility of rust stains. Although filling in the gaps left by the beacons takes more time and effort, the outcome is usually more aesthetically pleasing and long-lasting.

In the end, the decision is based on the plasterer’s preferences as well as the particular needs of the project. It is generally advised to remove the beacons even though it will require more work in order to achieve a smooth and durable finish. It might be preferable to leave them in for a faster and easier process. Regardless of the approach selected, the best outcomes require careful planning and execution.

Knowing the effects beacon removal or removal will have on the final product and subsequent work is essential when making this decision. While leaving beacons in place can expedite the process and guarantee uniform thickness, over time it may result in uneven surfaces or rust. Even though it takes more work to remove them, doing so usually leaves a smoother, more durable finish that is simpler to paint or apply wallpaper to. In the end, the decision comes down to your priorities: speed and convenience vs upkeep and quality over the long run.
