Full repair rarely passes without work on the alignment of the ceiling, which, by the way, are quite a challenge. To learn how to plaster a ceiling, we asked the professionals and we hasten to share with you.

As the plaster ceiling

Note! Alignment and plastering - they are two completely different processes, each of which requires a separate approach and selection of materials.

This article is devoted to plaster works using modern compositions based on gypsum binder. It describes the general principles of work, as some nuances, such as plaster ceiling gypsum board, require a separate and very detailed review.

surface preparation

Plaster must be applied to the previously prepared surface. This will ensure its longevity.

The sequence of works:

  • Using a metal spatula scraping finishing residues, old paint and putty, and if necessary, poorly adhering portions finishes.

Note! Purification of the concrete base may be carried out only by mechanical means. In no case can not be washed off the putty and whitewash, completely remove them in such a way does not work, and the remains after washing will prevent the adhesion primer.

  • After removing the old plaster, proceed to the application of the primer. The optimum is to apply a primer for smooth surfaces such as «Knauf Betokontakt" (the price - from 650 rubles.). The advantage due to the presence in its composition of quartz grains that form during polymerization sufficiently rough surface, the touch reminiscent of sandpaper.

Today, plaster walls and ceilings made of concrete often using exactly this primer.

Tip! When choosing a primer note the manufacturer and give preference to well-known, popular brands.

  • Once primed surface, leave it for 12 hours. It is better if the first coat will dry in a natural way, so give up the idea to speed up the process of polymerization by opening the windows or turning on the heater.

In this preparatory work, which includes our technology ceiling plaster over.

You can begin to plaster beacons.

The main stage

installation beacons

Instructions for installation of beacons with their hands:

  • With the help of the punch on the edges and the center of the drill holes for the screws.
  • The first hole we drill at a distance of 25-30 cm from the wall, the following - at a distance slightly less than the length of the rules. When using a standard two-meter rule for most of the rooms will need no more than three openings: one at the opposite wall, and one in the center of the room.
  • In each hole hammering plastic plug of appropriate diameter and fasten the screw.
  • Starting the formation of the tracks from the solution between beacons using the same type of plaster, which will be plastered surface. Laid track height slightly above the caps screws.
  • Once the track between beacon screws ready, we take apertured strip galvanized profile (6 mm) and applying it to the track. Using rules dent strip into the solution until the track until the profile strip abuts the cap screws.

    Exhibiting lighthouses on the level

  • The resulting beacon daubed solution for plastering on all sides, paying particular attention to filling the voids under the rack beacon. This point is very important because in the future when pulling the rules in place unfilled cavities cavity may be formed under the lighthouse.

The same technology fix all lighthouses. After installing them do a short break to "open" solution.

Note! Often masters advise after installing beacons to stop work for a day. During this time, there is a complete solution polymerization. On the one hand, it is justified as reduced risk of shifting or damage beacons in progress. On the other hand, in the contact mass with fresh frozen mixture formed beacon insufficient adhesion zone which adversely affect the strength, so it is recommended to work at a relatively fresh beacons, showing caution.

plastering

The first thing you need to decide - whether to use mesh. The need to use the grid depends on the layer thickness. When the layer thickness up to 15 mm mesh is used only for the sizing of joints between floor slabs.

plaster mesh

If the layer is at its thickest point is 30 mm, it is recommended to use a grid mark "strobe" from the cell of 5 mm.

The grid is fixed not on a concrete base, and in the thickness of the composition. Its main task - to ensure the strength of the layer.

For the plaster layer of more than 30 mm is more often used steel welded wire mesh galvanized iron. She prisverlivaetsya onto the base using self-tapping screws with special fixings. In contrast to plaster, welded mesh not only reinforces the plaster, but also enhances the quality of engagement with the concrete base.

Once we have decided on the grid, you can proceed to the preparation of the solution.

Optimal for such tasks as plaster ceiling with his hands is the use of a mixture of gypsum-based. Many positive recommendations received mix Knauf Rotband.

Preparation of solution:

  • The plastic container is poured 18 liters of pure water.
  • Using a spatula into water add about one kilogram dry mixture and thoroughly mixed.
  • Then add the remainder in the bag (30 kg) of dry mix. Using a drill with a special nozzle operating at low speed, knead the solution.
  • The stirred solution was set aside for 5 minutes, after time re-mix.

Note! In the process of applying either water or dry mixture was added to the solution can not be prepared!

Preparation of the solution

After the prepared solution for plaster can proceed directly to its application.

Application of the mixture:

  • A solution of lashes with a metal spatula or trowel, pre-wetted with water (since less plaster will stick to the tool). To start with plastering to a thickness slightly greater than the distance from the base of the ceiling to the beacons. Work is carried out, tightly clutching a grater to the surface.
  • After the first layer is applied, take the mesh roll, unwinding it and place it over the head. With the help of a spatula or trowel, we applied plaster is pressed against the mesh to the layer while unwinding roll along the lighthouses.

Note! When used for reinforcement of galvanized steel mesh, the first layer is applied directly on top of it. In this case, a grater should make a significant effort prodavlivaya composition through the grid cell and achieving its maximum contact with the substrate.

  • After the grid is fixed on top of the frozen layer is not plot the second layer, slightly higher levels of beacons.
  • In order to remove the excess, take a rule, handing it to the lighthouse and removing the excess.

The final stage is the removal of metal plates beacon. You can start to work after the plaster ceiling has dried up, but the plaster had not yet dried up. Furrow left on a place remote beacons embedded solution in one plane with the rest of the area.

For painting works can start after the complete drying of the plaster. Depending on conditions, this period can be from two to three days and a half weeks.

Summing up

As we mentioned at the beginning, all of the above - this is general advice on "how to plaster the ceiling." They are required to carry out, especially if you are first taken for repairs. In order to more accurately understand the technological and practical issues on our website provides detailed photo and video instruction, in which you will find the necessary information on the question.
