No repairs may not be perfectwithout a smooth ceiling.For this reason, the problem of how to close up rusty ceiling concern to all owners of apartments in prefabricated houses built in Soviet times.Even joints that were sealed carefully, eventually diverge quite natural reasons - movements of the plates and the loss of the house.Rust on the ceiling of the place plate interface and perfect condition, it looks like a pretty neat groove width of 50mm with smooth oblique bevels.By the time the repair situation is required in reality is far from standard.In the best case, cracked and sometimes crumble out a solution, at worst - the difference plates, which requires balancing the entire flow.

Preparation and definition of the scope of work required with the ceiling

Any repairs rustication on the ceiling starts with preparation.Decorative coating is removed, whitewash and water-soluble paints blurred.Here are ways how to remove the old paint from the surface.

seam embroidered with a spatula.The crack extends, cleaned all the crumbling areas.If the solution is easily chipped off, you should remove it completely to the concrete, this you get rid of further peeling paint at the ceiling.

Before you seal the seams on the ceiling, carried out a visual inspection of damage and displacement measurement.In cases where the difference is not more than 5-7mm, and the crack width is small, it can be simply restored without further aligning all surfaces.If, however, a significant difference of 7-10mm, then after termination of Rust on the ceiling will have to pull a surface to neutralize the difference.A more significant defects, we recommend installing false ceilings.Align the big differences with the help of a solution is possible and some of the materials allow to apply a thick layer, but it will cost more.In this case, a much better use of the system or plasterboard ceilings.

The procedure works

competent repair rustication on the ceiling - a guarantee of cracks over the years.For work, we need:

  • primer that improves the adhesion of materials, it is best to contact the concrete-and its analogs;
  • fiberglass mesh (serpyanka);
  • steel trowel;
  • gypsum plaster mixture (Rotband, miners and others.);
  • with large slit width - foam.

Surface Rust Moisten the primer and wait until completely dry.When a large crack width carefully fill it with foam, so that it does not protrude below the ceiling surface and left for a day.Before you seal the crack in the ceiling, it is necessary to fill the plaster solution is ideal Rotband by about a third and pave serpyanku , so that the middle of the tape coincides with the center of Rust.Fiberglass tape will serve as reinforcement, it will protect from cracking, even with small motions of plates, which are inevitable in the future.

Then deepening Rust carefully filled with gypsum plaster and leveled.If there is a small difference, it is necessary to putty the entire surface area, which turned out higher.For alignment layer is convenient to use a steel rule.If you allow the experience of plastering work, you can use more convenient and easy wide spatula.

After drying, the whole plastered surface is leveled with a special grater or grinder.The further procedure depends on the method of work finishing.Also come to eliminate any defects.If you need to seal the hole, crack or peeling on the ceiling, they also need to clean, primed.For defects to use a large area glass fiber reinforcement or metal mesh plaster.

finishing seams

After drying restored rustication, you can begin to prepare for the final finish.If the difference was small, the whole surface ground penetrating solution.Then just shpaklyuyut finishing plaster mix (KNAUF, Volma and analogs thereof).After a thorough re-grout a ceiling primed.Now, the surface can be painted, covered with wallpaper.

If the difference was significant, the ceiling needs to be alignment.Minor irregularities can just gently pull a layer of plaster, making almost imperceptible unevenness.However, this method of solutions are not always suitable.In such cases, the complete leveling of the surface.This work is very time-consuming, require not only a lot of patience and diligence, but also the availability of convenient goats.If the total exceeds 5 mm layer of plaster, we recommend the use of lighthouses.

at differences in height more than 10mm all experts recommend the installation of a suspended ceiling, rusty but still must be sealed beforehand.The rational for this purpose to use assembly foam, since then they just close and neat appearance is not necessary.Then you can align the ceiling plasterboard structures or with tension systems.The resulting surface is perfectly flat.
