We all probably encountered such a problem, as cracks in the ceiling. Cracks that occur between the concrete floor slabs, perhaps - a disease of Khrushchev, because at the time when five years have done for two years, "saving" in this half of building materials, such "trifles, " as some cracks out there, attention was not given.
Currently, many people ask themselves the question: "How to cement the cracks in the ceiling?" And often, many attempts to deal with this problem, give only a temporary result, and then cracks appear in all its glory.
Naturally, the best option would be a device drywall or stretch ceiling, which simultaneously smooths the ceiling, and saves (with proper installation) of such incidents as the crack. But, firstly, not all willing to pay a certain sum of money on false or suspended ceiling, and secondly, in rooms with low ceilings, a device of such a ceiling would make them even lower, at least - on the section thickness.
Therefore, the problem is repaired caused cracks in the ceiling becomes difficult to achieve for some, whose implementation is impossible.
The main mistake that, trying to still fix cracks on concrete ceiling - this is what they are trying to patch up by simply drawing on the ceiling of the next layer of putty. In order to solve the problem once and for all, and finally, seal the cracks, it is necessary to produce a series of works, and the first thing to do - it's completely clean expansion joints between floor slabs of lime or cement mortar, which they were at all times tried to patch up and wash the ceiling all the layers of whitewash, exposing the surface of the plate. Then - carefully primed the ceiling and the seams are deep penetrating primer, causing it roll and brush-ceiling brushes. After drying, the soil, the seams between the boards to seal the plaster, which is normally used for puttying joints of gypsum board (the firm KNAUF, this filler is called FUGENFULLER, but each manufacturer, there are its analogues). Not recommended for these purposes contour line, as its properties are radically different from those of the aforementioned fillers. Top seam, immediately after setting putty, you need to stick wide reinforcing mesh, using all the same FUGENFULLER, or contour line - and the seams are sealed!
Then you have a fairly laborious process putty ceiling. Technology putty ceiling is a consistent alignment of its less abrasive mixture. So, first you need to patch up a large pit, easily visible to the naked eye, and for puttying their use putty "START", "contour line, or their equivalent. After drying, the ceiling was ground abrasive mesh or sandpaper to remove irregularities arising from the ceiling in the putty. Further surface shpaklyuetsya less abrasive mixture "Finish" or "SATENGIPS, and again was ground abrasive.
If you want to achieve high quality, at this stage to pokleit ceiling interlining, which is glued with wallpaper paste for heavy wallcoverings.
Interlining creates an additional reinforcing layer, making the monolithic ceiling surface and smooth. Finally, the smallest bumps and grooves on the ceiling to seal the finish acrylic sealer like «PUTS», or finishing putty "Veton. After each layer of putty do not forget to prime the surface - this is an additional seal it and eliminate the dust that arises when grinding abrasive ceiling.
After that, you need only once primed the ceiling and paint it with a roller or spray.
If you follow the technology, the cracks in the ceiling so no longer appear, and the ceiling, at least visually - is straight.
