No one is insured against cracks in the plasterboard ceiling, most often they appear at the joints of the floor slabs and the entire appearance of the structure suffers from this. Even experienced craftsmen cannot give one hundred percent guarantee that after creating a drywall ceiling, cracks will not appear over time. And the point here is not in the skill of the construction team, but in connection with the presence of many accompanying factors.
It is necessary to consider this issue more thoroughly, because every crack in the plasterboard ceiling causes significant excitement among the owners. The question arises: what to do, how to fix this problem? First of all, you should determine the reason for their appearance.
The causes of cracks
Cracks appear on the plasterboard ceiling for completely different reasons. Among the most common are the following.
The most common and common reason for the appearance of cracks on the ceiling is the subsidence of the structure. Unfortunately, here a person is powerless, because no one can stop this process, you just need to wait for its completion and not rush to erect drywall structures in a "fresh" building.
Plastered plasterboard ceiling
Any professional will say that in this situation, incorrect installation of the product is to blame. Most often, the problem arises in huge rooms where the laying is carried out from sheet to sheet, without using the offset of the seam. Then, even with small fluctuations in the structure, a crack may occur along the entire seam. For example, when driving along the road near a house of massive equipment.
As a rule, installation made with dowels and screws coming with them cannot withstand a lot of weight. Gradually, the owners begin to notice that cracks appear on the ceiling from the drywall. The bottom line is that the diameter of the screw in relation to the diameter of the dowel is too small and the walls of the dowel itself are very poorly attached in the hole. The result is a sag and a crack. In addition to suspensions, it is necessary to use rigid mountings with the ceiling.
Not primed ceiling
An equally common problem is the forgetfulness of masters or the lack of independent work. In the case when, before starting the putty stage, a person forgot to go through the primer. In almost ninety percent of cases, cracks will occur due to non-observance of ventilation and room humidity during repair work. The sheets absorb moisture and then dry out.
The main rule is that each layer should dry and then the next stages of work.
The main reasons have been identified, you can proceed to the second stage of studying the issue - methods of correcting and preventing repeated cracks.
Cardinal way of violation
The main violation of technology in the pursuit of material savings is that, according to Knauf standards, 2 layers of drywall sheets are used on the ceiling. The profile is fastened not with plastic dowels, but with metal nails or using a pneumatic gun to fasten the profile. More important tips for masters can be found in the article on the secrets of working with a file.
