If you are thinking about how to plaster ceilings made of drywall, then you probably want to get a quality result. This process does not require any special skills, but still must be carried out using a certain technology.
Preparatory work
Despite the fact that the drywall has a smooth surface, its base needs some preparation. At this stage, it is important to analyze how correctly the screws are installed. This process involves checking whether the fasteners are fully tightened. Sometimes it happens that the master only grabs the sheet, forgetting to firmly install the self-tapping screw in its place. As a result, after plastering, sheets of drywall shrink and peel off a little from the base. The composition, applied to drywall, eventually begins to change the initial linear dimensions and becomes covered with cracks.
Before plastering ceilings, it is necessary to clean all existing joints from dust, cover them with a primer and putty, which, as a rule, is a special adhesive composition. In addition, the seams should be further strengthened, for which it is recommended to use a reinforcing mesh. This will eliminate the likelihood of cracks on the surface. After applying all the compositions, each layer of which takes time to dry, it is necessary to process the joints, which involves the use of a tungsten-based grout mesh. You can replace it with a spatula. Both of these tools should allow you to get rid of the excess amount of previously applied compounds from the plane of the seams. At the final stage of preparation of the surface of the blade should be well primed. Now we can assume that the work on the preparation of the foundation is completed.
The choice of method of work
Before plastering ceilings made of gypsum plaster, you should choose a technology for the work. Some craftsmen apply the finishing mixture, which is sold dry in bags. You can also purchase a finished composition, which before applying will not need to be kneading, since it is offered for sale in buckets. In this case, you have to use acrylic material. The second option requires the initial application of the starting mixture. And only after it has completely dried - the finish. If you still have not decided how to plaster the ceilings, then it is worth considering the advantage of the first described option, this procedure makes it possible to complete the work in a much shorter time. However, there is also a minus, which consists in the fact that almost any finishing mixture is unacceptable to be applied with a layer whose thickness exceeds 3 mm. With a ceiling that does not have a perfectly flat surface, it will not be possible to hide errors, as a result, it will not look as we would like. If you do not want to lose time and effort, then you should initially analyze the evenness of the ceiling surface and only then choose the technology for the work.
Features of the technology of applying plaster
Before plastering the ceiling, it is worth considering that the second option will undoubtedly take a more impressive amount of time, however, the quality of processing the base will turn out to be excellent. This is due to the fact that the starting mixture of a significant fraction will allow you to hide all the errors of the plane. And only when the ceiling will have perfect evenness, it will be possible to apply the finishing mixture on its surface.
The need for alignment
Before plastering the ceiling, many home masters think about the question of whether it is worth doing such work. It should be noted that a base with irregularities will look bad in any light. Shadow areas will appear, and the bumps will be clearly visible. In addition, a layer of mortar will protect the surface of the drywall from the negative effects of high humidity or temperature changes. Such phenomena, it should be recognized, are characteristic of premises of any purpose. If you still cannot decide whether to ceiling the plaster, then it is worth considering that after such a repair it will look attractive for a long period of time until you decide to renew it again.
Tools and materials
Do not forget about the additional equipment that will be needed during the work, because if you do not prepare thoroughly, the work will go slowly and will be accompanied by large labor costs. Thus, the first thing you need to take care of is the stepladder. Professionals advise using compact forests. This recommendation is due to the fact that the mixture will have to be dialed on the instrument every now and then, because it is unlikely that the container with the composition can fit on the stepladder.
From small tools and supplies it will be necessary to prepare a capacious bucket made of plastic, or a special container. You will also need spatulas, the width of one of which is 10, the other - 30 cm. In order to mix the mixture more quickly, you need a drill, which has a special nozzle in the form of a mixer. For safety reasons, it is recommended to use glasses, as well as a respirator and gloves.
Additional equipment
When deciding whether to plaster the ceiling or choose a stretch option, it is worth considering that the first will cost much cheaper, and for its implementation it will be necessary to prepare:
- primer;
- putty;
- reinforcing mesh;
- wide brush;
- tungsten mesh for grouting.
Preparation of the starting mixture
If you are interested in the question of how to plaster the ceiling correctly, then you should know how to apply the starting composition. Initially, it must be diluted. To do this, the container should be filled 1/3 of the liquid in which to put the plaster. Next comes the drill, which has a mixer nozzle. Using this tool will allow you to mix the composition well. If the need arises, then water should be added to the mixture, this will make it more liquid and plastic with a thick composition. In order to check whether the composition is ready, it should be typed on a spatula: it should not drain off the tool, but, on the contrary, should be well kept on its steel surface.
If you have a question about how to plaster the ceiling correctly, then you should know that after preparation the composition must be well infused, for this it is left after kneading for 5-10 minutes, after which the mass must be thoroughly mixed again. With this approach, small particles can absorb moisture and gain plasticity.
Plastering
Gathering the composition on the instrument, it is necessary to take as a basis the movement that is characteristic of a person who spreads butter on a piece of bread. When applying plaster to the base of the ceiling, do not try to rid the surface of all stains, since such a skill is subject only to a professional. It is not necessary to think that errors will remain on the surface, they can be eliminated after the ceiling dries. This can be done by means of a trowel.
It is important to remember that initially it is recommended to eliminate obvious errors, whereas after that the master should start processing the entire remaining area of the ceiling. As soon as the entire surface of the ceiling is finished, we can assume that you have dealt with this stage of the work, you can leave the base until it dries completely.
Final work
If you are considering the question of how to plaster the ceiling with your own hands, then you should definitely know what work should be done after applying the first leveling layer. A putty knife comes into play, with the edge of the working surface of this tool, it is necessary to rid the surface of quite impressive stains and an excess amount of composition. If you notice less significant defects, and they will definitely be, then they can be processed using a grout grid. In the presence of impressive depressions after carrying out the described works, the problem areas should be covered with a primer. After these areas are again treated with starting plaster and sanded again, but, of course, after completion of the process of complete drying. Once the base is completely dry, you can again grout and apply the primer.
Application of finishing plaster
If you choose to apply only one layer of plaster, then you will be faced with the question of how to plaster the ceiling with your own hands using the finishing composition. It, as described above, can be applied to the first plaster layer. This must be done after the soil has dried. This stage should be started with a kneading of the final mixture, while using the same proportion as in the case with the starting composition. After the finish layer has been applied and dried, it will also have to be wiped off, all errors in error should be eliminated, if any, only then the surface should be primed again.
Before plastering a gypsum plasterboard ceiling, it is necessary to consider what finishing decorative coating will be used, since it will be applied after the soil has dried. It can be, for example, paint, or wallpaper. The ceiling treated in the manner described above will have excellent adhesion, this indicates that all materials will adhere well to it. In order to obtain the expected result, the period between the application of each subsequent layer should be maintained.
Recommendations for work
Before plastering the ceiling for painting, it is necessary to complete all work that could cause surface vibrations. Otherwise, the procedures performed will be futile. If the work is supposed to be carried out in a room that is characterized by high humidity, then it is worth choosing drywall with moisture-resistant characteristics. During operation, such a ceiling can be vacuumed and wet-cleaned, such surface effects will not bring harm.
If you are thinking about how to plaster the ceiling in the bathroom, then you need to choose a composition made not on gypsum, but on a cement basis. Observing all the rules of the work, you will get an excellent result.
