Nowadays, more and more people preferchoose painting as a decorative finish for the ceiling surface. This is quite justified, since the paint will hold up better than other coatings. In addition, for damp rooms, this is an ideal option, when you can avoid damage to the material in case of mold.
Ceiling painting technology.It is very important to be able to properly prepare the ceiling for painting with your own hands. If you want to do a major renovation, you must follow all the rules. Only then will the work not be so difficult, and the result will please you. If you do not follow the basic subtleties, even high-quality painting will not hold well.
Tools and materials for work
Preparing the ceiling for painting:a - cleaning from the solution with a scraper, b - smoothing with a flat surface, c - smoothing with a articulated float. Before proceeding to consider the main works that will need to be carried out, you need to understand what materials and tools are required for this. So, before you begin, you need to purchase:
- two spatulas - wide and narrow;
- a primer;
- starting and finishing shpaklevku;
- semifunctional;
- a wide brush;
- a soft rag;
- Cement mortar;
- sandpaper;
- respirator;
- drill or mixer;
- a hammer.
But the main material is putty.Therefore, its selection must be approached with special care. To choose a really high-quality putty, you should know its main features. So, the starting putty should be very thick - a little thicker than sour cream. And the finishing putty, on the contrary, should be rare. This is due to the fact that the first can be used to fill in defects, and the second should be applied in a thin layer. It is also important to pay attention to the marking. A good putty should have a protective hologram, which will protect you from buying a fake. As a rule, well-known manufacturers always take care of this. Also, the composition must meet all quality standards. Return to contents</a>
Surface preparation
Removing textured paint.First, you need to dismantle the old coating. The technology will depend entirely on the method used to finish the ceiling. If it was wallpaper or tiles, then you should simply remove them. If it is paint, then you need to remove it with a special remover, even if it has not yet begun to peel off. The most difficult thing will be with whitewash. As a rule, it is very difficult to remove. The most gentle method is to wash off the whitewash with ordinary warm water, to which a little iodine has been added. But in any case, this process requires protecting the walls and ceiling, otherwise you will have to wash these surfaces later as well. Then you should remove the old plaster and putty. First, tap the ceiling with a hammer. In those places where there will be a ringing sound, you should dismantle the old coating, not sparing it. And clean the remaining recesses from dust. Now you need to carefully seal all the defects. Pay special attention to the cracks. Before you putty them, you need to expand them. This is done by simply widening it with a screwdriver or spatula. Then cover it with mortar. This method will prevent the crack from widening further. It is advisable to apply a thin layer of putty over the mortar. When the main defects are corrected and the mortar and putty have set, the surface should be primed. It is best to use a primer that contains an antiseptic. This will help protect the surface from mold. It is better to apply the primer in several layers so that it is well absorbed into the surface. Return to contents</a>
Application of starting putty
After a day, you can begin the main stage of preparing the ceiling - treating it with starting putty.
Ceiling puttying scheme.As a rule, sealing cracks and holes with mortar does not allow you to achieve a perfectly smooth surface. And there is no point in covering up too small defects with mortar. For this reason, you need to use putty. Oddly enough, for better adhesion of the putty to the ceiling, experts advise using a thin nylon mesh that has visible identical holes. This will also prevent new cracks from appearing on the surface in the future. The starting putty should be thoroughly mixed before work. For this, it is advisable to use a drill or mixer - so the mixture will acquire the desired consistency. First, you need to take a narrow spatula and carefully cover up all the small defects and pores on the ceiling. Pay attention to the rust coming out of the reinforcement - it also needs to be covered up so that corrosion does not show through the paint in the future. When you do this, take a float and rub it vigorously over the entire ceiling. This will remove small nicks. Now you should wait about 2-3 days until the putty dries completely. And only after setting can you proceed to the main processing. Now take a wide spatula and apply a layer of putty that will hide all the irregularities and visible defects as much as possible. A good starting putty can be applied even in a thick layer. Just before that, apply a mesh that will securely fix this layer. Perform alignment immediately, without waiting for drying. Otherwise, it will be quite difficult for you to level everything later. After drying, you should inspect the surface. If the composition lays quite evenly, then you can not apply an additional layer of starting putty. But if the ceiling still requires alignment, then you should apply a second main layer. But it must be made much thinner. Do not neglect it if you see that the surface is uneven, since after painting it will be even more noticeable. In about two days, the surface should dry completely. Then you can sand it. To do this, first use a thin spatula, with which small lumps are removed, and then the ceiling is smoothed with sandpaper. But do not forget to protect your respiratory system, since there will be a lot of dust during the work. Return to the table of contents</a>
Finish putty and grout
Finishing puttying of the ceiling.The next step is to apply the finishing putty. Everything will be much simpler here, since you will no longer have to do careful alignment. As a rule, the finishing putty is applied in a very thin layer. And to achieve this, you will need to press the spatula hard. A spatula with an angled working part is ideal for this purpose. This way, stripes will not form on the ceiling. The finishing putty requires fast work. If you apply it very slowly, you simply will not be able to smooth everything out well. As a result, you will have to spend a lot of effort to remove the unevenness and stripes from the edges of the spatula. So, the treatment of the ceiling with putty is finished. Usually the surface dries completely after 10 hours. But it makes sense to wait longer so as not to spoil anything with another grinding. After drying, you need to remove all the unevenness with sandpaper again. Then you need to take a float and, slightly moistening it with warm water, do the grouting. After another day, you need to apply a layer of primer. It is needed so that the paint adheres well to the ceiling surface. And extra protection from mold formation will not hurt here either. After the primer has been absorbed, you can safely start painting. The order of work in the process of preparing the ceiling for painting is considered. It should be noted that during such work, it makes sense to protect the walls with polyethylene or masking tape, as is done for washing off whitewash, so that they do not get dirty with putty.</ ul>
