The most common repair method is painting. It seems that could be easier? Staining has its secrets. Perfect ceiling has a uniform smooth coating, without streaks from the brush, stains and spots. In this article we will talk about how to avoid without stains using a water-based coating, acrylic, latex. Consider options using a roller and tassels.
Before using a water-based coating, the surface should be prepared. Regardless – painted your ceiling or whitewashed, if available cracks and bumps, and the old finishing material moves away from surface, then it must be completely removed. Defects and bumps need to be putty, sanded and primed. If it is about perfectly flat surface, then you just need to primer her. Before starting work, free the room from foreign objects and furniture.
If you need to remove the whitewash from the surface, then it should to wet. Brush small areas because surfaces dry quickly. If you wet it all at once, then you will have to do it many times, and this, you see, is superfluous waste of time and energy. So, wet the surface, wait, to whitewash accumulated moisture, removed the layer with a spatula. Thus, remove all whitewash from the surface.
If you have planned a facelift, start painting from the ceiling. Otherwise, it is likely that you bury the walls.
What if only the top is to be processed? In this case the walls need to be sealed with a film. The same measures need to be taken in regarding gender. To know how to apply the coating what temperature do this, read the recommendations manufacturer.
To paint evenly lay on the surface, it should be processed primer. It is better to buy the coating and primer of the same brand. If you have a flat and clean surface without spots, then it can be primed in one layer. In other cases, it’s better apply the composition in 2 layers. Then apply one coat to all dark places. This will prevent their occurrence after completion of work. After after priming, leave the surface to dry.
If the ceiling is ready for the next step, then assemble and prepare necessary tool for this. So you will need:
- roller, brush or spray gun;
- painting telescopic extension for the roller or ladder.
Choosing a method, it is necessary to take into account the features of latex paint. Below we consider its advantages and disadvantages.
If we talk about the benefits of latex coating, then their enough to give preference to this particular paintwork material:
- Washable coating removes wet contaminants a rag. Resistance to abrasion is not the highest. If you have to wash the surface frequently, it’s better to choose another composition.
- Such a coating creates a vapor barrier. The warmed ceiling from giproka after covering it with latex does not need additional vapor barrier.
- No odor during and after work completion.
- Dries quickly – from 20 minutes to 2 hours. It all depends on layer thickness and humidity in the room.
- Latex coating has good adhesion. Doesn’t peel off even from polished metal, with its preliminary primer.
Not yet in the world of materials made by man, not having disadvantages. It is therefore not surprising that latex paint is also not deprived of them:
- Under the influence of low temperatures, the coating may cracks, as a result of which it begins to exfoliate. Therefore its not should be used in rooms that are not heated or often ventilated in the winter season.
- Latex can become food for bacteria. On processed surfaces in a room with high humidity may mold is formed. But this only happens in very raw rooms in which the surface has not been previously treated antiseptic. Therefore, this disadvantage can be said indirect.
Water-dispersed acrylic paints give without exception matte surface. In contrast, latex coating is also glossy. The surface texture after coating can be judged by numbers on the packaging of the product. For example, Samtex20 is silky-gloss latex-based coating, and Samtex3 – matte.
If we talk about the features of a glossy latex surface, then they come down to the following:
- Gloss is less dirty, it is easier to wash.
- Glossy surface emphasizes defects, and matte – hides. Therefore, before coating with gloss, it should be leveled. surface.
- Gloss visually raises the ceiling due to partial reflection space under it. It creates an illusion of depth, which is very Actually in low rooms.
Preparatory processes come down to the fact that all exfoliated parts of the plaster and whitewash are cleaned off with a spatula.
If the entire surface or any part of it is affected by the fungus, then it must be treated with an antiseptic primer. And then apply it with a penetrating primer. Make it a brush because so that you can handle all potholes.
Then cover the defects. Best suited for these purposes. acrylic putty. To make the ceiling as flat as possible, use a wide spatula. After drying putty, sand bumps. Re-plastered surface areas primer.
A roller with a long pile should be used. Layers follows apply perpendicular to each other, with the final layer should be directed away from the window. This is done in one reception, otherwise along the border of the dried up areas will be bumps are visible. The roller should be rolled out on a paint tray or if it is not on a piece of cardboard.
Latex is an intermediate option between more persistent and expensive silicone and cheaper acrylic.
Acrylic based paints have high operational and physical and technical characteristics. Among their advantages is note the following:
- Environmental Safety.
- Vapor permeability.
- Affordable price.
- Easy to apply.
- No pungent odor.
- Practicality (it is easy to wash off dirt from a surface).
In the market you will find a large assortment of both domestic and and foreign manufacturer. There is plenty to choose from, but to say that paint from one manufacturer is very different from the same products of another – it makes no sense.
Acrylic can be applied to the surface in just 2 layers. It will be enough to hide all microcracks up to 1 mm wide. The resulting film will be quite flexible and strong.
In addition, in the market you can purchase highly specialized acrylic paints. It can be a surface coating agent. with traces of soot or greasy stains, etc.
When purchasing material, look not at its quantity in the container, but on the rate of consumption of the treated surface by 1 m2.

The nuances of painting
Surface preparation does not differ from that described above. therefore There is no need to describe this process again. After the final primers of the ceiling, you need to process the corners of the room with a brush, which should be dipped in the composition only half the pile. Wring out the paint and apply a strip of 3 to 5 cm wide in the corners. For the rest parts it is better to use a spray gun or a roller if the acquisition the first is impractical.
If you decide to use a roller, then you should consider some moments:
- Do not dip the entire roller in the material, as you can avoid smudges. Roll it around the tray. It will help you distribute composition on the roller evenly.
- Do not apply a thick and thick coating. Due to such Actions can form smudges and creases.
- Apply stripes along the room. Check for uniformity. Inspect it periodically from different angles and from different parties.
When working, you can not do drafts in the room. Temperature in it should also be as stable as possible. To find out the best temperature conditions, read the instructions for acrylic coating.
Application of paint on ceiling
It is impossible to process a surface at subzero temperature. If you want to save material consumption and achieve as much as possible uniform application, then you should use a spray gun. Such a purchase is advisable if you use this tool in future work.
Nowadays, you can often find color, not just white the ceilings. It is very modern, and besides the color surface brings some freshness to the interior. If you bought a finished product material with pigment, then there is nothing to worry about. However, if add color to the white coating, then prepare the mixture with a margin. This is due to the fact that when mixing the paint manually to achieve the same tone is unrealistic. If you feel like in a bucket the same color composition, then after drying, smears will be visible light or dark shade.
As a rule, it’s ideal to cover from the second or third times. But following the instructions in this article, you can to cope without the presence of additional experience. Most convenient the tool for work is a spray gun. However acquire perhaps for the sake of one operation, it’s not worth it. Unless you have free funds and you have plans to use this tool in the future.
When working with this tool the lowest material consumption, and the coating process does not require much physical effort.
Paint the ceiling with a brush is hard and long. Therefore, if you choose between the brush and the roller, it is better to give preference to the latter. FROM with it, the coating is uniformly applied, it needs to be wrong Dip often like a brush. So that the joints with the walls and corners are well processed they need to be pre-treated with a brush, without she can not do in the process of working with a roller.
Before working with the roller, draw a narrow line along perimeter of the surface, gently covering the joints. Do not dip whole roller into the material. Having dipped it a little, roll it into special paint bath. Thus material distributed over the entire surface. Starting from the far corner of the room cover the ceiling. Strips should be applied with an overlap of 5-8 cm. at the joints there should be no thickenings, but for this the composition is necessary rub with a roller over the surface.
Painting should be done at a fairly high pace, otherwise at stains will appear on the surface due to drying of the material. After its full coverage, let dry. Then apply a second layer.
The next coat should be applied perpendicular to the previous one. Thus, the possibility of the formation of stains and unwanted stripes.
In order not to emphasize the spots do not touch the allocated places. The quality of work is best evaluated from the floor, because being under the ceiling you will not succeed in doing this. Acrylic Technology material is no different from the technology of working with water emulsion.
After finishing work, avoid excess sun and drafts in indoors. You can ventilate it only after it has completely dried. surface, and this means – no earlier than a day.
Stretch Painting the ceiling
There is a desire to update the tension surface, improving such way its external performance by painting? It is worth noting that These manipulations can only be done with tension materials, without connecting seams.
For this kind of work, you should take a coating on acrylic basis. To apply the composition to the surface, use spray gun. Experts do not recommend covering stretch surfaces too often. The fact that they are with every next layer increase in weight, which means that over time sag, which of course is undesirable. The conclusion is simple – to cover tensioning structures can be no more than 5 times.
Experts do not recommend painting if you are missing any experience in this matter. This is due to the fact that even a professional is not able to maintain the gloss and gloss that he had material before processing. Having lost the gloss, the tension surfaces are larger attract dirt and dust, which becomes more noticeable.
It is also important to consider the fact that self-updated tension surfaces when using electric heating devices and when exposed to temperature changes, time will begin crack and will not be attractive. In such a situation, of course, you can re-treat the surface, but the result of this manipulation will be short-lived.
If due to some reasons, the tension structure has lost its attractiveness and needs restoration, then in quality alternatives can be partially decorated with airbrushing. You can make an imitation of the sky and clouds.
Combination of knowledge of coating technology along with quality priming and coloring compounds, and a working tool are the key to quality, reliable and beautiful coverage. If you have experience in coating, then share it with us and by our readers. Write comments at the end of this article.
