Probably everyone who has ever done an independent repair has faced the problem of uneven painting. It seems like he tried, carefully selected the tools and paint, prepared the base, and as a result - stains and stains, moreover, perfectly visible in bright daylight. Most of those who are faced with such an effect immediately come to mind the "saving" idea of applying a second layer. But, usually, such a decision is not the best solution. It will only get worse. Paint at least five times in a row, the effect will be the same. Stains and streaks will only become more noticeable. What is the reason and how to paint the ceiling without streaks correctly? Our advice will allow you to do this work efficiently.

Ceiling stains and streaks and how to prevent them

So, how to paint the ceiling correctly. This, like other types of work performed during the repair, has its own subtleties, so to speak, the secrets of painting. The negative effect can appear as a result of one mistake, or several at once. Having familiarized yourself with the main reasons for the appearance of stains on the ceiling, you will understand why this happened.

1. Reason one, thick paint

Viscous paint is much more difficult to distribute evenly than liquid paint. It is most important to thin it even before applying the base (first) coat. It is recommended by paint manufacturers to dilute them to a maximum of 10%. Although most often it is indicated on the cans that the paint is ready for use and does not need to be diluted. The buyer, of course, trusts what is written and, as a result, observes stains on his ceiling.

Hence the conclusion that the paint must be diluted with water. By the way, you can take more water than the manufacturer recommends, but not more than 20%. It is necessary to observe the consistency: the paint should not stretch like fresh honey, but gently drain from the roller. For the first pass, it is permissible for the consistency to be thinner, but on the second it is slightly thicker.

The main disadvantage of heavily diluted paint is that it will take more layers of paint to be applied, which will entail its consumption.

2. Slowness in work

When the painted areas dry too quickly, it is simply physically impossible to roll the boundaries between them. Therefore, in such places stripes appear. They become most noticeable after the surface has completely dried. So, it is advisable not to take breaks from work and roll out the paint evenly while the ceiling is wet.

It is imperative that the ceiling be primed evenly for even drying.

3. Roller with long pile

Smooth surfaces are best painted with a short nap roller. Otherwise, it will be difficult to avoid smudges, irregularities and other kinds of troubles. About which manufacturer of rollers is better and how to choose the hairiness of the roller can be found on the website.

4. Trite, but true

"Unpainted"? Didn't provide good lighting in the room to be painted? Do you have poor eyesight, and don't wear lenses or glasses? Then you just couldn't see where the unadorned areas remained. This happens quite often that more paint lays down in one place, and less in the other, because the roller is already dry without paint and is dry.

5. Wrong painting method

Do not paint in solid stripes. Most likely, there will be lines along the borders of these bands and they will not go anywhere. How to properly apply paint to the ceiling, consider the video below.

6. Poor foundation preparation

This is one of the most common reasons. Please note that the paint does not hide defects on the surface, but emphasizes them!

Therefore, if you want to get a smooth painted ceiling, then bring it to perfect condition. The correct preparation of the substrate, putty and sanding is the key to success.

Spots and glare on a painted ceiling and how to fix it

So, we found out the reasons. We hope that in the future we will be able to avoid most of them. However, what to do now, when the ceiling is already painted and all in terrible stripes, smudges, spots? How to bring it to the required condition?

Remained, perhaps, the only sure way out - grinding, that is, the ceiling must be skinned until the surface becomes a uniform tone and rough. Don't worry about a cloud of dirt and dust, there won't be a lot of them if you use grinders. After all, you only need to remove a small layer of paint. Choose a relatively small skin. Try to work very carefully so as not to get to the layer of putty.

After sanding is complete, the surface should be wiped with a damp cloth and inspected in good daylight. If the ceiling looks uniform and smooth, then you can start priming. If not, then it is better to use a finishing putty, applying it in a thin layer. Once dry, sand again lightly.

The next step is priming. It is important to purchase a high-quality primer for painting. And it is better to prime not once, but several times (at least two). After each time, you must wait for the surface to dry completely. Only after the ceiling acquires a perfect look, that is, it becomes even and smooth like a mirror, can you start working.

Do not forget: If the base has spots, streaks and irregularities, then all these "artifacts" will be visible even after the completion of the work! Therefore, before you start, make sure that your base is completely finished. Re-prime when in doubt

How to deal with ceiling stains from old leaks

These areas need special treatment. First, they must be thoroughly cleaned and washed, and then wait until they dry completely. Then subject to treatment with a biocidal solution. Use Fongimur for example. Do not wash off the product under any circumstances! Use a universal blocking primer immediately afterwards. It will help block stains from showing through putty and paint.

Tips on how to properly paint the ceiling without streaks

Achieve optimal lighting. The best result will be obtained with daytime. Then all the "unpainted" will be more noticeable.

1. For a good, streak-free paint job, try to ensure normal or high humidity. As practice shows, it is much easier to paint the ceiling with a roller without streaks in summer than in winter. In warm weather, the humidity level is much lower. Thanks to this, the paint dries faster, which does not allow it to roll out well over the entire area.
2. Good preparation is a must. Clean everything off the floor so as not to "wade" through the rubble. Excessive obstacles will take time, and you need to paint quickly. Therefore, professionals who know how to properly paint the ceiling prefer a roller with a long handle so as not to use a stepladder.
3. In order to prevent the appearance of stains on the ceiling, you need to work energetically and quickly!
4. The paint must be diluted with clean tap water until a very liquid consistency is reached.
5. Do not try to squeeze the roller intensively. The ribbed surface in the ditch does not serve for squeezing out, but to evenly distribute the paint over the coat. The roller must be constantly saturated, so you need to dip it more often.
6. Once you start painting the ceiling, do not press down on the roller with force. It is necessary to roll it, and not to press or rub it. This will allow you to paint the ceiling with a streak-free roller.
7. The paint should be applied in squares, not stripes. Especially when the area of the room is large. You need to work in zigzag movements to evenly distribute the paint over the sector. Also, you should not stay in one square for a long time. Still, after making a few movements, stop. After making sure that the entire surface of the painted area has been processed, move on to another square. The borders of the squares should be rolled out while wet. Work must be continuous and dynamic!
8. After applying the first coat of paint, carefully inspect the ceiling in good lighting. If there are unpainted places left, then you need to quickly, while the surface is wet, roll them. After the ceiling is dry, be sure to check the result again. If the paint does not fit well, then a second attempt can be made. However, if there are problems again, then you will have to start from the very beginning, that is, grind and prime several times.

It is important to know that any tint after drying will form new stains.

Note:

• Semi-gloss or glossy paints may not produce expected results. Matte is more preferable and does not leave clearly visible stains.
• On a snow-white ceiling, in contrast to a beige or cream one, any flaws are more noticeable. Therefore, if you are not sure of your abilities, then add a little color scheme to the paint.
• Remember that the larger the surface area, the more likely you are to get a questionable result. Therefore, you should not be surprised when the ceiling in a small bedroom came out like a painted one, and in a large living room you will not look at it without tears.
• The quality of the paint is also important. You can save money by purchasing wall paint, but buy the best for the ceiling! He is much more finicky.

Don't strive for the ideal. Painted surfaces are almost never perfect. The main thing is that in bright light, spots, stripes, streaks and smudges do not rush into the eyes. The ideal can only be achieved if you use all kinds of sprayers.
