Painting walls: 10 mistakes

Painting walls: 10 mistakes you should know

If during the repair you have to paint the walls, take into account all the drawbacks of independent work, so that in the end it turns out that the surface is painted unevenly, and the paint has turned into a lump.

If you think that painting takes at most half an hour and the walls are like new, we have to disappoint you. Surface painting is a job that is not without its nuances: the process can be delayed due to a poorly applied paint, roller or poorly selected coating. And the time of day you pick up the instrument is also important. Training, of course, is the best way to achieve success, but we recommend avoiding other people's mistakes; we will tell you how.

Mistake 1: painting unsuspecting walls

Small defects, dust, grains of sand, fibers from the brush during the previous staining can appear under the paint and negatively affect the result. All defects will be visible under a layer of paint - it remains to either accept it or clean the wall and paint it again. And possible grease stains will show, no matter how many layers the surface covers. Defects will be especially noticeable if you use glossy paint.

What to do: To avoid double work and unpleasant surprises, prepare the wall in advance. Take sandpaper or a special plastering tool to sand and go over unevenness and imperfections. After – remove the dust with a brush or broom. Stains can be removed by wiping the wall with a damp cloth and soap.

Mistake 2: Ignore the primer

Don't you use a primer before painting your walls? Don't be surprised if you end up with an unevenly painted or overpainted wall. The fact is that the primer provides a lower hygroscopicity of the surface, which saves the means for coloring. And also the base gives "adhesion" of the surface to the paint, which improves the paint on the walls.

What to do: Choose a suitable wall primer. Brush vertically in small streaks and then horizontally perpendicular to the first layer. Once the base has dried, the surface can be covered with the first coat of paint.

Mistake 3: Improperly Diluted Paint

The paint is too thick or gets too thick in the process. So it needs to be diluted – this is an intuitive action. But what to dilute is already a question that can ruin both the material and the entire work. For example, if a water-based paint is diluted with white spirit, it will cause the polymers to stick together. If you paint a wall with such a composition, the result will be of poor quality; disappointment is inevitable: the paint will be uneven, maybe even lumpy. If, on the contrary, the oil paint is diluted with water, it simply will not mix with the mass.

What to do: read the composition of the paint can and choose the right agent to dilute the product. Do not add too much water or solvent, it is better to add little by little, stirring the paint well

Mistake 4: paint without sample

Choosing a color is a complicated process, especially if one shade needs to be paired with a different shade or pattern. The dueling masterpiece will need to be repainted, so the process can be repeated indefinitely. The same applies to the shade that you need to “get” with your own hands using the color scheme.

What to do: Add the coloring concentrate to the paint little by little, stirring the contents well. First, pour a small amount of paint into a small container and add a couple of drops of color; see what color you get. Get the shade you need, and then do the same thing in a larger jar if you like the result. To make sure that the color is compatible with the general decoration of the room, try painting: apply paint in an inconspicuous corner and wait until it dries. If you are satisfied with the result, get to work.

Error 5: wrong tool selection

Using the right brush or roller is just as important as choosing a paint. And it's not a matter of taste. In order to paint on the wall evenly, you need to buy a pair of rollers and a brush. First, he will “roll” the surface, and using a brush he will paint the corners and hard-to-reach places.

What to do: For the first layer of paint, it is better to choose a roller with a long pile – 1–1.5 cm. It will pick up more paint, making it quicker and easier to get an even color. For repainting, a short-haired roller (6–7 mm) is more suitable: it will help to use the paint more economically and will definitely not leave “streaks”. Opt for a brush with natural bristles: it won't leave lint on the surface.

Mistake 6: Applying paint “in different directions”

If you apply the paint vertically, then horizontally, then all the way as needed, hoping the wall will look decent when it dries, you're making a serious mistake. All strokes may appear, especially if you are using a brush.

What to do: choose a paint option, vertical or horizontal, the paint will lay down evenly and the paint won't look ridiculous because of the strokes 

Mistake 7: Apply paint on one layer

When applying paint in one layer, the stain can turn out to be uneven, and if you want to drastically change the color of the surface, then you definitely will not be able to finish the job quickly. Even if you change from a lighter shade to a darker shade, the first color will show through.

It's chaotic. When painting on multiple layers, you can alternate methods, for example painting the first layer vertically and the second layer horizontally.

What to do: For an intense tone, apply two, preferably three coats. The first will allow you to distribute the paint on the surface; the second and third - it is better to shade it, to match the color and fill in small irregularities.

Mistake 8: Painting over wet paint

Of course, I want to finish painting faster and enjoy the result. Therefore, we often do not think about the consequences of painting on a "wet" wall. As a result, the wet layer begins to peel off and stick to a brush or roller. Oil paint, in turn, can form bubbles; all work will have to start over. True, after waiting for the paint to dry and polishing the places with defects.

What to do: Be patient. While the paint dries, do anything else. Pay attention to the instructions on the can, which indicate how long it takes for the paint to dry completely. If it's an emulsion in a base, it won't be long before you can get back to work.

Error 9: lack of paint

This can be a serious problem. Firstly, because during the trip to the store, the already applied layer can dry out (after drying, the joint between the fresh paint and the already applied one will be noticeable). Secondly, it is difficult to find the right shade if you added color to the paint yourself.

What to do: The easiest option is to take more. In extreme cases, an unopened can can be returned to the store or left “just in case” – touch up places where the paint will flake off over time. On the paint cans, they always write what area the volume is designed for; pay attention to the numbers. Note that if you paint the surface in two layers, the area will be doubled.

Mistake 10: Wrong time to paint

Applying paint in sunlight can cause the composition to dry too quickly, even before it is evenly distributed. Also, the paint may start to foam or peel off. And if you paint under the light of an electric bulb, all the mistakes will be barely distinguishable.

What to do: The best option to paint the surface is during the day, without direct sunlight coming through the window. It is better to paint the south side in the morning or in the evening, when the sun is not so bright.
