Painting the walls with your own hands is quite possible. But the surface will turn out perfectly flat and attractive only if you choose the right and high-quality paint, use the necessary tools, and follow certain rules.
What paint to use?
The quality of the painting and the final result largely depend on which paint is used. There are several main varieties:
- Emulsion paints. The base and coloring pigments are in an aqueous medium and form an emulsion that is diluted but not soluble by water. Such coloring compositions are considered to be environmentally friendly and harmless, they form a uniform coating of the walls, they can form a rather dense layer on almost any surface, they are refractory, and also have very economical consumption. This group is divided into several subspecies. The first is water-dispersion paints containing water, which is the main thinner. They let in air and provide natural circulation of oxygen, withstand moisture and perfectly preserve tone. But here it is impossible to call them frost resistant. Acrylic paints are considered the most resistant, differ in elasticity and mask defects, repel water and do not allow steam. Latex formulations contain latex and because of this they are considered to be the most moisture resistant. They cover with a dense layer the most different surfaces, quickly dry. Polyvinyl acetate paints are safe, resistant to various influences, but are erased over time. Silicone paints are water resistant, but they also “breathe” well, they are able to close cracks and are highly elastic.
- The next group is alkyd compounds, the main components of which are resins. Such compositions are resistant to fading and water, non-toxic, suitable for different walls. There are two subspecies: enamel and oil paints. The latter contain a base of linseed oil, may eventually change shade and yellow, are considered toxic, and also dry for a long time. Enamel paints contain lacquer components, due to which they form a glossy attractive coating. Such compositions dry quickly and can be used both for exterior work and for interior work.
- Silicate coloring compositions are made on the basis of silicate substances, namely the so-called liquid glass, therefore, belong to the category of mineral. They can pass air, but at the same time withstand exposure to water, as well as temperature drops. But with other paints this type is not combined and therefore cannot be applied over old painted walls, and also serve as a basis.
- Glue paints have some characteristics of emulsion, but are less moisture resistant, therefore they are suitable for painting walls in dry rooms. Two subspecies are distinguished: dextrinized dyes and casein. The first are used for interior work and are susceptible to moisture, can break down with frequent contact with carbon dioxide and water. Casein formulations fit perfectly on almost any wall, are distinguished by increased durability and are suitable for finishing facades and various rooms.
What tools are needed?
For painting walls, you will need not only paint, but also tools used to apply it to surfaces. And for these purposes it is most convenient to use a roller, since it allows you to cover large areas, and also minimizes leakage and contamination. The surface of such a tool can be foam, fur or velor. The villi of fur often leave characteristic marks due to the structure of the pile. Velor roller is ideal for painting smooth walls. The foam coated tool absorbs paint and therefore simplifies the process somewhat. In addition, this option is appropriate if the walls have a porous structure and partially absorb the composition.
Painting narrow and inaccessible and angular areas will be more efficient and convenient if you use a brush. Bristles can have different lengths and stiffnesses, made of natural or synthetic materials. The choice of such a tool depends primarily on the paint used. So, if a water-based paint is used, then painting should be done with a synthetic brush, since the bristles will retain elasticity and stiffness without absorbing moisture. And if you decide to paint the walls with alkyd or oil paint, then choose a tool with natural bristles.
Coloring can be done with a spray gun, but this process is very complicated and laborious, so only a professional or at least a trained and competent person can cope with it. But the result will be excellent, as spraying will provide a perfect uniform coating of the walls.
Tip: it is most convenient to pour the paint into a container that has a compartment for a roller or brush. In addition, this capacity will allow you to use the required amount of paint, because the tool, if necessary, can be easily squeezed out without contaminating the floor.
How to prepare the walls?
To the surface of the walls after the coating paint was perfectly smooth, and the composition itself dried faster, you should pay attention to the preparatory stage. A full preparation for painting includes several steps:
- 1.If a repair is being carried out, the first step will be the removal of the old coating. It must be removed completely, since the remaining even small particles, firstly, will break the adhesion of paint to the surface of the wall, and secondly, create irregularities.
- 2.If there is a fungus on the surface of the walls, then it must be removed. Extensive mold formations can be mechanically treated, for example, wiped with sandpaper or scraped off. After that, you need to make treatment with a special fungicidal composition.
- 3. Next is the alignment of the walls, which can be done in two ways. The first is the use of putty. It will allow not only to create a flat surface, but also to eliminate the existing cracks. The second method is the use of drywall. Sheets can be mounted on a metal profile or fixed with the help of specialized glue.
- 4. Further walls need to be primed. The primer, firstly, will provide protection against fungi and other microorganisms, and secondly, will increase the adhesion of the surface to the paint.
- 5. And finally, painting, which will be discussed in more detail.
Painting may seem simple process, but in fact it has several nuances. So, at first it is best to paint over corners and hard-to-reach areas, since the paint usually dries longer in them. Next, proceed to full staining. Immerse the brush or roller in the composition, and then remove the excess, so that they do not pollute the floor and do not run down the wall. To make the coating quality, you can plentifully apply paint to a section of the wall, and then shade it. It is advisable to apply the composition in two layers, and the previous one should certainly be completely dry. And to avoid obvious stains, for the first time cover the wall horizontally, and the second - vertically.
It is better to paint the surface of the walls gradually, dividing it into several sections. In addition, the paint is also desirable to use parts, otherwise a large amount during prolonged contact with air may thicken, which will affect the quality of the application.
Painting can be not only classic with the use of a single shade, but also more original, if you apply interesting techniques. So, you can combine tones in different ways. The first is emphasis. By choosing a brighter or darker color that differs from the main one, you can focus on one wall or a separate part of it. The second option is a combination of two shades. So, you can divide the surface into two parts horizontally or vertically. The third way is to create wide or narrow bands of different tones. This technique will refresh the design of the walls and make it more multifaceted.
There are very unusual creative techniques. So, the use of a relief roller or stencil will allow you to create patterns. And if, making the repair of the room, you want to feel like a real artist and creator, then try to portray something abstract and exclusive. To do this, you can wrap the roller yourself with unnecessary rags, thereby creating a chaotic texture and unexpected prints. You can also try to achieve the effect of sand or the so-called "star dust". To do this, dip the brush in the paint and spray it on the surface of the walls.
Painting the walls is not only not very difficult, but also interesting and fascinating if you follow simple rules and show imagination using bold ideas.
