Suppose, with paint, we have already decided. But this is only half the battle. For the quality of the finishing layer is very important painting technology, as well as tools. In short, everything is in our hands!
To pick up everything that we do not recommend. Let’s approach the choice of tools thoughtfully and deliberately.
For painting large surfaces use rollers with removable fur coats. Between themselves, they differ in the length of the pile coat and the length of the handle. When choosing the first one, it should be assumed that the roller with a short nap is for smooth surfaces. Medium-length hair coats are attractive for wall holders with a slightly pronounced texture (for example, from drywall). “Long-haired” roller paint textured surface like a brickwork.
There are also rollers for various types of finishing paints: with a long pile for uneven or textured surfaces, with an average pile for matte paints, with a short pile for silk paints.
The length of the handle is selected based on from personal preference: the roller should be comfortable and not too heavy. However, if we are talking about painting inaccessible places, then the handle should be quite long. And for painting part of the wall behind the battery, the roller itself must also be quite compact: special tools “for radiators” are produced, which are also suitable, for example, to paint corners.
Do not get cheap rollers with a foamy structure: their spongy texture leads to the appearance of air bubbles, which, bursting, leave indentations on the freshly painted surface.
Painting small surfaces (the same baseboards) or applying decorative strips will require the use of another tool – a brush. For water-based paints, it is best to use a nylon polyester brush. The bristles absorb fluid, swell and deform, and nylon pushes water away and retains its shape. If a compound is used on a solvent, we recommend a brush with natural bristles: it will not leave marks on the surface, and the paint will lie smoother.
Cheap brushes have short and coarse bristles, and a wooden wedge is usually located in the middle. When working with such brushes the paint falls unevenly, and often there are bristles on the painted surface. In a high-quality brush, the bristles are thick, long, tapered, easily regains shape when bent. This brush paint can be applied evenly to the surface anywhere. Of course, high-quality bristle brushes are more expensive, but if they are well cared for and properly rinsed after use, they will last a long time.
For painting the edges and corners, it is better to use two brushes 150 mm and 50 mm in size, rather than a 200 mm brush, since it becomes very heavy with paint.
If you are constrained in the means, you can do with brushes of two sizes: large for painting walls and ceilings and small for painting edges and frames.
A 150 mm wide brush is used to apply the emulsion on flat surfaces such as walls and ceilings. The average flat brush of 50 mm is intended for flat surfaces or wooden products, such as plinths. A small flat brush of 25 mm – for the corners and edges of walls and ceilings, as well as for wooden products such as door frames. The small flat brush of 12 mm will be suitable for narrow places (eaves and socle levels). Finally, a small tint brush with wedge-shaped bristles is used to tint angles and narrow glass slats on doors and windows. For these purposes you can also use a brush with a size of 12 mm.
Before dipping a new brush into the paint, shake it to get rid of dust and loose bristles. Dip the brush in the paint by a third, and wipe off the excess paint on the edge of the can. Take it in your hand, like a ballpoint pen, and write whatever you want!
How long does it take to paint a room
If you think that painting takes a maximum of half an hour, and the walls become like new, we will have to disappoint you. Painting the surface is work that is not nuanced: the process can be delayed due to an incorrectly chosen paint, roller, or the wrong time to apply a layer. And the time of the day at which you pick up the instrument also matters. Training is, of course, the best way to achieve success, but we recommend avoiding other people’s mistakes – we tell you how.
Mistake number 1: painting unprepared walls
Minor defects, dust, grains of sand, lint from the brush during the previous painting may be under the paint and adversely affect the result. Under the paint layer all the flaws will be visible – it will remain either to accept, or to clean the wall and paint again. And possible grease stains will appear, how many layers would you cover the surface. Defects will be especially noticeable if you use gloss paint.
What to do: to avoid double work and unpleasant surprises, prepare the wall in advance. Take sandpaper or special plastering tools for sanding and walk through irregularities and defects. After – brush the dust with a brush or a broom. Stains can be removed by wiping the wall with a damp cloth and soap.
Error number 2: ignoring the primer
Do not use primer before painting walls? Do not be surprised if as a result you get an unevenly painted wall or an overrun of paint. The fact is that the primer provides a lower hygroscopicity of the surface, which saves means for painting. As well as the base gives “grip” to the surface of paint, which improves the painting of the walls.
What to do: choose the appropriate primer for walls. Brush it vertically with small stripes, and then horizontally – perpendicular to the first layer. After drying, the substrate can be coated with the first layer of paint.
Error number 3: improperly diluted paint
The paint is too thick consistency, or it becomes such in the process of work. Then it must be diluted – this is an intuitive action. But what to dilute is already a question that can spoil both the material and all the work. For example, if a water dispersion paint is diluted with white spirit, it will cause adhesion of polymers. If you paint the wall with such a composition, the result will be of poor quality – disappointment is inevitable: the paint will fall unevenly, maybe even lumps. If, on the contrary, the oil paint is diluted with water – it simply does not mix with the bulk.
What to do: read the composition on a can of paint and choose, respectively, the means with which to dilute the product. Do not pour in too much water or solvent – it is better to add a little, mixing the paint thoroughly.
Mistake number 4: painting without sample
The choice of color is a rather complicated process, especially if the shade have to be combined with another tone or pattern. Grief, a masterpiece will have to repaint, and so the process can be repeated to infinity. The same applies to the shade that you have to “get” with your own hands using color schemes.
What to do: add the coloring concentrate to the paint little by little, mixing the contents thoroughly. To begin with, pour a small amount of paint into a small container and add a few drops of color gauge – see what color it will turn out. Get the tone you need, and then do the same in a larger bank if you like the result. To make sure that the color is compatible with the overall decor of the room, try to do a vykras – put paint in a subtle corner and wait for it to dry. If the result suits you – for the cause.
Error number 5: the wrong choice of tool
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 evenly paint the wall, you need to purchase a couple of rollers and a brush. First, you will “roll up” the surface, and with a brush – 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 nap – 1–1.5 cm. It will pick up more paint, which will make it faster and easier to obtain a uniform coloring. For repainting, a roller with a short nap, 6–7 mm, will be more suitable: it will help to use paint more economically, and it will not leave any “stains”. Rely on a brush with natural bristles – it will not leave the lint on the surface.
Error number 6: applying paint “in different directions”
If you apply the paint vertically, then horizontally, and then completely, as you have to, in the hope that the wall will look decent when it dries – you make a serious mistake. All strokes can occur, especially if you wield a brush.
What to do: choose one painting option – vertical or horizontal – the paint will fall evenly and there will be no painting look ridiculous because of the chaotic strokes. When painting in several layers, you can alternate methods, for example, paint the first layer vertically, the second – horizontally.
Mistake number 7: applying paint in one layer
When applying paint in one layer, the coloring may turn out to be uneven, and if you want to change the surface color fundamentally, you will not be able to quickly finish the work. Even if you change the light shade to a darker shade, the first color will show through.
What to do: for an intense shade, apply two, and preferably three layers. The first will allow to distribute the paint on the surface; the second and third – it is better to shade it, even out the color and fill in small irregularities.
Mistake number 8: staining on wet paint
Of course, I want to finish painting faster and enjoy the result. Because often we do not think about the consequences of staining on the “wet” wall. As a result, the wet layer begins to tear off, stick to the brush or roller. Oil paint, in turn, can go bubbles – all the work will have to start again. However, waiting for the paint to dry, and polishing places with defects.
What to do: have patience. While the paint dries, do any other business. Pay attention to the instructions on the bank, which indicates how much time the paint is required for complete drying. If it is an emulsion on one basis, it will take a little time – and you will be able to start working again.
Mistake number 9: lack of paint
This can be a serious problem. Firstly, because during the trip to the store, an already applied layer can dry out (after drying, the joint between fresh and already applied paint will be noticeable). Secondly, it is difficult to find the right shade if you add 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” – tint the places where the paint will peel off over time. They always write on paint cans, on which area the volume is calculated – pay attention to the numbers. Keep in mind that if you paint the surface in two layers – the area is doubled.
Mistake number 10: the wrong timing for painting
Applying paint in bright sunlight is fraught with the fact that the composition will dry out too quickly – even before you distribute it evenly. Also the paint may start to foam or peel off. And if you carry out painting with the light of a light bulb, all errors will be barely distinguishable.
What to do: the best option for working on the surface painting is daytime, without direct sunlight falling into the window. It is better to paint the south side in the morning or in the evening when the sun is not so bright.
How much paint do i need to paint a room
We consider paint consumption on walls
As a rule, paint consumption on walls is calculated at the rate of 1 liter of paint per 5 square meters. Such calculations do not hurt to keep in memory, but they are very approximate and do not take into account the density of the paint, its opacity and the number of layers required.
In order to accurately calculate the required amount of paint for the walls, you need to know the perimeter of the room and the height of the wall. Multiply one by the other is not enough: from the resulting number, you need to take away the total area of all windows and doors. As a result, we obtain the surface area of the walls to be painted, and multiply it by the consumption of a specific paint indicated on the package.
For example, the length of the room (4 m) and the width (3 m) add and multiply by 2, we get 14 m – this is the perimeter. We multiply it by the height of the wall (2.5m * 14), we get 35 sq.m. – This is the area of all the walls with windows and ceilings. Since we will not paint them, we will take away their area (door 2 sq.m. + window 2.5 sq.m.), it turns out that we need to paint 30.5 sq.m. how paint consumption on the wall varies depending on its type
Depending on the paint, its consumption for the walls may vary. To cover 1 m2 wall you will need:
• paints for interior walls and ceilings – 120 ml,
• washable wall paint – 170 ml,
• paints for kitchens and bathrooms – 180 ml,
• latex paint for walls – 125 ml.
It should be remembered that the costs of paints depend on the preparedness of the wall, the material from which it is made, the absorbency of the base, texture (more for textured plasters and embossed wallpaper for painting) and even color (more for bright red, burgundy, yellow, orange and green shades). To reduce consumption, you can carefully priming the wall before painting, as well as applying a slightly diluted paint as the first layer, if the technology described in the instructions allows.
