How to paint water-based wall paint

In order to know to to to build water-based with wall paint, it is necessary to get acquainted not only with technology of its application, but also with the preparation procedure for of decorated surfaces. If is strictly followed by all rules, then it is possible to verify on its example that there is nothing super complicated in this process.

wall Despite the for the appearance on the market of numerous innovative finishing materials, the walls were painted and the remains most relevant for modern office spaces and for living rooms in apartments and private houses.

Water-based paint is attractive in that it produces on water-based and not produces an unpleasant odor when painting. At the same time, it is distinguished by excellent decorative properties - as a result of dyeing a pleasant soft matte texture of the surface is obtained. In addition, with the help of this type of paint, you can create different patterns on the walls that mimic the relief, or you can create a special

texture of using auxiliary elements. Usually this method is used when the wall has irregularities, and there is no way to fix it. Ideal even painting is obtained if the wall is well cleaned and leveled, so all work begins with the preparation of the walls.

Before the can start any painting related work, it is necessary to prepare the work space, as well as the tools and accessories, including the protective tools.

Tools and materials for use

For the work you need to prepare the following tools:

• Building mixer, but in this case may well suffice for a conventional drill with mixing nozzle. This will be enough to mix the paint.

• Paint tray - for easy dipping of the roller in paint and for maximum material savings.

• Pile with pile medium of length and with long handle - for easy wall painting under the ceiling without using additional ladders or goats .

• Brushes of different widths - for applying paint in places inaccessible to the roller.

• Grater for cleaning walls from old coating and carrying them grinding.
• Spatulas, brushes or rigid sponge - for cleaning surfaces.
• Wide trowel for leveling walls with putty.

• If the paint is applied either by a relief pattern or by imitation, additional tools or self-made elements will be needed to help create the desired texture.

Painting materials for walls

Pre-prepared and materials that can not be avoided when painting:

• Water-based paint. It can directly have an defined color or be white. In the latter case, a dye will be needed that will allow you to select the necessary shade of to the .It is recommended to make mixing by yourself, as it becomes possible to paint the walls in slightly different tone. For example, the walls in which the window blocks are installed illuminate the less than the other surfaces in the room, so they can prepare the paint for a lighter tone.

• The dye of the chosen color.

• Primer for walls, which will prevent the occurrence of mold stains on the walls and create conditions for good adhesion of the paint to the surfaces.
• Sandpaper for cleaning and polishing the surface.
• Putty, rough - for repair and finishing - for final leveling of walls.
• Polyethylene film - for the protection of surfaces that will not be painted, from accidental drops of paint.

• Painting tape-tape, to fix the protective film on walls and floors, to protect staining areas - if necessary.
• In addition, needs to prepare work clothes and skin and respiratory protection - is a suitable suit, respirator or mask, rubber and fabric gloves.

On the choice of paint, and is more accurate , on those criteria that it predetermines when buying, you should stop several more.

Paint choice parameters

Water-emulsion and water-dispersion paints are, perhaps, the best option for decorative painting of walls and ceilings in living areas. This is due to a number of positive qualities of similar compositions:

• Similar paint - is an environmentally friendly product that does not harm human health.
• When working with these paints there is no sharp unpleasant odor in the room, so work can be done even with closed windows.
• Water-emulsion compounds give a flat matte surface - opens wide space for the implementation of a wide variety of design projects.
• The high enough moisture permeability of the paint allows the to be used by its for decorating walls in rooms with high humidity if the surface is prepared correctly.

The most popular water emulsions, which are made with the use of acrylic resins. They provide the paint with maximum elasticity and strength, but such compositions have a rather significant cost. Therefore, it is possible to choose compositions that are affordable, but also include the acrylic components - is vinylacrylic and styrene acrylic paints.

If the paint is latex, the surface will become water repellent after drying. This coating can withstand about a thousand washing cycles.

The water-dispersion variant nt cr asci differs somewhat from the aqueous emulsion. This primarily concerns the main constituents to which the styrene copolymers, polyacrylates , and polyvinyl acetates belong. These component substances do not dissolve in water. When the paint is applied to the surface with , drying evaporates the water, and polymerization of insoluble components takes place on the wall to form the coloring film.

Pigments are included in both aqueous paints - in this capacity, titanium dioxide or zinc oxide - is used to make them ideally white. In the inexpensive formulations paints instead of these coloring pigments is added a chalky component, which, in addition, fulfills the function of the filler.

Buying coloring compounds, you need to pay attention to their characteristics, such as drying time, viscosity of the emulsion, its consumption, shelf life, storage conditions, specific gravity and others.

• Drying time applied paint is from 2.5 to 24 hours, and this depends on the humidity and temperature in the room. The ideal conditions for conducting painting jobs: the temperature of the painted surfaces is + 18 ÷ 20 degrees, the relative humidity is -60 - 65%.
• Viscosity of - is an indicator of the degree of dilution with water. A similar parameter is measured with a viscometer. The simplest viscomete is a funnel strictly of a particular volume with a calibrated drain hole. A viscosity index is measured in seconds - for how long all the paint will flow out completely. Such a device is often available to professional painters, good, it is inexpensive. But data on the viscosity of the composition must be indicated on the packaging. Usually, the viscosity of 45 - 50 s is required for paint application with a roller or brush, and with for spraying - is not higher than 20 - 25 s.
• The paint consumption per one square meter of tri area covered in one layer is 170 ÷ 200 ml. This parameter depends on the surface on which the - paint is applied with its looseness and absorbability .
• The expiration date of water-based paint is almost always two years from the release date, under the conditions of the correct of its storage. These conditions include the room temperature, which should not be negative, but also the overheating of the paint should not be allowed. - the paint should be stored in a cool room with a flat temperature
• The specific gravity of one liter of paint is approximately 1.3 kg.

The main technical characteristics of water emulsions, established by GOST, are given in the following table.

Water-based formulations are easily applied to the prepared surface, but they can not be painted with walls covered with an oil-based paint, or a glossy surface. On the same walls, previously covered with water emulsion, will lay paint, made on any basis.

Water-based paint can , in principle, be applied on to any surface, except for metal, as it can provoke corrosion processes.

Surface preparation

Since almost never the surface of the walls is perfectly flat, and also , most often it already has some old coating, it in the first placeit is necessary to bring to a proper state appropriate for painting.

Before beginning work on floors and other surfaces that will not be cleaned and painted, the plastic film is spread. Its needs to be fixed to the skirting boards with the help of paint tape. Applying such a method of protection, you can later rid yourself of t t with mine-cleaning and keep in its original state the decorative floor covering.

Cleaning the walls

• First you need to remove the old decorative coating from the walls. This process can be carried out using rigid brushes or sponge, if the wall, for example, was covered with whitewash.

The surface is damped with water, the whitewash residues are scraped off with spatulas, brushes , and if it is easily soaked, then its is simply washed off using a sponge and a soft cloth.

• If same surface is painted with oil paint, then its can be cleaned using a construction hair dryer - is a long and time-consuming process, especially, if the wall is painted with a thin layer. You can go in other ways, for example, in such a situation there are two exits - to cover the walls with gypsum board, or make them incised and re-plastered, creating a smooth surface.

If there are a lot of layers of paint on the wall and it started to depart in some places, will have to clean of its , heating with a hair dryer and picking up with a spatula or scraper.

Filling the slots

• After cleaning the walls, it is necessary to conduct the most thorough inspection of them for cracks or unstable areas. If they are not sealed before puttying and painting, they will definitely appear on the already updated wall.

• The detected cracks should be widened so that the repair staff penetrates as deeply as possible into the wall thickness.

• Cracks are widened with a spatula or grinders with a circle around the stone. Then they are thoroughly cleaned, covered with a deep penetration primer and allowed to dry on the specified by the instruction time( usually - from 4 to 6 hours).
• After drying, the crevices are sealed with a putty or one of the polymeric materials, for example, silicone sealant or "liquid nails".
• Completing the slots, it is necessary to try to remove the from the surface of the wall all the surplus material, so that the "patch" is level with the wall surface.
• After complete drying of the repair composition, all walls are primed with and dried. If the wall is not flat enough, then its is leveled with putty, which can be purchased in pasty state or in a dry mix.

Wall spreading

No matter which filler is used for leveling the walls, its needs to be well prepared and brought to the required consistency. This will help the drill with a nozzle-mixer. The resulting mass must be completely homogeneous, otherwise it will not make the surface smooth.

• The prepared is taken from the bucket with a medium size spatula or trowel and spread on the edge of the wide spatula. With its help, the leveling mass is applied to the wall with smooth movements. The material can be applied to the surface from the ceiling, floor or from the corner, main is that the mixture should be distributed evenly. Immediately all the strips and other flaws remaining from the corners of the instrument are smoothed out.

• After the walls have been filled, the is left to dry. This cc will pass fast enough, as the material layer should be quite small, only 2 ÷ 3mm .

• If the putty has laid well, the next step will be to go its grout using grater .If necessary, on top of the first layer, you can impose a second, finish, and after drying go to the final grout.
• Grouting is performed by the with light in a circular motion counter-clockwise until the surface is perfectly even.
• After completing these works and achieving the desired result, it was not bad that the would have the wall thoroughly vacuumed from the shpatlevochnoy dust, but so that you do not leave the brush with an vacuum cleaner of random scratches.

• The is then applied to all prepared surfaces with a primer, which should be given 5 ÷ 6 hours for complete soaking in the walls and drying out. The primer can be white or transparent. Applying to its is best done with a roller, but it is also possible with a wide brush, especially in hard-to-reach areas( in corners or in pipe passages and , . )

Then you can proceed to the preparation of the paint.

Preparation of paint and selection of the shade

When you open the paint cans you can see that its consistency is usually quite thick. Composition of such a viscosity is good is suitable for creating relief wall patterns, but for painting it still thick. Therefore, , after intensive mixing of the emulsion, its can be slightly diluted with water to the desired state.

• Water is added in very small amounts to prevent excessive dilution to a condition unsuitable for painting vertical surfaces.
• Using different colors and shades of water emulsion, you can create amazing interiors of rooms. However, to realize the intended, will have to "conjure" over white paint, adding to the with the chosen color, and the more it is added, the brighter the paint will turn out.

Color is added gradually, and after each addition the paint is thoroughly mixed.

• In order for the to obtain the same color for all surfaces of the room, you must immediately determine how much color is added to each jar or on the paint bucket strictly of the volume specified. And still it is better - to prepare at once such quantity of a paint of the necessary color which will suffice on all surfaces of a room.

The only digression, which recommended - is to cover the wall, on the of which the is a window, the coloring composition is one or two shades lighter than the of the three other walls. This combination will visually expand the space of the room.

• It was not bad would have the part of the manufactured paint left in reserve so that in the case of the abrasions of the walls in separate places, they could be brought into the proper view. Prepare exactly the same color later - the task is very difficult.
• If several colors of paint are used in the room in a room, then you can not do without a painting tape. It is allocated a separate part of the wall, which is painted in one color. After the final drying of this area, the tape is pasted on the other side of the border, and next is applied the second selected color, and so on. In this way even fairly complex mosaic drawings are performed.

water-based paint. Painting the walls

• Water-emulsion paint is applied in two to three layers, depending on the degree of absorbency of the surface. To reduce this absorbing capacity, the walls need very good to prime , about than already mentioned above.

• Prepared paint in a small amount is poured into a clean tray, from which its is conveniently picked up with both a brush and a roller. In addition, the ribbed surface of this paint tank helps to save material, because about it squeezes excessively taken on the roller or paint brush.
• Roller dipped in the paint and scrolled it in it, so that all of its "coat" soaked in the composition evenly. The first brushstroke is best done on a sheet of cardboard. If it will be seen that the roller is well impregnated, then you can install a long handle in it and begin painting the wall starting from the top. The sub streaks formed in this case, falling on the unpainted bottom of the wall, will be compared and rolled out in the process of work.

Large areas are covered with a roller, and angles or inaccessible places of its penetration, are painted with a brush.

• The wall painting should be carried out in two or three layers, always with after drying each of them - only then a uniform color coating will be obtained.
• During the drying of the coating, it is necessary to protect the room from the occurrence of drafts, as they can damage the evenness of the walls, due to the fact that the areas will dry out in such conditions unevenly.
• On the flat and dry surface of painted walls, often through a stencil or with a special nozzle on the roller, the drawings can be painted in a different color. With such decor you can revive a boring monophonic wall.

• Another option for creating visual texture can be applying to the dried out surface of the paint of a different tone with a sponge, compressed polyethylene or other homemade devices.

- The first layer of the surface coverage is made by the base color. Such a layer should paint the whole plane perfectly smoothly. In this case, you can use the - spray gun to cover the main layer, it will help paint penetrate all the deepest places of the relief.

- Next, the takes paint on the two or three tones lighter than the base color, and preferably a much thicker consistency. It is typed on a clean roller, which without pressure is carried out only on the upper layer of the texture pattern. This should be done very carefully, since you can damage the first base layer and will have to carry out the laborious adjustment.

Having chosen an invoice coloring, it should be taken into account that the paint will need almost twice as much, since the upper textured or overcoated layers will be applied with a thick, undiluted paint composition.

Painting of walls can be called creative, because with the help of water-based compounds it is possible to create works of art - it is only necessary to include imagination and imagine a room in the final version.

If ideas do not arise, then you just need to choose a color that will suit all the tenants of the house, and start working. It is not difficult to paint a finished flat surface, the main thing is to make the walls - smooth, but is - enough laborious process .The creative part of the design of the room will pass easily, as the case will go to completion and to receive of the updated , created by the interior.
