Painted walls with latex paint: how to paint with their hands

Before you equip the room, engaged in finishing. Without a successful background, beautiful design is not, and in addition there is always a need for a practical coverage, ease of care. On the design of the walls are working with great diligence, because it is - a person flat, and aesthetics, they have to be better than the ceiling and floor. The choice of paint, wallpaper or panels - only part of the story. For example, when it is the first option was chosen, it remains to decide what the basis would be better. Newcomers in the repair business is to choose water-based paints, because working with them does not bring a lot of trouble.

Solutions based on an aqueous emulsion with colored pigments are gaining in popularity. Last but not least - because of the light of the chemical composition, safety and low cost. Everyone who started repair should find out what all the same good water-based materials, like paint the walls with latex paint, and what actions need to perform.

paint Features

As the name suggests, this type of ink is an emulsion. Its coloring elements to dry the mixture remain undissolved. After the emulsion has dried, coloring particles acquire a film structure.

The chemical and physical properties of the material make a perfectly smooth wall achievable result. At the same time care for the resulting surface will not be difficult. Enough small damp cloth and effort, and the coating becomes clear, while maintaining appearance. Water-based formulations are suitable for children's rooms, delicate surfaces, variety of colors are also used in the bathrooms.

Due to its characteristics during storage of the raw material is stratified fillers and the aqueous solution was separated. It helps building mixer, which is used immediately before the application of paint. In the bucket it sometimes has to be diluted with water as a wet component can evaporate.

In order to know what will be the intensity of the spray gun, it is necessary to ask the viscosity index.

Advantages and disadvantages

Water-based solutions do not carry any threat to human health or nature. None of the known types of paint is not composed of toxic or other dangerous substances. Raw material does not emit a sharp odor that consumers feel during dyeing other types of solutions.

Once the water evaporates, the master proceed to the next stage of work. Producers promise a very quick drying, but in fact have to wait even a day or more. Still - it is relatively fast.

Compositions based on aqueous emulsions impart any color without exceptions. Is used for this construction mixer and additional amounts of pigments. Pure colors can get even an inexperienced person. With all of this to the purchaser immediately opens worthy palette of ready solutions.

Material is washed with water, solvents are not used. Tools and hands are clean in less than a minute.

Shortcomings in water-based solutions, too. 4 is to provide the key disadvantages:

• poorly suited for glossy and metal surfaces;
• Water paint formulations easier to forge;
• lie down easily, but not as uniformly as a thick paint;
• they are often overspend.

Types and characteristics of water-based paint

Among the varieties of this type of finish is to provide:

• acrylic;
• silicone;
• silicate;
• polyvinyl acetate.

Water-based mixture on the walls quickly become alert. Usually it takes about a day. Paints dry for 20 hours, sometimes less than 10, in some cases - for more than 48 hours. Meet GOST compositions do not emit a pungent smell, easy to movement of the tool, acquire any shades and long preserves the integrity of the surface. The viscosity of the solution is adjusted depending on the application method: apply with a brush material with the rate of 40-45 units and with a spray - 20-25. The paint is applied in one or more layers, and only 1 m² takes an average of 250 grams.

The most "weak" option consider PVA solutions. Although they are cheap and better than the rest suitable for wood and porous surfaces, in this case - can not tolerate moisture and lose to other varieties in terms of durability. Acrylic blend - an expensive and high-quality version of the water-based paints, silicone formulations claim to be "Golden mean", but the silicate with proper selection are the ideal solution for rooms with normal conditions.

Acrylic latex paint

Often they use it up. Is made of acrylic resin solutions and additives as inclusions. For example, a latex additive allows to apply the paint in places exposed to water. Painted surfaces can be washed without fear that the quality of the coating will be worse.

Acrylic water-emulsion mixture is applied to the wall including a drop of up to 1 mm and chaotically arranged roughnesses. With regard to types of surfaces, the acrylic variants differ most versatility and are compatible with the plastic, wood, concrete and even with glass. Among all types of water-based acrylic composition is best suited for metal plating, not least due to the fact that it has anti-corrosion properties. It also dries better than others. Enough of a few hours to proceed to the subsequent manipulation. Due to the high cost of conventional mixtures paint manufacturers have also made with acrylic copolymers.

The silicone latex

Material used in damp areas, as well as in rooms where moisture is formed. These use cases are suitable for these solutions due to the fact that the silicone base gives them high rates of water vapor permeability. On the painted silicone paint surface does not breed mold and fungus. The re-emergence of these microorganisms walls and ceilings, too, will not run. At the same time the parameter resistance to water mixture of acrylic inferior.

Among the positive qualities noted plasticity, strength and ease of use. The cost of silicone mixtures difficult to classify to the benefits, but value for money contributed to the spread in the market. Latex with silicone-based ingredients to hide cracks and depressions with a diameter up to 2 mm. Silicone solutions find something in between the acrylic and silicate.

Silicate emulsion paint

The emulsion is manufactured from waterglass and coloring additives. The raw material has a low cost and long life. Silicate paint withstands temperature extremes. Resistant to natural phenomena mixture can last 2 decades without updating. In trade there are modifications to the interior and exterior, as well as universal solutions - they are classified depending on the severity of properties.

The colored silicate mixture coating absorbs air in which the moisture is in excess. In very dry conditions the surface will give moisture. With all of this raw material can not be compared with silicon, because the latter is used in places where the damp air on the walls and ceiling are happening constantly. A variation on the basis of glass for façades, close to which is a high water table.

How to choose

Sellers can not distinguish between water-based and water-dispersion paints. This is the first difficulty, and solve it simply: the inscription on the packaging should be a "latex".

The surface of the flats are quickly spoiled, especially grease spots, so washable options should be selected. Of course, if this factor will not be limiting. paint package worth checking for compliance with state standards. Mark on the packaging a little, you need to request a certificate. The very process of production of water-based formulations is not a big difficulty, so fake caught more often than is the case with other paints. Sophisticated equipment and specific materials are difficult to obtain, in the manufacture of no use. This is good for the price, but will have to be vigilant in terms of quality assurance. In addition to these criteria, you should pay attention to the specifics of an expenditure and option purpose - for interior or exterior use.

How to choose a color scheme

Kohler range of substances:

• color with metallic or pearlescent;
• universal paste for enamel;
• concentrates with liquid consistency;
• pigment pastes.

Universal kolorirujushchie paste suitable for epoxy, nitrocellulose and polyurethane enamels. The pigment used with wood and lumber.

For vodoemulsionok maximum content kolorirujushchie pastes and colorants is about 20%. At the highest saturation exponent will be maximum, and the processed coating does not suffer from chemical attack.

Tinting pigments themselves are of natural, or inorganic origin. The first group of the color more vivid and deep, but the compositions do not have high light fastness with them. The surface will be exposed to the action of alkalis. The natural Kohler include Umbria, lapis lazuli, ocher, manganese and others. Artificial colors like carotene or rhodopsin produce a mixture of high lightfastness, but the colors leave much less.

should know before they purchase, what will be the end result, and for that use special directories. Excessive concentration will lead to a change in the properties of the paint, but because of too low content of the raw material will often interfere.

Surface preparation for painting

Under suitable staining of wood, plaster surfaces, drywall, tile panels and even wallpaper. First remove unnecessary finishing layer: the old finish is not usually allowed. In the role of universal tool to remove material from the wall using a putty knife. Then move to level. To do this work with flaws and eliminate small differences. In the case of pronounced disadvantages make thick leveling layer. After moving to grinding.

Carry out leveling on beacons. At least, if the plans include the use of solid surfacing materials under paint. The next thing to go eliminate cosmetic defects and Shpatlevanie base and finishing layers. Subsequently the surface is cleaned and primed. It makes no sense to move to staining without filler and primer, because then the stability of latex paint will be called into question.

Cleaning the walls of the old finish

Old walls are usually cleaned from:

• wallpaper;
• paints;
• whitewash;
• plaster.

As for the wallpaper, then they are removed spatula. Enough to pull the strip edge and to have an angle to the tool. Then make a leisurely up and down movement. In which case the wallpaper soaked with water and leave for 20 minutes, so they soaked.

The paint is removed with a spatula, chisel, scrapers, construction dryer, solvents and the perforator. The basic set of tools depends on the type of surface and the paint itself. Of plaster, of cement, concrete and brick walls of the paint is removed in different ways. Oil to remove the most difficult, especially with the concrete. If required, use mechanical, chemical and thermal methods of removal.

Old whitewash eliminate dry and wet methods. In the first case used sander, and in the second - spatula, water, sponge and brush.

Plaster can not be removed, but will have to do it in all the places where it has a void. It is determined by a thud. To eliminate the finish ideally use the machine for removing the plaster.

Shpatlevanie and priming

After cleaning and smoothing the walls are ready for filler and primer. Putty usually made in 2 layers: the start and finish. The first form of a mixture or a finished solution. It is applied using a paintbrush glass cloth mesh. The first layer made of 2-3 mm thick. Apply first a wide spatula and then spread narrow. Then put the grid and increase the base layer, has about 2 mm. Finishing coat is 1.5-2 mm is formed when the dried starter. Use a small fraction putty.

Before priming dust removed from the walls, for example with a soft bristle brush. As a primer is often selected acrylic because it is suitable for almost all types of surfaces. The formulations are applied with a wide brush, spray or roller. After 4-6 hours the coating dries and becomes ready for painting.

Methods for applying the paint

The main varieties have 3: roller, paint sprayer and brush. Last - the most delicate, and apply it to the wall lead to a state of readiness or under the final artwork and decor. Roller is a tool for rapid and uniform dyeing a large area. Sprays are doing everything for the master and very quickly, but control of the device and its stability - difficult moments. You need training and untrained person to achieve the ideal coating is unlikely, at least at the first attempt.

In addition to selecting tools is also determined ideal consistency from watery to very intense. In this sense, it all depends on the type of work. Before you paint, you should apply tentative strokes, because the opportunity will still have to change the shade and avoid large expenditures. The number of layers making 3 or 2 - the first variant of the optimal second acceptable. The remaining solution is hardly suitable.

How to prepare paint

It was diluted with water if the consistency is thick. Manufacturers produce different density options, and what to stay - the question is individual. Textured paintings latex paint only do dense compositions.

A stirred solution of low speed drill with a nozzle-mixer. The composition is stirred immediately before starting work. In particular due to the fact that there is no guarantee that after the addition of the substance kolorirujushchie resulting color will not be disturbed. Part masters adds color immediately before applying to the wall. As for the color, it is necessary to take into account the change in hue after drying and great visual richness of the composition in the container.

To produce a solution for the application may be at the point of sale. In this case, as in others, the material should be prepared to work at one time and all of the walls in the room.

roller

The fastest way of drawing - working roller. Soft paint tool part is made of polyamide velor, pile and foam. Prices are almost the same.

not suitable for water-based foam formulations best way. Pile tools paint all surfaces, and for emulsion paints are suitable as an opportune moment. It should be controlled to remain on the surface of the villi. Smooth wall paint roller with a short or medium nap, and long, in turn, does not fit in one type of work. Velor tools on the one hand too hard to absorb the solution, but at the same time easy to cope with the impact of active chemicals. Polyamide rollers is preferred by professional painters. Primarily because of the durability and compatibility with mixtures.

When choosing a cushion is necessary to pay attention to the uniformity of pillows and placement quality lint / thread.

Spray guns are:

• Hand
• electrical
• Pneumatic

With the hand sprayer, which is operated by movement of the piston, it is difficult to handle alone. For the air supply must meet the other person. In this case, a uniform application of pigment on the wall will ensure smooth movement scrutinized.

An acceptable result is achieved with perpendicular position of the device. Indirect angle relative to the floor at the output will diffuse areas and stains. By sudden movements on the cover will divorce.

Even before the start of the main coloring attempt at the training surface. Without it will not adjust the diffuser, and the instrument in this respect can be called "naughty." When painting the walls can not do without the control of the distance from the floor and ceiling. Otherwise, they will get the composition. In which case do protection for foreign coatings. Space on the wall, missed for various reasons, then treated with a brush.

Creating a textured surface

Texture of paint can do the most, and - forming a combination of finishes and water-emulsion solution.

Use, for example, a combination of plaster and mixtures thereof. Then at the start finish applied on color. Paint roller with bristles of medium hardness, to fill the cavity. Remote places also treated with paint from spray. Then, the projecting members cover different shade - with a sponge roller or bald. Easily be able to create volume, and to the emergence of more complex visual effects need special training.

Give relief and without any textured coatings. In this case, buying a dense structure and does not dilute it. Simple compositions walls are uneven accumulations of paint with thoughtful disadvantages and pimples. With the addition of water forms and drawings make more blurred. Frequently used rollers with uniform surface and a particle materials. For the sake of patterns and color combinations of people agree on the big paint consumption. When applying sophisticated technology it will be even greater.

What is the number of layers necessary

Stain 2 or 3 times. Uniform distribution on putties will be possible after a minimum of 2 staining. Ideally, make 3 layers, and then the color is guaranteed to be enjoyable. The point is not to structural features vodoemulsionku and its layer thickness, and in that the first layer is absorbed in the plaster through the primer mix. Subsequent colorant layer to make the first more complete, and the third second complement. An economical way to provide long-term distribution of the wall solution. Each of the two layers then triturated to yield an ideal form adequate result at a lower cost.

Excess amount of ink in the first reservoir will lead to deterioration of aesthetics and smudge rid of which will be very difficult. When painting subsequent layers placed after partial or complete drying of the previous. During dry room protected from drafts.

conclusion

Water-based paint is considered the least complicated option in terms of choice and worth the effort. Buyers are selected silicone, silicate, polyvinyl acetate and acrylic solutions, the latter sometimes contain latex additive. We can say that the market there is not much variety, but almost every type compounds have resistant varieties. People find a suitable water-based paint specifically for their needs. Coloring emulsions are mainly used inside buildings and outside use those that "are not afraid" of bad weather. Typically, the solutions were applied to the cleaned surface, the Kohler or leave the original color. Before painting walls shpaklyuyut and primed, but in the process - is formed of at least two-layer coating. The craftsmen use rollers and spray guns and brush for the finishing touches. If desired to make the coating difficult, and the texture in this case is selected the thick mixture.
