What paint to paint the ceiling plasterboard

When carrying out repairs in the apartment hosts a significant number of gives preference drywall constructions.This technology provides a perfectly smooth plane, to create a multi-level original compositions, place the open and hidden lighting fixtures point to give the ceiling is really a unique designer look.

However, all this will be achieved only on the condition that made very careful preparation and painting. on the ceiling plane always become noticeable even minor shortcomings and errors, including traces of low-quality paint.The materials must be presented to the highest standards, and the question of what paint paint plasterboard ceiling, becoming one of the most important .

A variety of such materials in the shops - is very great, but do not immediately buy the first got paint, focusing only on its price from a desire to save money.It is necessary to pass a small "educational program" on the main characteristics and the choice of parameters.

Basic decorative and performance paints

inexperienced buyer, going to the store for paint, often holding a preference its color in mind, forgetting or not knowing that this material is characteristic a number other equally important qualities.

• In the first place it is still possible to put the decorative quality, as, in principle, it is the main function of the paint in a flat - giving ceiling aesthetics.

clear that classic, the most familiar to the ceiling is white, although there could be a variety of options.Variety of colors produced by manufacturers, is large enough, but most Mastero to behold in prefer to use a base color, producing the desired tinting as necessary by using special additives, dyes.

• Depending on its component composition of the paint may have varying degrees of gloss coated surface of it.So, there is a division on vysokglyantsevye highly brilliant colors, high gloss, semi-matt and matte .

- Glossy paint may seem more advantageous in terms of care for the surface - much easier to remove it precipitated dust or random spots.It is more resistant to abrasion to use detergent that is easier amenable to wet cleaning.However, when all this glossy finish is required to show all the flaws and plastering, and painting works - game reflected light makes visible even seemingly quite minor flaws.

- Matte paint like no other right for the ceiling surface.This coating is visually expand the room is good and hide the defects, and even small level differences.But with the operational side of the her indicators worse - soiled place clean will be much more difficult. Nevertheless , in most cases for ceiling work still choose matte is a kind of paint.

- Semi-matt occupies a middle position, uniformly combining the advantages and disadvantages of both the paint.

• Paint can be normal, "flat", or have a textured turn, giving special decorative painted surfaces moth-eye properties.Typically, textured paint for ceilings applied fairly rare, it is more suitable for the walls.

• Regardless of the degree of gloss , can be washable paint that is resistant to repeated wet cleaning of , or does not meet these requirements.Of course, washable materials are much more expensive, and profitable use in those areas where the ceiling area is small, but the concentration of the maximum possible vapor, such as a kitchen or bathroom.Conventional paints are not so expensive, and sometimes more economical to use them, from time to time spending "refreshing" repair.

• important parameter is coverage paint - its ability to make the surface of the selected tone even on the basis of a contrast.Spreading determined by the number of layers applied , which will be enough to completely smooth background.

quality paint is enough two-layer coating, although in advertisements and references can be found on a single layer (masters belong to this with skepticism).If there is no experience with the unknown paint is better to buy a small amount to start and run an experiment on a small fragment of the surface of the ceiling or just remaining a piece of drywall - so it will be possible to determine the its required amount.

• In carrying out painting works important factor is the consistency of the paint, its viscosity and adhesion to a finished surface.Too liquid paint is extremely complicate the work on the ceiling, lead to a large number of losses will not let the uniformity of application.On the other hand, a too viscous material is difficult to work and paint quality will also be low.However, thick paint is easy to bring to the desired condition of the solvent (often - with plain water), but if purchased too thin, the situation is worse.
• There is also the concept of thixotropy - this feature is usually indicated on the paint can with this property.It is the change in density (dilution) with rapid mechanical stirring set at rest viscosity.These paints provide very little sag when applied, but the cost is quite high.

• essential criterion in choosing the material becomes its drying speed.This will determine the performance of painting works - the less time, the faster you can apply the next layer, or move on to the subsequent stages of the overall decoration of the ceiling.Typically, passport documentation paint indicates the average time it drying under normal conditions of temperature and humidity in the room.
• becomes extremely important to the ability of paint to "breathe" for drywall ceiling rooms apartments, ie to free paroobmen .Otherwise, on the surface of the ceiling will accumulate condensation that will and untidiness of his views, and to serious inconveniences.
• And finally, himself a coloring component, and a solvent, and optional ingredients of the material must be absolutely safe for human and animal health and pose no environmental threat.At the same time the paint should prevent the outbreak and spread of colonies of microorganisms (bacteria, mold, fungi).Painted ceiling should have pronounced fire qualities.

What kind of paint is best used for plasterboard ceiling

now worth considering the existing paint from the standpoint of their chemical composition and component.Available in many variations, and you need to know, what on arrival in store generally not taken into account, and what quite applicable for use in plasterboard ceilings.

Paints oil

This type is perhaps the oldest of all the others.Solvent such paints are mineral or vegetable oil (linseed oil), which is in the process of oxidation from exposure oxygen air dries, leaving film coating.

merits of these materials slightly - is low cost and good covering power.JAFI they are very long, the water vapor permeability is very weak, under the action of ultraviolet radiation is a rapid destruction caused layer, and after a couple of years usually it starts to peel off, losing an attractive appearance.

However , «update» surface after oil paint is not easy - want complete cleaning of the surface, since no other top oil already notlie.Conclusion categorical - this paint should not be used for plasterboard ceilings.

Alkyd paints

largely on its operating characteristics are similar to those of oil.The main difference - in the applicable type of solvent.This is usually volatile organic compounds - turpentine, mineral spirits, gasoline and etc .in composition also includes alkyd resins, pigments and special additives that increase the plasticity of the material and accelerate the process of drying.

painted surface receives resistant film , which can successfully withstand many external influences - temperature changes, moisture, UV light.However, with time comes the inevitable fading and yellowing. Paint in certain extent is a vapor-permeable , but still this figure its is far from ideal in terms of premises.Furthermore, the paint is not safe from the viewpoint of flammability.

Alkyd paints can be glossy (enamel) and opaque, they respond well to wet cleaning, resistant to abrasion, after the complete solidification are harmless to the environment and humans.However, to use them on plasterboard ceiling can be exclusively for reasons of low cost and good pokryvistosti .Rather, they are well suited for coating wooden or metal parts and structures as inside and outside the house, but the ceiling is better to buy a more viable option.

Silicate paint

belongs to the category of mineral pigments that are based on silicate - "liquid glass", sodium or potassium.This creates paint on the surface extremely durable layer which at the same time has the highest vapor permeability as compared with all other coatings .

The composition of silicate paints include alkaline components that causes e insecurity during painting works - necessarily means used protect the skin and mucous membranes.After solidification of the composition becomes harmless.

Chemical composition determines the use of color to give extremely alkaline pigments, which significantly limits the range of color options.However, because the white color of the gypsum ceiling is often the best, then this disadvantage is insignificant.

Silicate paints are especially good for rooms with high humidity, and iz for expressed vapor permeability, in connectionantiseptic - on such a surface will never have any colonies of microflora, even without the use of any special soil was.

disadvantages of such paints is also considerable. First , poor flexibility - it can not close the small surface defects - even very subtle cracks will be allocated.The paint had good rests on the ceiling, which was previously decorated with synthetic formulations on an organic basis.You can not be her use when on the surface to have any plastic parts - it simply they are not crystallized.And yet one important caveat - if the ceiling was painted at least once a silicate paint , attempts repaint it a different material are unsuccessful.

water-soluble or emulsion paints

Of all of paints for interior painting works it is water-soluble paints are the most viable option.As of the name itself, a solvent for them is ordinary water in which the emulsion or dispersed state are all the other components:

• film-forming basis - binders different type , which after evaporation of the water creates on the surface firmlyadjacent layer with high adhesion, retaining all the remaining ingredients.
• Pigments - special dyes that give the material the desired shade.
• Fillers - significantly improve the physical quality of the paint and protective layer . In various kinds of dyes can be used talc, quartz or marble dust, other mineral or organic ingredients.
• Special additives - used to optimize adhesion processes, uniform spreading paints on surface water evaporation and polymerization adhesives.

Water-soluble paints are divided into several varieties:

1. On the basis of polyvinyl acetate (PVA).In common parlance they are most often referred to simply as « vodoemulsionkoy» .They are among the most inexpensive of the water-soluble, which leads to their very wide popularity.

The paint has almost no smell, adheres well, it is easily washed off with hands and tools.As a rule, presented in sales only in white, but very easy to give in pigmentation to the desired shade.

latex paint is absolutely harmless, non-toxic and does not emit any fumes, even when exposed to thermal, so it's perfect for covering its plasterboard ceilings in living areas.On it easy to go to almost all the other paint, repaint the surface that is eventually not imagine reflux ore.

main drawback vodoemulsionku - poor resistance to abrasion and to water even after fully cured.Wet cleaning a ceiling it is better not to subject - to it can form visible eye divorce.For this reason, it better used for ceilings only in rooms with normal humidity.

2. butadiene-styrene paint something similar to PVA, but compare favorably with their resistance to abrasion and good resistance to water stress - it is possible to more care for the ceiling surface.However, all these benefits are outweighed by the main disadvantage - such paint is extremely vulnerable to the effects of light - under the action of ultraviolet rays, it quickly loses its original color.
