From this article it is possible to learn that is represented by aqueous emulsion ink for walls and what potential she has. In the text information on all kinds of water-based finishing materials, their technical characteristics and features of application is stated.
Aqueous emulsion ink for walls: main information on group of structures
Aqueous emulsion inks it is extensive material class, the different surfaces intended for finishing. To study these mixes in narrower understanding, it is necessary to pay attention to their components, assignment and method of production. As a part of water emulsion dyes it is possible to notice difficult names of chemicals, however in simple language most of them sounds as silicone, glue, swept, etc. Each type of dye from this category has own advantages and shortcomings which depend on components.
Water in which there are tiny particles of polymeric substances forms basis for these dyes. The paint type depends on the nature of these substances. In addition, the structure contains additional components. Producers use these elements to allocate finishing material with useful properties and to improve its characteristics.
As a part of water emulsion dyes there can be such components:
- fungicide substances;
- antifreeze substances.
Proportions of components as a part of aqueous emulsion inks for internal works
Emulsifier or filming agent is the main making component of water-based dyes. The range of application of finishing material depends on type of emulsifier.
As emulsifiers it is used:
- polyvinyl acetate;
Dye marking directly depends on type of filming agent. In addition structures are filled with mica, chalk, talc, barite. Each of these components can be present at structure independently or together with others at different proportional ratio. As thickener carboxymethylcellulose is applied.
Helpful advice! Specialists recommend to buy during the work with aqueous emulsion ink paint spray gun for high-quality and uniform coating application.
Percentage of components of aqueous emulsion ink:
|Component||Percentage in dye, %|
|Polymer in water solution (dispersion)||50-60|
|Coloring pigments and fillers||35-40|
|Thickeners and plasticizers||5-8|
White aqueous emulsion ink is received by addition in structure of white pigment, for example, of oxide of zinc or dioxide of titanium. All existing types of water-based dyes are marked depending on emulsifier type.
Allocate the following kinds of materials:
Many buyers are interested, than acrylic paints differ from water emulsion structures. Water-based normal mix is not suitable for finishing of metal surfaces at all. For these purposes it is better to take acrylic material which has thermal stability and water resistance.
Main markings of aqueous emulsion inks
It is possible to find the extensive choice of paints and varnishes from different firms in shops. Therefore before buying aqueous emulsion ink, it is necessary to study technical characteristics and markings carefully. These marks allow to make idea of what components are included by mix, what its properties and range of application.
Digit “1” marks front aqueous emulsion inks, the price for which is much higher, than on normal structures. These mixes show resistance to all atmospheric phenomena: to rainfall, low temperatures, climatic changes, influence of ultraviolet and microorganisms.
Digit “2” indicates the structure intended for internal application. Thus, interior aqueous emulsion inks for ceiling and walls are marked.
When choosing dye also normative documents matter. The dye made in full accordance with its requirements is considered qualitative.
Important! Standards according to the specification are significantly reduced. Therefore the dye made according to its norms cannot be considered qualitative.
Use of aqueous emulsion ink: expense, tinting, tool
In shops two options of coloring pigments meet: natural and artificial. When using natural pigment the result will turn out more saturated, however there is probability that the shade of covering will quickly burn out under the influence of ultraviolet. For this reason use of natural color will be reasonable in rooms where direct sunshine do not get. Artificial pigments are not so bright, but show high resistance to ultraviolet.
It is very difficult to achieve necessary shade in house conditions therefore it is better to ask for the help specialists. Having chosen the pleasant shade on palette which is in each shop, it is possible to execute tinting by means of the special machine.
Recommendations about use of color for aqueous emulsion ink
If desired the tinting of structure can be executed and independently. Most often resort to this procedure for the purpose of economy. The cost of white paint and set of pigments is much lower, than the price of the tinted structure. Experimenting in house conditions, it is possible to achieve the necessary depth of color. Besides on photo the color of color for aqueous emulsion ink will not always correspond to what will turn out as a result of mixing in the machine.
Not to be overzealous, it is necessary to enter coloring pigments into structure gradually until color does not become homogeneous. At the same time mix it is necessary to stir slowly all the time.
Helpful advice! To repeatedly achieve the same shade extremely difficult therefore it is recommended to count the expected volume of consumption of aqueous emulsion ink with small stock in advance and to prepare necessary portion for once.
It is possible to carry out trial tinting on small volume to study properties of color. After that testing on the imperceptible site of wall is carried out. It is necessary to wait until the structure completely dries that the color was shown. For this purpose 1-2 days are required.
For rooms of the small size it is recommended to select shades of light color gamma. They can visually expand space. If walls in the room are dark, and ceiling – light, the room, on the contrary, will seem to narrower. Resort to this method when it is necessary to raise height of ceilings visually. It is better if is present at design not Bol of three flowers. It will allow to avoid diversity. Exception is white and black and also shades of the same color.
Calculation of necessary volume of aqueous emulsion ink, expense on 1 m ²
Dye consumption rate usually is specified the producer on packaging. These data help to define approximately how many the structure will be required for finishing of certain area.
General consumption rates of water emulsion dyes:
|Type of water emulsion dye||Expense at primary drawing, g/m ²||Expense on the second layer, g/m ²|
Additional factors can also affect aqueous emulsion ink consumption on 1 m ². For example, structure of the processed surface. Coloring of smooth plaster will require 10-20% less dye, than for processing of textured material. At calculation indicators for the first and second layer are summed up. Besides, it is necessary to consider way of causing structure and feature of the tool which will be used.
Weather conditions can also affect expense and quality of result. During heat water from structure quickly evaporates therefore the covering can turn out uneven. In that case it will be required to level surface, and sometimes to tint spots. Wall-paper under painting will demand increase in norm approximately for 20%. Paper has honeycomb therefore it will absorb part of structure in itself. About 5% of paint are lost when processing ceiling, flowing down on floor.
As it is correct to paint walls with the roller: recommendations
It is not recommended to apply brush to coloring of surfaces aqueous emulsion ink. Use of this tool will lead to increase in expense. Most often for similar works the roller with tray undertakes. In this case the dye consumption, as well as decorative characteristics of covering, will depend on material and fur coat of the tool. It is better to use the roller with long pile for finishing of stucco molding and rough surfaces. For coloring of the smooth basis it is necessary to take the tool with short fibers.
Helpful advice! Application of paint spray gun for aqueous emulsion ink will allow to reduce structure expense significantly. This tool is considered the most economic and suitable for this type of works.
Recommendations about coloring of walls by means of the roller:
- the size of tray needs to be selected so that the tool in it freely was located;
- the roller has to plunge no more than on quarter into paint;
- during coloring it is necessary to press the roller with identical force, passing on all surface to exclude strips and stains;
- for dilution of dense paint it is possible to add water, but it is no more than 10%;
- it is not necessary to dip often the roller, the covering has to turn out thin and smooth;
- it is not necessary to try to apply dye with thick layer to reduce work, it will lead to overexpenditure and emergence of cracks on covering;
- between layers it is necessary to take break (at least 2 h) that dye has dried up.
Whether it is possible to glue wall-paper on aqueous emulsion ink
Aqueous emulsion ink – universal type of material which is combined with different types of surfaces. Quite often there is need for change of design of earlier painted room, for example, to pasting wall-paper. Such option of replacement of finishing is possible, but on condition of preliminary preparation of the basis. For this purpose the wall surface is processed by the solution consisting of glue and soil. Components mix up in proportion 1:1.
Wall-paper can be pasted over water emulsion dye provided that the previous covering is executed by qualitative structure and without violation of technology.
Pay attention! Before starting gluing of wall-paper, it is necessary to check adhesive properties of dye (reliability of fixing of covering). For this purpose the normal newspaper is pasted on wall and after drying comes off wall. If it is heavy to disconnect it, so the covering keeps rather strongly to sustain the weight of wall-paper.
Whether it is possible to paint with aqueous emulsion ink on enamel
Sometimes at wall there is old covering, as a rule, in the form of oil paint. These structures were very popular earlier therefore they were almost everywhere used in houses as finishing. As these materials are incompatible, it will be required to remove old covering.
How to remove old paint from walls:
- Removal mechanically.
- Chemical dissolution.
- Elimination of covering by means of temperature influence.
With enamel it is much simpler. In order that aqueous emulsion ink has laid down over enamel, it is necessary to execute matting or to apply primer. The effect of matting is reached due to putting drying oil though this way has also shortcoming – unpleasant pungent smell.
As an alternative it is possible to apply machining of surface by means of fine-grained abrasive paper. Thanks to it adhesion degree will increase. Similar function is performed by primer.
Whether painting of ceiling aqueous emulsion ink on old paint is possible
To determine possibility of coloring by aqueous emulsion ink over old covering, it is necessary to estimate its condition and to prepare surface. Dye will not be able to hide all defects, especially, if defects are present at outdated paint and varnish layer. All roughnesses and damages, on the contrary, will become visible and bright. As a result all work as the money spent for paint purchase will be gone in vain.
If the plain surface has also no serious defects, before coloring it is recommended to cause the grounding structure. If the old covering exfoliates, the basis should be smoothed out well in problem places. Putting water emulsion dye over old limy whitewash is not allowed. In this case it is necessary to remove covering and to wash out the basis by means of alkaline solution of water.
Water emulsion structures – the most convenient in use and practical types of dyes. Thanks to the extensive range buyers have no problems with the choice of finishing material for internal or outside works.
