Advantages and disadvantages of latex paint
latex paint has a number of significant advantages.
Firstly, it is quite dries quickly.For dry sometimes only need a couple of hours.
Second, the paint completely bezvrednp and completely safe for the environment and human health.During paint work is not necessary to promptly leaving the room.
Third, in the paint no sharp specific smell, which basically maintained for 2-3 weeks after completion of finishing works.
Fourth, the paint composition can be given almost any color, adding special pigments.In shops for construction, usually sold colorless tone, and invited him to a directory with pimento.The user can select the desired color and on-site technician will give water-based paint the desired hue.
Fifthly, the process of applying the paint is quite simple, and paint tools are easy to clean after use.
Deficiencies in latex paint is significantly less than the merits.The main disadvantage is that you can produce the coloring process only at a temperature of + 5 ° C.
Specifications latex paint
Before you buy a water-based paint, you need to pay attention to its technical characteristics, which include:
- The share;
- storage conditions;
- shelf life.
The ink composition includes: a latex, a filler, a thickener, and preservative.
consumption water-based paints - 1 layer of about 150-200 ml / m2.The absorbency of the base depends on the desired number of layers.
Viscosity - a measure that determines the degree of dilution of the dye mixture with water.Vymeryat viscosity with a viscometer, and should be about 40-45 sec.using ink brushes, 20-25 when applying paint sprayer.
The proportion is about 1.35 kg / l.
Drying time depends on temperature and humidity, it can vary from 2 to 24 hours.Optimum temperature during dyeing premises latex paint - is + 20 ° C and humidity - 65%.
Types of water-based paints
Today, depending on the polymer, which is part of the paint are four main types of water-based paints, namely:
Acrylic water-based paints
This type of paint is currently the most common.As the main component of acrylic resin paints are used, and therefore latex got its name.
Very often in the latex was further added.This connection allows the components acrylic latex paint to actively resist water.This suggests that the colored coating can be easily cleaned with water without fear, because the paint will come into disrepair or even washed away.Manufacturers in the characteristics of the paint very often point out that it is able to transfer up to five thousand washing water.Double layer of acrylic paint with a latex filler can mask cracked surface thickness of 1 mm.Acrylic latex paint, the price of which depends on many factors, very well lie on the surface of wood, glass, concrete, brick, plaster, concrete and metal which has been pre-primed.
striking example of such a coloring agent is a latex paint veak.She has no specific, unpleasant odor, it is safe, quick drying, and work with paint veak very easily.
silicone water-based paints
The silicone paint, similar to acrylic, silicone present in the composition of the resin.
Such paint, despite the relatively high cost, is perfect for all mineral surfaces with no problems able to paint cracks up to 2 mm.Silicone based paints are classified as vapor-permeable coating.This quality allows you to use the paint on wet and prone to the appearance of water surfaces.With a paint can for a long time to forget about the fungus.
water-based paints Silicate Silicate
kraska- latex is a mixture of an aqueous solution of sodium silicate and color pigments.
This type of water-based paints has excellent steam, air permeability and good atmospheric stability.Silicate paint will last at least 20 years.
But it is worth noting that if the environment in which there is a coating, is more humid than the colored material, it is best not to use this type of latex paint.
mineral water-based paints
As part of the mineral water-based paints present hydrated lime or cement.They are used for any surfaces when painting walls and ceilings.However, their main purpose - is painting with concrete or brick surfaces.The disadvantage of these types of water-based paint is considered a small lifetime.
paint latex polyvinyl acetate obtained by mashing pigments polyvinyl acetate emulsion.The advantage of these colors is that they are diluted with water, and they can even work indoors while maintaining good working conditions.Their film sufficiently high strength, resistant to moisture, grease and mineral oils, and they are light resistant.
painting with latex paint
in painting with latex paint room has its own nuances.
Before using the paint should be mixed thoroughly until smooth.If the instructions state that the paint can be thinned with water, it is best to do this, so the paint more evenly lies on the surface.If there was a desire to give the interior as much as possible the bright colors, it is not a problem.To do this, buy a color scheme for water-based paint.This makes it convenient thing to do from the usual white colored paint, while picking up the desired hue by mixing.
Initially, the paint is better to dissolve in any small boat, alone, put on the board and allow to dry.Only then you can determine whether or not the group.It is worth noting that the paint has a slightly different shade than the dried coating.
ink surface must be flat and prepared for painting.Before applying a mixture of a wall or ceiling should be zashpatlevat and primed.
on by choosing colors for the room, there are certain rules.If the room window facing south, the ideal would be cool shades: purple, blue, green, blue.If the windows facing north, it is better to choose warm colors: magenta, yellow, red, pink, orange.When choosing colors should not be a problem, since the color latex paint is very diverse, thanks to every consumer be able to meet all their wishes at the expense of the surface color of its premises.
Paint the walls with latex paint
Before you start, you need to free up as much as possible room to plaster all the irregularities, if necessary, and rinse thoroughly with putty walls.Do not forget about the mask, goggles and gloves.
During painting putty walls is best to apply three coats of paint, the first is the soil.When painting the walls with wallpaper will be sufficient to two layers.
Dye need stages and parallel bars, and the need to move away from the window to the opposite end of the room.
To maximize the quality of staining of surfaces is recommended to use special equipment.One of the most popular devices for facilitating dyeing process is airbrush.
Spray for latex paint - it's a great assistant that will stain any surface without gaps and molasses.They are very productive and have a large surface area simultaneous coverage.
order to paint the walls with latex paint with a brush you need to take a broad brush of 100-125 mm.And immerse it in a third bristle paint.Then you need to press the brush to the wall of the container in order to get rid of excess paint.To begin you need to apply paint from top to bottom with short horizontal and vertical movement.
application of water-based paint with a roller - the fastest way to paint the surface, but in this case more layers than the paint brush as roller forging paint thinner layer.The tray should be about one-third filled with paint, then lower the roller in the ink mixture and roll it across the surface several times.This will help distribute the paint uniformly over the entire roller.Then you can begin to paint.Roller the wall must be carried out in different directions, while uniformly applying pressure to it.We must do everything carefully and slowly, otherwise the paint can squirt.
Paint the ceiling latex paint
most important thing here - it is applied in a uniform layer on the surface of the ceiling for this entire roller should be covered the same layer of paint.In order to achieve a uniform distribution of paint needed umoknut roller in the paint, and then roll it over the surface of the tray or on a specially prepared materials, such as linoleum.This process can be repeated, if necessary several times for the ideal distribution.If you skip this process and go directly to the stained ceiling, then because of the uneven layer after drying on the ceiling may have spots from which you can not get rid of in the future.
Apply the paint with latex paint for the ceiling should be parallel strips that overlap by approximately 2-3 cm.The duration of the application of one layer is about 30 minutes.To be perfectly painted ceiling, you need to apply 2-3 layers of paint and the thinner the layer, the more uniform is the surface after drying.
In painting the ceiling is very important direction of paint coatings.The last layer should be positioned towards the light source.This can hide possible irregularities in the coating structure.After staining the entire ceiling, you can go to the color of the places where it is not pulled out roller, namely the joints and corners.You can use a brush and gently apply a small layer of water-based paint on the unpainted surface.
How to remove latex paint
most unstable to moisture is a latex paint for the walls and ceiling on the basis of PVA (polyvinyl acetate).To remove this type of paint is enough just to be a sponge with soap agent.
order to wash acrylic latex paint that is resistant to water and soap solution, it is necessary to use mechanical means - a spatula or a disc angle grinder.
Another effective way to remove the mechanical spatula considered preliminary pasting cleaned area newspapers.To prepare the glue to cook the starch in the consistency of sour cream, or buy an ordinary wallpaper paste.After drying, the adhesive paper from the paint will be easier to remove.
Also, the paint can be cleaned with a chisel.It is a tedious process, but the paint can be removed very efficiently, without producing excessive noise.
latex paint can still be removed with a hair dryer building, annealing place section by section with the old paint.At the same time, you can gradually help spatula.This method is suitable for the purification of acrylic latex paint.
can also use the stripper on a chemical basis.After its application to the cleaned portion, it will begin to be absorbed into the paint and gradually destroy it.
