Acrylic paint for wood for exterior
In Russia, a traditional material for the construction of houses has always been considered wood. It is to this day remains one of the major building materials, since it derived from an environmentally clean, comfortable, warm, and beautiful residential buildings. However, there is one negative point that is able to spoil the overall appearance of the house - front wall in two - three years, begin to lose their natural color, darkening and dimming, and the tree cracks.
Acrylic paint for wood for exterior
To avoid these unpleasant symptoms, external wood surfaces need to provide additional protection against weathering. For this purpose, coating materials produced on different bases. Very good performance for such applications has acrylic paint for wood for outdoor use, which is one of the most popular tools. Using this paint will not only help preserve the wood from damage, but also gives an aesthetic structure, and an exclusive appearance.
This publication will be a detailed comparison with other acrylic paint compositions. Next, proceed to examine the issues of acrylic paint consumption and basic technological methods of its application on the wooden facade. Well, as an aid in the choice of material - it will be given a brief overview of the most popular brands among finishers acrylic facade paints.
Comparison of different paints for wooden facades
In order to evaluate the advantages and disadvantages of acrylic paint, it makes sense to compare it with other compounds. So, for the decoration and protection of facades of wooden houses are most often used three kinds of colorful compounds made with oil, alkyd and acrylic based.
"Competitors" acrylic paints - "for" and "against"
The main components in the ink composition of the type considered binders and coloring pigment. Binder component often acts as linseed oil, as well as a coloring pigment used mineral finely dispersing powder that does not dissolve in the binder. This component is harder binder, so be sure to produce dense sediment, and before using the paint on the bottom of the package, it should be thoroughly mixed. However, this quality is typical for most formulations.
Oil paint, despite the emergence of new compounds, is still in the top of popularity
To choose the right oil-based paint, you should familiarize yourself with the options to be brought to the attention of:
- Besides the main components of the oil-based paints are film-forming components which must be at least 25% of the total weight of the ink. The higher the score, the more durable the coating will be, but these components significantly reduce the viability of the solution after opening the package. In the closed form of the paint can be stored for a long time.
- In addition to the film forming, it is equally important amounts of volatile substances. Qualitative paint must have at least 10% of the components of the total solution. However, these substances tend to be toxic and harmful to human health, their evaporation occurs at temperatures greater than 20 degrees - you need to consider when planning a painting.
- The next indicator of the quality of the dye composition is the degree of fineness of the coloring pigment. If the grain size of grinding will be less than 90 m, the paint applied to the surface creates a smooth decorative and protective layer, but if this rate is greater, the surface becomes rough expressed.
- Consumption of the ink composition depends on paint viscosity and fluidity, and the time of its solidification. Qualitative material on existing standards, must have a viscosity index in the range of 65 ÷ 140 units. (Seconds). Drying time, declared by the manufacturer, must not be more than 48 hours or two days.
- An important property of oil paint is formed by a hardness of the coating. Especially important in this setting it is when the paint is applied to the exterior trim. The above claimed composition hardness index is, the more durable the coating will be.
- Hydrophobicity for paints, used for exterior trim must be absolute, and the interior finish composition can have a lower index.
Update facade decoration oil paint wooden house
Oil paint is almost always used for the renovation of an old wooden house, painted earlier the same composition. The fact is that the paint on a different basis have lower rates of adhesion to the old layer of oil.
Of the characteristics of oil paint are the following its properties:
- The composition has good adhesion with the prepared (primed varnish) wooden base.
- There sufficiently low resistance to ultraviolet rays - painted surface quickly fade and lose their initial gloss. Therefore, if the exterior finish choose this kind of paint, it is best to focus on light shades - effect of burnout will not be as noticeable.
- Freshly applied paint produces a steady unpleasant smell, and it disappears soon.
- The dyed oil paint surface dries sufficiently long, so that at the applied layer is not adhered dust particles, such finishes must be done at calm weather, and, in view of 1 ÷ 2 days for drying.
- The maximum duration of the operation of the oil coating is not more than 6 ÷ 7 years, and this period may be even significantly less under adverse environmental conditions.
Alkyd compositions are based on alkyd varnish, fillers, solvents and ink pigments. As the solvent used most often white spirit, this same solution is added additionally in the case when the paint thickens.
Bank universal alkyd enamel
The main binder component in these formulations is the alkyd varnish, which may be of two species &# 8212; Phenol and Nitrocellulose. Nitrocellulose lacquer is used most often for the manufacture of paints and community purpose &# 8212; It is a thick resin diluted in a solvent which is added glycerol and rosin oil.
Fillers are added to the solution, often are such materials as milled into flour granite and marble chips, sand or other materials with similar characteristics.
Alkyd paints, coatings produced degree of elasticity significantly superior oil
Alkyd paints have good elasticity and durability of the painted surface quickly dries - this period is 6 ÷ 12 hours, depending on humidity and ambient temperature. Surfaces coated with this paint, during operation does not burn out, the applied layer does not shrink.
Enamels made based alkyd paints are labeled according to their purpose, and, accordingly, differ in their properties.
- Field of application of the alkyd paint is determined by its alphanumeric code. For example, PF-115 can decode coded as follows: PF &# 8212; Nitrocellulose is the basis of the composition, the first digit of "1" means that the paint is designed for outdoor use, and the number "15" - a code of enamel in the catalog. PF-115 solution for wood and metal surfaces - it creates them glossy coating.
The paint marking, except one, are used, and other figures - it is useful to know:
|0||Priming enamel which is used to prepare surfaces for painting.|
|2||Interior paint, suitable for heated and unheated rooms.|
|3||Enamel, intended for temporary oplombirovki equipment. they are often called conservation structures.|
|4||Enamel with strong water resistant and hydrophobic properties.|
|5||Colorful formulations with specific properties - glowing in the dark, and other rodent repellent.|
|7||Enamels with high resistance to aggressive chemical environments.|
|8||Compositions enhanced thermal stability.|
|9||Paints with special qualities -elektroizolyatsionnye or conversely conductive enamel.|
Alkyd paints are different low price that, in principle, and determines their rather successful - that this criterion is often a determinant in the choice of the composition. In addition to the advantages include the following:
- Such colors - good weatherability, high and low temperatures, in the range of -50 to +60 degrees.
- A variety of options - compositions may be opaque, semi-matt or glossy. For outdoor works perfect gloss paint, as they have a longer service life - about 20% longer than other alkyd enamels;
However, inherent in alkyd paints, and numerous shortcomings that must be taken into account when choosing the material for decoration wooden facade.
- Such paints are flammable compositions, that is, the degree of flammability of the building increases.
- In alkyd paints - a very low resistance to an alkaline environment, and with modern precipitation - is not uncommon.
- Over time, the applied coating becomes brittle, loses luster gloss, and it appears cobweb yellowing and cracks.
Alkyd paint freshly painted surfaces may be rich in saturated colors. But in the external application that beauty - not too durable.Dimensional parameters to be coated WALLS

The technology of applying an acrylic paint on a wooden facade
Before you begin the process of staining the facade, walls need to prepare the surface, and it does not matter, the new home will be exposed to the finish, or have "experienced".
Preparation for painting and paint application is carried out step by step, in several stages:
|The first step is carried out audit of the surfaces to be painted. |
If the building is new, the boards must be treated sandpaper until smooth.
Works are made using a grinding machine (eccentric, as shown, tape or vibration) to which is fixed grit sandpaper № 60 ÷ 80 for primary treatment.
For secondary processing, providing surface smoothness, used paper № 120 grit.
|In the event that the house used for the cladding siding with the grooves in the panels joints work more complicated - they sweep by a special corner nozzle.|
|If the acrylic paint will be applied to the facade of the old house, previously trimmed another kind of paint, acrylic, or the same, but have already begun to flake off from the wall, then to achieve the desired result, end of life will have to clean off the coating. |
Large areas of the walls are cleaned using the same grinder, and fine carved details, such as trim, have cleaned by hand with a spatula, sandpaper or with heating layers of old building hairdryer.
|The next step wooden walls should be primed. |
For this purpose, experienced craftsmen are advised to choose a primer on acrylic-based antiseptics. Thanks to this composition can be avoided in the blue timber and fungal structures, increase the adhesion between the materials, to provide a cost-effective application of paints and distribution, significantly reducing the total consumption.
Acrylic primer applied in two layers, with a time interval of about two hours, but not less, as the primary layer should be well absorbed and to dry before being applied second.
|If the primer is processed Planking log or frame, then the ends of the logs or timber it is recommended to use a special formulation designed specifically for such purposes.|
|While primer on facade surfaces will be dry, it is possible to do the selection of paint colors - you can do it yourself or having special equipment to turn to professionals.|
|Here it should be noted that the color white is able to protect the wood from UV rays, but not necessarily to the walls were white. |
The main thing is to be present in the paint chosen for the staining of the facade.
However, the creation of the desired shade is still held at the base of white basis.
|Then, a first layer of paint applied to the surface of the walls. |
It do not too thick, but it should cover the entire finished surface.
Full drying period before application of the second layer always points to the manufacturer of the packaging container.
|Next a coat of paint must be applied after drying the first and completely block the translucent color of wood. |
Staining may be carried out not only with a brush, but a roller or a sprayer.
It is very important good paint over all remote places, and this is done by hand, using a narrow brush.
How to choose acrylic paint for wooden facade
Criteria for selection of paint
In DIY stores you can find a variety of paint products manufacturer as a "heavyweight" in the field of the construction market, as well as little known. And to make the right choice, it is necessary to keep under review the criteria that must comply with acrylic paint.
|Weatherproof||Damage paint layer must reliably protect the wood surface from rain, wind and dust. In addition, it is important to take into account the winter and summer temperatures, as well as their differences. |
On the packaging the composition of those data should be indicated.
Poor quality paint, having survived the first winter, begins to crack and crumble.
It is clear that a prerequisite is the selection of paint designed specifically for outdoor use (can meet some, but also quite understandable term - weatherproof).

In addition, intermittent UV-resistant paint quickly lose brightness, and has assumed a whitish plaque.
Therefore, you should choose foods that have in their composition special components that can reflect the sun's rays or exhibit inertness to their influence.
|durability coating||To apply color coat has served as long as possible, it is necessary that it has a margin of safety, that is to durability parameters were slightly higher than necessary for the specific region.|
|The durability of the coating||The period during which the manufacturer guarantees the coverage of their decorative and protective qualities, usually stated in the passport and on the product packaging. |
Clearly, the better the paint, so its service life is longer.
|The presence of antiseptic additives||Even if the wall had been previously treated with primers antiseptic compositions, it is recommended to choose the paint, which also includes a special additive to prevent biological decomposition of wood, its defeat and microflora or insects.|
