Wood paint for outdoor use and its types
Wood as a building material has many benefits. It is budgetary, affordable, environmentally friendly and easily lends itself to various types of processing. Although this material has disadvantages, the most significant of them is its vulnerability to atmospheric phenomena. Therefore, dyes are used as finishing not only for decorating wooden elements, but also for their protection.
Acrylic exterior paint creates a durable, dense coating that protects wood from negative external factors
If the dye is selected correctly, the service life of the building material increases.
and provides protection against the effects of moisture, biological pests and ultraviolet rays, which have a detrimental effect on wood.
The modern market allows consumers to buy wood fence paints of the following types:
- latex compounds;
- acrylic-based mixtures;
- dyes with added oils;
- alkyd compounds;
- water-based facade paints.
Almost all paint and varnish compositions have similar parameters, which are due to the common function of these materials - to protect the wooden surface. The differences lie only in the composition and some properties, as well as the decorative effect.
To protect wood, not only dyes are used, but also oils, primers and impregnations
Helpful advice! Before purchasing a dye, it is recommended that you first familiarize yourself with the information offered by the manufacturer, which reveals the properties of the product, its technical and operational characteristics, capabilities, features and composition.
Properties of latex paints for exterior woodwork
Latex or silicone dyes are not in high demand due to their high cost. The properties of this coating are useful for finishing objects used in humid climates. The main component of such formulations are silicone resins.
Latex-based wood stains have the following features:
- high strength characteristics of the coating, providing protection even with a single layer of application;
- resistance to the aggressive influence of reagents (to clean the surface opened with latex dye, you can use not only water, but also alkaline solutions, without fear that the coating will become stained, damaged or lose color brightness);
- inertness in relation to ultraviolet radiation (thanks to this parameter, the coating does not fade for a long time and does not need to be updated frequently).
Latex paints for wood have a high degree of strength, which allows you to protect the coating even with one-layer painting
Latex dyes are characterized by increased resistance to moisture. The material reacts well to mechanical stress in the form of friction and retains its integrity for a long time. Unlike their counterparts, in the form of acrylic paints for wood for outdoor use, silicone-based compounds are less vulnerable to high temperatures and offer a higher vapor permeability. Silicone compounds can be applied over other paints and varnishes.
Properties of oil dyes for facade finishing
Oil dyes are characterized by low cost. Most often, the main component of the composition is drying oil, which is an environmentally friendly substance.
To make drying oil, pressed oil from the following plants is used:
- sunflowers;
- hemp;
- flax.
One of the advantages of oil colors for the facade is a high degree of hydrophobicity, which allows you to permanently protect the wood finish
Apart from being environmentally friendly, this paint does not have many advantages, so it is not as popular as other types of coatings.
Disadvantages of oil based dyes:
- a pungent unpleasant odor that persists throughout the drying time;
- the coating quickly fades in direct sunlight;
- dries for a relatively long time (minimum - 12 hours);
- short service life - 3 years;
- low vapor permeability.
Important! It is strictly forbidden to apply oil formulations over water-based paint for outdoor work. This will require preliminary removal of the old paint layer.
Properties of acrylic facade paints for outdoor use
Acrylic paints are the most widespread and popular group of compounds used for finishing the facades of buildings and other objects.
Exterior acrylic paints are widely used to decorate wooden façade parts
Properties of acrylic-based dyes:
- the composition forms a protective film on the treated surface;
- the finishing has a high degree of protection against seasonal influences and atmospheric factors;
- high wear resistance;
- the surface has good vapor permeability;
- the coating dries quickly;
- the composition does not have an unpleasant odor;
- the finish is characterized by high adhesion;
- the compositions can be independently tinted in any shades.
- long service life - up to 20 years.
Consumers can buy two types of acrylic paint for wood:
- Water-dispersed.
- Solvent based.
Solvent-based acrylic facade paints have other additives. These mixtures contain weather-resistant substances, UV filters and an organic resin. All of these components ensure long-term absence of cracks, burnout and moisture damage. Moreover, the coating has a breathable surface. In addition, the material is protected from the negative effects of temperature extremes.
Water-dispersed acrylic facade stains are easy to apply in a thin layer using a spray gun
Several brands offer solvent-based acrylics with special properties.For example, Akrial-Lux can be applied to wood even at low temperatures. Coloring is allowed when outdoors up to -20 ° C.
Water-dispersed dyes consist of fillers and polymers. In some cases, there are compositions with the addition in the form of marble chips.
Properties of outdoor alkyd wood paints
Alkyd dyes are based on resins. As an addition, oils are also present in the composition. The advantage of these materials is fast drying. Thanks to this, dust and debris will not have time to adhere to freshly painted wood, and sudden rainfall will not spoil the result.
Alkyd compositions are inherent in moisture repellent properties. Treated wood receives full protection from liquids, so these dyes are recommended for finishing buildings in regions with high humidity. The same applies to buildings located near open bodies of water. The consumption of facade paint per 1 m2 is 100-120 g.
Thanks to resins and oils in the composition of alkyd dyes, the coating has a high degree of vapor permeability, which is important for buildings located near water bodies or in places with high humidity
This type of composition is not able to penetrate the structure of the material, the presence of paint is only superficial. Therefore, it cannot be said that the tree is fully protected from any impact. During the dyeing process, a strong membrane-like film is formed on the surface. But she absolutely does not let the air through. Moreover, manufacturers omit this point.
Important! Alkyd based paint should not be applied to damp wood. The material should be thoroughly dried before processing. Otherwise, the surface of the coating will be covered with bubbles, after which it will begin to flake and peel off ahead of time.
Alkyd paints are in many ways inferior to acrylic compositions. The glossy shine on the coating does not last long. Gradually, a matte effect appears on the surface. Under the influence of ultraviolet light, a rather rapid shade fading occurs. The service life is also short.
Alkyd-painted wooden surfaces need to be renewed every few years
Advantages and disadvantages of water-based wood paints for outdoor use
Water-based dyes are commercially available as acrylic, silicate, silicone-type compositions, as well as mineral emulsion mixtures. Therefore, the price of facade water-based paint for outdoor use varies in a wide range - from 400 to 5000 rubles.
Advantages of water-based finishing materials:
- high throughput;
- absence of toxic substances in the composition;
- large palette of shades;
- the most primitive tools are suitable for staining;
- painted surfaces are not afraid of chemicals used for cleaning, so you can easily cope with removing stains;
- if the dye gets on the skin or other objects, it can be removed with water and soap;
- the coating is elastic and not prone to cracks;
- long service life.
Items painted with water-based paint for wood for outdoor use, can be cleaned with detergents
There are not many disadvantages. First, the coating is more vulnerable to moisture than other formulations. Secondly, dyes contain water, so the wood can swell after processing. To avoid this, it is recommended to additionally use protective equipment. Therefore, the question of whether it is possible to paint a tree with water-based paint without preliminary treatment disappears.
