Ranking of the best outdoor varnishes for 2022

Lacquer for exterior processing of various bases (from brick and concrete to wood, chipboard and plastic) is used not only as a decorative coating. Proper varnishing is designed to qualitatively protect the surface from mechanical stress and adverse weather conditions. Especially this type of varnishing work is in demand for structures erected in a temperate climate zone.

Outdoor varnishes for hard substrates

These products are particularly resistant to temperature extremes (within small limits), they can successfully withstand moisture. They endow the treated surface with a fair degree of wear resistance, which means an extension of its operational period. Their basic properties include:

• The ability to withstand various aggressive environments (acids, alkalis, hard organics, harsh synthetics);
• Possession of increased adhesive properties, which is achieved due to deep penetration into the structure of the treated surface;
• Improving overall wear resistance and impact strength for natural minerals and artificial stone;
• Weak exposure to high / low temperatures;
• Durability.

Popular types of exterior varnish for brick, concrete, stone

In the first place in this list, you can put polymeric materials that have excellent moisture resistance, excellent strength and increase the period of natural wear. They adhere well and dry fairly quickly. In second place, it is possible to determine polyurethane compounds. They are not much different from the previous ones, but they are superior in that they completely do not let moisture through (if applied with a quality layer). Therefore, their main scope is the finishing of bowls in outdoor pools, as well as the processing of paving slabs. The third most popular will be silicone and acrylic compounds. They do not get too much distribution due to their high cost, but their performance is the best. At the same time, the quality of their execution of interior and decorative works, the results of which will be permanently outdoors in the future, corresponds to the highest level. Moreover, they will be an ideal solution for processing large areas made on the basis of minerals.

Any exterior lacquer used for outdoor applications will include special inclusions designed to provide a certain visual effect. He can be:

• Glossy - creates a completely shiny surface;
• Semi-gloss - gives the base the effect of "wet stone";
• Matte - a somewhat dark shade, designed to hide the flaws of the main surface;
• Semi-matte - something in between the level of visual "velvety" between matte and glossy, but does not have such a pronounced shine.

Polymer

These compounds are most often used to coat standard mineral surfaces and artificial stones.Polymers are able to give good decorative features, while increasing wear resistance. The substance can adequately cope with low temperatures, protect against moisture penetration. Over time, polymer street varnishes do not fade, fully maintaining performance. Regarding the features of their compositions, it is worth mentioning that they are always one-component, which reduces the time spent on the drying process. Fast drying occurs due to the small proportion of the water component. For the same reason, it is allowed to process gypsum objects with polymeric substances, because the material will not soften the base. Most of these varnishes have a matte finish, however, they can be tinted with special additives.

Polyurethane

This varnish can be used for any structures during construction work. The mixture is a polymer including polyurethane. To enhance the consistency, the addition of an organic solvent is allowed. Due to the latter, the solution forms a transparent and durable film during hardening. As with the previous sample, tinting is allowed for polyurethane mixtures. This is very convenient in cases where it is required to create the same type (with a bearing surface) coating. Polyurethane lacquer products are the products that best achieve the “wet stone” effect. Also, the increased protective properties of this substance can easily fit both brick and concrete. If the surface to be treated is made from these two materials, then such a tandem will double the durability and wear resistance. The moisture resistance of the material in question is also maintained at the required level.In general, metal structures sewn into lacquered concrete will be maximally protected by waterproofing properties from any manifestations of corrosion.

Acrylic silicone

This type of product has a dual purpose - both applied and decorative and finishing. The substance fits perfectly on brick, concrete, gypsum, stone and some artificial minerals. Due to special chemical inclusions, the surface treated with acrylic silicone will not turn yellow over time, even when permanently exposed to direct sunlight. At the same time, a resistant moisture-proof film will be kept on the base. The base for this mixture is acrylic acid, including acetylene. Due to this inclusion, the varnish does not have a strong smell, is environmentally friendly and can be used for exterior decoration of specialized medical buildings and small architectural forms (for example, outdoor gazebos in a sanatorium). Application is possible on any solid materials, up to gypsum and metal. Coloring is allowed.

Outdoor varnishes for substrates with limited hardness

Most of these exterior varnishes have a very specific characteristic that accurately describes their basic functionality - "weather-resistant products with protective and decorative properties." In most cases, they are used for decorative purposes, and protective properties are attached to processed bases, as if as an essential addition. However, this does not greatly reduce the effectiveness of protection. The main difference is that it is desirable to use them together with various working additives (from fire-fighting impregnation to antibacterial inclusions), and it is preferable to apply them in several layers.

Basic qualities

Most objects that are made of materials that are not particularly hard (chipboard), relatively fragile (plastic) or have a porous structure (natural wood) require protective treatment if they are used outdoors all the time. Accordingly, the varnish applied to them must successfully fight and withstand the following factors:

• Humidity (typical for wood products) - when water is absorbed and dried, the object will swell, changing its dimensions orthogonally and linearly. The film-forming substance will help to reliably protect it from swelling, lowering the absorption properties to zero.
• Pathogenic microorganisms (typical for wood products) - due to their vital activity, the object of processing will quickly age and lose strength. For most microorganisms, a tree is a nutrient medium, therefore, it is necessary to fight them with the help of antiseptics that are part of the varnish solution and protecting the surface with a strong varnish film.
• Insects (typical for wood products) - control methods are similar to those described above, and the difference is only in the size of the "enemy", and insecticide additives are used to combat it. The film preservation of the surface will lead to an increase in the hardness of the tree and will not succumb to gnaw by pest bugs.
• Flame (typical for wood and plastic products) - processed materials are usually classified as combustibility group G4. The inclusion of special impregnations in the composition of the varnish will help to increase the ability to resist fire. These include various flame retardants, which will expand the scope of wood / plastic in exterior decoration.
• Ultraviolet rays (typical for wood and plastic products) - under their influence, the object will acquire an unpleasant gray color in just a few years. The transparent film of the composition, which has a special light filter in its structure, will successfully retain the sun's rays, preventing them from having a negative effect on the surface of the treated object.
• Temperature fluctuations (typical for wood and plastic products) - this protective property of the applied solution will depend on the chemical component of the base - it should help restore the shape of the film after heating and maintain its plasticity during frost.
• Dirt (typical for wood and plastic products) - due to their extreme soiling and weak antistatic properties, materials with limited hardness, constantly located on the street, easily “attract” dirt. If, however, they are covered with a special solution, then through the formed film for wood, the access of dirt to its porous structure will be blocked, and the plastic will acquire antistatic protection. In addition, it is much easier to remove dirt from the applied film than from the untreated surface.

IMPORTANT! It is worth mentioning that not all varnishes under consideration require the mandatory presence of the above properties in the complete set. For wood, for example, only those products that have antiseptic additives to fight bacteria can be used, but for plastic-based siding, a solution with a light filter to counteract fading under UV rays is better suited. In any case, all these qualities are usually indicated on the container of the material using the appropriate marking.

Popular types of exterior varnish for medium-hard substrates

Oil-resin (oil)

Their main feature is the increased concentration of organic resins, organic compounds and various oils. Due to this structural organization, these mixtures have a thick consistency, and it is recommended to apply them exclusively with a brush. After application, they form a thick yellowish film. In principle, the technology is outdated, but still guarantees proper strength and UV resistance, coupled with sufficient elasticity.

Most of these materials are classified based on the percentage of oils in them:

• From 35 to 55% - "dry";
• From 55 to 65% - medium "dryness";
• From 65 to 85% - "fat".

Of the main disadvantages, long drying can be distinguished, which takes from 24 to 72 hours. Recently, they are rarely used for outdoor work, and then only on wooden bases. The reason for this is the emergence of more reliable compounds. However, if the issue of monetary savings is at the forefront in the production of street finishing works, then these products will be the best solution.

Alkyd-carbide (alkyd)

These solutions are based on pentaphthalic or glyphthalic resins. The role of the solvent is played by white spirit or solvent. A desiccant may be added for faster drying. These dyes are a good solution for coating street structures made of synthetic materials. They are characterized by sufficient strength, well resist water and temperature extremes. If there is a flame retardant in the structure, then the structure will melt / burn through without open fire and the release of caustic harmful substances. Unlike oil samples, alkyd ones have greater transparency. The main disadvantage is the presence of an unpleasant odor during processing, which will disappear with time.The maximum service life of the coating is 2-3 years, after which it will require renewal.

Alkyd-urethane (polyurethane)

In this variety, the base is made on a polyurethane basis, it also contains a solvent and a hardener. This type is characterized by wear resistance, moisture resistance, good resistance to mechanical stress, dries quickly (approximately within 8 hours). The formed film may have a semi-gloss tint or be completely transparent. Easily suitable for facade decoration. Relatively recently, similar samples on a polyurethane base also began to contain a water component. So the issue of increasing environmental friendliness and maximum resistance to abrasion was solved. Thus, this lacquer can be used to cover surfaces with limited hardness that are subject to periodic mechanical stress (for example, a wooden floor on an open-air stage). At the same time, the service life of the coating was extended.

Acrylic-urethane (acrylate)

These substances are classified as water-soluble types, and they are positioned as universal. They are distinguished by fire safety, environmental friendliness, vapor permeability, and hence it is clear that they are suitable for any application. Nevertheless, more often they are used on synthetic fragile bases located outside, because the level of protection provided (in terms of withstanding temperature extremes and high humidity) is quite decent. Due to the fact that they use a water-soluble base, their consistency is not too thick. And this, in turn, means a reduction in the cost of covering one square meter. But a weak consistency requires the application of several layers, which indicates an increase in the drying time.For acrylate samples, it can be up to 14 days! In any case, their popularity is ensured by powerful adhesion, the ability to dilute water, the absence of unpleasant odors during operation and sufficient safety. As a result, acrylate is an excellent material for outdoor use in small architectural forms.

Conclusion

When choosing a varnish composition for outdoor finishing work, you should not focus only on the speed of its drying (so that rain does not catch the surface during the hardening process). You should always pay special attention to its protective chemical properties, because even if the varnish dries quickly, but the treated base does not receive the necessary protection, the coating will quickly collapse, and, as a result, the object itself will become unusable.
