How to choose a primer for the fence?

A new house is built, now it remains to establish a fence, enclosing its private territory. The fence is the same decor element as other exterior items. To give beauty and integrity to the design, it is necessary to choose the right material and color of the fence that harmoniously fit into the landscape: it can be a metal profile, brick, wood or concrete. But in any case, so that the paint does not peel off after the first frosty winter, a primer is needed to protect the fence.

Features of the choice of soil for the fence

The primer will not only provide a smooth and economical application of decorative paintwork on the base, but also, correctly selected, will provide a long service life of the fence, its presentable appearance. The choice of primer mixture depends on the characteristics of the material, its structure:

  1. Fence from corrugated board. Beautiful, durable, easy to care. In this case, only columns and bearing parts require additional processing. Profiled sheets themselves are covered with polymer decorative paint, which guarantees a long service life. After a few years, the coating may lose its original appearance, then corrugated board can be painted.
  2. Fence made using metal sheets. In this case, the columns and surfaces are completely primed before painting. It is imperative to use a mixture with a corrosion-resistant coating - they will give reliable protection against corrosion and rust.

Picket fence

  1. Wooden picket is a natural, durable and beautiful material, but it requires special protection. Wood surfaces are primed with compositions with the addition of antiseptics that protect against moisture, fungus and mold. Additionally, flame retardant treatment can be performed, providing fireproof properties.
  2. Concrete fences are one of the most durable and popular. They are quickly erected, the material is inexpensive, but the porous structure of concrete easily absorbs water, collapses under the influence of atmospheric phenomena, and the gray color looks boring. Properly made primer and subsequent concrete fence painting able to extend his life, turn into a decorative element. Mineral-based primers are best suited for concrete - they fill the porous structure of the base well, significantly reduce the ability to absorb moisture, and ensure uniform application of the topcoat.
  3. Brick fences, due to the diversity of structure and color, are beautiful in themselves. They do not require additional decorative staining. But the brick has strong moisture-absorbing properties, under the influence of precipitation it can quickly collapse. For its long service life it is better to use transparent soils that do not require subsequent application of paint.

Special primer for wood

The fence posts may be wooden or metal. For wooden poles, the soil is used the same as for the main part of the fence, and metal ones require additional corrosion protection.

For mixed surfaces, universal formulations suitable for different types of material can be used. Before processing the metal poles, it is necessary to apply an additional anti-corrosion coating that protects against rust.

What to consider when choosing

When selecting soils, it is necessary to consider:

  • profitability (consumption per 1 m²);
  • toxicity - for the external fence this factor does not play a very big role, but work with such mixtures will need to be carried out using protective equipment;
  • compatibility of the primer base and decorative paintwork.

The composition of the primer can be:

  1. Mineral. Their basis is lime, cement or gypsum. Well suited for stone, brick and concrete. Before applying them, it is not necessary to completely dry the surface.
  2. Acrylic, water-based, deeply penetrate the base structure, quick-drying and economical. Universal.
  3. Alkyd (synthetic) are used only for priming metal or wood, form a durable water-repellent film on surfaces. Treated with such a composition, the metal poles will stand for a long time.

Outdoor alkyd primer

In addition, when choosing a soil, weather conditions typical for the area should be taken into account:

  • temperature fluctuations;
  • amount of precipitation (if there are frequent heavy rains, then you should buy with maximum water repulsion);
  • strong winds and other factors.

Primer Stages

The technology of applying soil to the surface of the fence depends on the material from which it is made, but there are general rules:

  1. All work is carried out in warm, dry, calm weather.
  2. The fence must first be thoroughly washed; you can use a home car wash for this purpose. Particular attention should be paid to the junction of pillars with fencing sheets, because it is there that the most accumulates dirt. They are best cleaned with a stiff brush.
  3. After that, a thorough inspection of the surface is carried out, all minor damage is eliminated, traces of corrosion and rust are removed from the metal, potholes and large cracks are smoothed out using putty.
  4. All greasy stains are removed with degreasers (white spirit, gasoline). If you neglect degreasing, then the adhesion of the soil to the base in these places will be fragile.
  5. Having eliminated all the shortcomings, it is advisable to wash the fence and poles repeatedly and allow to dry.
  6. Depending on the material, soil is selected and applied to the fence using a spray gun or roller. All posts and joints are treated with a brush for better protection. The first primer layer is made more liquid - this helps to smooth out small potholes, microcracks. After drying, immediately apply a second and subsequent layers.

After such processing of the fence, the paint will lie in an even layer, it will hold firmly.

Taking the necessary time for your fence, you can get a fence that not only hides privacy from prying eyes, but also harmoniously fits into the landscape, emphasizes the beauty of the facade. Properly performed in compliance with all stages of the work, priming will help to maintain a beautiful view of the fence for a long time, he will not need the next cosmetic repair soon.
