Wood is an excellent material for building a house, warm, breathable, eco-friendly and very beautiful. But only the untreated exterior walls after a couple of years darken, are covered with cracks or, even worse, with mold and moss.
A wooden house, like a fence, gazebo, canopy, must be protected from atmospheric influences, fungi and mold. This can be done with several means: lacquer, oil, paint. The first two retain the color and structure of the tree. If you want to radically change the face of the house, or the tree has already darkened, you need to resort to paint help, having previously familiarized yourself with the main types of this popular coating.
When choosing a paint
For painting the house outside is used wood paint for facade work. In addition to protection from moisture, it will prevent the appearance of mold, spoilage by insects. Quality paints are resistant to sunlight, and bright fresh color persists for several years. The same coating, according to GOSTs should last at least 5 years.
The amount of paint needed for painting the house is calculated simply if you know its spreading rate - consumption per 1 sq.m.surface. To do this, the area of the walls of the house that are to be painted, is multiplied by hiding power and by 2 or 3( depending on the number of layers that the house is to be painted on).It is better to buy the paint with a margin, since in a year or two there may be a need to tint some areas, and the paint of the same color from one manufacturer will have a slightly different shade, which is quite acceptable for different batches.
Basic types of paints
All facade paints can be divided into 3 groups depending on their basis:
- acrylic,
- alkyd,
- oil.
Acrylic paints today have become virtually the standard in Europe, including in the northern countries, where they paint more than 80% of all houses. This is an eco-friendly material, based on water, and acrylics as binding elements. This paint does not have a sharp unpleasant odor, allows the tree to breathe, since it does not cover the pores, while at the same time reliably protects it from moisture. The coating is resistant, resistant to severe frosts, and bright and fresh colors persist for years. In addition, the paint of different colors is perfectly mixed, and you can get almost any shade to the taste of the owners.
To work with acrylic paint simply, it is applied by roller, brush or by means of a spray gun - spray gun. It dries quickly, and if necessary, the coating can be refreshed without resorting to preliminary cleaning. Coverage of a quality paint will last for an average of 5 years, and in favorable conditions - up to 10.
When buying such a paint in the winter, it is worth remembering that storing it at minus temperatures is strictly impossible, as it will be irretrievably spoiled.
Alkyd paints came to the market earlier than acrylics and are still in demand due to the low price. When they dry up on the surface of a thin film is formed, which has the ability to repel water, which increases the protective properties of this paint. However, because of the rapid drying and, consequently, less penetration into the layers of wood, this coating is less durable.
Recommend alkyd paint can be used for painting windows, doors, thresholds - those parts of the house that are best protected from moisture. Also this paint is known for its frost resistance and the ability to transfer temperatures below -30 degrees.
Alkyd paints, unlike acrylics, are applied only on a completely dry surface, as otherwise bubbles and peeling are guaranteed. Dries one layer - 8-12 hours.
Oil paints today are found almost exclusively with domestic manufacturers. They are made on the basis of drying oil and toxic, have a sharp unpleasant odor, and on the surface often formed by staining. In addition, they are more expensive than modern analogues, due to higher prices for raw materials.
Drying coating of oil paint for about a day, and for better work quality should be carried out in dry, cool weather. It should be taken into account that when painting with oil paint, the surface will have to be tinted only with it or cleaned to the base, since no other paint over the oil will lie down.
