Plastering of wooden walls inside and outside the house, like plastering, technology, photo

A tree house does not always have an aesthetic appearance. The solution to this problem may be putting plaster, which gives the house a nice look. But you need to know how to plaster a wooden house outside or inside. Plaster protects wood from pests, moisture and other negative phenomena. This is the easiest and most economical option, which is well suited for various buildings of wood. It is important to properly prepare and apply the composition on the tree. Otherwise, the work carried out may not give the desired result.

Requirements for work

When working with frame buildings, various solutions can be used, for the treatment of log cabins, it is necessary to take into account the vapor permeability, elasticity and hygroscopicity of the coatings used. It is important to remember that depending on the level of moisture and temperature, the tree changes its size, so the use of hard coating is sometimes impractical. Therefore, it is necessary to strictly adhere to the technology of applying plaster to reduce the possible risks of cracks. Immediately begin to finish the walls can only be when working with ready-made frame buildings, because their walls do not bear the load, and therefore will not deform over time.

has been completed when working with reconstructed or new buildings from the timber is required to wait for the shrinkage of the erected walls and only then proceed to plastering. In the process of shrinkage, the material of the walls is compacted as a result of reduction and load of the seams. The shrinkage process takes 1-2 years, but only if the box is covered from the direct effect of precipitation. The necessary work is carried out in the period of optimum humidity and temperature in the range of 10-20 ° C. Frosts or extreme heat adversely affect the setting of the mortar directly to the base, which reduces the quality of the result.

If it is necessary to carry out interior decoration, it can be started before the completion of works with the facade. In winter, the heating system is always turned on. In this case, the use of heaters specifically for walls treated with material is strictly prohibited. Drying of all walls, both external and internal, should be carried out in natural conditions.

Plastering rules

Plastering of wooden houses can not in all cases. First you need to make sure that this type of finish is suitable for a particular case. The required layer of material is determined with a fishing line, which is stretched diagonally across the wall and the level of deviation is specified. The level can be attached to the fishing line. If the deviation is more than 4 cm, plastering the walls will not be the right decision, since it may crumble over time. If you need a layer of a few centimeters, then plastering will be fully justified. If it is necessary to finish a large surface area, it is recommended to use drywall - in this case it will be an economically more reasonable solution.

Plastering of walls begins with a choice of mortar. It is necessary to determine the correct composition and prepare it in accordance with the technology. Plaster of wooden walls inside the house with heating is carried out using lime compounds, which gives the most optimal result. Such plaster fits well and additionally acts as a heater. For non-residential buildings and exterior walls of buildings suitable composition, based on cement. It well maintains differences of temperatures and high humidity.

Next, you need to prepare the surface. This stage is very important and responsible, if the surface is not properly prepared, then the coating will not last long. At the final stage the composition is applied. The quality of this stage depends on the durability of the result and the appearance of the entire surface. Especially this item is important for residential premises.

Preparation of walls

Regardless of the type of building, plastering follows the same principle. Plaster sticks to the tree rather badly, installation of an additional support is required so that the material does not fall off under its own weight. Metal or wooden mesh can be used as a support, compensating for even minimal wall movements. This is especially true for timber buildings that shrink for a long time.The grid helps to maintain the integrity of the plaster, even if it moves away from the base a little.

The walls must be thoroughly cleaned of paint and varnish residues, other solutions, dirt, or dust, as this can significantly reduce the level of plaster setting to the wall. At the same time the glossy surface is processed by an emery paper.

The easiest and inexpensive way to increase the level of adhesion is to apply special cuts all over the wall. They are made at an angle of 45 °, they can also be made horizontal. The inset is made to the width of the ax blade, and the notch depth should be up to 1 cm. The most reliable and durable method is the use of reinforcing nets made of metal or wood. For rooms with high humidity, foam film is used as a damping material.

If the geometry of the structure is complex and makes it impossible to fully apply the factory grid of metal then it can be connected directly on the ground. Nails on which the wire fastens are driven into the wall with the necessary pitch. Wooden mesh or shingles are made of slats with a width / thickness of 20/5 mm. They are nailed to the base crosswise and create a grid. Additionally, it protects the coating from possible cracking. Coniferous wood that is not affected by rot or mold is used for shingles.

The use of shingles occurs according to the following principle:

• When working in wet rooms, a waterproofing layer made of special liquid materials, films, and the like is always used. In other cases, the walls remain intact. So that the slats do not crack, they are moistened with ordinary water along the fibers.

• The first layer of rails is nailed to the surface. They can be fastened with straight lines or at an angle, the distance between the slats is 5-6 cm. Nails are used, the thickness of which is 2 times larger than the cut. It is possible to fix at two points to tighten each rail.

• The second layer is attached under 90 ° angle, if the first was fixed at an angle of 45 °, the distance is 6-7 cm. The fastener should be more solid, since the nails will simultaneously hold the applied material and the slats.

• Nails are hammered every 15 cm. Nails are driven in in a checkerboard pattern 1/3 from the edge of the plank, which minimizes the appearance of cracks along the wood fiber.

• The rails are built up with a small gap, but not end to end. This method allows you to prevent a change in the boards. This is an additional insurance, because when changing the humidity of the board changes in thickness.

At the end of the work, a beacon profile can be mounted, if necessary. After that, you can proceed to plastering.

Preparation of mortar

Different solutions can be used for working with wooden surfaces. This is due to the fact that the tree has a fibrous structure, which increases the level of adhesion of the plaster and the base. The plaster of the wooden house inside is carried out by the following types of solutions.

Limestone and cement. At the first stage, cement and sand are mixed 1: 3, mixed, lime milk in the amount of 1 part is added to the composition. For the solution can be used as career sand and river. But in any case, his fraction is not more than 1 mm.

Sandy plaster and cement. This option is a classic and is widely used for processing walls. The basis of the solution is sand and cement according to the standard scheme 1: 3, however, the proportion of filler may vary. To begin with, dry ingredients are mixed, and then water is added. Before using the finished plaster, it must be mixed several times and left to stand for 15 minutes.

How plaster is selected for interior work, see the following video:

Gypsum and lime. In this case, used lime, gypsum and sand, their ratio should be 1: 1: 3. Sand and lime are mixed, water is added. The peculiarity of this solution is that it can only be used for indoor processing, it quickly sets, so the material is prepared in small portions. This solution is most often used for plastering shingles.

For proper preparation of plaster using lime it is necessary to extinguish it beforehand - a lot of gas is emitted in the process.It is impossible to use quicklime, otherwise the coating will crack.

Warming and leveling of walls with plaster

In houses with a log house, alignment and insulation of houses takes place as follows:

• Cells of 100x100 mm in size are made of wire with a diameter of 6 -10 mm mesh is attached to the wall. A factory grid can be used, which will correspond to the specified parameters.

• Thermal plaster is being prepared from clay, straw and sawdust in equal proportions. A cement mixer can be used for the process, which reduces time and labor costs at this stage. Water is applied to the eye, the main thing is that the solution is thick.

• The plaster layer must be a maximum of 50 mm. Above the reinforcing mesh layer thickness is not more than 30 mm. Otherwise, after drying, large and deep cracks may appear. Small cracks are quite acceptable.

After the plaster has dried, which can take several days, the surface can be leveled with cement mortar. When it is completely dry, the final stage of finishing with a special vapor-permeable material is carried out.

Application of the solution

In order to achieve maximum effect from the application of plaster, all work must be carried out in three stages.

Splashing. The thickness of this layer is not more than 10 mm. A rather liquid plaster is used, which allows to reach the maximum level of adhesion for the following layers. When the layer grabs and dries, apply a primer.

Soil. It is the main layer of plaster used, with a wall made of wood. The thickness of the layer is not more than 10 mm and depends on the general condition of the surface. The applied layer should dry well, after which it can be leveled with a covering.

Cover. The last layer, it is used for the final alignment of the base. The thickness is not more than 2 mm, the layer is smoothed or rubbed off, which allows to perfectly align the wall for the use of further decorative materials.

Clearly all the stages of work on the plaster inside the house are shown in the following video:

Finishing work

High-quality plaster on the tree inside home allows the use of other decorative materials. When finishing works with the walls of the frame structure, various solutions can be used as the finishing stage of decoration: decorative plaster, paintwork materials, wallpaper, and so on.

In other cases, when you want to maintain a good level of vapor permeability, you must use certain materials. In most cases, glued paper wallpaper, which have a decorative function and allow you to hide small cracks, which are sure to appear after plastering the walls.

You can use decorative plaster for aesthetics. It can be used instead of painting or wallpapering, it looks beautiful and original.

Conclusion

Applying plaster outside and inside the house requires adherence to special technology and the use of appropriate materials. All work must be carried out clearly with the established requirements, which will avoid problems in the future. Plastering of the walls makes it possible not only to level them, but also to warm them. The use of special materials will help to protect the walls from rodents, insects, moisture, fungi or mold. The complexity of the work of plastering wooden houses is no different from brick or concrete. However, it is necessary to remember all the features of the work and materials used. All work is better to entrust qualified professionals.
