Decorative plaster on wood: how to apply?

Many property owners are thinking about the question of why to trow down a wooden house. But do not forget that wood is a fairly vulnerable material, which is why reliable protection from negative external factors will not hurt. As one of the effective methods of protection is plaster on wood. It can be purchased in finished form in a construction shop or manufactured independently.

Why wood plaster

In order not to plaster the house after its erection, it is possible to use a special beam during construction, which is impregnated with chemicals at the production stage, which does not make it environmentally friendly. Such houses are more attractive in appearance. However, if a beam was used for construction, which was not previously processed, then it will have to be plastered after the completion of the work. This will protect the material from mold and rot, as well as damage from rodents and termites.

When to plaster

The material does not crack, there will be no crevices on its surface and in the structure, cold and damp will not penetrate the inside of the house. However, in order to protect your home, it is important not to overdo it. If the frame houses can be plastered immediately after the roof has been made, the log building of the logs must survive a year after completion of the construction. To start any work better and at all in 1,5 years. During this time, shrinkage of walls will occur, the protective layer of plaster will not be covered with cracks and will not lag behind the surface of the facade.

Kneading mortar for plastering wood

Plaster on wood should be properly prepared. Wood possesses high qualities of adhesion, that is why different types of mixtures can be applied to it. These include sand, cement mortar, lime plaster and decorative gypsum mortars. If you decide to use cement mortar for plastering, it can be prepared from 1 part of cement and 4 parts of sand. The components are mixed in a dry form, and after obtaining a homogeneous mass, water can be added to them.

Lime-cement mortar is prepared from 1 part of the lime paste, the same volume of cement and 3 parts of sand. The harder the solution is, the less sand is to be added. Such a plaster on wood has some features of cooking. It is important to observe separate mixing. In a separate tank, cement and sand must be connected, lime dough is separately diluted, which must have a consistency of lime milk. To obtain the last component, the extracted test volume must be diluted with the same amount of liquid. Milk is used to dilute mass from cement and sand. Such solutions are not afraid of moisture, so they can be used for plastering inside and outside the premises.

Plaster on wood is often made of lime and gypsum. A solution of three parts of the lime mortar and part of the gypsum will be obtained. For convenience, you can prepare a classic lime mortar, as well as carry out separate mixtures with gypsum. A large amount of such a solution should not be cooked, because it quickly hardens. Gypsum is usually used for internal works, where high performance requirements are imposed on the performance characteristics of the surface layer of walls. In order for the composition to acquire color, you can add color pigments to it. After you have decided whether it is possible to apply plaster on a tree, you should find out that to give it a special effect on the dry surface, apply wax mastic with glue CMC.

How to apply plaster

If you have not prepared the necessary set of tools and have not carried out preliminary works, then repair will not be possible.

For the necessary work, you should prepare:

• Plaster grid or shingles;
• Mixing tank;
• Concrete mixer;
• Shovel;
• Rule;
• Graters;
• Lighthouses;
• brush;
• Twine;
• level.

Caulkong caulk

Before you apply the plaster on the tree, you must protect the cracks. If the house was built out of logs, then it will be possible to find holes and cracks in its walls, which are preliminarily caulked with mineral wool or a pack. If there are large depressions between the logs, they can be filled with wooden slats, in which case the consumption of the solution will decrease.

Shing and beaconing

Before you will be painted facade plaster on wood for outdoor work, you need to stuff shingles. These works include the installation of wooden 5-millimeter rails, the width of which is 20 mm. If there is a circular saw, then cut the workpiece yourself from any board. The elements are packed into two layers. The first are installed at an angle of 45 ° with respect to the horizontal surface. The distance between the blanks should be 5 cm.

The second layer is laid on top of the first at a right angle to it. As a result, it will be possible to obtain a mesh even pattern. Before the external plaster on the tree is carried out, the shingle must be wetted and installed. This will reduce the cracking of wood or its splitting. In some cases, this reinforcement method is replaced by a plaster grid. However, the mixture layer should be quite massive, so reinforcement should be made reliable.

The thickness of the plaster layer should be determined from the second shingle layer. This parameter varies from 15 to 20 mm. In order to ensure a flat surface, be sure to use beacons. It is necessary to fill them from corners, setting a fishing line at the proper distance from the surface. Its evenness should be checked by level.

Spray and primer

As a protection of the walls, you can choose decorative plaster. The tree will protect this method. In the next step, the main solution will need to be sprayed, but it must have a more liquid consistency. Sometimes 200 g of PVA glue on the bucket is added to this mixture. If you do not have experience, then you need to start the spray with your hand. Once you adapt, you can use a trowel or trowel.

Throwing a solution on the walls, you should get a 10-millimeter layer. All cavities, irregularities and depressions must be closed. To begin work it is necessary from above, gradually moving downwards. It will be more convenient and practical, because reverse order can lead to overmoistening of the lower layer. The surplus of water will drain down. Align this layer is not necessary, but you need to navigate the lighthouses, removing the excess rule.

Even with the advent of more modern materials for decoration, decorative plaster is often used. The tree on the wall provides for this kind of protection. At the next stage, it is necessary to primethe walls, which involves applying a second layer of plaster. It is necessary to conduct work on a slightly dried layer, however, the spray should not be over-dried. The thickness of the primer is 7 mm or less. With the help of these manipulations it will be possible to level out all the irregularities and seal the cavities.

Recommendations of a specialist

As soon as the plaster dries, what will happen in four days or less, you can carry out the finishing grout using an emery cloth. It is important to leave the plaster layer for self-drying, do not use artificial drying, as this can cause cracks. The house can be heated, but walls can not be dried with a building hair dryer. For the same reason, their freezing is not allowed. That is why the application of facade plaster should be carried out in autumn or spring.

Application of fixing coating and grouting

In order for the external plaster layer to look attractive, it will need to be treated with a fixing coating. The solution for this is prepared from the same mixture, which must have a liquid consistency. The mixture is filtered through a mesh and applied with a 2 mm layer. Once all the main stages of the work have been completed, and the plaster has dried, it is treated with a grater, which must be moved round. If necessary, the place of grouting can be wetted.

Methods of applying plaster on wood

Gypsum plaster on the tree is applied after mixing the main components. However, the dye can be added to the ingredients at the preparation stage, it is introduced in a proportion of 1 to 10. Sometimes the colorant is added to the finishing solution. There is another way of giving a shade surface. To do this, the solution with the dye is diluted in equal proportions, and in the final works chaotic uneven smears the composition is applied to the working surface with a sponge or roller. Use for this you can and a special gun.

The application of building materials usually takes place in two stages. First, the mixture is poured by the trowel, leveled with a roller or brush, and after drying the surface it is given the necessary appearance. Decorability can be achieved by the speed of movement of the instrument and by the force of pressing it. The solution should be applied in one direction - bottom-up or circular motions.

Cement plaster wood will last much longer. Its application can be carried out with a broom or a stick. The tool is dipped into the solution, and afterwards it is struck 25 cm from the wall. The stick must be kept parallel to the machined surface. To get the same invoice as a result is quite difficult, so work must be done with care, never hurrying.

Conclusion

If you still can not choose which composition to use for plastering wooden walls, then pay special attention to the gypsum mixture, which has many positive features. After processing the walls with this composition they do not lose the ability to breathe.

As for cement mortars, they have advantages over gypsum. The advantages are frost resistance and moisture resistance, so cement is often used as a basis for the formulations that are supposed to be used for finishing the facade. Due to the fact that the preparation of wooden walls for the plastering process is laborious enough, many consumers purchase pre-treated timber for building a house. It does not require additional finishing, and the construction looks more attractive than the one that was covered with cement, lime or plaster solution.
