Nowadays, it is increasingly possible to see houses whose facades are decorated with foam. In a harsh climate, warming plays an important role. And the foam - is one of the materials with which you can make insulation and align its walls. In this article, you will learn how to finish the facade and how to select the right material to perform such an important task.
Each type of decoration has its own advantages and disadvantages, reckoning with which you can successfully cope with the facing of the external walls of the house.
Many homeowners decide to finish the facade of the foam due to the fact that the material is affordable, especially when compared with other finishing materials for outdoor use. In addition, the foam has a high thermal conductivity, it does not freeze even at very low temperatures. Not susceptible to changes in temperature and does not rot.
Polyfoam is not afraid of moisture, so when installing it you do not need to lay a waterproofing layer.
This type of finish is reliable and durable, it retains its original appearance for a long time. Among the advantages of the material, it is worth noting that it is easy to assemble the foam. And this is important, because in this situation you do not need to spend money to pay for work.
As for the foam plastic defects, the most important of them is that rodents can live there. In addition, when overheated, the foam releases toxins that can be harmful to health.
Although it is easy to veneer the facade with foam plastic, but, as in every case, you need to prepare for the working process before proceeding to the implementation.
In order not to be interrupted during the finishing process home foam, try to prepare all the tools and material in advance.
Before you go shopping for a material, calculate the area of the walls. After that, determine the desired amount of foam. You will need:
At the first stage of work it is important to correctly prepare the base surface of the walls. On how well you do this work, will depend on the durability of the finished walls and the quality of thermal insulation.
First, clean the surface from the old finish. To do this, remove from it the old layers of paint and whitewash. If the old coating is peeled off somewhere, it should be cleaned, removing it with a chisel and a hammer. All trim elements must be removed.
Clean the surface of the old finish
The expanded polystyrene is fixed against the walls. This implies that there should not be any bulges greater than 2 cm on them. If the bulges still remain, then remove them.
The next thing to do is to treat the walls with an antiseptic that kills fungi. Even if their external manifestations on the walls are not observed, do it anyway for the sake of prevention. Determine the zero point. This line will be the original for the installation of foam. This determines the appearance of the structure. But, more importantly, this event will prevent the occurrence of condensate. The label should overlap the floor level in.
If the dew point is not correctly determined, moisture will build up in the house, which will subsequently cause a characteristic unpleasant smell of mold. If you do not want to create a hotbed for fungi and mold, then take this process seriously.
As a result, you should have one solid line around the perimeter of the house. Ideally, this line should go parallel to the ground. To achieve such results, use the hydraulic level. For drawing the equal line use a kapron thread and level. Now you can proceed to installation work.
The most important stage of work is the installation of foam plastic. Attach the base plate along the intended line.
The basement not only helps fix the foam, but also protects against the penetration of rodents from the bottom of the house.
The process of home insulation with foam plastic
If you do not have the opportunity to purchase a plinth bar, make the edging a wooden bar or a starting profile of metal. If you decide to fix the foam on a wooden beam, then before fixing it on the facade, treat it with special antiseptic agents.Thanks to this, you protect the material from the formation of mold and fungi on it. In addition, this event will extend the life of the product. Then cut the bars of the right size. Punch holes and fix them on the wall with dowels, aligning the position along the measuring cord stretched along the wall.
After that, proceed with the installation of the first row of foam. Apply special glue to it. Make additional fasteners with plastic fungi. As you have probably understood, the facade of the house is decorated with foam plastic from the bottom row. If you have not yet formed a picture in your head, then watch the video, where you can see all the processes described clearly.
After the glue has been applied to the foam, press it against the wall surface. Then make a hole using a perforator, and make an additional connection with a plastic fungus. There should be at least five such fixing points. Fix foam panels in a staggered manner. In this case, there will be less cold bridges.
Seam processing can be started only after the glue has completely hardened. Now you need to seal the seams. If they are not larger than 5 mm, then seal them with foam. If wider, they should be filled in with a foam polystyrene insert. If the surface is not very smooth, with a curvature of 5 mm, then remove the excess with a grater on the foam.
When gluing foam in 2 layers, it is important that the second seam does not fall on the previous one. Incidentally, in this case, the seams of the first layer do not need to zapenivat.
Plastering on foam
At the final stage must be decorated with decorative trim. It involves the plastering of the surface and its subsequent painting. Before you begin to plaster the walls of the house, glue the construction mesh to the foam. It is attached to the glue. Only after the glue layer is completely dry, proceed to the plaster.
Some experts glue the mesh immediately on the plaster. In any case, dock it should overlap, at least 10 cm, and not end to end. To level the corner and make it less vulnerable, install a special perforated corner.
After applying the finishing layer of plaster and drying it completely, apply a primer to the walls. And then finishing work - painting in any suitable color. Now facing the facade of the foam is completed. In order not to harm health and work with comfort, install reliable scaffolding along the walls.
