In the process of applying the solution in any way, the manufacturer's recommendations should be strictly followed. Only in this case it will be possible to create a strong, beautiful protective layer.
Work technology
Finishing work is carried out according to a certain technology. Properly performing each step, you can achieve good result even without experience in carrying out such actions.
Facade plaster for outdoor work, the price of which will be affordable for almost every owner of a house or cottage, designed to finish the base of different material. It can be brick, foam concrete, or other types of building materials. The most optimal and inexpensive way of finishing is the use of beacons.
The work is carried out in several stages. First you need to prepare the base, then the beacons are installed. Only after that you can start plastering the facade. This method is suitable for manual application of the solution. It is important to adhere to the proportions when mixing the dry mix, as well as the manufacturer's recommendations regarding the time of its drying.
Foundation preparation
Plastering of brick facades or made of any other materials must begin with the preparation of the base. If you skip this step or do it poorly enough, the result will be of insufficient quality.
First you need to remove old finish. It is beaten with a small hammer or a wooden block. Where the sound is deaf, the old finish is knocked out with a chisel and hammer. In some cases, you will need to use a hammer drill. It also removes dirt, oil stains and dust.
It is desirable to reduce as much as possible the number of irregularities, bumps on the base of the walls. If this is not done, you will have to apply the plaster in a thick layer. Material consumption will increase significantly. Therefore, it is better to properly prepare the surface of the walls than to spend money family budget for the purchase of additional dry mix.
A brick base requires, in some cases, jointing. This procedure allows you to increase the adhesion of the solution to the base. The plaster will hold tight, and the life of the coating will increase. Some builders during construction brick walls houses leave the facade with empty seams. This allows you to prepare the base for finishing faster.
For foam blocks, the jointing is not done. This also applies to walls reinforced concrete slabs"rough" masonry, in which the surface is smooth. A mesh for plastering facades is immediately stuffed onto such varieties of materials. First you need to apply a layer of primer deep penetration. It will enhance the adhesion of the solution to the base.
When choosing a primer, you should give preference to trusted manufacturers. It is also necessary to adhere to the correct concentration of the solution. In this case, the film will be strong.
lighthouses
Assumes the use of beacons. These are metal guides. They are installed on the base to indicate the level of plaster application. The rules, leveling the layer, slide their nose along the tops of the lighthouses.
It is believed that the use of this method of finishing allows even a non-professional to make a perfectly smooth surface. However, the master needs to familiarize himself with the technology for installing beacons on a plane.
It is necessary to determine the verticality of the wall with a plumb line. Deviations from the level must be determined before installing the guides. If the top of the walls is inclined in depth, this indicator must be taken into account. Beacons are customized to a certain size. The excess height of the guides must be cut off.
Installation of beacons
Produced after the installation of beacons. From the corner at a distance of 20 cm, a point solution is applied. Their diameter should be about 5-15 cm. The height depends on the intended layer of plastering. If the rule is 2 m long, the beacons can be placed 1.7 m apart. If the wall is too large, it is necessary to increase the guides.
Each beacon is installed in the solution and sunk a little there. The level rule is applied on top of each element. If necessary, the position of the beacon is adjusted to achieve the ideal vertical position finishes. To avoid deviations, errors, it is recommended to pull the "laces" between the two extreme elements during the alignment of the beacons. After the solution has dried, the voids formed under the lighthouse are filled with putty.
Applying the first layer
Plastering takes place in 3 stages. Facade plastering mechanized way allows you to perform all actions faster. However, in this case, be sure to work in a respirator and goggles. Otherwise, the solution may get into Airways or eyes.
The dry mixture must be diluted to the consistency of liquid sour cream. In this case, the manufacturer's recommendations must be taken into account. Ready-made ones are also on sale. Some professional builders recommend adding PVA glue to the solution. It will give extra strength. Putty will lie well on the wall.
The mortar is applied to the wall with a ladle. The mixture must be poured onto the base without pouring it. Roughness on top layer are welcome. After surface treatment, the solution must dry.
Base layer
The next step is the main facade plastering. To do this, you need to prepare a solution. It should be the consistency of thick sour cream. It is thrown on the surface between two lighthouses. It should be noted that the thickness of all layers of plaster should not exceed 5 cm.
With the narrow side, it is necessary to press the rule to the beacons. The tool is moved from side to side. The edges of the rule should not fly off the tops of the guides. The movement is made in an upward direction. The excess is cut off. This results in a perfectly smooth surface.
If during the alignment process it turned out that the solution is not enough, it should be added. The mixture is poured into the hole formed. Then again draw the rule over the surface.
Grout
Assumes the completion of the final stage. The surface needs to be sanded. This procedure is performed after the cement finish coat dries. For this, apply special graters. They can be made of foam or wood.
If a putty is used that is not based on cement, the manufacturer's recommendations should be followed. They must be indicated on the packaging.
Grouting allows you to smooth out small irregularities, seal sinks after applying the rule. The grout is performed in a spiral. Circular movements begin with wide movements, gradually moving the tool towards the center. WITH great circle the tubercle is stretched in the center. At reverse action it is completely levelled.
Considering how it happens facade plastering, everyone who wants to can do the procedure well. In this case, the surface will be perfectly flat. Following the recommendations of professional repairers and builders is a guarantee of a good result of the final work.
