Facade plaster for outdoor works, the price of which will be in the hands of almost every owner of the house or cottage, is designed for finishing the base of various materials. It can be a brick, foam concrete, or other types of building materials. The most optimal and inexpensive way of finishing is the use of lighthouses.

This method is suitable for manual application of a solution. It is important to adhere to the proportions when mixing a dry mixture, as well as the manufacturer's recommendations regarding the time it dries.

Substrate preparation

Plastering of brick facades or made of any other materials must begin with the preparation of the base. If this stage is missed or performed insufficiently qualitatively, the result will be insufficiently qualitative.

First you need to remove the old finish. It is beaten with a small hammer or a wooden bar. Where the sound is deaf, a chisel and a hammer knock out the old finish. In some cases, you will need to use a percussion hammer. Also remove dirt, oil stains and dust.

It is desirable to reduce as much as possible the number of irregularities, hillocks on the base of the walls. If this is not done, you will have to apply a thick layer of plaster. The consumption of material will increase significantly. Therefore, it is better to prepare the surface of the walls correctly than to spend the means of the family budget to purchase an additional dry mix.

Recommendations for preparation of the foundation

The brick foundation requires, in some cases, jointing. This procedure allows increasing the adhesion of the solution to the substrate. The plaster will hold tight, and the life of the coating will increase. Some builders at the construction of brick walls of houses leave the facade with empty seams. This allows you to prepare the base for finishing faster.

For foam blocks do not do the ripping. This applies to the walls of reinforced concrete slabs of "rough" masonry, in which the surface is smooth. On such a variety of materials, a mesh for the plastering of facades is immediately filled. Preliminary it is necessary to put a layer of a primer of deep penetration. It will strengthen the adhesion of the solution to the substrate.

When choosing a primer, preference should be given to proven manufacturers. Also it is necessary to adhere to the correct concentration of the solution. In this case, the film will be strong.

Lighthouses

предполагает использовать маяки. The technology of plastering facades involves the use of beacons. These are metal guides. They are installed on the base to indicate the level of application of the plaster. The rules, leveling the layer, slide with a spout over the tops of the lighthouses.

It is believed that the use of this method of finishing allows even an amateur to make an ideally smooth surface. However, the master must familiarize himself with the technology of installing beacons on the plane.

The verticality of the wall must be determined by the plumb line. Deviations from the level must be determined before installing the guides. If the top of the walls is inclined inward, it is necessary to take this index into account. The beacons are adjusted to a certain size. The extra height of the guides should be cut off.

Setting beacons

производится после установки маячков. The facade is finished with plaster after installation of beacons. From a corner at a distance of 20 cm put a point solution. Their diameter should be on the order of 5-15 cm. The height depends on the intended layer of plaster application. If the rule has a length of 2 m, beacons can be installed at a distance of 1.7 m from each other. If the wall is too large, you need to take in the guides.

Each beacon is placed in a solution and a little bit of it is heated. A rule with a level is applied on top of each element. If necessary, the position of the beacon is adjusted to achieve the ideal vertical position of the finish. To avoid deviations, errors, it is recommended, during the alignment of the beacons, to tighten the "shoelaces" between the two extreme elements. After the solution has dried, the formed voids under the beacon are filled with putty.

Application of the first layer

Base layer

. At the next stage, the main plastering of the facade is carried out. To do this, prepare a solution. It should be a consistence like thick sour cream. He is thrown to the surface between two lighthouses. It should be noted that the thickness of all layers of plaster should not exceed 5 cm.

The narrow side is to press the rule to the beacons. The tool is moved from side to side. The edges of the rules should not fly off the tops of the guides. Movement is in the direction upwards. Surplus cuts. This results in an ideal smooth surface.

If during the alignment it turned out that the solution is not enough, it should be added. A mixture is poured into the formed pit. Then again follow the rule over the surface.

Grout

предполагает проведение завершающего этапа. The plastering of the facade involves the completion of the final stage. It is necessary to make a smooth surface. This procedure is performed after the cement finishing layer has dried. To do this, use special graters. They can be made of foam or wood.

Carrying out grouting allows to smooth small irregularities, to seal the shells after applying the rule. Grout is performed in a spiral.
