Significance and features of the plastering of walls on lighthouses
In addition to simply decorative functions, plastering of external walls improves their thermal characteristics, the surfaces receive additional protection from weathering and increased fire resistance. In addition to purely utilitarian purposes, an attractive role also plays an attractive appearance. To obtain a flat wall it is better if plastering is carried out along the lighthouses. Such a flat surface accumulates less dirt and moisture, self-cleaning, etc.
The applied layer lasts longer on the substrate, less susceptible to the damaging effects of precipitation and temperature changes. Depending on the base for plastering, the technology of plastering on beacons allows the use of special laths in the form of thin slats made of wood up to three centimeters wide, packed on wooden walls or ceilings. Planks sometimes called shingles and fastened with rhombuses, bars, with a side of up to six centimeters.
Such a grate can be replaced with a metal or plastic reinforcing mesh. These techniques are justified for differences in the levels of the surface of the plaster wall from ten mm. High-quality plastering of walls under the beacon is carried out taking into account the minimum thickness of the layer, and its thickness, in turn, should not be less than a centimeter under the tile or 0.5 centimeters under the wallpaper in the thinnest place.
Of course, you can perform wall leveling with GCR systems, but the loss of area and ceiling height is not justified in any room. In addition, plastering can be done quite easily on lighthouses with their own hands, which reduces the cost of work, considering the possibility of using ready-made plaster systems with matched layers and specified characteristics. But also the use of formulations prepared according to the recommended recipes alone is good.
We prepare the walls and the
tool With a little work experience, installing the beacons for plastering will be an excellent way to get a guaranteed level surface. Before starting work, you need to prepare some tools. Traditionally, you need a plaster blade, a construction trowel is also suitable, it is convenient to use a scoop to spray a large area.
Also needed: a falcon( a rigid plate 0,4 x 0,4 m with a handle from below) for a set of working portions of a solution, a grater( with a working surface, felt) and a half-meter( up to one meter), a wide brush or brush, a sponge,rule with a sharp edge( better metal to the height of the room), a cord nylon, a building level of 2 m.
Requires a screw-dowels length of 4 cm or more( depending on the height of the installation of lighthouses for plastering), an electric drill withfunction of the perforator, hammer, screwdriver under the shape of the slotted screws, maCoeur or pencil. Before starting work, the wall must be prepared. Such preparation includes its thorough cleaning, dust removal. Then, a wall marking is performed to determine the fixing points for the beacons under the plaster.
Marking of walls for plastering on beacons
Such work consists of marking the wall, starting with drawing a vertical line at a distance of 0.4 m from the corner( the edge of the wall), checked by level or plumb. From the ceiling and floor, the distance is also not more than 0.4 m. The upper and lower points, and the middle of the received line will allow to correctly determine the required places before installing beacons under the plaster.
Through them and the middle of the first vertical will be horizontal lines, verified by the level and plumb line. At a distance of no more than 80% of the length of the metal rule with a sharp edge, it is necessary to draw another vertical line, guided by the technique for carrying out the first vertical.
With a long wall length, it is evenly divided into segments, the distance between which should not be greater than the specified length. This requirement is due to the need to align the layer with the existing rule.
After drawing of vertical lines from corners of the received rectangle it is possible to spend diagonals. With correctly executed markings, they intersect at a point located on the middle vertical, which is simultaneously a line of symmetry. Thus, at the intersection of verticals and horizontals are the locations of the lighthouses. There are enough videos on the Internet, where in the video mode the installation of beacons for plastering is shown in detail, even with preliminary markings.
In fact, this is a fairly simple operation, although it requires careful execution. An important point in the preparation will be how to put beacons under the plaster in height. At this stage, there is no depressions and hillocks on the future plaster layer. This will need the cord mentioned above. It is pulled between the screw-dowels screwed into the extreme points of the marking. Through the entire length it should not touch the wall.
After that, you can start applying lighthouse pyramids from the working solution. The heap of the solution is pressed against the top of the pyramid with the rule bar until it stops in the beacon screw. Then the plastering of the walls can be carried out along the lighthouses, the video after the article shows how the superficial solution is conveniently removed by the sharp edge of the rule.
It should be noted that the first spray layer should be about 5 mm. Then the main soil layer is applied. The number of layers depends on the required thickness of the entire plaster, but it is not recommended to put more than ten mm at a time. The primer layer can be covered with a finishing layer and smoothed with smoothing or rubbed, depending on the need for further work.
