Stucco the walls with your own hands with video. Installation of lighthouses, application technology

Like all classics, good work plastering is based on "three whales" - high-quality surface, the composition of the plaster and the presence of accurate beacons.

First, evaluate the plastered surface. It should have sufficient strength to hold the applied plaster. The surface should not separate and crumble. Plastering over the old plaster is not recommended, because in the old plaster, defects can be hidden, which will only appear after the new plaster has dried. As a result, you have to remove everything and start again. Website repair apartments with their own hands will reveal the secrets of the plaster walls, after that you yourself can do it at home. A video example at the end of the article.

Internal gypsum plaster of walls with own hands

If the base surface is a conventional brickwork, it is permissible to use the plaster mixture on the cement. This is the best option. It turns out cheap and it is allowed to overlay thicker layers( for brick walls it is often necessary).But, if a layer of more than 20 mm is applied, the plaster must be reinforced with plaster mesh. When internal gypsum plastering of walls is done - priming a brick wall is not needed, if there are no oil stains and dust on the wall. So plastering ordinary building bricks.

If it is necessary to plaster the facing brick, then the situation is more complicated. Here you will have to use special primers and fittings. The technology is rather complicated and will better invite experienced professionals to this work. Due to the smoothness of the surface of the facing bricks and their small porosity, the plaster does not adhere well to the surface. As a result, the plaster composition is peeled off by pieces( sometimes together with a grid), which fall out. Even if the reinforcement is done qualitatively and pieces of plaster do not fall out, cracks will soon appear on the surface of the plaster.

For plastering a smooth concrete wall, a plaster composition on a gypsum base will be required. In this case, the priming of the base surface is mandatory. The best plaster compositions on gypsum are those in which quartz( sand) particles are contained, which give a smooth surface a slight roughness, which will ensure sufficient adhesion of the plaster to the surface. Gypsum plaster is reinforced with a polymer mesh with cells 5x5 mm.

When plastering rough concrete, both cement and gypsum compounds are used. Rough concrete must also be primed, but it is possible to use a primer without quartz particles. Suitable primers offer "Starateli" and "Glimsa".

For the plastering of foam concrete surfaces it is better to use gypsum compositions, but cement ones are also allowed. But the primer is necessary, and not simple, but the so-called "deep penetration".

Pile-gypsum plaster blocks, from which the partitions are made, are best plastered with gypsum compositions with preliminary treatment with a conventional primer.

After evaluation and preparation of the base surface and selection of the plaster composition, it is necessary to set up beacons.

Installation of beacons on the wall for plastering

Beacons in construction - guides that help level the surface with liquid formulations. For stucco beacons are used perforated profiles in the form of T-roll. The width of the profile depends on the thickness of the applied plaster. Special beacons are good in that they do not need to be removed after the plastering is finished - they remain in the thickness of the plaster. So then you do not have to close the depressions after the removal of the lighthouses.

The installation and installation of lighthouses on the wall for plastering, requires special care. First, the whole room is checked to find out the deviation of its geometry from the correct shape. This is done with the help of a gon, a plumb bob, a rake level, a long rule( at least two meters) and roulettes.

Corner check the correctness of the angles between the walls. The verticality of the walls is verified by a plumb line. The smoothness of the surface is checked by the rule. The slat level verifies the slopes of horizontal surfaces and is used as an auxiliary tool for testing the slopes of walls. Roulette is needed to accurately measure the amount of deviations determined by other tools. Roulette can also measure the diagonals of the room - if the diagonals are not equal to each other, then the room is not rectangular, and the corners in it are not straight. After the completion of all measurements, a decision is made to set beacons. This can be a change in the shape of the room to give a correct geometric or simple alignment of the unevenness of the walls - everything depends on the tasks pursued by plastering.

The walls are completely primed before installing beacons. Beacons are placed on the quick-hardening mortar or on the one that will be made plaster. Vertical stripes of solution are put on the wall, into which beacons are inserted. Before the solution hardens, beacons must be leveled in levels and heights. The distance between the beacons is set so that the rule used rests with its ends on two neighboring beacons and has the possibility of a small movement over them, without slipping from them.

How to apply plaster on walls, the technology of applying

The plastering technology is quite simple. Between the neighboring beacons a surplus of solution is poured onto the wall of the trowel( this is called "namet").After namet rule, based on neighboring lighthouses, the solution is spread out from the bottom up.

Professional plasterers for namet use "falcon".It is a flat platform with a handle at the bottom. On the site, the plaster solution is applied in a volume much larger than when using a trowel. Holding the falcon in one hand, the plaster trowel in the other hand dumps the solution from the falcon to the wall. This technique provides higher labor productivity. The technology of applying plaster to the wall is not cardinal, you can throw in the solution as it will be convenient for you. Here are ways to quickly plaster the walls of the hopper with a bucket.

To make a thick layer of plaster, first make a rough nest without alignment over the beacons. As soon as this layer dries and loses mobility, you can make a finishing nest and align with the described method.

The solution applied and stretched over the beacons is dried and rendered as a grout, that is, the plastered surface is ground to remove minor defects. This completes the process of plastering walls with gypsum mixtures. Now we offer to watch the video lessons that we picked up on this issue.
