There are no ideal surfaces after the erection of a brick or concrete structure. Any surface requires subsequent alignment of it with the use of various technological methods. Without plastering work is indispensable.
But the work can not only be simplified, but also greatly simplified, made available to any newcomer.
Plaster works are divided into simple, improved and high-quality.
For the execution of simple plastering work, there is no need to use any additional technological devices.
But to achieve an improved or high-quality surface when plastering is possible only with the use of tools.
The most demanded device, the so-called plaster profile beacons.
Special metal zinc-coated guides of a certain profile, made of steel with high corrosion resistance, are called as beacons for plastering walls.
Installing beacons under the plaster, the plaster gives a level indicating the thickness of the laying of the plaster layer, which provides the required flatness of the surface.
The main advantage of using beacons is that the plastering work on the beacons with their own hands can be performed by an employee who is not highly qualified.
Characteristics of the beacon profile
Available in the form of a special shaped profile with holes. The profile is L-shaped or T-shaped.
The length of the profile is 3.0 m.
The height of the shelf in the T-shaped profile is 6.0 and 10.0 mm. T-shaped profile is available in widths of 20.0 and 18.0 mm.
The advantages of setting a beacon profile are:
- low price;
- ease of use;
- the ability to form thermal seams that prevent the appearance of cracks when temperature changes;
- there is no need for dismantling at the end of work;
- the use of the profile reduces the layer of plaster mortar.
Preference should be given to qualitatively galvanized metal profiles with increased rigidity.
Than to fix profiles to the surface?
Profiles are installed using a plaster solution or self-tapping screws.
For quick and efficient installation of beacon profiles for plasters, professionals use special fasteners called "ears."
To install a profile beacon under a 3.0 m plaster, at least 7 fixing points must be installed.
How to install beacons for plaster with your own hands
Lighthouses for plaster are installed on a dry, non-frozen surface.
Before installing the profile with your own hands, the surface is cleaned of paint and dirt. A deep penetrating primer coat is applied. This is especially true when working on the ceiling or floor.
Option 1
- If you plan to coat walls by lighthouses without dismantling the latter:
- measure the height of the room;
- cut the profile of the desired length;
- having receded from corners by 300 mm, draw vertical lines;
- with a step that is less than the length of your rule, draw vertical lines along the entire wall;
- on vertical lines, near to the corners, apply a plaster solution with a thickness equal to the height of the beacons( the step of the stucco piles should be chosen from the calculation of 40. .. 50 cm, but not less than 7 anchor points for the 3.0 m profile);
- solution is applied with a trowel, sharply striking against the surface;
- the profile is pressed into the plaster mortar while checking its verticality in all planes;
- first of all, the profiles nearest to the corners are set;
- at the bottom and at the top of the profiles nails are hammered into a solution that has not yet frozen;
- when the solution hardens, cords are drawn up and down between the nails at the top and bottom, parallel to the floor;
- horizontal cords and vertical profiles form a plane;
- , intermediate profiles are established in the formed space with a step smaller than the length of the rule, limited by cords and beacons;
- it remains to apply a layer of plaster and with the help of the alignment rule;
- work starts from the bottom and goes up.
Option II
If you are planning not to light the beacons. This approach is recommended for economical and thrifty. This method is recommended for use in rooms with high humidity.
What should be done:
- measuring the dimensions of the room, it is necessary to cut the beacon profile of the required length;
- vertical lines with a step of 2.0 m are applied to the wall;
- installation of the profile starts at one of the corners;
- the first profile is pressed into the scraps poured onto the wall from the plaster solution by the back side( convex part into the solution);
- requirements for profile attachment points similar to the first option;
- it is desirable to fasten immediately the two nearest profiles, adjusting the position using the level;
- excess extruded solution immediately removed;
- when the solution in the beacons solidifies, plastering of the surface is carried out using the techniques described in the variant;
- beacons are easily removed after the end of the application of the plaster layer, and the grooves are covered.
Variant III
If you plan to perform the plastering of walls without the use of profile beacons.
Professional finishers use a technique that does not require the installation of profile beacons. Look closely at the video offered.
And you can do the following:
- , retreating from the corners of 80. .. 100 mm, clogged self-tapping screws, which with the help of levels set the hats in one plane;
- to the hats around the perimeter of the string, forming a rectangle;
- with a step smaller than the length of the rule draws vertical lines and screws are screwed, whose hats do not go beyond the imaginary surface of the contour;
- solution is applied to the places of vertical lines, slightly covering the hats of self-tapping screws;
- to the vertically applied solution is applied tightly a rule, tightly supported on the screws of self-tapping screws;
- do not forget to pre-wet the rule with water;
- removing the excess solution with a spatula, the rule must be sharply removed;
- the beacons are obtained from the plaster mixture;
- further impregnated plaster on the walls on the beacons with their own hands.
Variant IV
Stucco walls with own hands without beacons.
Wall plastering without installing beacons is possible if there are no high requirements for flatness of the surface.
The main advantages of plastering walls without beacons:
- the plaster solution is saved because of the less thin layer of its laying;
- reduces the time for work related to the preparation and installation of beacons.
The plastering algorithm is simple:
The plaster solution is applied and the excess is removed by the rule.
In the grooves of the solution will be more, on the elevations less.
Work order:
- before plastering, apply a layer of acrylic primer to the surface using a wide brush;
- primer should dry thoroughly;
- gypsum solution is recommended to dilute in small portions until the consistency of thick sour cream is obtained;
- solution should be prepared as much as you can work out within half an hour, more gypsum solution does not live;
- , with the help of the rule, level the surface, removing the excess solution.
Conclusion:
- you choose one or another variant of plastering walls by yourself, considering your abilities.
The issue of the need to remove beacons can occur when plastering rooms with high humidity. In the premises of this type it is better to use the second variant of applying the plaster.
The variant allows to use beacons at imposing of plaster and their removal after hardening of a solution.
It is not necessary to remove the packs in dry rooms if you use a quality, well-galvanized beacon profile.
