variety of innovative finishing materials is difficult to compete with the old ways, the centuries-old practice proven successful.How many would not appear fast, lightweight, advanced technologies finishes, a leader of ratings remains plaster.Despite the complexity, the dust, the mud building, long-term process, we, like our ancestors, plasterers wall with his hands.We are not afraid of the complexity of the work is important because the final result and a long list of priorities, practical characteristic of wear-resistant plaster.
plaster allows to realize almost any design projects.This is the best option to eliminate flaws builders to align the walls and create a stucco patterns manually.It is used to form a variety of textures, colors and surface struct
Wizard finishes possess a number of specific technologies for applying plaster mixture to the wall, so that the material is transformed into a democratic broken natural stone, sawing rock or a conventional clutch.According to the degree of expressiveness and Venetian plaster terrazitovye can compete wallpapers and finishing with 3D structure.A number of colorful variations and combinations of different application methods of poultry-kilometer fancy decorators grow wings.
undeniable merits plaster ↑
Choice plaster mixtures as a finishing material-founded superiority of their operational, technical and aesthetic qualities, the exact height of the entire aggregate set of indicators.
priority list plastering appear:
- water-repellent qualities of the material, the ability to dry out after soaking disaster without loss of decorative figures;
- optimization of the insulation characteristics of the structure;
- aeropronitsaemost, that is, the ability to pass the excess of domestic vapors, preventing premature aging and wear of materials, thereby also set a favorable balance to stay in humid premises;
- meet sanitary and environmental standards;
- opportunity to change subsequently textured and colorful concept decoration;
- flammability from which prefer plaster for facade and interior decoration implementation of wooden buildings;
- reasonable cost of repair, especially palpable when executed plaster walls with his own hands and applied the most affordable price in relation to the compositions.
list of negative aspects ↑
Despite the compelling list of arguments in favor of applying plaster on the walls, from this material has a number of disadvantages.
- in violation of technology and the application of the plaster mixture non-compliance with the time required for curing may cause cracks and other defects;
- exterior finish can only be done at zero temperature;
- for application to the wall with a smooth and glossy surface will require pre-treatment, primer, installation-mesh netting, special notches;
- low productivity of labor-intensive work;
- building restrictions on the power of the plaster layer.
The disadvantages of plaster can also be attributed unnecessarily complicated process of finishing of wooden houses, the need for complex training.The ability to recognize the negative side of the textured plaster "absorb" the dust hoarding in relief recesses.This negative characteristic of the material, composed of large sand particles.True, the plastered surface can be cleaned with almost all currently existing household chemicals.To eliminate the need for frequent maintenance is better to cover special varnish, natural or synthetic wax.
wet process: application technology Traditionally ↑
plasters are applied consistently performed three layers, each of which performs a specific function.
- obryzg - first layer, providing adhesion to the surface finishing materials.For its application apply solutions to the consistency of thick cream.The power applied to the wood layer should not exceed the size of 9 mm, in the processing of foam concrete and brick walls 5 mm.The rendering is spread only on flat concrete surfaces to comply with the equivalent thickness.
- Ground - the second layer is performed with a solution with a thicker consistency is applied after the hardening of the previous scratch coat.Reminiscent of the dough solution leveled and overwritten until a relatively flat surface.Ground determines the thickness of the plaster, serves as a basis for final finishing.
- nakryvki - the final stage of production of plastering work.For the third top layer solutions are used to fine-particulate carefully sifted sand.Before applying plaster, which resembles the consistency not too thick cream, dried up the soil is moistened to improve the adhesion between the two layers of plaster, then performed a careful alignment of the surface.
Before performing each stage of plastering is necessary to wait a period regulated construction standards and recommendations of manufacturers of ready mixes.
Future plasterers, interested in the question of how to plaster the walls under the wallpaper or a different type of lining, you must know that in violation of the technology made the whole work will be in vain.The plaster is peeling off, crack and upset artists other negative phenomena.
Compositions for plastering walls ↑
In almost forgotten past, the components for the production of plaster mixtures were sand and cement binder.Now there are plenty of ready-made compositions, formulas are fortified with various builders.These components affect the ductility, adhesion, curing rate, the ability to cure at a certain temperature.With the introduction of the modifier of plaster convenient to breed and cause.Only the cost of the finished plaster mixtures not everyone has to acquire.For adherents of the budget repair schemes and finishes prefer practical cheap cement compositions and the most popular gypsum plaster.
materials made of cement differ significantly from gypsum plaster mixtures, both methods of application, and on the specific characteristics affecting the scope.
plasterers wall with cement mortar ↑
main components of cement plaster are sieved through a river or sea sand and cement with a variety of traditional enhancing additives.Fractional size, talking about the largest grains, determines the possible thickness of the plaster layer: the thinner the dispersion of the material, the thinner the layer of plaster can be done.
method of preparing a solution of commercially available ready-mix is extremely simple.The capacity of 7 to 8 liters, or half-filled with water, which then is added in portions during the dry part of the regular construction mixer or stirring by hand trowel.Wishes to save can make a cement mixture on their own.This will require the cement commonly used brand M400 and sifted clean sand in a ratio of 1/3.
undesirable to increase the share of the primary binder, due to violation of proportions may be reduced during solidification.Then, the executor will be difficult to promptly and carefully smoothed to smooth the surface.
for "blotches" on the wall of cement plaster required trowel or spatula to level poluterok or rule for smoothing trowel.Inexperienced finishers, for the first time dared to plaster the walls with his own hands, it will be enough to float and trowel.
Not for nothing in the circles of professional plasterers overlay technique called grout blotch.A solution with a spatula should really biting slap into the wall.Only then the solution is well stick to the work surface, as the smallest of its particles under the influence of shock forces can freely penetrate the upper layers of the building material.Movement plasterer nashlepyvayuschego solution resembles the movement of the player in ping-pong around splashes, dirt, but they will have to accept to obtain optimum adhesion.
Fill once a large segment of the wall is not necessary, it is better to start finishing part, the area of which does not exceed one meter.Having finished "obshlepyvat" planned site, you can begin to equalize.It is done in a circular motion float against the clockwise direction.In the process of equalization void solution is added, the excess material removed from the wall and are sent back into the tank with the solution.Cash layer of grout dry for at least 7-8 hours, then plops the next layer.
Smooth angles make using edged boards fastened with screws to the wall adjacent to the treated surface.And when the need to plaster the adjacent wall, the board is not nailed, and fix the struts.In order to form a geometrically accurate usenok (concave corners) are fastened together by two at a right angle trowel.Beginners plasterers need to remember that any excess solution, and all the flaws must be addressed in a period not exceeding 12 hours.After this time, remove the hardened solution will be problematic.
As plaster wall plaster solution ↑
Plaster mixes, also called alabaster compositions have been created to facilitate the work of plasterers.They easily applied, fast cure, but inferior cement mixture on the characteristics of strength and durability.
There are mandatory requirements: alabaster solution diluted in perfectly clean containers, clean tools applied, since the presence of impurities can reduce the process of solidification.
performers do not need to own specific tricks.Gypsum plaster is easily applied to the walls simple movements using a trowel, spatula or trowel.To prepare the mixture you need to read the manufacturer's instructions and to follow its recommendations.Plastic material is spread on part of the wall, then leveled a rule or a large spatula.Alignment is performed first in the vertical direction and then horizontally.Dries layer plaster for 2-3 hours.
Smooth corners formed reinforced angular device, after which the crushing of the elementary plane is corrected with a spatula.Within an hour after the start of the curing process is necessary to remove any excess plaster with which not always have time to handle the newcomers.Among the shortcomings of the finishing material is marked poor compatibility with oil paint painted surfaces, bad to go to Alabaster and plaster.Hand made plaster walls in such cases may fall off due to the fact that during the solidification of the plaster solution starts to separate moisture.It was she who causes flaking plaster on a glossy surface and changes the percentage of moisture in the putty.
Finishing beacons ↑
For potential plasterers who want to learn how to plaster the walls under the wallpaper, interlining, tiles and other finishes on beacons, description of technology may be too confusing complex process.In fact, everything is much easier than it might seem frightened unusual terms inexperienced person.Technique is really easier to learn on the video course, but instruction in the simplest alignment method using metal profiles can be useful.
need more typically a length of 2 meters or more, screws, plaster or concrete solution, plasterer tools and metal profiles, produced now by the manufacturers of finishing materials and technological devices.They are not too cheap, but they are much smaller than the services of professional plasterers, moreover, will help to better and faster job done.
- last beacons (vertically mounted rails) is conveniently located at a distance of 20 cm from the intersection of the partition with an adjacent wall or end wall.
- To identify the surface curvature of the walls or load-bearing wall in the vertical level used or primitive string with a weight at the end.
- along a vertical rules are put in 20-30 cm plaster lumps.
- By crushing rule of hillocks formed an imaginary level, which will be oriented alignment process.
- position is fixed beacon solution.
- similarly exposed next beacon.
- to determine the exact position of the intermediate beacons, if they are needed for the surface of a large area, located between the flush points beacons stretch cords.As intermediate devices, denoting future plaster surface, use screws driven into the wall flush.They need to be removed after completion of the work.
- Once hardened mortar used for fixing the beacon, "zashlepyvayutsya" gaps between profiles.
- to the lighthouse is pressed against the rule and if the rails are aligned plaster.
rule along the rail profiles is moved in the vertical direction, occasionally alternating with light turns from side to side to create an even layer.After drying plaster beacons break out of the wall remaining from their grooves carefully embedded solution.
There is a method of applying the solution by lighthouses.Quite simply this is done and plaster walls with his own hands: a video guide and the story artist will help to master plasterer profession artless science and a little different, however, a labor-intensive technologies.
Plaster - a complex form of finishing, but to cope with it can totally inexperienced person.You must be patient, study the manual thoroughly and accurately fulfill all the requirements.Under these conditions, flawless surface and a perfect result will be a long time to please the owners of the premises.
