Application of plaster layers.

Grout better layers, ie, the surface sequentially, with some interruptions, causing layers of plaster - spray, primer and finish coat. At one time to put a thick layer should not be, as it can slide in the process, and after drying cracked. Solution can throw or spread, using different tools. Anointing is available to all, but rather smeared thick solution. Throwing a lot harder because it requires certain skill. You can throw any solutions. The first layer (spray) is applied throwing, it can not spread, since it from a liquid solution. If a masonry or concrete surfaces are made accurately, then they can apply thin layers of solution thereby obtaining a thin render: on the brick surfaces of 5 mm and above and on the concrete up to 5 mm. If the plaster on the brick will be thinner than 5 mm, then through it may raying welds of masonry in the form of cells that can not paint no lime, no glue painting. Plaster on wood surfaces must be at least 20 mm, measured from the packed output drann. Thinner layers are not recommended: they will shine through drann, and when it will be a slight warping of plaster to crack. First, on the surface causing a continuous layer of scratch coat - throw liquid creamy, which is well flow into the rough and uneven, firmly adheres to them and clings to the surface, holding then his subsequent layers of the solution. Thickness of the scratch coat 4-5 mm for stone and concrete walls and up to 10 mm - for timber. The solution was to throw a hawk with a trowel for plastering. That he lay down evenly, it is necessary to gain the same amount of solution, and throw with the same distance. In his left hand holding a falcon shield up, and the right - plastering trowel. With the Falcon solution take the end or the right edge of the trowel away. Sketching on the wall should be an abrupt movement of the hand. This operation requires preliminary training and the first attempt may fail. Spray is not leveled, except when necessary to remove the individual clusters of the solution, speakers from the general plane of the plaster. After the spray harden, it applied a second layer gallop - the soil. For him prepare a thick (pasty) solution. Soil - the main layer to identify, provide the necessary thickness of the plaster, leveling bumps on the surface. When required a thick plaster, primer is applied in several layers. However, the thickness of each layer should not exceed 15-20 mm, as thicker layers slide. Lime-plaster thick quick-solutions can be applied thicker layers. Each soil layer is applied when a previously deposited layer sufficiently hardened, does not crumble under pressure on his finger, and most importantly, do not slide off the wall, followed by a layer of gallop. Soil can throw a trowel and then leveling rule or spread through the falcon. When buttering the lower part of the falcon with a solution close to the wall at a distance equal to the thickness of the plaster layer and the upper part is separated from the wall at 100 mm. Sokol move upwards. As it moves the solution lies on the surface and the upper part of the falcon is gradually approaching it. Similarly, put a solution on the ceiling. In this case, one party hawk trowel pressed to the ceiling, and another separated from it by a distance of 50-100 mm. The last layer of soil is well aligned, as clobber him hard. If you have previously deposited layer of soil was dry, it is recommended to drench with water, and only then apply the next layer of soil. This gives the solidity of the plaster, as the layers of the solution is better grapple with each other. The final layer of plaster (with improvement after the first layer of soil, with high quality after the second soil layer) is nakryvka. Cause it after setting the soil grouting and smoothing mortar layer of fat no more than 2 mm. It is very important to make sure that the solution for the finish coat does not come across coarse sand, which, when grout and healing will leave a furrow. To this end, the components of the solution should be to sift more carefully, using sieves with mesh 1,5 x1, 5 mm. Primer before applying nakryvochnyh layer is moistened with water and a brush. The solution was applied to the surface with a trowel and level poluterkom wavy movements from the bottom up. After a bit nakryvochnyh layer dries should begin grouting. It is best to overwrite when a plaster layer is floating, but still wet. For the jointing of a grater to take the right hand firmly pressed against the plaster and move across the surface in circles. The individual mounds are cut off by a float, cut solution gets into the grooves, thereby leveling the surface. If you still remain after the grout shell, we must add a solution to the grater and overwrite them. Setting time of the solution depends on its composition, humidity and porosity of the plastered surface, air temperature, the thickness of the deposited layers. The following are recommended time intervals between individual operations: when plastering lime-gypsum mortar each subsequent layer is applied to predschuschy within 7 - 15 minutes, with cement mortar in 2-6 hours, with mortar - after the whitening, but incomplete drying of the previous layer.
