The decoration plastering walls and ceilings - one of the final stages, aiming at leveling the surface before painting or wallpapering.The process is time consuming and requires certain skills, so ideally, of course, it is best left to professionals.However, if you have decided for economic reasons to learn how to plaster yourself - nothing unattainable in this desire is not, you only need to take a thoughtful and thorough process.You will see that each square meter you get better, and you are more satisfied with themselves.So, how to plaster a wall?
Any plaster - it is diluted with water to the desired consistency, a mixture of sand and binder, which is used as cement, gypsum or lime.Cement plaster should be used where increased humidity, for example, in the bathroom.In dry living spaces more preferably gypsum or lime plaster, allowing the walls as possible to "breathe."Please note the room environment before deciding how to plaster a wall.The retail chain has a wide selection of ready plaster mixtures, however, the mixture can be prepared independently.The proportions and the consistency of the solution depends on the purpose for which layer is intended.
plastering divided into three layers: the scratch coat, primer and finish coat.
the rendering - the lower layer to ensure a secure bond with the material of the wall plaster.The solution requires mobility, so for consistency it should be similar to a thick cream.The soil needs to be done thicker: the solution must not "swim" and crawl under their own weight.The same consistency is done and finish coat.
Before plastered walls, preparing the surface: thoroughly cleaned of all superfluous and install "beacons" - wooden slats or sections of galvanizing, which can be purchased at the store."Mayak", the thickness of the respective layer thickness, are set strictly on the level at a distance from each other to the above rule (a tool that you will flatten obryzg) overlaps the two adjacent "lighthouse".Where between the "beacon" and the wall there is a gap, the gap must be filled with a solution, or to enclose wedges.
can now be ready to start the rendering.Lightly moisten the surface of the walls and the spaces between the "lighthouse" with a trowel, a trowel or a special bucket sharp movements rub solution, moving from top to bottom.Shot Power needs such that the wall constitutes "pancakes" instead of bumps, thick obviously stands for "lighthouse".Take a right and, at an acute angle (40-45) firmly pressing it against the "lighthouse", level layer, removing excess solution.After the solution will seize, remove the beacons of emptiness and is embedded solution zaravnivaem.After this layer has dried up and stopped to crumble, finally clobbered its wooden float and proceed to the primer.
primer is applied in 2-3 layers, the thickness of 6-8 mm each.Impose a solution on the trowel over the entire width and bottom-up "deliver" on its wall.Of course, everyone should be given the previous layer to dry before applying the next.The last layer before the finish coat is necessary to moisten the same as before the plaster wall.
finish coat is applied to a thickness of about 4 mm.After it dries the grout made wooden float.Pressing grater against a wall, move it in a circular motion over the entire surface.And the last - smoothing spreader with rubber-covered work surface.Smoothing first vertically, then horizontally, and the wall - is ready.Once completely dry, you can paint or paste.
thermal insulation plaster is different from the normal composition of the primer layer.In the solution as a filler instead of sand included sawdust, pumice stone, slag or the like (lightweight and porous) material.Especially in dealing with such a solution is not, except that increases the mixing time.
