Exterior stucco home - the eternal confrontation climate

On the agenda - stucco home!

house is built, and it remains only to decide whether to perform first interior trim, or more important stucco home.I must say that the final decision often influenced by time of year and such factors as weather conditions (why would you perform finishing outside walls under the rain).But, let's assume that as long as there are days are clear, it was decided to finish the finish.What kind of prefer the mixture for plastering of the walls?

As such, solutions varieties a little, but it does not mean that there is no difference which one to use.Walls, periodically moisturize because the raw climate, as well as cornices and other architectural elements, it is desirable to cover the cement or cement-lime mortar.Both of them, along with lime, suitable for exterior decoration of concrete and brick walls.

In dry climates, brick, wood and plaster walls can be decorate the clay-lime and lime-plaster solutions.Gypsum plaster for outdoor work not suitable, since it is easily destroyed by damp.

What prepared plaster for external works

To make the most primitive plaster is enough to remember the recipe of masonry mortar cement, sand and water.The only difference is the consistency, if fairly steep solution is needed to fix the brick, the better for the walls composition diluted with water to a state of sour cream .When the ratio of cement (M-400) and sand about 1: 4 to get the perfect exterior finish stucco home.

Cement-lime mortar is made almost the same, but instead of water you need to lime putty by which the composition is obtained is extremely viscous.Lime becomes loose in a ratio of 2-5 kg ​​per half a bucket of water, depending on what kind of consistency is needed solution.Cement mixed with the sand in a ratio of 1 part to 4 to 6 to 1, and then filled with mortar.

strength, curing speed and flexibility plaster can be adjusted using plasticizers.

mortar - it is not only the above-described dough of the same name, but also take some amount of sand (between 2 and 4 parts per 1 part lime).A small amount of cement (2 full trowel) significantly hardened composition.

Lime plaster solution is made with the addition of gypsum test and, importantly, a la carte, because the hardening of his starts in 6 minutes and finished in half an hour.Plastering the external walls executed and clay-calcareous composition, which is identical to the previous one, only used as an additive 1 part clay dough.For

lime-gypsum plaster may be applied retarding additives such as slaked lime in the form of dough (0.2-0.5%) aqueous alum solution (5-20%), an aqueous borax solution (5-20%).

How is plastered exterior walls

set of actions for the exterior finish any of the above solutions is fairly standard, though, if done according to the rules, scratch coat, primer and finish coat should be slightly different proportions of components.For example, external wall plastering with cement mortar begins from scratch coat, which must contain recommendations of experts from 1: 2.5 to 1: 4 cement and sand, but the soil is performed at a ratio of 1: 2 or 1: 3 of the same materials.Nakryvki same general should consist of 1: 1 or 1: 1.5 cement and sand.

But all rules rather the nature of the laboratory, which are not strictly in the home.In fact, it is quite enough to change just a little texture to the walls of spray enough liquid composition, and soil applied thicker solution.The consistency of the finish layer should be somewhere between the scratch coat and finish coat.

plaster exterior walls - the order of operations in finishing

first kneaded liquid consistency of the solution you choose, it is dipped a broom or CEILING.Then, taking his other hand a stick, starting at a small distance from the wall to knock on her broom so that the spray flying onto the surface.This will be the scratch coat.

Primer is applied with a trowel, for him to use a sufficiently dense solution as a quality rustic sour cream, in which spoon should stand. Trowel have an acute angle to the surface to grind tight plaster. This layer, depending on the chosen solution and unevenness of the walls may constitute together with the previous thickness of 1 to 3 centimeters.

finish coat - finishing coat on already flat wall, so waiting for the soil dries, prepare a solution in a liquid consistency of sour cream and causes the plaster to 1-2 millimeters thick.Having a surface uniformity, leaving the finished wall covering dry and gain strength.
