With the advent of total gasification furnace steel traditional perceived by us as a relic of the past.Special innovations finishing almost developed, but in vain!Furnace - a reliable heat source, do not suffer from shortages of electricity supply and energy prices (gas, diesel fuel, pellets).Today there was a revaluation of values, new demand services Pechnikov, recovered almost forgotten secrets furnace finishes.If you decide to put in order the old furnace or a new plaster, inevitable question proper selection of mortar, because the requirements for finishing materials are high - the plaster will be repeatedly heated afterwards.It is important that the substrate be environmentally friendly - when heated can be allocated a variety of toxic compounds, which is unacceptable, in addition, the plaster must possess elasticity and good conductivity.Consider the various options for the composition of the plaster to the question "what to plaster furnace" has found the only correct answer.
purpose of plastering oven ↑
Firstly, plaster furnace gives a neat appearance and decorates the interior pomescheniya.Vo Second, plastering increases the strength and tightness of the furnace laying.Indeed, over time due to temperature differences in the masonry cracks through which the room can penetrate smoke, which adversely affects not only the interior (sooty walls, curtains and furniture), and most importantly - it is dangerous to health.
Cost numerous heat-resistant materials presented on the shelves of the supermarket building is much higher blends traditionally used for plastering the clay ovens.Can plastered oven glinopeschanym solution with the addition of cement or lime or lime-plaster solution.Most often used by other solutions on the basis of clay.Plastered brickwork can only after full cure to prevent shrinkage (about a month).The percentage of ingredients in solution glinopeschanom differently.Everything depends on the fat content of clay.If a high rate of fat - 1 part clay will need 4 parts sand.In order to increase the strength of the plaster in the solution are frequently added additional components: fiberglass or asbestos.
As plastered oven ↑
Prepare by the rules ↑
First of all, you should properly prepare the surface: clean from dirt, dust, residuesthe old solution.In order to improve adhesion of the solution with brickwork recommended additional cleaning seams to a depth of 5 to 10 mm.The seams recommended hammer nails (40-50 mm) with a pitch not greater than 15 cm, so that they protrude outwardly approximately one quarter length.It is desirable to treat the surface specially designed for such purposes, a primer.In order to create additional surface roughness (for the strength of the connection) should use a fiberglass mesh.It is attached to the masonry by means of a liquid layer rastvora.Oshtukaturivayutsya a hot wall.
process of applying the solution ↑
solution is applied in stages (layers).Before applying the plaster be sure to moisten the laying of water.The first layer of plaster must be made liquid, creamy consistency.After curing the first layer may be applied to a second thickness up to 1 cm after the second grabs layer can begin to equalize poverhnosti.Posle the solution was slightly seize, can wipe the surface.Before grouting is necessary to moisten the plaster with water and then wipe in a circular motion all the bumps using a grater.If after drying visible cracks should expand them, moisten with water, fill the solution and, after drying, to jam.
What is better to use plaster ↑
By kiln plaster special requirements.Compositions for plastering mortar furnace are substantially different from conventional cement-sand mortar for plastering the walls of houses.This is due to the fact that when heated masonry furnace has the ability to expand and secure connection is extremely important that the plaster was elastic.In addition to the furnace well and heated quickly room plaster furnace must have good thermal conductivity.In order to impart such properties of the solutions are added various components: clay, fire clay, asbestos, glass, salt.They are used as a simple clay, as well as complex solutions that can be made with their own hands or buy ready-mix in the store.Examples of common formulations of mixtures consider in Table 1.
depending on the fat content of clay component ratio of the solution may vary.The clay fatter, the more sand required.The order of mixing the solutions about the same - first of all mixed dry components, adding the mixture to a solution of lime or clay.For additional strength bucket glinopeschanogo solution, you can add 200 grams of salt
Consider recipes commonly used formulations for the plaster: part clay, part of lime paste, one-tenth of asbestos and two parts of sand laid simultaneously.The mixture should be mixed thoroughly and gradually add water, bring to desired consistency.
Another recipe solid plaster (mix only drawback - the need for quick use, because an hour after cooking the mixture is unfit) into two parts of sand need to take one of the clay and cement (type 400 or 500).First, from the water, clay and sand is necessary to knead a stiff dough, and then enter into the composition of cement and asbestos, add water and mix thoroughly.The density of the solution should be smetanopodobnoy consistency.
Any structure must include binding aggregate and water.Binder may be represented by a single component or a mixture (e.g., cement and lime).If you decide to use a mixture of high-strength gypsum-based note an important feature: the mixture hardens very quickly (over 6 minutes).After half an hour, such a mixture is no longer suitable for use.

selecting one of the above-mentioned composition of the mixture recipes for plaster, or using a mixture of purchase, make sure the quality of the preparation of the solution.Properly prepared solution should be easily and evenly applied to the clutch, also smoothing problems should not be.Important compliance proportions - adjust the viscosity by adding water does not exceed the rate of sand - suffer the plasticity of the solution.
