Stove stoves - key moments
Plastering the stove is necessary with the mind. Do not think that if you know how to apply plaster on the walls of the room, it will be time for you to cope with the stove with a stove: the stove is a very artful thing. To the grief-master did not have to later, cursing everything in the world, picking up fresh plaster by pieces, he should know several important things.
- It is best to use a solution based on clay or lime with the mandatory addition of asbestos. Complex solutions based on cement are also suitable - but do not forget about asbestos( or other reinforcing material, for example, straw or hemp).
- Do not rush out the freshly built stove, allow the masonry to harden properly! Stucco brick oven does not accept rush.
- Plaster should be put on a special base - metal large-mesh network .This is another way to strengthen the plaster layer and give it more viability in conditions of constant temperature changes.
- If you decide to paint the stove after plastering, do not use oil paints: the linseed oil in the composition burns and generates unpleasant odors when heated.
The main problems with stucco furnaces are associated with constant temperature changes. The stove heats up - the plaster also heats up, the stove cools down - and the plaster behind it. Not every material can withstand such jumps, so it is very important to properly prepare the mortar for the stucco.
How to prepare a mixture for plastering of furnaces
The main materials for the preparation of stove plaster are clay and lime, the most popular solutions are lime-clay, lime-plaster, cement-clay. To strengthen the plaster in the solution is usually added to any reinforcing material: asbestos, fiberglass, straw, hemp. For some reason, the popularity of salt is used, which allegedly gives strength to plaster - but its utility has not been proven by anyone, so many masters treat this method skeptically. On the other hand, the danger of asbestos for human health is widely known. In general, the question of the best reinforcing material is still open.
The glue sand mortar should be prepared in a 1: 2 ratio, 1: 2: 1 cement-alumina( clay: sand: cement), lime-clay - in the same proportion, replacing the cement with lime. In all these solutions, 1/10 part of asbestos is added. You can also use gypsum - without forgetting that it quickly hardens and quickly seizes.
How to properly plaster the oven
Before proceeding to the stucco of the stove, it must be properly built and cleaned of dirt. Further, the hot surface of the stove is moistened, and on a pre-prepared metal mesh( slightly spaced from the oven itself) into two or three layers, a mixture for stucco stoves is applied from top to bottom.
Each of the layers of plaster has its name and serves for certain purposes.
The first layer is called spray .It is necessary in order to smooth out all surface irregularities, it will hold all the plaster. The thickness of the spray is 3-5 mm.
The second layer is primer .Prime the surface immediately after the base is grasped, for this use a solution, similar in consistence to the dough. The thickness of the soil is usually the same as the spray - 3-5 mm.
The last layer is called cover and is intended for final leveling of the surface. Its consistency differs from the second layer - the coating is more liquid, due to which it flows into all cracks and irregularities. Cover enough to put a layer of two millimeters.
Among other things, when stucco stoves there is a question with the plaster of the corners. In order for the angles to turn out to be even and strong, they usually use rails designed in accordance with the building level. As soon as the solution seizes, the slats can be removed and, if necessary, correct the irregularities.
As can be seen from this article, stove has a number of specific features and requires a professional approach in everything from preparation of the solution to the actual application. If you follow all the rules and follow the instructions accurately, the stucco oven will last a long time and no temperature changes to its plaster will be terrible.
