One of the main problems of modern housekeeping is to make housing as warm as possible. It is very important to provide such insulation, so that the building does not freeze in winter, during the rainy season it does not accumulate moisture and does not require high heating costs.
It can not be said that this is such an impossible task: modern builders are able to insulate walls so much that gas consumption decreases many times. However, in order to obtain such savings, you must initially invest a lot, and not everyone can afford it.
It is very advantageous in this regard, heat-insulating plaster. Its cost price compared with the insulation of the facade and walls from the inside with foam plastic is much more acceptable. In addition, applying it does not require a lot of time and special skill. It's enough to buy good material, a tool and be patient. Those who have been engaged in construction for a long time, know that this business does not suffer haste.
Composition of thermal insulating plaster
Naturally, it is up to the manufacturer to put in plaster for the purpose of high-quality thermal insulation. Some put in it special very small balls filled with air (plaster "Umka"), others add expanded perlite (Teplover). And one and the other materials serve as a barrier that repels cold air and moisture. As cementitious components, cement and various polymers are added to the plaster mixture. As you can see, nothing complicated. However, this simplicity allows to protect the housing from cold and moisture for many years.
How to use?
In addition to its economy, heat-insulating plaster has another significant advantage - to use it, it does not have to be a professional builder.
- To begin work on warming of a dwelling by means of plaster it is necessary with clearing of walls of a dust, a dirt, a rust and fungi.
- Obligatory stage - priming of walls (from aerated concrete, brick, including plastered). Priming them is necessary to prevent penetration of excessive moisture into the plaster layer.
- If the wall is very smooth (for example, the finishing putty has been applied previously), it must return the roughness. For this, cement spraying is used: cement and sand are mixed in the same proportion and are brought with water to a semi-liquid state. A broom or a special mechanical sprinkler, the mixture is applied to the wall so that it is not less than 90% dotted. It is on these cement unevenness and will "cling" insulation.
Well, now - how to apply heat-insulating plaster. The solution is prepared according to the instructions.
- On the wall we designate the location of the lighthouses (the distance between them is 1-1.2 m) and attach them to the "lapuhi".
- Level the beacons by level and give them a good fix.
- It is possible to apply a plaster layer. "Lapuhi" is applied so that they lie on top of each other. Between them you can not leave air cushions. All pits and irregularities need to be filled with a mixture.
- Trim the plaster with a long rule.
- After the application of the first plaster layer, it must be allowed to stand for several hours.
Do not allow direct sunlight or moisture to penetrate the plastered wall. - After drying, beacons must be carefully removed, previously "cutting" them from the wall with a spatula or sharp knife.
- Formed depressions must be filled with remnants of plaster and well sanded when it dries.
So it is easy and simple to warm the walls with plaster. The main thing is good material and free working hands.
