When we are faced with the repair of a fireplace, stone stove or chimney, we have to purchase materials that can withstand high temperatures. Many people are familiar with the problem of cracks on the walls of the stove, due to which smoke gets into the room.
In building markets today, you can find various mixtures that are suitable for working with high temperatures. They often include lime and clay. But it is quite possible to prepare a heat-resistant putty with your own hands. The plus is that the materials for this need the simplest and cheapest, and in quality it is not much inferior to the purchased mixture.
I will tell you some proven, quick and easy recipes.
1. For the first recipe you will need:
- 20 grams of metal filings;
- 100 grams of clay;
- 100 grams of chamotte powder.
Combine all the components, mix well and add a salty solution to the resulting mass. The consistency of the mixture should resemble thick sour cream.
2. The next option for homemade putty consists of clay, sawdust and wood ash.
All this is mixed and diluted with a saline solution in the proportion: 1 part of water and 6 parts of dry mass. To achieve the required thickness, the putty is diluted with diluted vinegar.
3. Universal Putty Recipe
Take a handful of slaked lime and combine it with 100 grams of flaxseed oil. Cook the mixture until it reaches a suitable consistency. Then we spread it with a thin layer and wait until it dries. It turns out a solid putty, before using it should be heated with a lamp or fire.
The easiest homemade putty recipe
Once this recipe was published in a Soviet magazine. The resulting lubricant is capable of withstanding simply enormous temperatures. To prepare it, you need asbestos cardboard. In general, any type of asbestos will work, be it fiber, cord, etc.
It is necessary to grind the asbestos to small fractions by grating it. Always use a respirator and gloves when working. You can even just tear the cardboard into small pieces. Then we mix asbestos with liquid glass.
People of Soviet hardening are more familiar with the name "stationery glue". You noticed, I do not name any exact proportions, since there are none. You need to get a mass similar to plasticine, kneading easily in your hands.
After hardening, it will resemble ceramic. Such a homemade putty does not conduct current and practically does not conduct heat, i.e. it is quite suitable as an insulator. In addition, the mixture has excellent adhesion to metal.
