The use of refractory bricks is not a guarantee that made it stove or fireplace will last long without cracking. Equally important, the solution to which you are laying. Heat resisting ready mix in bags is quite expensive, and working abilities are no better than simple cheap solution, which can be done by hand. Wanting to save money without sacrificing quality, it is possible to make heat-resistant mortar mix independently on the basis of cheap mortar MSH-28 and liquid sodium glass.
- sodium water glass;
- mortar MSH-28.
The cooking process heat-resistant solution
Liquid glass must be mixed with water in proportion 1:1. The components are well mixed under agitation in the bottle. The right amount of diluted liquid glass can be prepared at once, and pour it into the solution as needed, as it does not lose its quality.
Next, you need to shut the MSH-28. Need to apply mortar yellow, not gray. The latter is necessary for other proportions. 25 kg MSH-28 flows 6.5 liters of water. Water is filled from the top and made a slight pause, so it soaked into the mortar. This will prevent the formation of lumps, which otherwise would have had a long break. The mixture is stirred with a mixer until smooth and leave for at least 3 hours for the swelling clay. It can be easily left for the night, she did not grab, and on the contrary will only get better.
After the swelling of the mortar is mixed again. Then poured in 250 mm solution of liquid glass with water. Thereafter, the mixture was mixed with a mixer for at least 3 minutes. Immediately pour 125 ml of liquid glass is not necessary, as the stirring it into a thick mass to a uniform consistency will take a lot of time and effort.
After waiting 20 minutes, it is necessary to mix a solution and it is ready for use. When used topically, it gets very convenient for laying consistency. The solution is not floating, it is not overly thick. Put him is a pleasure. Although the solution and is slow, but if work properly plan, it will not create inconveniences. Possible in the evening to shut in the water for 25 kg bag of MSH-28, and then in the morning as needed to domeshivat in his water glass and to develop. Such a solution is guaranteed to be heat resistant and easy to operate, moreover, it is not expensive, what can be said about the purchase prepared mixes.
