However, than and how to cut a flat or wave slate. Fairly fragile products. For the young generation often remains a mystery. We will try to make clarity to this question.
Today, in the wake of insanity on everything environmentally friendly, the slate is considered perhaps the most dangerous roofing material. How. In its composition is asbestos, a dangerous mineral! True, the majority absolutely does not imagine how exactly this substance affects, and in what quantity it contain different objects and things surrounding us. Keep in mind if you decide to get rid of everything that the asbestos contains, immediately throw the money! In their manufacture, asbestos are used to increase the life and strength of the bills.

Before performing work on the line of the future cut, you should abundantly moisten the surface of the processed material with simple water.
