We give specific examples. The use of such insulation material as a foam leads to a rise in work by about 90-100 rubles on each square meter of surface. And, say, tile glue helps to increase the price of rubles by 80. Similarly, it affects the size of the cost and the need to dismantle the old coating, if there is a suspicion that a fungus has started in it. As a rule, the cost of dismantling is 100% of the price of installation work.
