The appeal to specialists has another undoubted plus: they know the features of the compositions for bulk floors of different manufacturers and offer the best option. For example, domestic products are much cheaper than produced abroad, although other qualities have a great resemblance. However, the cost of almost the same mixtures and domestic manufacturers may vary markedly. But cheaper, does not always mean better. Quite often, in order to reduce the cost of a bulk floor, which is most often given at the rate of 1 kg, some companies add a heavy filler, such as a barit, thereby increasing its consumption by each square meter. As a result, the buyer purchases more expensive products.
