I would like to note a high-quality approach to work. The ease of communication and the responsibility of the staff have made cooperation with you very pleasant! I liked the openness, they won't impose it just to sell it. They will tell you, tell you, advise you. Efficiency with delivery . Nice prices.
I would like to recommend you..but everyone chooses for himself who to "be friends with"! I definitely made a choice for myself, if I need something, then come back to you!
Sensible specialists were able to competently explain how to solve my question on finishing. It was necessary to glue porcelain stoneware onto fiberboard, purchased a separation membrane so as not to "farm" with LH or silicone. Additionally, I purchased a waterproofing membrane for the installation of a heating cable.
