Composite and polypropylene pools do not require additional cladding. Their coating is both a supporting structure, a waterproofing, and a decorative lining. In the case with their concrete “brothers” – another thing. After pouring the concrete, it should be plastered and then covered with two-layer waterproofing, after what you can fill it with water and swim. But this pool won’t look well. For this reason, you will need to make choices in favor of one of the available ways of facing. There are not many of them, but they must necessarily meet a number of requirements, such as resistance to ultraviolet, abrasion, loads, the effects of chemical reagents, sharp temperature fluctuations, and so on. Consequently, variants: covering of interior of the pool with polyvinylchloride liner, ceramic tile with water absorption of less than 5% and, finally, glass mosaic. If we talk about the expense component, then the least expensive coating is a liner, then, on the growth – glass mosaic and, at the very end, ceramic granite tile. Specialists of our company are ready to give recommendations, characteristics and advantages of each type of coverage. However, it should be noted that in this case, the customer should make a decision based on two factors: the price and personal preferences. As they say – every man to his own taste.
