Self-leveling floor deviceSelf-leveling flooring isis an easily spreading solution that forms a flat horizontal surface when dry. According to the composition, there are epoxy floors (especially resistant to aggressive substances), cement-based (the cheapest and less toxic), acrylic polyurethane (work well under wear, but are more demanding in terms of base preparation) and highly filled polymer (the most expensive). The main advantages of these floors are seamlessness and durability. They do not burn in fire, do not sink in water, are resistant to acids, alkalis and heavy loads. They can be used indoors and outdoors. One "but". Officially, manufacturers claim that self-leveling floors are toxic only during application (while polyurethane is more harmful than epoxy). However, in private conversations, craftsmen admit that they will not do them at home.
