Materials for flooring
The main purpose of underlayment – to level the surface on which will laying the finishes. According to established for decades manufacturing techniques, the slabs, serving the bases for floors in serial houses, made smooth with only one side – side that would be a ceiling of downstream apartment. The side, which should be the floor is always uneven, with mounds and hollows, often sticking out of it ends of the metal reinforcement rods. In addition, variations in floor level in the apartment can reach 10 cm. Even for nonprofessional it is clear that on this surface cannot be quality laid any covering.
According to European technology for finish floor leveling are used special self-leveling underlayment – the so-called self-leveling floors. Under this flooring for additional noise and heat insulation often put a layer of Styrofoam, and for extra waterproofing on top is laid polymer film. This floor dries much faster than ordinary screeds (for example, LC-15 dries within 15 hours after laying). Directly onto self-leveling floor can be laid tile, laminate and carpeting. To lay a parquet it is necessarily to lay a plywood. In addition, self-leveling floor has a layer of very small thickness (up to 6 mm), which is especially useful in homes with low ceilings. Excellent qualitative of these floorings made them very popular.
The assortment of dry mortars Polimin includes 3 types of floor underlayment (SC-3, SC-5 and pouring underlayment LC-2) and 6 kinds of self-leveling floors for different types of loads and operating conditions (LC-4, LC-5, LC-8, LC-15, PP-2 and TP-5).
IMPORTANT! When laying the floorings in a multiple material types, keep in mind that the strength (grade) of each subsequent layer must be lower than the previous!
