Self-leveling roofs are distinguished by their high performance, which explains their high popularity, especially when arranging flat or slightly inclined roofs. The most optimal angle of inclination is up to 3%, in which case it contributes to the minimum consumption of material, without leading to its runoff to the edges. Also flat roof is safest. How to equip self-leveling roofto move workers, in this case, insurance can not be used. If the inclination angle exceeds 3%, in this case, additional reinforcing materials are laid to keep the mastic from spreading. The most permissible roof slope for the filling method is up to 25%. The type of base may be wood, concrete, cement, metal, etc.

The process of pouring the roof itself is quite simple, the main thing is to adhere to the following recommendations:

• Work is allowed at air temperatures from +5 to +30. The weather should be dry, without rain and dew.

• Preparation of the base includes its cleaning from dirt and old exfoliating materials and drying. A cement-sand mortar or a solution of primer-bitumen and kerosene can be used as a primer coating.

• The first layer is hot mastic, consisting of asbestos, stone powder, small gravel. This layer performs protective functions, and the material consumption varies in different situations: if the roof is new, then it takes about 8 kg / m2. At repair work the expense is twice less.

• For mixing mastic substances, it is best to use a drill with a nozzle, since the solution must acquire a uniform composition. You should also take into account the rapid hardening of the fill, so it must be consumed without delay.

• The process of applying mastic should be started from the lowest parts of the roof - near gutters and grooves. If the roof area is large, then it is best to use a special apparatus, spraying the substance with a uniform layer. In other situations, it can be applied with a mastic with a brush, or by pouring it onto the substrate, level with a spatula or roller.

• Each subsequent layer is poured after the previous one has dried.The optimum thickness of each layer is no more than 2 mm. If required by the technology, the required reinforcing material is laid between the layers.

• After applying the final layer, a mixture of stone chips, gravel and coarse sand is poured over it to create protection. To make the roof decorative qualities, as well as to increase its ability to reflect the sun's rays, after its drying staining is allowed. Along the perimeter of the roof reinforce the additional application of mastic and reinforcing material.
