Self-levelling height compensation of floor surfaces indoors

The quality and appearance of a floor covering are largely dependent on the properties of the substrate. Unfortunately, these often do not meet the requirements for receiving a top covering. With a floor self-levelling compound, such as weber.plan 813-25, floor coverings can be optimally levelled and thus prepared for the installation of a top cover. The use of a suitable levelling compound should be matched to the respective application. Weber offers appropriate products for various applications.

Simple & safe to the goal

Substrate preparation

1. First, the load-bearing substrate is treated with the primer weber.prim 801 in case of absorbent substrates or weber.prim 803 in case of non-absorbent substrates.
2. Direct contact of the screed with the adjacent building parts (all walls and upstands like pillars, columns, etc.) must be prevented by installing an insulation foam strip.
Application

1. The floor self-levelling compound, e.g. weber.plan 813-25 (1 - 25 mm), is mixed with a suitable stirrer according to the processing instructions.
2. The levelling compound is poured, starting at the lowest point of the substrate.
3. Finally, the levelling compound mixed material is uniformly distributed to the required layer thickness with a flat trowel, a flat rake (such as weber Großflächenrakel) or a spike roller. The use of a spike roller ensures optimum de-aeration to prevent air pockets in the cured levelling compound.
4. On larger surfaces, it is recommended to apply the levelling compound with the appropriate machine technology, using the pumping method.
