¿Cómo nivelar un suelo correctamente?

How to correctly level a floor

Leveling pastes are used to repair, regularize and improve the original substrates.

They also offer various advantages, in that they:

  • Increase the superficial hardness of the substrates.
  • They cover, regularize and stabilize existing level differences.
  • Substrates compatible with the new cladding are achieved, whether ceramic, wood, lightweight flooring, micro-cement, etc.

Preliminary analysis

In order to correctly level a floor, the use of a mortar with special characteristics is required, such as:

  • High mechanical resistance.
  • Fast setting.
  • Fine-textured finish.
  • High self-leveling capacity.


GECOL Nivelante range amply fulfills the previously described requirements.

Technical considerations

Prior to the application of a product of GECOL Nivelante range, it is essential to analyze the substrate to be treated, it is necessary to have solid, clean, stable, rough and perfectly set supports.

To this end, we will take the following into account:


  • Absorbent or very absorbent substrates:


A substrate is considered to be highly absorbent when a drop of water is absorbed by it in less than a minute.

In the case of absorbent substrates, a coat of GECOL Primer-TP diluted with water in the ratio 1:3 is applied on a dry base.

In the case of highly absorbent substrates, a second coat diluted with water in the ratio of 1:3 is applied once the first coat is dry to the touch.

Let the coat dry between 3 and 24 hours before applying GECOL Nivelante.


  • On non-porous substrates:


Directly apply a coat of GECOL Primer-TP without diluting on a dry base.

Let the coat dry between 3 and 8 hours (depending on the weather conditions at the time) before applying GECOL Nivelante

Respect expansion or fractionation joints every 25 m2, as well as perimeter and structural joints.

In all cases, they must be filled with elastic G#color Elastic-MS.

In pavements with radiant heating, it is recommended that it be disconnected 24 hours before.

For a correct termination it is recommended to use a barbed roller to eliminate the occluded air inside the product.
