Levelling the floor


Self-levelling groundwork for all interiors

Flooring groundwork is one of the most significant elements of buildings. The strength and load capacity of finishing layers that are
floors depend on it. This is why their proper selection considering the strength and used finishing materials is so important.

Parquets, tiles or panels require a properly levelled groundwork. The best choice, considering the above, are the self-levelling groundworks. They should be applied with a limited thickness of a few or below twenty millimetres, the most suitable for that would be RENOGRUNT 410  . This groundwork should be applied with a thickness of 2 to 20mm. It is possible to stand on it only 5 hours after spreading under suitable conditions.

In case of the necessity of spreading a greater thickness, it is best to use RENOGRUNT 411, (used within the range of 5 to 35mm). If the setting is essential, we recommend RENOGRUNT 412, a grout that we can walk on only after 2 hours, and start tiling after 24 hours. The setting time is crucial while performing works in communication strings, where one needs the room to be available within a short period of time. Grouts 411 and 412 contain reinforcing fibres positively influencing the mechanical strength (e.g. compression strength of 30MPa).

All the grouts from the RENOGRUNT line are materials based on cement, due to which, apart from high strength, we also receive water resistance. It has a great importance in bathrooms, kitchens and other places where moisture occurs.

While levelling beds with self-levelling grouts, it is very important to follow the technological conditions:

  • maintaining proper application temperatures (from +5 to +25̊C),
  • adding water per instructions on the packing,
  • adequate surface preparation (cleaning, priming with a properly selected product).

It is worth mentioning that the surface needs to have a proper load capacity, its low strength often results in separation of the self-levelling grout. The detailed product use can be found on the packing and in the product data sheet.
