Levelling compound — FN 15

Field of application:

For leveling concrete bases and floor screeds on a mineral basis, followed by facing with ceramic coatings, as well as coatings made of linoleum, etc. inside residential and civilian premises. It can be used as a monolithic-jointed floor, a monolithic floor on a split layer, a monolithic "floating" floor, screed leveling with heating elements (heated floor). The recommended layer thickness is from 3 mm to 15 mm.

Features:

grade strength - M200;
resistant to mechanical influences and abrasion;
suitable for machine pouring;
for warm floors and "floating bases".

Advantages:

Water and frost resistant

Self-leveling

Resistant to shrinkage

Hardens quickly

Preparation of the base

When preparing the base, it is necessary to comply with the requirements of DSTU-N B A.3.1-23:2013, DSTU-N B V.2.6-212:2016 and SNiP 2.03.13-88. The base must be load-bearing and strong, cleaned of dust, dirt, lime, oils, fats, wax, paint. To create a clean contact layer, it is necessary to clean the base from dust using a household or industrial vacuum cleaner. Weak layers should be removed, existing cracks should be widened, primed and filled with FN 15 mixture. Surfaces that strongly absorb liquid should be treated with a deep penetration primer and allowed to stand for at least 4 hours. Weakly absorbent surfaces should be treated with an acrylic primer and left for at least 4 hours. It is necessary to separate the monolithic floor from the walls and columns with a thin elastic layer (for example, thin strips of polystyrene foam).
Preparation of the solution

Pour the dry mixture into a container with clean water at room temperature in the proportion: 0.19 l per 1 kg of the mixture (4.75 l per 25 kg bag). Mix with a drill with a nozzle (manual pouring) or a pressure mixer (machine pouring) until a homogeneous state. After that, keep the mixture for 5 minutes and mix thoroughly again. With each new mixing of the mixture, it is necessary to control the mixing time (approximately 6 minutes) and the consistency of the mixture. The mixturecan be used within 30 minutes from the moment of preparation. Use clean containers and tools for cooking.
Recommendations

On areas of more than 20 m², it is necessary to perform deformation joints. If there are deformation seams in the base, they must be duplicated in the next layer. In the presence of a "warm floor" system, if it is turned on, it must be turned off before leveling the surface of the base. During the work, the temperature of the mortar mixture and the base must be the same. When using in underfloor heating systems, follow the rules of work specified by the manufacturer of the heating system. Turn on the heat load gradually, no earlier than 28 days after the installation of the underfloor heating. The arrangement of the following layers should be carried out in accordance with the recommendations of the material manufacturers, taking into account the presence of a "warm floor" system if necessary. Application in rooms with a high level of humidity (bathrooms and shower rooms, etc.) is possible only with the installation of additional waterproofing. In addition to the above information on how to use the material, when working with it, you should be guided by the current regulatory documents on the arrangement of the floor. In the case of using the material in conditions not considered in this technical description, it is necessary to independently conduct tests or seek advice from the manufacturer. The floor mixture FN 15 contains cement, which causes an alkaline reaction at the moment of hydration, so it is necessary to protect the eyes and skin when working. If the solution mixture gets into the eyes, they should be immediately washed with running water and consult a doctor. An excess amount of water causes delamination of the mixture, increases the time it takes for the mixture to harden, and reduces the quality of the coating.

Execution of works

Before carrying out work, it is necessary to determine the future thickness of the layer. The marked technological area is filled with the mixture, starting from the furthest corner. The poured mixture is immediately deaerated (removed air) using a nee
