How to lay Knauf floors, floor elements

There are two main versions of the device floors: the priming method on the basis of screed from mortar (cement-sand) and bulk using prefabricated structures. The second method is used less often, but it differs in the economy of production. Consider the method of installing a bulk floor using the products of the leader in this market - the German firm Knauf.

Products of the company "Knauf"

This German company is widely known on the market and for many years is distinguished by the excellent quality of its building materials. The list of its products includes sheets of gypsum plasterboard and hypo-fibrous, slabs pazogrebnevye, mixtures of liquid building. Particularly widespread in our country have received bulk floors Knauf.

Knauf floors, flooring elements

The products of this segment include "Knauf" -superlist (usual and moisture-proof) and floor elements "Knauf". Gypsum fiber "Knauf" -superlist is a high-quality, environmentally friendly and fireproof material. It has good sound and heat insulation properties. The dimensions of the sheet are 250x120 with a thickness of 1 or 1.25 cm. It is used as a compensating layer with a backfilling thickness of less than 15 cm if Knauf floors are used.

Elements of the floor are made of moisture-resistant "Knauf" -superlistov. At the same time, two sheets with dimensions of 120x60x1 cm are glued together. As a result, the floor element is 1200x600x20mm "Knauf" - a sheet with folds along the entire perimeter 5 cm wide.
The floor construction "Knauf" consists of a layer of film, a layer of expanded clay and the actual elements of the floor. Implementation of works on the device of a floor differs following advantages:

• short terms;
• elimination of "dirty" work;
• The resulting perfectly flat floor base with convenient placement of all communications.

For laying the floor "Knauf" is suitable not only a flat surface, but also an uneven base with defects covered by a layer of embankment.

Advantages of Knauf floors

• Ideal evenness of the floor.
• Hypoallergenicity of materials.
• Absence of creaks and faults during the whole period of its operation.
• Ready to use the floor immediately after installation.
• Excellent sound insulation (in comparison with cement screed or bulk floors);
• Inability to flood neighbors, because water does not work during operation.
• Low thermal conductivity of Knauf floors.
• High speed of work execution.
• Possibility of alternate arrangement of floors in different rooms on one level.
• Possibility of any floor covering (for example, parquet).
• Ability to install electrical warm floors (water warm floors can not be arranged).

The device of a floor the hands

There is no problem in self-equipping the floors of Knauf. Elements of the floor, the necessary materials and tools must be purchased and gradually execute simple instructions:

• prepare the surface;
• proolozhit vapor and moisture barrier layer and soundproofing layer;
• Covered with expanded clay;
• lay the floor elements "Knauf", their installation is fairly simple, enough to fix the screws and glue;
• finish the floor.

Laying of floor elements "Knauf"

When preparing the surface, if repairs are to be carried out, remove the old coating, dust and construction debris, cover with alabaster or gypsum mortar all cracks and holes in the base. In the presence of wires, they must be placed in the corrugation and pressed to the floor (the layer of expanded clay above the corrugation should exceed 2 cm).

When installing the vapor and moisture barrier layer with the help of a level, it is necessary to mark the top level of the claydite filling (from two to six centimeters depending on the unevenness of the base) along the walls, plus 2 cm for the thickness of the floor elements. On the base of the floor, overlapping above the level set, the film is laid (with an overlap of more than 20 cm) and fastened with a construction tape. For a concrete base, it is better to use a vapor barrier material (a polyethylene film can be 200 μm), wood bitumen paper or parchment can be used for wood.

When soundproofing is arranged around the perimeter of the whole room along the walls, a sound-insulating material with a thickness of 1 and a width of 10 cm is fixed, self-adhesive or simple, fixed with ordinary tape.

When backfilling with expanded clay, the main thing is to align the surface of the layer with the rule and avoid the formation of voids. For this purpose, the profiles are pre-arranged in parallel with each other in steps of not more than 150 cm at the height noted above on the marks on the walls. The required height is obtained by placing planks or remnants of slabs under them. For the stability of the profiles, their support points should be located at least 70 cm. If a layer of expanded clay is obtained more than 6 cm, then an additional layer of plates must be laid. After the layer is leveled, the profile is removed with the support, and the remaining voids are filled with expanded clay, leveled, and the entire layer is rammed. Moving along the laid layer should be put under the feet squares of sheets of plywood.

At a level surface of the base, instead of filling with expanded clay, extruded polystyrene sheets or other heat-insulating materials are used with the edgeband along the walls.

We finish the arrangement of Knauf floors. It is better to install floor elements from the door. When laying the first row, the folds of the sheets adjacent to the walls are cut off. The subsequent rows are stacked with a displacement of the joints. In this case, the glue is glued with PVA glue and fixed with self-tapping screws 15 cm apart.
