Installation of flagstones

Flagstone is a natural rock stone with a special split structure. It is widely used in construction for external and internal cladding, it is used to lay stoves and fireplaces, and it is used to decorate walls and ceilings. The stone is used for paths, in landscape design, and is used for finishing work in the construction of swimming pools and ponds, playgrounds and flower beds, and alpine slides. The advantages of finishing with flagstone are resistance to frost, moisture, and wear resistance. This environmentally friendly material always looks natural and stylish, and is available in different shapes, colors, and textures. Paving facades with flagstone requires a special technology, where great importance is attached to preparation.

How to prepare for laying flagstone

Preparation of the foundation consists of thoroughly cleaning the walls. Dirt and dust are removed from the surface, and any remains of old plaster and putty are removed. Cleaning should occur right down to the base of the masonry. If there are any irregularities, they are corrected by throwing on concrete mortar or knocking down protrusions. If the surface for facing the foundation is made of concrete, then it is certainly covered with concrete contact - otherwise the stone coating will not last long.

Attention is also focused on the wall material. If it is built of red brick, then the installation of a facade metal mesh is not required. If there is aerated concrete, foam block, gas silicate surface, the stone is installed only on the mesh. It is fixed using dowels at the rate of 10-25 fasteners per 1 sq.m.

Durable paving with natural stone can only be achieved if the temperature regime is observed during the work. It should be in the range from +5 to +30 degrees. When finishing outdoors in the cold season, the adhesive solution will freeze, as a result of which the flagstone will simply fall off the wall later. In the hot period, the heated surface does not contribute to the optimal hardening of the mixture when laying the flagstone, which leads to poor adhesion to the material.

Installation of flagstone: cladding options

Stone facades involve two main methods of work. The choice depends on the type of base material used, which is supplied in the form of stone itself and facade panels under the flagstone. Thus, decorative installation using the wet method of fastening and as part of a ventilated facade are distinguished.

"Wet" installation on concrete involves the following algorithm of actions:

  • fixing the insulating material to the wall using wooden beams or galvanized steel profiles - mineral wool is most often used;
  • treatment of the insulating layer with plaster for outdoor work - the process is carried out with beacons to control the alignment;
  • stuffing a protective mesh on wet plaster if necessary for laying stone;
  • priming in two steps using a special universal composition;
  • installation of natural stone on glue or mortar.

The material is installed in various ways. This can be seam-to-seam, shifting the seams, creating all sorts of ornaments.

The technology of laying the material on a ventilated curtain wall is as follows:

  • selection of material, preparation of tools, drawing up a bracket mounting diagram, selection of fasteners;
  • fixation of the frame and fastening elements;
  • installation of vapor barrier and insulation layers, installation of geotextiles.

Next, facing with flagstone in the form of panels is carried out.

Order cladding work from specialists

Among the many ways to arrange a facade, this option is considered the most original and environmentally friendly. In most cases, it is difficult for an inexperienced craftsman to cope with such a task without the participation of professionals.
