Plastering process

The exterior walls are the visible part of the house which is affected by various climate conditions. Therefore, the owners are not the only ones concerned about plastering it correctly in order to avoid problems in the future. We will employ Knauf plastering technology to comment on some of the more significant moments of plastering exterior walls.

Prior to starting plastering the exterior part of the house, the walls are sprayed with the Knauf Vorspritzer preparation plaster.

Knauf Vorspritzer is dry mix of cement and sand prepared in the factory. It is used as a primer prior to plastering with KZ Maschinenputz plaster.

After the primer dries, a layer of Knauf KZ- Maschinenputz of the required thickness is sprayed.

An excellent result is achieved by smoothing the surfaces with trapezoids and rubbing them over.

Plastering of exterior walls requires skills and is not a low-cost process. When plastering exterior walls one must remember that the physical outlook is not the only important quality. Quality and durability of plasters used for exterior walls, their resistance to heat and cold, hydrophobic properties, diffusion, etc. play a big role as well.
