Plastering with Gypsum Plaster Mix MP75 F

Universal gypsum and lime mix. Plastering works are carried out using PFT-G5 equipment from Germany. N.B.: Knauf MP75 F. Special grains in the mix allow creating the rumpled grainy structure.

Advantages

  1. Permeable to water vapours.
  2. More elasticity.
  3. Gypsum and lime mix without additives.
  4. It is possible to create the grainy surface structure.
  5. Plastered walls do not need any additional decorative material.
  6. When a plastered wall dries, it can be painted immediately.
  7. Money saving.
  8. MP75 F gypsum and lime plaster.

Useful tips

In winter, the amount of water vapor in the air indoors is greater than outdoors. Due to the difference in pressure, the warmer water vapor tries to move from the inside to the outside. This is called water vapor diffusion, or, in spoken language, “plaster breathing”. Depending on the plaster mix used, the diffusing water vapor meets certain resistance (μ). The greater the water vapor diffusion resistance factor, the slower the water vapor diffusion through the material.

Thermal conductivity is the capacity of the material to transfer heat, i.e. the thermal insulation of the material. This feature is described by the thermal conductivity coefficient λ (expressed in W/mK). The lower the λ value, the better the insulating properties of the material. It must be noted that MP-75 F gypsum plaster has excellent thermal conductivity properties (0.58 W/mK). Thus, the smaller the coefficient λ, the smaller the heat loss.
