"Plastering with MP-75 Diamant gypsum mix"

Dry gypsum mix has increased hardness of the surface and compression strength. Plastering works are carried out using PFT-G5 German equipment.

"MP-75 Diamant" is designed aiming for high quality of works and considering future needs.

Advantages of the "Knauf MP-75" Diamant mix:

1. Good water vapor diffusion;
2. Very good bending strength;
3. Rigid structure;
4. High compression resistance.

Note: The Knauf MP-75 Diamant mix is used for works in public premises, stairwells and schools.

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 Diamant gypsum plaster has excellent thermal conductivity properties (0.47 W/mK). Thus, the smaller the coefficient λ, the smaller the heat loss.
