Moisture level significantly affects durability of constructions, their thermal performance and quality of indoor air. As the building envelopes are subjected to the effect of changing weather conditions from the exterior and numerous sources of water vapor from interior, the proper design may significantly increase the performance of the construction. In this paper, modified plasters with different amount of super absorbent polymers (SAP) are analyzed in the laboratory conditions in terms of their hygric and mechanical properties. The results showed that addition of SAP in the plasters may be promising for the utilization in building envelopes composition. However, the exact amount of SAP is crucial as the results revealed that if more that 1% of SAP is added to the plasters, the poor mechanical properties may exclude the plasters from real applications.
