The Comparison of Water, Water Vapour Transport Properties and Mechanical Characterization of Two Commercial Plasters on Market in the Czech Republic

摘要

This article deals with the comparison of two different renovation plasters produced by different companies in the Czech Republic. The selected stuccos were Feinputz 212 supplied by HASIT Sumavske vapenice a omitkarny s.r.o and Kbelosan F from Knauf Praha spol. s.r.o. They were studied in the means of basic physical properties, mechanical properties, water transport properties and water vapour transport properties. Results revealed only slight variations in bulk density, matrix density and open porosity, but in the means of transport properties, the plaster Feinputz 212 showed much higher openness to water and water vapour transport.
