Impact of Hydrophobic Additives on Properties of Clay Plaster

Abstract:

Use of clay plasters in the exterior forces owners to conduct frequent maintenance of the plaster’s surface, which may be damaged by the weather. This paper describes partial results of the research, which strives to develop cost-efficient hydrophobic additives to increase service life of exterior clay plasters. We have chosen 7 hydrophobic materials and added them to the reference prefabricated plaster mixture. Samples of the enhanced plaster were tested to evaluate the additives’ impact on the overall mechanical, thermal and moisture characteristics of the plaster. Long-term testing of the best hydrophobic additives will follow to verify their properties in real buildings. Clay plasters play a significant role for the healthy indoor climate due to the influence on the stability of the indoor temperature and humidity.
