ABSTRACT
The monolayer system presents itself as an alternative to the conventional mortar and decorative painting system. In this work, the performance analysis of the mono-layer system was carried out in relation to the tensile bond strength and tightness by the pipe method before and after the submission of standard substrate plates to accelerated aging in a weathering chamber. Prototypes were subjected to aging cycles, equivalent to 6 years and 3 months of natural exposure. It is concluded that the non-weathered substrates are more permeable than the weathered ones. The tensile bond strength of substrates with and without weathering met the parameters established by ABNT NBR 16648 [11 ASSOCIAÇÃO BRASILEIRA DE NORMAS TÉCNICAS, ABNT NBR 16648: Argamassas inorgânicas decorativas para revestimento de edificações – Requisitos e métodos de ensaios, Rio de Janeiro: ABNT, 2018.].
