Utilização de argamassa industrializada de reboco para fachada

Abstract

The use of pre-mixed plaster mortar for facade rendering has become an efficient and practical solution. This type of mortar is manufactured in an industrial setting, which ensures the standardization of its composition, unlike traditional site-mixed mortars that may present variations affecting performance. Its application reduces execution time and material waste. Another relevant benefit is sustainability, as controlled production decreases environmental impact. Thus, its adoption meets quality and productivity demands. This article aims to analyze the use of pre-mixed plaster mortar for facade rendering in company X’s constructions, highlighting its advantages and disadvantages concerning compressive strength, water absorption, and adhesion compared to conventional mortars. The methodology involved a literature review on the advantages of pre-mixed plaster mortar over traditional mortars, considering the performance of laboratory tests for compressive strength, adhesion, and water absorption, in accordance with standards (NBR 6136-2006, NBR 13281-2023, NBR 13528:2019). The results indicate that the pre-mixed plaster mortar for company X’s facade provides good compressive strength, averaging 2.2 MPa, good water absorption resistance, showing an average of only 2.18% absorption, reduces material waste, optimizes execution time, and improves the final finish. It is concluded that the use of this material is an efficient and sustainable alternative for facade rendering, contributing to improved productivity in the construction sector.
