Internal wall cladding : Our Knowledge Publishing : 9786206317241 : 6206317242 : 07 Aug 2023 : The application of internal coating with plaster paste is an executive method widely used outside the country. With the constant technological variation and the need to reduce steps and execution time of activities, this coating has been gaining more and more space in the national scenario. Thus, this work aims to evaluate the use of this type of coating, analyzing its physical properties (tensile adhesion strength) when the thicknesses of the applied layers vary by 1.5, 2.0 and 2.5 cm. The results showed that the coating, especially in the thickness of 1.5 cm, did not meet the minimum resistance established by NBR 13749. Material and labor aspects were also surveyed in real situations of use through the application of questionnaires in eight companies. It was found that the use of internal coating with gypsum paste still needs greater adaptation by traders and a greater supply of qualified l
