This research studies aims the determination of bond of rendering mortar, through shear efforts. The ABNT NBR 13528:2010 prescribes the test method of bond
strength of mortar rendering, determined a constant load applied on a normal metallic device, connected directly to a specimen rendering mortar to be tested. This survey
sought to verify, in the laboratory, the determination of resistance to shear adhesion as another parameter in the evaluation of rendering mortar. This study was carried
out by testing pullout oblique to the rendering to be parsed. The same standard recommends that delimitation of the body surface-specimens these should be circular 50 mm in diameter. However, in this work were used specimens of squared form whose sides measure 100 mm having both surfaces in order to adapt the form and type of carrying out the tests to be carried out in the search. For the research achievement were made of ceramic bricks panels which were tested specimens under the angles from 0°, 45° and 90°. To make it possible to carry out the tests
under the angles of 45° and 0° required adapter devices to run their tests. The goal of this work was to determine the resistance to shear adhesion from applying a load
of pullout applied obliquely to finish. Through an analysis of variance, the results suggest a relationship between the workload pullout oblique (45°) and the resistance
to shear adhesion (0°), goal of this research
