    The new coating techniques have been used significantly in constructions, in such a way that their behavior against fire has not been considered, which raises questions regarding fire events. From the above, this investigative work was developed on fire reaction tests of construction materials such as Gypsum/ceiling and melamine subjected to the direct action of the fire flame according to the NTE INEN-ISO 11925 standard. 2, for which the physical properties of each material were analyzed and subsequently tested on edge for 30 seconds. In addition, a total of 36 samples were obtained, taking into account 18 specimens of each material with their 3 respective thicknesses, and 3 sectioned longitudinally and 3 transversely, in order to know if the direction of application of the material influences the its flammability. As a result, it was obtained that the melamine materials present an initial ignition, which does not occur with the Gypsum/ceiling materials. It was also evident that the vertical propagation of the flame does not reach the height of 150mm, consequently according to the behavior against the fire and according to the physical properties, each material was classified according to the EN 13501- 1 standard, where Gypsum/ceiling was categorized in class type C, and melamine in class type D, highlighting that all these materials for the production of smoke It is class type S3 and for the fall of inflamed droplets/particles it is class type D2.
