    New trends in coatings such as Gypsum, Ceiling and Melamine have been used more frequently in buildings today, but it has not been possible to analyze their behavior when faced with an ignition source, their reaction to fire and their contribution in the event of a fire. Based on this, an investigation of the reaction to fire of these materials was carried out with the application of a direct flame to the surface for 30 seconds and they were classified according to the Euro classes that determined the characteristics and behavior of the material in front of a flame; For which 36 samples were tested, 18 plaster samples in 3 different thicknesses and 18 melamine samples in 3 thicknesses, the same are applied in Gypsum, Ceiling, wall covering, among other uses; the samples were extracted 3 in longitudinal direction and 3 transversal for both materials, with the purpose of knowing if the direction of application of the material influences its combustion. As a result, it was found that no sample reaches initial ignition and the flame does not reach 150 mm in height, which is the maximum range established by the NTE INEN ISO 11925-2 standard. Based on this, Gypsum was classified as class C and melamine as class D, highlighting that for smoke production it is s3 and flaming droplets is d2, where these two materials do not declare any behavior.
