ARGAMASSA AUTONIVELANTE

The surface that will receive the ARGAMASSA AUTONIVELANTE must be firm and in good condition, clean, dry and free from dust, oil, grease, paint or any other residue that could impair the product’s adhesion. Concrete surfaces with excess release agent must be brushed well and washed to promote adhesion of the material. The surface that will receive the ARGAMASSA AUTONIVELANTE must be firm, with no hollow sound. If you present this pathology, you must undergo prior treatment. Cracks and fissures must be treated and stabilized, as they may reappear on the surface of the ARGAMASSA AUTONIVELANTE. On painted surfaces, it is necessary to scrape and wash to remove all the paint on the surface. If there are problems with rising damp or the possibility of future damp, it must first be waterproofed with SELAMIX. Larger imperfections and wear on the floor cannot be greater than 5 mm in depth. If present, they must be previously corrected with MASSA DE ASSENTAMENTO MCMV, facilitating the leveling of the ARGAMASSA AUTONIVELANTE.

Subfloors must be washed with a high pressure washer to remove loose particles and must be cured for at least 14 days. New concrete surfaces must be cured for a minimum of 28 days. In thicknesses from 4 mm, at the points of contact between the ARGAMASSA AUTONIVELANTE and baseboards, walls, equipment bases, ends, it is necessary to place strips of polyethylene blanket or sealing tape, to form a joint and prevent the appearance of cracks . It is also important to respect the existing expansion joints and create fractionation joints every 25 m².

We recommend applying the ARGAMASSA AUTONIVELANTE at an ambient temperature between 5ºC and 35ºC and a surface temperature between 5ºC and 27ºC. It is important to insulate untreated metal parts, as they may stain when in contact with the product. Before starting to apply the ARGAMASSA AUTONIVELANTE, the surface must be thoroughly wetted, avoiding puddles.
