BS 5980:1980, Draft CEN:prEN 12004 -1997
DESCRIPTION
Because of the closed grained nature of granites ordinary adhesives are not enough for permanent fixing of granite to the cementitious surfaces. The deficiencies in the ordinary adhesives are seen from the weeping granite joints which stain the grainite and make them look ugly and eventually the grainites start coming off. Perma Grainite Tile Adhesive (GTA) is a specially developed product keeping in mind the closed grained nature of the grainites and the long aesthetic life of the surface. GTA is a two component product comprising of pre weighed and packed liquid and powder components in the proportion of 8 kg of powder and 2 litres of liquid.
PRIMARY USES
Perma GTA is mainly used for fixing granite tiles and slabs onto horizontal as well as vertical cementitious surfaces.
DIRECTIONS FOR USE
Ensure that the surface to be tiled is clean and free from dust, grease etc. Wash the rear surface of the granite with water and allow it to dry. Mix some quantity of liquid component of the GTA with water in the proportion of 1 : 1 and brush this liquid on the rear surface of the granite. Pls note that 10% extra liquid is packed to help in priming. Mix GTA liquid and powder components thoroughly to get a smooth consistency paste. Apply this paste on the surface to be tiled as well as on the rear surface of the granite and press the grainite in position. Support the granite for 24 hrs on vertical surfaces till the adhesive develops sufficient strength.
