DESCRIPTION
Perma Marble Tile Adhesive is a cementitious material in white powder form, which only needs on site addition of water to make a paste which is used for fixing marble slabs, marble tiles, to cementitious surfaces vertical as well as horizontal and glass mosiac tiles.
PRIMARY USES
Perma MTA is especially developed for fixing marble slabs and tiles. Marble is generally loose grained and has a porous structure. Ordinary adhesives and grey cements have a tendency to leach into the marble surface with time and stain the surface. Because of this reason even the best selected marble shows the signs of becoming dull and grey and yellow very soon. Perma MTA not only helps in scientific fixing the marbles, but also helps in maintaining the same lusture of marble for years and years. Perma MTA makes the tiled area waterproof.
DIRECTIONS FOR USE
Ensure that the surface to be tiled is clean and free from dust, grease etc. Mix MTA with clean water in the proportion of 3.5 volumes of powder to 1 volume of water. Mix till a uniform consistency, smooth white paste is obtained. Leave the paste for 10 mts in the pan for the entrapped air if any, to escape and remix the paste. Apply this paste uniformly on to the surface to be tiled as well as back of the marble and press the marble in position. While using MTA wetting of the marbles or the surface to be tiled or curing is not required. Fill the tile joints with uniwhite Perma C-toner Filler after 24 hrs of tile laying.
