RT Bond Nt Stone adhesive is a high quality adhesive used for the permanent fixing of tiles over smooth surfaces such as existing tiles, ceramic tiles or glass, subjected to damp and tropical conditions and for specialized applications such as tile on tile and tile-on-glass etc.
RT Bond NT is a two components, polymer modified cement based grey/white
colored powder.
Density of the mixed material: 1.90g/cc
Pot life: Approx. 2 hrs
Setting Time:Initial – 11 hrs Final – 2 days
Pull out bond strength on tile at 28 days: > 1.3 N/mm²
Compressive strength (N/mm²):3 days:- 9.8, 7 days:- 15.70, 28 days:- 20.9
All surfaces must be sound and thoroughly clean before RT Bond VT is applied. All traces of grease or oil must be removed with suitable degreaser. All loose particles of mortar, old wallpaper, paint etc., must be physically removed. In case of cementations surfaces, the areas of application must be thoroughly wetted with water to obtain saturated surface dry condition. In case of smooth surfaces, pre wetting of substrate with water is not essential.
RT Bond NT should be mixed with water in the ratio of 3: 1 by volume or 4:1 by weight. While mixing, add powder And Liquid to the water to avoid lump formation. A slow speed drill fitted with a suitable mixing paddle is recommended for mixing. Hand Mixing may also be resorted to if small quantities are mixed. (Note: Use of chilled water in extreme temperatures will increase open time of RT Bond NT)
RT Bond NT is spread on the substrate to a uniform thickness of 4 to 5mm. This is then combed horizontally with a notched trowel. The tiles are then placed firmly into the adhesive bed ensuring good contact with the mortar by a twisting motion.
RT Bond NT is supplied in 20 kg bag. 6 months in unopened bags under normal warehouse conditions. Bluetile Type-3 must be stored in a cool dry place.
