• Clean the surface of the tiles of all the loose particles, dust etc. and moisten with water.
• Apply Hack-Aid-Plast to the underside of the tiles and receiving surface and wait for 10 minutes by which time the surface will become tacky.
• Place neat cement slurry or cement mortar as required on the primed tile surface and spread it uniformly. Remove the excess by a notched trowel.
• Press the tile home into position.
• Fill the joints not before 48 hours of fixing the tiles.

Note: The primed tile and the surface must be bonded within 60 minutes of application of Hack-Aid-Plast.

3. How can large sized stone slabs be fixed on external facades?

Large-sized stone slab can be fixed on external façade by mixing of Polyalk TF in

(i) Slurry or bonding mix &
(ii) Fixing and bedding mortar

Polyalk TF slurry is prepared using 1 part by weight of Polyalk TF and 1 part by weight of cement. Both the ingredients are mixed thoroughly in a mechanical mixer. Mixing has to be carried out until the mix is of uniform consistency.

Polyalk TF mortar is prepared using :

1 part by weight Polyalk TF,
3 parts by weight of ordinary Portland Cement,
9 parts by weight of Graded Quartz sand.

The three ingredients taken in the above proportion are mixed together to form a mass of thick pliable dough like consistency. Add as little water as possible.

Method of use

• Clean the receiving surface of all the loose particles, oil, grease etc.
• Wet the surface
• Prime the back of the tile and receiving surface with 1:1 slurry of Polyalk TF and cement.
• Spread the Polyalk TF Mortar mix uniformly on the back of the already primed tile. Remove excess material by a notched trowel and press home the tile into position. A 3 mm thick layer is more than adequate.
