4)    Wall tile thiyyas shall be taken before fixing of plumbing pipe outlets and wall tiling layout shall be clearly marked on the plastered surface with clear cut marking of starting point.

5)    Nominal mix proportions for mortar tile fixing shall be decided by Quality Department.

6)    Tiles (Ceramic and Glazed) shall be soaked by completely immersing tiles in water for about 3 Hrs. and then drained for a minimum period of 30 minutes prior to their fixing.

7)     If tiles are to be fixed up to ceiling level, ceiling level shall be checked for perfect horizontal level and necessary rectification shall be carried out to achieve the same, if required.

8)    The wall on which maximum plumbing work is done shall be chosen first for fixing of wall tiles.

9)    Plastered wall surface shall be wetted thoroughly 12 hours prior to time chosen for fixing wall tiles.

b) During Tiling Procedures (Wall tiling / Dado)

1)     It shall be ensured that quality of tiles checked from QA Department. Also proper sorting of tiles shall be done to have uniformity in color and shade. Starting point for each wall shall be followed strictly as per drawing.

2)    Ensure mix proportions from QA Department to form mortar of suitable consistency.

3)    Use of Liquid Tile Adhesive is recommended while making mortar.

4)    Mortar, thus prepared, shall be used before initial setting time of cement or cement fly ash mix.

5)    Use of neat cement paste for fixing tiles shall be avoided.

Circular holes of required size shall be made on tiles at appropriate positions as determined from markings on wall. Holes shall be made from back of tiles with the help of cutter machine.

7)    Mortar shall be applied to back of each tile (8-10 mm thk coat of mortar) before fixing in position and then tamped with rubber mallet to remove hollowness behind. Thickness of compacted mortar bed shall not exceed 8mm.

8)    For dado works in toilets, walls shall be marked with tile fixing layout with correct sizes of tiles to be fixed. Tiles shall be fixed from bottom second layer (full tile) to top leaving bottom most layer of tile. Each tile shall be fixed in plumb with tile thiyya piece using plumb bob. Also line dori shall be stretched between two corner tile thiyya pieces and all tiles shall be fixed in plumb with line dori. Bottom most layer shall be laid after fixing floor tiles. Bottom most tiles shall be cut to correct slope of floor laid, before fixing. Care shall be taken so that top edge of bottom most tiles thus fixed is perfectly horizontal. It should be ensured that bottom support should be removed 2 hrs after completion of wall tiling work.

9)     Fixing of wall tiles in other areas including passage (where no slope is given to floor) shall be done after floor tiles are laid and sequence shall be from bottom to top.

10)      Cement slurry shall be poured within the gap between tiles and plaster after every two courses of tile laying. This is to ensure that there are no voids left behind the tiles fixed.

11)     Cleaning of the tile surface should be done immediately after completion of laying of tiles.

12)     For other precautions to be taken, refer section of floor tiles. For kitchen flooring, slope should be provided towards Nahani trap and waterproofing should be completed to sunk portion of nahani trap and after completion of curing period flooring should be laid. The other procedure of kitchen flooring is same as regular flooring.
