1.0 Introduction
This method statement gives a step by step procedure for Porcelain Tiling
of Floors and Walls.
2.0 Method of Porcelain Floor & Wall
Tiling.
- Preparation
of the surface of concrete: 1:3 Cement Sand screeds will be done over the
prepared surface to make bedding for tile.
- The surface of the tile bed will be formed as a rough surface.
- The
rendering will be cured for at least 14 days and allowed to dry.
- Before
laying the tile, base tile line (reference line for positioning of tiles)
will be marked on the bedding.
- Before
fixing of tiles, the bedding will be wetted and allowed to dry.
- Adhesives compatible with the materials and surfaces to be adhered
shall be used in accordance with the adhesive manufacture’s
recommendations for the condition of use.
- Tiles will be soaked in water for
about half an hour, then stacked and allowed to drain excess water.
- To
commence the installation of wall tiles, Cement grout will be applied over
the wall tile and place the tile on the wall and level & line will be
adjusted using a rubber mallet.
- Move
the tile slightly in all directions to ensure the bond. Once it is satisfied with the bond, move the tile to its final position. Repeat the process for each tile.
- To
commence the installation of floor tiles, Cement paste will be applied on
the tile bed using grout trowel and place the tile on the floor and same the procedure will be repeated as mentioned above.
- The
width of the tile groove (Approximately 3mm for Floors & 2mm for
Walls) will be maintained uniform over the area.
- The squeezed cement grout collected in the tile groove will be removed & cleaned properly. The tile grooves then will be finished with the approved tile grout and the entire surface will be cleaned with a damped cloth before hardening any excess tile grout over the tile surface.
- Tile
grout will be properly mixed with water as per the manufacturer’s
instructions. The tile grouts will be spread over the surface with a grout float (i.e. Flexible Rubber Pad). During the application of grout, the grout float will be held at a 45-degree angle to the floor or wall,
pushing the grout securely into the gaps. Scrape the flat edge of the grout across the tile surfaces to remove residual grout and the entire surface will be cleaned off with a damped cloth before hardening any excess tile grout over the tile surface.
- During
the fixing of tiles, a straight edge (normally 100mm x 25mm Aluminum hollow bar) will be used to check the evenness of the tile surface and plumb bob will be used to check the verticality. If the unevenness is found,
any corrections will be done within 10 minutes of fixing of tiles.
- Provide
spare matching tiles of each type, in quality not less than 2% of the quantity installed, including accessories in the proposition, for future replacement purposes. Store spare tiles in works where directed.
