PROJECT 6.1 • • • 6.2

Pre-commencement Requirements Approved drawings and work procedures shall be obtained from O / E prior to the start of activity Safety regulations as per specifications and standard. Ascertain the nature and location of all existing above and underground services on site by visual survey. General Requirements

Before start of the work the following shall be ensured: • • • 6.3 • • 6.4 •

6.5 • • • • •

6.6

Tools, Equipment & Machinery is suitable and approved for use. Availability of suitable quantity of approved material for the works as per specification and O/E requirements. Area clearance obtained from other discipline/subcontractor. Co-ordination with Other Trades No Tiling works to be started on any wall until and unless it is cleared for tiling. Prior to start of tiling works, check all architectural, mechanical and electrical works are completed and MEP clearances shall be taken as required. Scaffolding Scaffolding will be erected using standard and ledgers by well trained scaffolders for doing painting above 1.5m high. Wooden planks should be placed over ledgers to serve as working platform with proper toe board. Delivery, Storage & Handling of Materials All materials shall comply with the specifications regarding quality, dimensions, strength etc. The material shall be approved and shall be used as per the Finishing Schedule. The color of the Ceramic Tile shall match the appropriate approved sample. The Ceramic tile shall be stored under covered area to prevent damage and soiling and kept in cartoons until removed for fixing. Manufacturer’s recommendations shall be followed for storage and handling.

Execution

 Surface Preparation •

All surfaces to received tile shall be structurally sound clean, dry and free from oil and all foreign matters. Page 6 of 11


PROJECT • •

Surfaces to receive tile shall be plumb, horizontal level or at the slope as specified and true with square corners. Prior to placing of tile the concrete surface shall be kept thoroughly wet.

 Mixing •

6.61 • • • • • • • • • • • • • • •

Mixing and applications of Adhesive and grouting shall be complied with manufacture’s procedure and recommendations.

Wall Tile The wall to receive tiles shall be finished with cement/ sand plaster as per approved method statement. The plastering to the wall surfaces must be fully cured and free from any contamination, dust and crack before commencing the wall tile works. Setting out shall be done as per approved shop drawings. The surveyor shall mark the finished floor level on the wall of the room. The wooden plywood strip shall be fixed above 2 tile high from FFL on the wall. Ceramic tile shall be soaked in water and it should be removed 20 minutes before use. Wall tile fixing shall start from the fixed wooden strip level. Approved adhesive materials shall be applied to the wall as continuous even float coat and the wall tiles are fixed to the adhesive with twisting/sliding action to give the finished bed thickness not more than 3mm. Tile shall be correctly positioned in both directions by using 2-3mm plastic spacers to achieve even joints. To check the adhesion as the work proceeds, a sample tile shall be removed immediately after fixing as per O/E instructions and refixed without any delay. The tile shall be fixed in away to get solid bedding and adhesion over the whole of the tile background. Excessive adhesive material shall be removed with damp cloth without disturbing tiles. The cut tiles and the tiles on the sides of sanitary fittings and fixings shall be properly cut and laid in a neat manner. After fixing wall tiles floor tile shall be started as mentioned in section 6.62 The fixed tile shall be left for minimum of 24 hrs to cure before grouting. Page 7 of 11


PROJECT • • • •

NO ACCESS or Warning tapes to be fixed upon completing tile fixing and no other activities shall be allowed until the tiles are firmly set. Before start grouting, all spacers should be removed and ensure that there is no damages. Simultaneously the tile shall be cleaned with the dry cloth to give a aesthetic look. The grouting mixing and application shall be followed as per manufacturer’s data sheet/recommendations.

6.62 Floor Tile Installation • • • • • • • • • • • • • •

In interior finishing works, all tiles shall only be set and laid after the fixing of window and door frames and trims, stop rails, electrical, plumbing installations as well as the application of plaster unless otherwise specified. All anchors, recessed frames, electrical and mechanical items shall be installed tested and approved prior to commence with floor tilling. For wet area only the approved water proofing system shall be installed. Carry out a 24 hrs water test for water tight purpose prior to start with tile activity for wet area only. The surveyor shall mark the required level of the bedding screed /protection screed to the specified thickness and in true alignment and horizontally or to slope as specified as per the approved drawings. Install polythene sheet and a protection screed of 50-60mm thickness with slope 1% towards the floor drain shall be applied and it should be cleaned. Setting out shall be done as per approved layout drawings. Joints shall be true to line, truly horizontal, continuous and without steps. For wet and dry area, ceramic tile shall be fixed by approved Tile adhesive. Ceramic tile shall be soaked in water and it should be removed 20 minutes before use. Adhesive shall be applied on working area not more than one square meter at a time or as per manufacturer’s recommendations/procedure. Tile shall then be laid on the adhesive layer with a twisting motion ensuring good contact between tile and adhesive bed. For this purpose the adhesive manufacturer’s instructions should be followed strictly to achieve the 100% mortar coverage. Tile shall be correctly positioned in both direction by using 2-3mm plastic spacers in order to accommodate the difference between wall and floor tiles as per approved drawings. The tile shall be neatly cut to a close fit where the necessary at abutments, around the outlets, pipes and the like. Particular care will be taken in ‘Wet’ areas to prevent low spots that may promote water pooling the tolerance in the overall level shall not be more than5mm from required level. Page 8 of 11


PROJECT • • • • • • •

Localized variation in level for nominally flat floor shall be max of + or – 3mm, when tested by 3meters straight edge. Excessive adhesive shall be removed with damp cloth before the material has set. The fixed tile shall be left for minimum of 24 hrs to cure before grouting. NO ACCESS or Warning tapes to be fixed upon completing tile fixing and no other activities shall be allowed until the tiles are firmly set. Before start grouting, all spacers should be removed and ensure that there is no damages. Simultaneously the tile shall be cleaned with the dry cloth to give a aesthetic look.
