Make sure the consultant or any other responsible authority will accept the type and color of ceramic tiles, the mortar mix, the adhesive, the grout, the shop drawings, and the method of application before you start the tiling process.
Then, confirm that the material is from approved manufacturers and is still in its original packaging. This will guarantee that no fake or unapproved materials are used on the project site.
The approval of mockups prior to major installation work is crucial; this is standard procedure for efficient site construction activities. The mockup must be displayed for consultant or contractor approval and inspection, as necessary.
The materials delivered to the site must be checked with respect to the approved material. Approved mock up and material must be accessible at the site.
Prerequisite for Wall Tiling Work
Prior to starting the tiling job, make sure the MEP clearance was received and that any other under-laying installations were approved.
Unauthorized ingress must be prohibited in the working area.
Before beginning the installation process, the surface to which the tiles will be fixed must be completely dry and defect-free.
All traces of grease, oil, loose particles, etc. must be removed from the areas that will be tiled, and the area must be brushed clean.
Make sure that the direction and pattern chosen with the consultant will be followed when laying the tiles.
Before laying tiles, acquire consultant approval. To reduce tile cutting, adjust the space or areas such that they are symmetrical about their center lines.
Tile work should be laid out with a minimum of cutting so that tiles that are less than half their full size do not occur. Grind the tile’s cut edges with care. Make sure all of the wall faces have equal numbers of cut tiles in the corners.
The layout of the tiles on the floors and walls must match the shop drawings that have been approved.
Method Statement for Tiling at Walls
Apply a leveling coat of plaster that is at least 12 mm thick to concrete block walls and concrete walls that will be finished with tile in order to cover the unevenness of the substrate and ensure that the walls are truly vertical.
In order to have a strong key for tiling works, plaster must be completed rough.
Before beginning tiling work, the plaster curing period must be completed.
A level line must be established to place the starting course in order to guarantee that rows of tiles are indeed horizontal.
Using an approved adhesive, tiles of the specified and approved sizes must be fixed to wall surfaces.
In accordance with the manufacturer’s recommendations, adhesive mixing must be done carefully.
Mortar must be used within two hours of mixing at normal temperatures, or by the end of the mix’s pot life, whichever comes first.
After the initial set has taken place, no material may be employed.
Thin Bed Adhesive-Walls
Coat dry backgrounds with a floating coat of adhesive in areas measuring around 1 M2 and comb the surface with the suggested solid bed trowel.
On the back of dry tiles, spread an even, thin coat of adhesive.
For a finished bed thickness of no more than 3 mm, twist and slide tiles onto the bedding.
Thick Bed Adhesive-Walls
Use the recommended solid bed trowel to comb the surface after applying a floating coat of adhesive to a dry background.
Apply a thin, even coat of adhesive over the entire back of each tile, filling in any gaps, and then finish it off with a sealant. To get a finished bed thickness that is within the manufacturer’s specified range, press tiles onto the bedding using a twisting/sliding motion.
To achieve the required adherence and level, tamp the tile with a rubber mallet.
In order to align the horizontal and vertical joints, spacers must be utilized as well as the required tile spacing.
In accordance with the shop drawings, arrange the tiles according to the pattern. Make sure the pattern continues through any openings.
Where appropriate, draw borderlines.
Before the material sets, excess mix or adhesive must be removed using a damp cloth.
By using consistently applied pressure, the vertical joints must be kept level and plane across the full true level.
After edges of tiles have been fully moistened (after 48 hours), joints in glazed wall tiles and fittings must be grouted with tidy, white or colored approved grout.
Using a sponge or a little piece of soft cloth, grout must be applied to the crevices between the tiles.
Make sure joints are 6 mm deep (or the tile’s depth, if less), and that they are clean and free of debris.
Force grout and fill joints entirely to their full depth, tool to a profile that has been approved, clear off the surface, and leave free of flaws.
When joints in wall tiling are stiff, rub them with a dry cloth.
Keep mortar or grout free of expansion and contraction joints.
Control Joints
Prrovide control joints must be 6 mm wide at a minimum and extend a maximum of 4.5 meters in each direction from the perimeter walls and large tile areas. After placing tiles, avoid sawing joints.
In accordance with the manufacturer’s guidelines, movement joints must be located as required, carried through the backing to the structural wall, partially filled with strip, and finished flush with sealant.
Up until the jointing has fully set, tiling must be shielded from heat and bad weather.
Floor Tiling Work Method
The consultant must have approved the type and color of ceramic tiles, mortar mixture, glue, grout, shop drawings, and application method.
Make sure that the materials are from approved manufacturers and are packaged with their original labels.
For final approval, a mock-up arrangement for wall and floor tiles must be made at the consultant’s selected location.
The materials delivered to the site must be checked with respect to the approved material.
Approved mock up and material must be accessible at the site.
For laying, tiles of approved sizes must be utilized.
Verify the MEP clearance received.
Limit access to the workspace to avoid unauthorized access.
The substrate to be tiled areas must be brushed clean, and the finished floor must be established using dots.
It is necessary to remove any traces of grease, oil, and loose objects, etc.
Verify that approved waterproofing is completed in wet areas in accordance with the manufacturer’s instructions and is tested for leaks
Make sure that the direction and pattern chosen with the consultant will be followed when laying the tiles.
The surveyor is responsible for setting out, and the consultant has approved it.
Before laying tiles, acquire consultant approval. To reduce tile cutting, adjust the space or areas such that they are symmetrical about their center lines.
The start point for tiling should be fixed on the approved shop drawings.
Tile work should be laid out with a minimum of cutting so that tiles that are less than half their full size do not occur. Grind the tile’s cut edges with care. Make sure all of the wall faces have equal numbers of cut tiles in the corners.
Floor Preparation
Cast-in-place concrete substrates must be sufficiently smooth and level so that when thin-set mortar to receive tiles is applied, no voids occur under the tiles.
To prevent gaps from occurring, shave off high spots and fill up low spots as needed.
Toilets and pantries will all have their floors water-proofed.
Apply the liquid waterproofing at a minimum rate of 1.5 kg/m2 on horizontal surfaces, and extend it at least 100mm high on vertical surfaces, or as specified in the method statement and approved shop drawings.
Before installation of porcelain tiles, place a 1000 gauge polythene sheet protected by 10mm mortar layer and coordinate floor water proofing works with the porcelain tiles installer. Both before and after the installation of the tiles, testing is required.
Method Statement for Floor Tiling
The required thickness of tile adhesive should be applied to the wall.
Tiles must be set in place using a rubber mallet and at the level indicated in the drawing.
After installation, remove and replace any solid bearing tiles that produce a hollow sound when tapped with a steel rod.
Tiles shall be laid level or enough falls in wet areas as may be required.
In damp areas, more caution must be exercised to avoid low spots and water pooling.
The tiles must be precisely cut, with exposed edges surrounding pipes and other obstructions being ground rough.
Make floor drains available in accordance with approved shop drawings.
Between sanitary fixtures and tiles, silicon rubber sealant must be put.
When the installation has sufficiently hardened (after 48 hours), a thick grout of cement mixed with the minimum amount of water/approved grout shall be prepared and brushed over the floor until all the joints are completely filled.
Utilizing a dry cloth, excess material must be removed.
Control Joints
Construct control joints for large tile areas at a maximum of 4.5m in each direction and at the boundary walls must have a minimum width of 6mm. After placing tiles, avoid sawing joints.
In accordance with the manufacturer’s guidelines, movement joints must be located as required, carried through the backing to the structural wall, partially filled with strip, and finished flush with sealant.
The joint width must match the approved shop drawings or be 2 mm.Joints must be continuous, step-free, and true to the line.
The completed tile floor should be kept traffic avoided in the area for at least 24 hours. If traffic cannot be avoided, board walkways must be used to prevent damage to floors and maintain a clean environment.
The floors and stairs should receive two coats of sealant finish. Observe the manufacturer’s specified application instructions for the sealer finish.
