GENERAL SPECIFICATION FOR FIXING PORCELAIN TILES, DARK-COLOURED GRANITE TILES OR DARK-COLOURED MARBLE TILES ONTO INTERIOR RENDERED WALLS, AND ONTO INTERIOR SURFACE BEDS AND SUSPENDED SLABS

 

Please note that ‘general’ specifications are issued for information purposes, and should not be used as project specifications.

As each and every project needs to be assessed individually on its own merits and characteristics please contact the TAL Technical Advice Centre for a project-specific detailed materials and methods specification for specific projects.

 

It is important that the tile selected is suitable for the application, preferably against a written Supplier’s specification. Factors such as water absorption, irreversible moisture expansion, MOR and PEI ratings, chemical resistance and overall stability of the product need to meet the requirements of the service conditions.

The backs of all tiles must be clean and free from dust and contaminants.

 

Please note that any “wet” areas, such as showers or balconies, should be waterproofed using TAL SUPERFLEX  or  TAL SUREPROOF waterproofing compounds prior to commencing tiling. Please feel free to contact us for a specification for waterproofing and tiling these areas, as well as for technical literature on any of our products.

 

TAL PRODUCT REQUIREMENTS

The TAL products required for this installation are as follows:
TAL KEYCOAT  *
TAL GOLDSTAR 6
TAL BOND / TAL BOND POWDER
TAL WALL & FLOOR GROUT

NOTCHED FLOOR TROWEL
SPACERS
TAL SEALMASTER CORD
TAL GOLD STAR SEALMASTER 1000

 

Special note must be taken of the following:
Adhesive System :
We have specified the use of TAL GOLDSTAR 6  rapid setting high strength adhesive for the installation of these tiles. However, if timing on this project allows for a quick setting adhesive option, then TAL GOLDSTAR 12 can be considered.

The advantages of using TAL GOLDSTAR 12 are as follows :

It is however important that newly installed tiles are protected from traffic (other trades, etc) for a minimum of 12 hours, while the adhesive sets. This is especially important in high traffic areas and fast-track installations.

 

Surface Beds:
All surface beds should have a damp proof membrane (DPM / DPC). Should there be no damp proof membrane below a surface bed or if prevailing moisture levels do not attain 5% (75% RH) or less, it is recommended that TAL X-CALIBUR X-SHIELD VAPORSTOP HB (vapour barrier) be applied prior to tiling to eliminate potential problems associated with excessive moisture in the substrate (such as slow- or non-curing of the adhesive, efflorescence on grout and porous tiles, etc).TAL X-CALIBUR X-SHIELD VAPORSTOP HB is a moisture tolerant, 100% solids epoxy barrier coat that prevents the passage of water vapour and moisture through concrete slabs. Please contact TAL for more information on the application of VAPORSTOP HB. 

 

Suspended Applications :
Tiling onto SUSPENDED concrete slabs require special precautions to be taken as the installation is prone to increased movement caused by slab deflection and creep, loading on the slab, etc. TAL BOND or TAL BOND POWDER needs to be incorporated in the adhesive and grout mix, or a single part flexible adhesive such as TAL GOLDFLEX needs to be used to allow for the increased movement.
NOTE : All Ground Floor levels with Basement / Parking levels below should be construed as SUSPENDED slabs.
