SURFACE PREPARATION
General
Ensure surfaces to be tiled are flat, clean, dry, sound, free from contamination and all barriers to adhesion.
Surface regularity:
Surface Regularity is defined as the deviation in height of the surface over short distances in a local area. In simpler terms, it is the ‘flatness’ or ‘measure of unevenness’ of the wall surface.
Class | MAXIMUM PERMISSABLE DEVIATION FROM a 2M STRAIGHT EDGE (MM) | APPLICATION |
SR1 | 3mm | Recommended for direct fixing of tiles and slabs with a tile adhesive |
In domestic wet areas: waterproof background
NOTE: Drying times will be extended, i.e. leave adhesive to dry for a minimum of 3 days at 20°C before grouting with BAL ABSOLUTE GROUT.
SUITABLE SURFACES include:
Plaster (finish coat only)
Must be at least 4 weeks old before tiling. Ensure that the plaster is free from dust, laitance and friable material.
If plaster is shiny or polished, brush thoroughly with a stiff bristled brush before priming with 1 coat of
– BAL PRIME APD (diluted 1:1 by volume with clean water)
– BAL BOND SBR (diluted 1:4 by volume with clean water) Allow primer to dry.
Weight restriction for tiling onto plaster is a maximum weight of 20kg/m2.
NOTE: When primed, drying times will be extended, i.e. leave adhesive to dry for a minimum of 3 days at 200C before grouting.
Plasterboard
Ensure boards are dry, securely fixed and rigid and suitable thickness used.
NOTE if the plasterboard is dot and dabbed at 300mm centres and around the perimeter, leave to dry before fixing tiles. Weight restriction for tiling onto plasterboard is a maximum weight of 32kg/m2. NOTE: To improve the weight restrictions use BAL BOARD (maximum 100kg/m2).
Clay Brickwork/dense concrete
Allow new block mortar to dry for minimum 6 weeks before rendering e.g. BAL QUICKSET RENDER or plastering
Lightweight blockwork/walling
Allow new block mortar to dry for minimum 6 weeks before rendering e.g. BAL QUICKSET RENDER, plastering or fixing BAL BOARD for internal areas (see BAL TECHNICAL DATA SHEET on BAL BOARD for further information).
NOTE: Direct fixing of tiles to lightweight blockwork is NOT recommended.
Cement:sand renders
Before tiling, ensure that the substrate is flat (SR1), free from efflorescence, laitance, dirt, polished concrete and other loose materials. Remove by using suitable mechanical methods
Allow the following minimum drying times:
BAL Green Star backgrounds
Clay Brick / Medium Density Concrete Render (2) (5) | ✓ | Plaster (2) (3) | ✓ |
Rendering (2) | ✓ | Plasterboard (3) (4) | ✓ |
Tile Backer/Fibre Cement Boards 3)(4)(6) | ✓ | Unglazed Ceramic Tiles / Hard Natural Stone | ✓ |
Glazed Tiles (6) | ✓ | Lightweight Blockwork with Render (2) (5) | ✓ |
Painted Surface (6) | ✓ | Waterproof Backgrounds (6) |
(1) Tiles must be grouted using BAL ABSOLUTE GROUT.
(2) Provided the surface is sufficiently flat.
(3) In wet conditions tank out with BAL TANK IT or BAL WATERPROOF 1C
(4) Check suitability for the intended purpose with the Manufacturer or check BAL TECHNICAL DATA SHEETS on any BAL Products.
(5) Apply a cement: sand render e.g. BAL QUICKSET RENDER or a suitable tile backing board prior to tiling.
(6) Drying times will be extended, i.e. leave adhesive to dry for a minimum of 3 days at 20°C before grouting.
Note:
(a) Do not use shower for at least 2 weeks after completion of grouting – BS 5385:Part 4

For BAL QUICKSET RENDER and BAL QUICKSET CEMENT: rendering please see the relevant Technical Datasheets
– Rendering (bonded): 4 hours**
Applying a BAL BOND SBR SLURRY
**1 part sand to 1 part BAL QUICKSET CEMENT by weight, mixed with appropriate amount of BAL BOND SBR pre- diluted1:1 with clean cold water by volume to achieve desired consistency.
Check BAL QUICKSET CEMENT and BAL QUICKSET RENDER Technical Datasheets for drying and fixing times.
Existing glazed ceramic tiles/glazed bricks
Ensure existing tiles/bricks are soundly bonded to a stable background that is sufficiently strong enough to support the weight of the new tiling.
If areas are loose or hollow-sounding, remove and make good with BAL QUICKSET RENDER or 1:3 cement:sand mortar over a slurry bonding coat (See above)
NOTE: Drying times will be extended, i.e. leave adhesive to dry for a minimum of 3 days at 20°C before grouting.
Fibre reinforced cement boards and lightweight tile backer boards
Install boards to BS 5385 (i.e. moisture-resistant boards such as BAL BOARD), and screwed to seasoned timber or suitable proprietary framework at maximum 300mm centres vertically and horizontally or as per the board manufacturer’s recommendations (see BAL TECHNICAL DATA SHEET on BAL BOARD for further information).
Ensure no fixings protrude.
Do NOT seal or prime surface to be tiled.
IMPORTANT NOTE: Obtain manufacturer’s confirmation that boards are suitable for the tiling application and for relevant fixing instructions.
Painted surfaces
Remove all loose and flaking paint.
Check by applying a suitable self-adhesive tape to clean dry paint surfaces. Tear off tape after 10 mins. If paint is removed with the tape, the paint is unsound.
Remove unsound paint mechanically. Do NOT use paint strippers.
NOTE: Drying times will be extended, i.e. leave adhesive to dry for a minimum of 3 days before grouting. It may be required to overboard the surface with a suitable tile backer board, such as BAL BOARD. Wet area – remove paint and tank
Grouting
1. Waiting minimum 24 hours (at 20°C) after tile fixing. Select a BAL cementitious or epoxy grout
NOTE: If tiling on an impervious background delay grouting for min. 3 days, to allow for extended setting time.
NOTE: Follow guidelines to BS Standards (minimum 2mm joints for walls, size can change depending on size of tile and environments), Contact BAL TECHNICAL ADVISORY AND SPECIFICATION SERVICE for more information.
APPLICATION/USAGE
Do NOT use in temperatures below 5°C or in damp conditions.
If fixing onto a non- porous background (e.g. tiles), drying times will be extended.
For larger size tiles use a cementitious adhesive from the BAL range. Contact BAL TECHNICAL ADVISORY AND SPECIFICATION SERVICE for more information.
BAL Green Star trowel recommendations
Area | Trowel |
---|---|
Internal Dry Wall Area (up to 300x300mm tiles) | Max 6mm Notched Trowel |
Internal Wet Wall Area (up to 300x300mm tiles) | Max. 6mm Notched Solid Bed Trowel |
Mosaics (up to 100x100mm tiles) | Min. 4mm Notched Trowel |
NOTE: ensure you achieve the correct amount of adhesive to both the background and tile in line with BS 5385, Parts 1-5.
BAL Green Star Fixing procedure
1. Apply adhesive to wall surface and comb to required bed thickness ensuring the ribs of adhesive all run in one direction.
If fixing large ceramics (300 x 300mm – or equivalent surface area of tile up to 0.09m2 i.e. 450 x 200mm, 600 x 150mm), /heavily-patterned tiles, apply additional adhesive to tile reverse (Apply a maximum of 3 mm thickness).
2. For mosaics: using a rubber tile float, press mosaics into adhesive and beat into required position, ensure joints between sheets match joints between mosaic tesserae (i.e. staggered).
For tiles: press tile firmly into the ribs of adhesive and into position, with slight twisting/sliding action to ensure optimum adhesive contact.
3. Fix mosaics/tiles before adhesive forms skin If skin has formed, remove adhesive and apply fresh layer).
4. Occasionally lift a mosaic/tile to check adhesive contact is min. 75% coverage for dry areas; min. 100% coverage for wet areas (i.e. leave no voids behind tiles).
5. Leave adequate joints between individual tiles unless self- spacing tiles used.
6. Install movement joints in accordance with BS 5385, Parts 1-5.
7. Clean off surplus adhesive from tile face and between tile joints before the adhesive has dried.
2. Fill movement joints and seal around bath/shower trays with suitable sealant i.e. BAL MICROMAX SILICONE SEALANT. Do NOT use on sensitive surface that could react to acetic acids released during cure.
If completing a shower, do NOT use shower for at least 2 weeks (as required by BS 5385: Part 4
