BAL Grout Flex Wide Joint Tile Grout is a highly flexible, water/frost-resistant cementitious tile grout for floors and walls. Available in 5 colours: White, Jasmine Cream, Light Grey, Mid Grey, Dark Grey. Comes in either 10kg or 5kg bags. Sets in 24 hours (at 20°C).
BAL Grout Flex Wide Joint Tile Grout can be used for:
- Grouting porcelain, glazed and fully vitrified, glass and ceramic mosaics, marble and natural stone in dry and wet interior and exterior environments. Follow guidelines to BS Standards (minimum 2mm joints for walls and 3mm for floors, size can change depending on size of tile and environments), Contact BAL TECHNICAL ADVISORY AND SPECIFICATION SERVICE for more information.
- For Joint widths: 3mm to 20mm.
- Recommended for swimming pools (hard water), and for limited movement areas including overlaid plywood floors (minimum 15mm) and heated screeds.
Restrictions: BAL Grout Flex Wide Joint Tile Grout is NOT suitable for:
- *Food preparation/*storage areas, * Spas, * Jacuzzis, *Chemical Plants, Power Showers with body jets and areas requiring *waterproof grouting. *These applications are better suited to a BAL EASYPOXY AG Grout.
Powder/Water Ratio: 5:1 (by weight)
Pot Life at 20°C: 2 hours
Cure Time at 20°C: 24 hours. Drying time will be extended in colder temperatures, when fixing to impervious backgrounds or when fixing tiles of low porosity.
Specific Gravity: 1.89/cm³
Before grouting, ensure that:
- Tile adhesive has fully set, as indicated on adhesive packaging or BAL Technical Data Sheet.
- Open joints clear from excess adhesive and are protected from contamination – and are clean, dry and free from loose debris.
- Be consistent with the amount of clean cold water used with the cement-based grout from mix to mix when grouting larger areas.
- Lighting conditions during the installation of tile fixing and grouting should not be ‘appreciably different’ from the final (permanent) lighting. Where possible, check the grout colour with the final lighting conditions.
- Check colour consistency when using the same grout when applied between different tile types i.e. porous bodied or porous stone tiles vs. porcelain or denser stone.
IMPORTANT NOTE: Do NOT use BAL Grout Flex Wide Joint Tile Grout in temperatures below 5°C or in damp conditions.
If grouting porous tiles in temperatures above 25°C, dampen joints with clean water prior to grouting. If grouting externally, provide protection against inclement weather during grouting and for as long as possible afterwards. It is recommended that all external tiling applications include a DPM or a surface DPM can be applied prior to tiling (e.g. BAL DPM).
If grouting a shower installation, BAL Grout Flex Wide Joint Tile Grout is water-resistant but NOT impervious to water and not a substitute for waterproof systems.
– Provide waterproof tanking protection for all tiling background substrates (e.g. by using BAL Tank -It or BAL Waterproofing Kit For Showers).
– Ensure tiles are fixed with a solid bed with a water-resistant adhesive (e.g. BAL White Star Plus, BAL Flex One / BAL Flex Fibre Plus or BAL Rapid Flex One / BAL Rapid Flex Fibre Plus).
- Use a BAL Mixing Bucket or other suitable bucket. Slowly add approximately 5 parts powder to 1-part clean cold water by weight. (see table). Never add more water than recommended as this may lead to colour inconsistencies in the finished grout.
- Mix until lump-free mortar achieved.
- Allow mixed grout to stand for 2-3 minutes before re-mixing for 30 seconds. No further water should be added after original mixing. Avoid entraining air by mixing at too high speed.
- Check potential staining risk: apply grout to a few tiles in small trial area. If discolouration occurs or difficulties are encountered with cleaning off (surplus grout), apply BAL Protective Sealer – and repeat trial.
- Work in small areas with a grout float or squeegee. Completely fill tile joint with mixed grout and compact well, removing excess grout from tile surface as work proceeds.
- Allow approx. 15minutes for grout to dry (at 20°C) or when the surface of the grout joints is dry enough to be touched (NOT fully set/cured).
- Using a dampened sponge or sponge board, clean surface diagonally to grout lines. Use as little water as possible to wash off the grout but rinse out sponge/sponge board frequently with clean water. NOTE: Do NOT allow water to enter un-grouted joints.
- When grout has set sufficiently within joints, polish tile surface with dry clean cloth.
- Clean any remaining light haze from the surface next day, using water and a white emulsifying pad and gripper.
- Wait minimum 24 hours before subjecting tiles to normal service conditions.
NOTE:If completing a swimming pool, do NOT fill pool for at least 3 weeks after grouting (contact BAL Technical Advisory Service for further advice).
If completing a shower, do NOT use shower for at least 2 weeks.
