How to Grout – Brought to you by BAL Adhesives and Grouts
Every beautiful tile needs a complimentary grout to make them stand out. To ensure the perfect finish to your tiling project, follow the below steps on how to grout:
Step 1 – Ensure your grout lines are clean
- When tiling a wall or floor, make sure your grout lines are clean and free from any excess tile adhesive as this can interact and discolour your adhesive.
- Clean any excess off the tile surface and grout lines using a damp sponge
- All grout lines should be clean, dry and free from loose debris.
Step 2 – Make sure your adhesive has fully dried
- Check the adhesive manufacturer’s instructions on set-time. Typically, ready-mixed adhesives like BAL WHITE STAR PLUS take 24 hours to set, rapid-setting adhesives such as BAL RAPID-FLEX ONE or BAL FLEX ONE anything from 3-6 hours, and standard sets such as BAL SINGLE PART FLEXIBLE from 16 hours plus.
- Remember set-times will vary depending on environmental conditions i.e. adhesives will set slower in cooler temperatures and quicker in hotter conditions.
Step 3 – Remove all spacers
- It is absolutely crucial to remove any spacers which are still embedded in your adhesive, or punch them fully into the tile adhesive bed before grouting.
- Failure to remove spacers before grouting, can lead to grout lines cracking.
Step 4 – How to grout porous tiles in hotter temperatures
- If grouting porous tiles in temperature above 25°C, dampen joints with clean water prior to grouting.
Step 5 – How to mix BAL grouts
- Using a mixing bucket, slowly add the powder to clean cold water at a ratio as per the bag instructions.
- Mix using a bucket trowel or electric drill mixer at a slow speed (under 300rpm) until lump-free mortar is achieved.
- Allow the mixed grout to stand for 2-3 minutes before remixing for 30 seconds. Avoid entraining air by mixing at a two high speed or by over mixing.
Step 6 – Check potential staining risks
- Apply grout to a few tiles in a small trial area. If discolouration occurs, or difficulties are encountered with cleaning off (surplus grout), apply BAL PROTECTIVE SEALER and repeat the trial.
Step 7 – How to apply the grout
- Work in small areas with a grout float or squeegee, holding it at 45° Completely fill the tile joint with mixed grout and compact well, removing any excess grout from the tile surface as work proceeds.
- Allow the grout to dry until it is touch dry (not fully set/cured). This can be anything up to 20 to 30 minutes.
- Using a dampened sponge or sponge board, clean surface diagonally to the grout lines. Rinse out the sponge/sponge board frequently with clean water – do not over wash!
- Do not allow water to enter un-grouted joints.
- When the grout has sufficiently set in the joints, polish the tile surface with a clean, dry cloth.
Step 8 – Final clean down
- Clean any remaining light haze from the surface the next day using water and an emulsifying pad.
- Wait a minimum of 24 hours before subjecting tiles to normal service conditions.
- If grouting a shower, do not use the shower for at least 2 weeks as per British Standards.
