Technical Data
For technical data please refer to the datasheet PDF.
Constraints
Not suitable if the grout is required to be chemically resistant or completely impermeable.
Preparation
Ensure that the adhesive has set and dried and that the tiles are firm.
Adhesive should normally be left for at least 24 hours before grouting, unless using a rapid set adhesive, when it should normally be left for 2 – 3 hours. Longer may be required on sealed and impervious surfaces.
For swimming pools, leave for at least 3 days before grouting.
Ensure the tiles and joints are clean, dry, and free from adhesive, grease or any other contamination. If necessary, seal natural stone and allow to dry.
If the grout is required to be completely impervious to water, or chemically resistant, use weber.joint epoxy.
Mixing
It is recommended that a low-speed mechanical mixer is used. The mix ratio is approx. 3 parts of grout to 1 part water by volume (normal usage requires 1.5 litres per bag). Add the powder gradually to clean water and mix to a smooth stiff paste. Allow to stand for 5 minutes and re-mix thoroughly.
Do not re-wet, over-water or use as a sloppy grout mix as this will cause weakness and discolouration.
Application
Please see datasheet PDF for application details.
Storage and Shelf life
When stored unopened in a cool, dry place at temperatures above 5°C, shelf life is 12 months from date of manufacture. If stored longer, setting times will increase.
