What is the coverage per 10ltr?
A 10L tub is 15KG in weight. 1KG should cover 1.4 square metres. I have sent you the specification sheet to help.
Thin bed adhesive with enhanced non-slip characteristics. Suitable for fixing ceramic wall tiles and mosaics in dry internal locations such as kitchens and bathrooms.
Not recommended for use in permanently damp or wet locations such as swimming pools or commercial showers.
May be used in domestic showers as long as a good waterproof or water resistant grout is used and the shower area has long periods of the day where it is not in use to allow full drying to take place. Thin bed means thickness up to 3mm.
