The wearing surface must be
- Withstand abrasion
- Resist chemical
- Resist cracking
- Minimise crazing
- Prevent delamination
- Suppress visual presence
of surface aggregate and fibres
After placement and period
of set, the concrete slab is power trowelled to provide a strong and resistant
wearing surface, after which a curing membrane will be applied and the floor
will be ready for use following the concrete design strength being achieved.
Depending on certain factors (desired appearance / type of facility /
degradation of existing wearing surface), alternative finishes can be applied
to the slab such as screeds and resin coatings, which would then be classed as
the wearing surface.
