Curing

The correct curing of cast stone is essential to resist damage during transportation and construction, and for its long-term durability and appearance.

The minimum curing time specified in the British Standard is 14 days after casting, unless accelerated curing methods are employed. The 14 day period – which may need to be extended for structural units – comprises the initial curing period of 12-14 hours away from direct sunlight and drying winds, then storage before dispatch.

However, some UKCSA members have invested in an accelerated curing method, usually referred to as vapour curing, a technique which can significantly reduce the timescale required from production to site.

All UKCSA members must achieve a minimum level of curing, as defined in UKCSA's Curing Regimes & Standards document.
