What is Vapour Curing of Semi Dry Cast Stone and what are the benefits? 

News Product Updates

Cast stone products are suitable for a wide range of applications, ranging from pier caps and copings to window surrounds and porticos. For an even longer lasting, consistent finish, however, vapour cured cast stone is the answer. Due to the specialised manufacturing process, not all cast stone companies practice vapour curing.  

Here at Amber Valley Stone we offer standard and bespoke cast stone products, with the option for vapour cured semi dry cast stone.

What is the difference? Put simply, the vapour curing process is where a semi dry cast stone unit is placed in a chamber overnight or for a set period of time, and is exposed to set curing conditions involving heat and moisture content.

This not only speeds the curing process up compared to standard air curing but also makes the stone components consistent in their finish

Units that are not vapour cured are reliant upon external, variable weather and temperature conditions that cannot be controlled. This can have an adverse effect on the quality, finish and performance of the final stone units.  

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