1
With proper construction based on ASTM requirements for cast stone concrete products, precast is virtually maintenance-free.
2
Maintenance equipment needed includes a commercial concrete cleaner containing a chlorine solution, rubber gloves, a soft brush, and a garden hose.
3
After spraying the cast stone thoroughly with water, the concrete cleaner is carefully applied using rubber gloves. A soft brush can be effective in removing stubborn stains.
4
Corrosion will be prevented when open joints and surfaces with sealants do not come in contact with the cleaner.
5
Avoidance of metal brushes, acids, power washing, and sandblasting techniques will prevent damage to the cast stone and keep it pristine and looking new.
