Sprayset HBL is a chloride free liquid based on a blend of inorganic powders, which is added to a sprayed concrete mix to impart properties of high build and low rebound. Used to enable a high build of sprayed concrete, shotcrete and gunite without slump and provide set acceleration and reduce rebound.
- High build enables faster coverage with minimised slump.
- Can be applied up to 300mm in one application to vertical surfaces and up to 200mm overhead dependant on weight / volume of aggregate
- Non caustic leads to safer handling / operating conditions
- Low rebound - controlled set allows new material to be embedded in applied concrete mixture.
- Chloride free liquid
- 28 days strength not adversely affected
