DESCRIPTION:
AT-SURTARD 504 is a surface retarder for exposed aggregate finish. It retards the hydration of cement at the surface. When subsequently washed off, the aggregates are exposed.
USES:
- AT-SURTARD 504 provides mechanical key for subsequent operations
- AT-SURTARD 504 provides exposed aggregate finish where architectural finish is required
ADVANTAGES:
- Scrabbling of concrete is eliminated
- Can be used in all type of form-works
- Gives desired results in high temperature concreting
- Labour cost is reduced
- Non-hazardous, non-toxic
COVERAGE:
- 0.100 kg – 0.200 kg/m2 depending on the surface and porosity of form-work.
APPLICATION:
- AT-SURTARD 504 should be stirred well before use.
- It can be applied by brush, roller or spray.
- It has to be applied on clean, uncontaminated form-work. For highly absorbent formwork, minimum 2 coats have to be applied for effective / desired performance.
- Before pouring of concrete in the mould, AT-SURTARD 504 should be dry.
- Remove form-work as quickly as possible and wash off concrete surface with a strong water jet.
- Depending upon the rate of application the depth of exposure can be 4 mm to 10 mm on the concrete surface.
