Fosroc Renderoc Cac Wetspry

Renderoc CAC Wet Spray is a high-performance, calcium aluminate-based cementitious mortar designed for the rehabilitation and protection of sewer infrastructure exposed to biogenic corrosion. Its formulation combines calcium aluminate cement and aggregates to provide exceptional resistance to the aggressive conditions typically found in wastewater environments.

Key Features:

• Outstanding resistance to biogenic corrosion – ideal for sewer environments

• Inhibits bacterial activity and neutralizes sulfuric acid

• Excellent adhesion to damp concrete surfaces

• Long-term durability in high-moisture and corrosive conditions

• VOC-free – environmentally friendly and safe for confined space use

• Compatible with existing sewer infrastructure and new construction

Typical Uses:

• Structural repair and lining of corroded sewer manholes, pipes, chambers, and tunnels

• Protective lining for new wastewater infrastructure

• Environments where resistance to chemical attack and high moisture is critical

Application Method:
Applied using wet spray equipment for rapid and consistent coverage in vertical and overhead applications.

Packaging:
Available in 25kg bags

Coverage:
Approximately 13 litres per 25kg bag (depending on thickness and site conditions)

Compressive Strength:
Typically ≥ 50 MPa at 28 days
