Product Intelligence
Renderoc HB70 Plus: Technical Details, Specifications, and Features
Product Overview
Renderoc HB70 Plus is a high-strength cement-based repair mortar designed as part of Fosroc's comprehensive Renderoc concrete repair system. It is engineered for structural restoration and maintenance applications in concrete rehabilitation projects.
Key Product Characteristics
Product Classification
Renderoc HB70 Plus is a cementitious repair mortar that functions as a key component within the broader Renderoc repair system. The product is specifically formulated to meet demanding performance requirements for concrete surface restoration and structural repair work.
System Integration
Renderoc HB70 Plus operates within a coordinated concrete repair and protection strategy:
- Primer Requirements: The product requires Nitobond HAR as the essential primer for application and to achieve optimal bond strength with concrete substrates
- System Compatibility: It integrates with Nitoprime Zincrich primer and other complementary bonding and curing products
- Application Method: Renderoc HB70 Plus is applied to the tacky surface of Nitobond HAR primer after it becomes tacky on the substrate, ensuring superior adhesion
Critical Specification: Curing Requirements
Curing Compound Limitations
An important specification of Renderoc HB70 Plus is its curing compound compatibility:
Do not use Nitobond AR as a curing membrane for Renderoc HB70 Plus. For this product, use Concure A99 curing compound instead.
This distinction is critical for ensuring proper curing, material integrity, and performance characteristics of the finished repair.
Application Context
Renderoc HB70 Plus is positioned as a high-strength alternative repair mortar within the Renderoc product family. It serves concrete structures requiring robust repair solutions, including applications where superior compressive strength and durability are essential for long-term structural performance.
