Product Overview

Sprayset HBP is a polymer-modified, high-build cementitious render from Fosroc formulated for application by mechanical spray equipment — typically a plastering machine or render pump — on concrete walls, masonry, block work, and rough concrete substrates. High-build renders can be applied in thicker single coats than conventional sand-cement plaster, reducing the number of coats needed to achieve the final surface profile and saving time on large area applications. The polymer modification of Sprayset HBP provides several key improvements over plain sand-cement render: higher bond strength to the substrate (including smooth or low-porosity concrete surfaces that would not accept plain cement render), greater flexibility to accommodate the differential thermal movement between render and substrate without cracking, and reduced water absorption for improved durability in external exposure. Machine spray application provides significant productivity advantages over hand application — a spray machine with a skilled operator can apply render to several hundred square metres per day, compared to 30 to 50 square metres for a skilled hand plasterer. This makes Sprayset HBP particularly valuable for large-area render applications on tall building facades, tunnel linings, and large civil engineering structures. Sprayset HBP produces a surface that can be left as the final textured finish (for industrial and infrastructure applications) or finished with a fine coat or paint system for decorative applications. Space Arc Engineering distributes Sprayset HBP for building facade, tunnel, and infrastructure rendering projects across Delhi NCR, Ghaziabad, and Northern India.

Applications

• High-build spray render for building facade and external wall finishing
• Tunnel lining and underground structure protective render by machine application
• Large-area concrete surface levelling and profiling render
• Masonry, block, and AAC wall rendering for texture and protection
• Spray render for bridge abutments and retaining wall aesthetics
• Protective render base coat for subsequent decorative or protective topcoat

Key Advantages

• High-build capability — thicker single-coat application reduces coat numbers
• Machine spray application for large-area productivity (hundreds of m2 per day)
• Polymer modification for high bond strength and flexibility
• Reduced water absorption — improved durability in external environments
• Compatible with Dekguard and Nitocote protective topcoat systems
• Factory-blended for consistent quality — just add water and spray
