Fosroc Renderoc Hb70 20kg

Renderoc HB70 is a high-performance, polymer-modified, high-build repair mortar formulated for structural concrete restoration. Supplied as a ready-to-use blend of Portland cement, graded aggregates, specialised fillers, and chemical additives, it only requires the on-site addition of clean water to produce a consistent, high-strength mortar with excellent handling properties.

Key Features:
