Bond It Pregrit is a ready‑to‑use internal plaster bonding agent that creates a strong key on smooth, non‑porous surfaces. The formula contains added sand to ensure optimal adhesion and is pigmented yellow for easy identification. It is suitable for interior applications such as concrete, existing plaster, textured ceilings and tiles, and must not be used outdoors or in damp conditions. Apply with a brush or roller and allow at least 24 hours drying before plastering.
