Bond It Exterior PREGRIT 10L

Bond It Exterior PREGRIT 10L (SKU: BDEPG10) is a professional-grade, one-part external render bonding agent engineered to create a reliable mechanical key on exterior masonry surfaces before rendering. Formulated with fine sand aggregate, it bonds render securely to concrete, brickwork, and blockwork — including smooth and low-suction substrates that would otherwise resist adhesion. Suitable for both trade renderers and experienced DIYers tackling exterior wall preparation.

Applications

• External render bonding agent on concrete walls and soffits
• Render key coat for dense brickwork and light blockwork
• Adhesion primer for smooth or low-suction masonry substrates
• Suction equaliser on highly porous surfaces to prevent render cracking
• Pre-render preparation on existing painted or rendered exterior walls
• Exterior wall insulation (EWI) render system preparation

Why Choose This Product

Bond It Exterior PREGRIT 10L eliminates the risk of render delamination by creating a textured, aggregate-rich surface that cement-based renders grip firmly. A single coat covers approximately 30m², making it highly economical for trade volumes. The light green pigment ensures no area is missed, and the waterproof, phthalate-free formula is safe for use on occupied residential and commercial sites. Unlike SBR-only bonding agents, the built-in aggregate removes the need for a separate grit slurry coat — saving time and labour on every job.
