Bond It Gripbond GB Pro Hybrid Sealant & Adhesive

Bond It Gripbond GB Pro is a hybrid polymer sealant and adhesive that does two jobs at once. It forms a tough, elastic rubber joint where a flexible sealant is needed, and it bonds directly to most building materials where a high-strength adhesive is required. This means fewer tubes on the van and fewer decisions on site. The product is solvent-free, isocyanate-free, and has no noticeable odour, which makes it a practical choice for enclosed spaces and occupied buildings.

Gripbond GB Pro adheres to a wide range of surfaces including concrete, stone, ceramics, wood, glass, copper, lead, zinc, aluminium, stainless steel, PVC, polycarbonate, polystyrene, and gypsum board. It also bonds to mirrors that have an acetone-resistant backing. Crucially, it will adhere to moist surfaces, which is useful when conditions on site are less than ideal. Wet-on-wet application means the product can be applied to a damp substrate without waiting for it to fully dry first.

Where Gripbond GB Pro Performs as a Flexible Sealant and Adhesive

This product is suited to both interior and exterior applications across a broad range of trades. It is used by builders, joiners, plumbers, roofers and general fixers who need a reliable all-in-one product for sealing joints, bonding panels, or securing materials where movement is likely. Because it remains permanently flexible once cured, it can handle the expansion and contraction that comes with temperature changes or structural movement without cracking or losing adhesion.

Gripbond GB Pro is CE approved and conforms to EN15651-1 F INT, which confirms it meets established standards for construction sealants. It is non-staining and will not discolour most surfaces, making it a reasonable choice for use on natural stone and marble. That said, natural stone varies considerably in porosity, so testing in an inconspicuous area before full application is always worthwhile. A primer may also help where the stone is particularly absorbent.

Overpaintable and Clean to Use

Once cured, Gripbond GB Pro can be overpainted with water-based paints, which matters when the joint needs to disappear into a finished surface. The coloured versions of this product also carry anti-pick properties, which is useful in public-facing or accessible areas where sealant joints are sometimes tampered with. Clear, white, grey, brown, and black variants are available to match common substrates and finishes.

The formula contains no silicone, no phthalates, no solvents and no isocyanates. This keeps it compatible with a wider range of surfaces than traditional solvent-based adhesives, reduces health and safety concerns during application, and means it will not cause staining or surface damage on sensitive materials. For anyone regularly working with natural stone, render, or painted surfaces, that combination is genuinely useful rather than just a specification box tick.
