How It Works

Rock-Tite Brush-In Grout is swept into prepared joints between paving slabs where it locks into place and air cures to form a durable, permeable joint. Its cement-free formulation ensures flexibility and reduces the risk of cracking while maintaining long-term stability.

Application Guidance

Apply the grout by brushing it into clean, dry joints between paving slabs. Ensure joints are fully filled and compacted. Any excess material should be brushed off the surface and can be reused where required.

Leftover product can be stored by covering with water to a minimum depth of 50mm above the surface, helping to maintain usability for future applications.
