£56.48Patio Grout is unique & proven to be the best 1-part paving joint grouting product on the market, and is designed for ease of use by Professionals & competent DIY’ers!
Patio Grout is unique and has big advantages – It is easier and faster to apply, because it allows the most efficient and effective use of wet slurry application, which provides optimum self-compaction into the joints, with no additional tooling or finishing required, and minimal cleaning with no oily film or residue. Patio Grout is also outstanding in comparison with other air-drying, 1-part, paving joint compounds, because of its higher compressive, flexural tensile and cohesive strengths, strengths correlation and higher adhesive bond for better performance in service.
Patio Grout is designed for Professional and DIY use on domestic paving with pedestrian traffic, i.e., for garden patios, pathways, and terraces etc. It is suitable for grouting most types of external natural stone and concrete paving, including smaller format e.g. setts, cobbles, and brick pavers, plus larger format slabs, and flags.
Patio Grout is suitable for use on both new paving & paving repointing projects.

After an initial few minutes the surfaces are finished with a coconut brush and final rinse with clean water to remove any excess. (Note – the freshly grouted surfaces must be covered and protected if more rain is expected, or alternatively use the latest state-of-the-art GftK vdw 850+ that can even be applied in the pouring rain e.g. when needs must to finish a job and/or get paid!)
