Pour the grout mixture over your paving slabs and spread it evenly across the surface. Use a stiff scrubber to thoroughly work the material deep into all the gaps between the stones.

Using a scrubber to brush in grout for paving slabs involves working the dry or semi-dry mortar mixture deeply into the joints using stiff bristles before sweeping away the excess and striking the lines. This method ensures the compound packs tightly between the stones without staining the surface or leaving weak spots.

Check the depth of the gaps between the paving slabs. The joints should be cleaned out to a consistent depth, usually at least a fraction of an inch deep, to give the jointing compound enough material to bond with. If there is old, crumbling mortar remaining from previous work, scrape it out and clear the channels completely.

Ensure that the weather forecast remains dry for the duration of the work and for the curing period specified by the compound being used. Rain falling on fresh grout will wash the binding agents out of the joints and ruin the finish.

Work the Compound into the Joints

Take the stiff-bristled scrubber and begin working the compound into the gaps with firm, diagonal strokes. Moving diagonally across the joints is essential because pushing the bristles parallel to the gaps will drag the material right back out, leaving the joints half-empty.

Apply steady downward pressure as you push the scrubber back and forth across the paving. The stiff bristles will agitate the fine particles, settling them tightly into the recesses and eliminating any air pockets beneath the surface.

Take a pointing tool, a piece of suitable rounding wood, or the back of a trowel and run it along every single joint.

This action smooths the surface of the grout, creates a neat concave or flat profile, and forces the particles closer together against the edges of the paving slabs. Any excess material pushed up during this smoothing process should be brushed away immediately.

After compacting all the lines, give the entire patio one final, very light sweep with a soft brush to remove any lingering dust or stray granules from the surface of the stones. Avoid walking on the newly grouted paving until the material has had enough time to set and cure fully according to the specific setting properties of the compound you selected. Keep pets and heavy items away from the area during this crucial drying window to protect the fresh finish.
