Remove enough old joint material to meet the replacement product’s requirements without disturbing a sound bedding layer

There is no safe universal fraction of paver depth that applies to every re-sanding project. The required removal depends on the new joint product, joint width and depth, the condition and type of existing material, and whether the pavement is otherwise stable. Loose, contaminated, incompatible, or failed material should not simply be topped with a thin new layer.

Inspect the pavement before treating it as a joint-maintenance problem

Rocking, settlement, spreading edges, or repeated sand loss can indicate base, drainage, or edge-restraint issues. Re-sanding alone will not correct those failures.

Test the removal method in a small area

Pressure, vacuuming, or other cleaning methods can chip edges, etch surfaces, or wash out bedding if used aggressively. A test area helps establish the removal depth and cleaning approach before the entire patio or driveway is exposed.

Prepare for the specific replacement sand

The joints and surface may need a particular moisture condition, compaction sequence, refill process, cleaning standard, and activation method. Follow the written instructions for the selected product rather than applying a generic re-sanding routine.

Do not remove sound material unnecessarily

Excessive excavation of the joints can destabilize units or expose bedding that was performing correctly. The objective is to create enough clean joint depth for the new material to perform, not to empty every joint to the bottom by default.

Use one sample area as the acceptance standard
