What does a block paving sealing job involve?

Sealing block paving means applying a clear liquid sealer to clean, dry paving. A good sealer soaks into the blocks and the jointing sand, binding the sand so it does not wash out, reducing staining and making the surface easier to keep clean. Some sealers also deepen the colour or leave a light sheen.

  • Check that the paving is clean, re-sanded and dry
  • Second coat where the product requires it
  • Sealer applied evenly by roller or low-pressure sprayer
  • Edges, walls and doors protected
  • Drying time and a date when cars can return

How often should block paving in Welling be cleaned?

Every two to four years for most drives, more often for shaded or north-facing paving.
