What does a block paving sealing job involve?

Sealing only works on paving that has been cleaned and re-sanded first and is completely dry, so it is usually part of a clean, re-sand and seal package. It is not permanent: most sealers need renewing every three to seven years as they wear in the wheel tracks, and new paving should be left for a few months before sealing so moisture and any white efflorescence can clear.

Hilly streets in much of Wales mean many drives slope, which shapes the falls, the edging and the water route.

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

How we find the cause

  • Shade and drainage, which affect regrowth
  • Which sealer finish suits a slope or patio
  • How much joint sand is left
  • Walls, doors and planting to protect
  • Whether any blocks are loose or sunken first

Not when it is done with a rotary cleaner at medium pressure and the joints are re-sanded afterwards. High-pressure lances held close are what cause damage.
