What is included?
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.
- Drying time and a date when cars can return
- Sealer applied evenly by roller or low-pressure sprayer
- Check that the paving is clean, re-sanded and dry
- Edges, walls and doors protected
- Second coat where the product requires it
How we find the cause
- Walls, doors and planting to protect
- Moss, algae, weeds and oil staining
- Type of block and its age
- Shade and drainage, which affect regrowth
- How much joint sand is left
