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.
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
- Edges, walls and doors protected
- Second coat where the product requires it
- Sealer applied evenly by roller or low-pressure sprayer
How we find the cause
- Which sealer finish suits a slope or patio
- Type of block and its age
- Whether any blocks are loose or sunken first
- Moss, algae, weeds and oil staining
- Whether the paving is permeable (no sand, no sealing with the wrong product)
