What you get with our sealing service
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.
- Sealer applied evenly by roller or low-pressure sprayer
- Edges, walls and doors protected
- Drying time and a date when cars can return
- Second coat where the product requires it
- Check that the paving is clean, re-sanded and dry
How we find the cause
- Which sealer finish suits a slope or patio
- Whether the paving is permeable (no sand, no sealing with the wrong product)
- How much joint sand is left
- Shade and drainage, which affect regrowth
- Moss, algae, weeds and oil staining
