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