What is included?
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.
Flat ground across much of the East means falls have to be built in carefully so water does not sit on the drive.
- Edges, walls and doors protected
- Sealer applied evenly by roller or low-pressure sprayer
- Second coat where the product requires it
- Check that the paving is clean, re-sanded and dry
- Drying time and a date when cars can return
