Block paving sealing in Penarth: what to expect
Penarth is a smaller town, and many of its homes have more frontage to work with than city houses, which leaves room for borders and planting.
Hilly streets in much of Wales mean many drives slope, which shapes the falls, the edging and the water route.

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.
- 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
- Edges, walls and doors protected
How we find the cause
- Walls, doors and planting to protect
- Moss, algae, weeds and oil staining
- Whether the paving is permeable (no sand, no sealing with the wrong product)
- Type of block and its age
- Whether any blocks are loose or sunken first
