Planning a block paving sealing job in Barry
Barry is a sizeable town with a mix of semis, terraces and newer estates, and many drives here were first laid decades ago.
Wales is wetter than most of England, and new front paving has to be permeable or drain within the property, so drainage is designed in from the start.

What you get with our sealing service
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.
- Second coat where the product requires it
- Check that the paving is clean, re-sanded and dry
- Sealer applied evenly by roller or low-pressure sprayer
- Edges, walls and doors protected
- Drying time and a date when cars can return

Sealing in Barry: questions
Will cleaning damage my block paving?
Not when it is done with a rotary cleaner at medium pressure and the joints are re-sanded afterwards. High-pressure lances held close are what cause damage.
Can you seal my drive straight after cleaning?
Only once it is completely dry and re-sanded. Sealing damp paving traps moisture and can leave a white bloom.
