Block Paving Cleaning & Re-Sanding
After block paving is jet washed, re-sanding is crucial. Learn why, what sand is used, and when sealing makes sense in Harrow.
Block paving can look brand new after jet washing—but many people miss the step that protects it afterwards: re-sanding.
Why re-sanding matters
- Locks blocks together and reduces movement
- Helps prevent weed regrowth
- Supports drainage performance
What sand is used?
Kiln-dried sand is commonly used because it flows into joints and compacts well. Re-sanding should only be done once the surface is fully dry.
What about sealing?
Sealing can enhance colour and slow staining, but it's not always necessary. It should only be done when the paving is clean, dry, and properly sanded.
