Sealing Block Paving: Is It Worth It?
Block paving is a popular choice for driveways across Ashtead, Surrey. It offers durability, flexibility and strong visual appeal. However, once installed, many homeowners ask whether sealing the surface is a worthwhile investment or simply an optional extra.
At NS Driveways Ashtead, we regularly advise property owners in Ashtead on the long-term care of their block paving. Sealing is not always essential, but in the right circumstances it can provide meaningful benefits.
What Does Sealing Block Paving Involve?
Sealing involves applying a specialist protective coating over clean, dry block paving. This sealant penetrates the surface and forms a protective barrier.
The process typically follows:
- Thorough cleaning of the paving
- Removal of moss, algae and surface debris
- Re-sanding of joints where required
- Even application of the sealant
When carried out correctly, sealing enhances both the appearance and resilience of the driveway.
The Potential Benefits of Sealing
Protection Against Staining
Driveways are exposed to vehicle fluids, tyre marks and general dirt. A quality sealant reduces the porosity of the blocks, helping to prevent oils and contaminants from soaking into the surface.
This can make routine cleaning easier and preserve the appearance of the paving.
Reduced Weed Growth
While sealing does not completely eliminate weeds, it can help limit growth by stabilising jointing sand and reducing moisture penetration between blocks.
In Ashtead, where driveways are exposed to seasonal rainfall, maintaining stable joints can contribute to a neater surface.
Enhanced Colour and Finish
Some sealants subtly enrich the natural colour of the blocks, restoring vibrancy that may have dulled over time.
For homeowners keen to maintain kerb appeal, this visual enhancement can be particularly appealing.
Improved Surface Stability
Sealing helps bind the kiln-dried sand between blocks, which can reduce minor movement. Although it does not replace proper installation, it can support the long-term integrity of a well-laid driveway.
When Is Sealing Most Worthwhile?
Sealing is typically most effective when:
- The block paving is in good structural condition
- The surface has been professionally cleaned
- Jointing sand has been properly reinstated
- The paving has had time to settle after installation
Applying sealant too soon after installation or over a poorly prepared surface can compromise results.
Situations Where Sealing May Not Be Necessary
If block paving is already structurally sound and regularly maintained, sealing is not always essential. Some homeowners prefer the natural weathered appearance of unsealed paving.
The key consideration is whether added protection and enhanced appearance align with your long-term plans for the property.
The Importance of Professional Application
Incorrect application can lead to patchy finishes, trapped moisture or surface whitening. Proper surface preparation and controlled application are critical.
