Block paving is one of the most popular driveway and patio surfaces in the UK. But should you seal it after cleaning? Let's explore the benefits, costs, and considerations.
What is Block Paving Sealing?
Sealing involves applying a protective coating over your block paving after it's been professionally cleaned. The sealant penetrates the surface and forms a protective barrier against the elements.
Benefits of Sealing Block Paving
1. Enhanced Colour
Sealing brings out the natural colours in your blocks, giving them a fresh, vibrant appearance. You can choose from natural, matte, or wet-look finishes.
2. Weed Prevention
Sealed joints make it much harder for weeds to take root between your blocks. Combined with proper re-sanding, this can dramatically reduce maintenance.
3. Oil Stain Resistance
Sealed surfaces are much easier to clean. Oil and other spills sit on top of the sealant rather than soaking in, making them simple to wipe away.
4. Reduced Moss and Algae
Sealants make the surface less hospitable for organic growth, meaning your paving stays cleaner for longer.
5. Joint Stabilisation
Sealants help bind the kiln-dried sand in the joints, preventing it from washing out in heavy rain.
Types of Block Paving Sealant
- Matte/Natural finish - Protects without changing appearance
- Wet-look finish - Darkens and enhances colours
- Gloss finish - Maximum colour enhancement with shine
How Much Does Block Paving Sealing Cost?
Prices typically start from £4-8 per square metre for sealing, on top of cleaning costs. A typical driveway of 40-60m² might cost £200-500 for sealing alone.
Is It Worth It?
Sealing is worth considering if:
- Your paving is relatively new or in good condition
- You want to reduce ongoing maintenance
- Colour enhancement is important to you
- You have problems with weeds or moss
It may not be worthwhile if:
- Your paving is very old or damaged
- You're planning to replace it soon
- Budget is a significant concern
