Professional Patio and Driveway Protection
A driveway that holds its colour, stays clean, and doesn't turn green every spring isn't luck. It's the right sealer applied properly. Our range covers the full process from initial cleaning through to long-term surface protection:
Paving Sealers: penetrating and coating options for block paving, concrete, natural stone including black limestone, and pavers. Reduces water ingress and surface water absorption, inhibits biological growth, and provides a stain resistant finish that resists oil and general dirt.
Paving & Concrete Sealer: concrete cleaners are suited to concrete block paving and plain concrete surfaces where a protective coating is needed against surface wear, moisture, and staining. Paving cleaners are purpose-formulated for algae, moss, oil stains, and general dirt on external surfaces.
Jointing Sand: stabilises the jointing sand between block paving units to prevent weed growth and joint erosion from traffic and weather. Applied after cleaning and before sealing. Essential for long term durability on any block paved driveway.
Application Accessories: rollers with polyester roller refill options, brushes, sprayers, roller head and steel frame options. All compatible with the sealing products in this range, designed to save time and give a consistent finish on driveways, patios, and larger external surfaces.
Surface Preparation and Application Guidance
The sealer is only as good as the prep work underneath it. These steps apply across almost every surface type:
- Clean the surface properly: use a pressure washer to remove all biological growth, oil stains, loose dirt, and debris. Sealing over contamination is the most common reason protective coatings fail early.
- Let it dry fully: no sealer should go down onto a wet or damp surface. Trapped moisture under a coating causes adhesion failure. In cooler or overcast conditions, allow longer drying time than you think is needed.
- Check compatibility: not every sealer suits every substrate. A product designed for sealing block paving may not be right for natural stone or black limestone. Test on a small, inconspicuous area if unsure.
- Watch the weather: most water-based sealers should not be applied below 10 degrees Celsius or when rain is forecast within the drying window. Check the label before you start, particularly in spring when conditions can change quickly.
- Apply two coats: one coat is rarely sufficient for ongoing maintenance and long term durability. Allow the first coat to dry fully before applying the second. Over-application causes pooling and uneven finish, so work methodically across the surface.
- Wear the right PPE: chemical resistant gloves and protective goggles as a minimum.

Worth Doing Before Summer
Spring is the best window for sealing driveways and patios. Surfaces have dried out after winter, temperatures are climbing back above 10 degrees Celsius, and you've got a full season of use ahead. A clean, sealed driveway or patio makes a noticeable difference to how the whole front of a house looks. It's one of those jobs that takes a weekend and pays off for years.
Whether you're sealing block paving for the first time or just doing general maintenance on a patio that's seen better days, getting the right driveway sealer for your surface type is the most important decision you'll make before you start.
Not Sure Which Product You Need?
Surface type, condition, and exposure all affect which sealer is the right call. The difference between a penetrating sealer and a surface coating matters more than most people realise before they start. If you want a recommendation before you order, Kingfisher's technical team can advise. Contact us before you buy if you're working with an unusual substrate or a surface that's had previous treatments applied.
Frequently Asked Questions
Do I need to clean paving before sealing?
Yes, always. Sealing block paving, concrete, or any other surface over dirt, algae, or oil stains is the most common cause of early failure. Clean thoroughly, allow to dry completely, and then seal.
How long does paving sealer last?
On a well-prepared surface with the right product, several years of protection is realistic. Longevity depends on surface type, traffic, and exposure. A block paved driveway under daily vehicle use will need reapplication sooner than a lightly used patio.
Is block paving sealer suitable for all surface types?
No. A block paving sealer is not necessarily suitable for natural stone, black limestone, or a tarmac driveway. Always check product compatibility. If you're unsure, test on a small area or contact the team for guidance before committing to a full application.
How soon can I use the surface after sealing?
Light foot traffic is usually possible within a few hours of the final coat, subject to temperature and humidity. Keep vehicles off until the full curing period has passed. In cold or humid conditions, curing takes longer than the label minimum.
Can a paving sealer restore the colour of faded paving?
Many products in the range restore depth of colour to surfaces that have weathered and faded, alongside their protective function. This applies to block paving, concrete, and some natural stone. Check individual product listings for colour-enhancing properties.
What happens if paving is left untreated?
Left untreated, external surfaces absorb moisture, which accelerates cracking in cold weather, encourages algae and weed growth in joints, and causes progressive surface wear. Staining from oil and general dirt also becomes harder to remove the longer it's left. Regular sealing and general maintenance is significantly cheaper than resurfacing.
