Frequently asked questions - Patio Sealing

What does patio sealing actually do?

Sealing adds a protective layer to your paving that repels water, resists oil and grease stains, and makes it much harder for algae, moss, and lichen to take hold. It won’t stop weathering completely, but it significantly slows down the rate at which dirt, spills, and organic growth work their way into the surface.

Do I need to clean my patio before sealing it?

Yes, always. Sealing over dirt, algae, or old moss traps it under the sealant, which can actually make staining worse and shorten the life of the seal. A thorough clean and full dry-out period is essential before any patio sealing services are carried out.

How long does a sealed patio last before it needs redoing?

This depends on the sealant type, the paving material, and how exposed the area is to weather and foot traffic. Solvent-based sealants tend to last longer than water-based ones, but most UK patios need resealing every 2-5 years to keep the protection effective.

Will sealing make my patio slippery?

A good quality sealant shouldn’t make the surface dangerously slippery, especially if a matt or textured finish is used rather than a high-gloss one. For commercial properties or areas prone to rain, we’d always recommend a slip-resistant additive as part of the sealing process.

Can sealing help prevent moss coming back?

Sealing creates a much less hospitable surface for moss spores to establish themselves, so paver patio moss removal tends to be needed far less often once a patio has been properly sealed. It’s not a permanent barrier, but it buys you significantly more time between deep cleans.

Does sealing change the colour or look of my patio?

Some sealants enhance the natural colour of the stone and give it a slightly richer, “wet look” finish, while others are designed to be completely invisible. We’ll usually test a small patch first so you can see the effect before committing to the whole area.

Is patio sealing worth it for a driveway too?

Definitely. The same principles that protect a patio apply to driveways, and combining the two into a wider paver driveway maintenance routine tends to save money and keeps a consistent finish across your whole outdoor space.

How soon can I walk or drive on a newly sealed surface?

Foot traffic is usually fine within 24 hours, but full curing (especially for driveways that need to take vehicle weight) can take anywhere from 48 hours to a week depending on the product and weather conditions. We’ll always confirm exact timings based on the sealant used.

Can commercial properties benefit from patio sealing?

Yes, particularly outdoor dining areas, hotel courtyards, and public walkways where appearance and slip safety both matter. Sealing reduces the frequency of maintenance visits needed and helps commercial paving stay presentable between scheduled cleans.

Should I seal my patio myself or hire a professional?

DIY sealing kits exist, but even coverage is harder to achieve than it looks, and missed patches or over-application can lead to patchy results or a cloudy finish. Professional patio sealing services use commercial sprayers and know the correct number of coats and drying times for your specific stone type, which tends to give a longer-lasting, more even result.
