How Durable is Block Paving Sealant

Sealing a block paving driveway or patio is an investment of time and money, so it’s natural to want to know how long it will last. The good news is that a quality block paving sealant is built to go the distance, protecting your paving for years with very little upkeep. Here’s how durable block paving sealant really is, what affects its lifespan and how to get the most from it.

How long does block paving sealant last?

Resiblock Superior Matt and Superior Gloss protect block paving for up to five years. Once applied, they bind the jointing sand and form a tough, flexible protective layer over each block, so you’ll only need light seasonal cleaning to keep the surface looking its best.

What affects how long it lasts?

• TrafficBusy driveways with daily vehicle use wear faster than a quiet patio

• ExposureFull sun, heavy rain and shaded, damp spots all take their toll

• PreparationSealant applied to clean, completely dry paving bonds best

• MaintenanceRegular cleaning keeps the surface performing for longer

What block paving sealant protects against

• Oil stains: Resiblock Superior is the only block paving sealant in Europe with a No Oil Stains Guarantee.
• Fluid damage: spilt drinks, food and overflowing drains can’t soak into the blocks.
• Weather and UV: the protective layer stops rain saturating the blocks and prevents colour fading in strong sun.
• Weeds and sand loss: bound jointing sand stays in place, even when pressure washed, and weeds can’t take root.
• De-icing salts and chemicals: the sealant is unaffected by de-icing salts and resists many commercial chemicals.

How to make your sealant last longer

A few simple habits will help your sealant reach its full lifespan:

• Pressure wash seasonally: sealing stops weeds growing in the joints, and any algae or moss that settles on the surface can be removed easily with a regular wash.
• Deal with spills quickly: remove oil spills promptly with detergent or Resiblock Oil Remover.
• Tackle green growth early: treat any algae with Resiblock Algae, Mould and Lichen Remover before it builds up.

Signs it’s time to reseal

After a few years, look out for colour starting to fade, weeds reappearing between the blocks or jointing sand washing out. When it’s time, clean the paving thoroughly and reapply. If the paving was previously sealed with another brand, strip it first with Resiblock Paving Sealer Remover to avoid compatibility issues.
