How to Seal Block Paving for Long-Lasting Protection and a Great Finish

Block paving looks smart and lasts well, but it needs protection to stay clean, strong, and attractive over time. Both concrete and clay blocks soak up water and collect dirt, making them prone to stains, moss, and weed growth.

Applying a quality sealer protects the surface and keeps your paving looking newer for longer.

Why Should You Seal Block Paving?

Using a block paving sealer gives you long-term benefits:

✔ Stops water, oil, and dirt from soaking in and causing permanent stains
✔ Helps block moss, weeds, and algae from growing in the joints
✔ Enhances the surface, keeping colours rich and bold
✔ Protects against frost, sun, and general weather damage
✔ Locks jointing sand in place, reducing movement and washout

Without sealing, paving may fade, stain, or shift—especially on busy driveways or paths.

Is It Easy to Seal Block Paving?

Yes! Sealing is simple enough for both pros and DIYers.

• Just follow these steps:
• Clean and dry the surface thoroughly.
• Apply the sealer evenly using a roller, sprayer, or wide brush.
• Let it dry fully before walking or driving over the area.

A clean, dry surface helps the sealer bond properly and gives the best long-term results.

Which Sealer Should You Choose?

Choose from two main types: solvent-based and water-based.
Each offers different benefits depending on the surface type and look you want.

Solvent-Based Sealers
✔ Soak deep into the surface for strong, lasting protection
✔ Great for driveways and busy outdoor areas
✔ Boost colour and help the blocks resist wear

Water-Based Sealers
✔ Better for the environment and safer to use
✔ Work well but often need more product for strong results
✔ Ideal when you want less solvent smell or faster cleanup

Sealer Finish Options
🔹 Invisible – Keeps the natural look while still protecting the surface
🔹 Matt – Soft finish with less shine, but doesn’t last as long as other options
🔹 Satin – Adds a slight sheen and offers a good mix of looks and durability
🔹 Gloss – Creates a bold, wet-look shine and gives the longest protection

Matt finishes in solvent-based sealers use less resin, so they may wear faster than satin or gloss.

Water-based sealers usually need more coats to properly bond the jointing sand and create a strong surface.

Why Use a High-Quality Sealer?

Not all sealers give the same results. Lower-grade or all-purpose sealers might cause patchy finishes or wear down fast.

Our recommended professional-grade sealers:

✅ Protect your paving without damaging the surface
✅ Last longer, especially in busy or exposed areas
✅ Apply easily and leave a clean, even finish

Sealing your block paving protects your investment. It blocks stains, slows wear, and keeps the surface looking sharp for years.

Choose the right sealer type and finish, apply it carefully, and you’ll reduce maintenance while keeping your driveway or patio looking brand new.
