Sealing

Concrete, brick, block paving and slabs sealed to lock in the clean finish and guard against future stains — done after the surface has already been properly cleaned, never over dirt.

How it's done

How proper sealing works

Same job, every time, done in order — because skipping a step is how sealing goes wrong.

Start with a clean, dry surface

Sealer trapped over dirt, moss or algae just locks the mess in under a glossy coat — it doesn't fix it. The surface needs to already be properly cleaned and fully dry before sealing starts. That's a separate job and isn't included in the sealing price — it has to happen first, whether booked as part of the same visit or done beforehand.

Check the surface over

Cracks, damaged edges, and on block paving, any joints that have lost their sand. Loose or missing joint sand needs topping up before sealing, because the sealer will bind whatever's sitting in those gaps in place. Seal over empty or badly packed joints and you're locking in a problem, not fixing one.

Pick the right sealer

Matte or a wet-look gloss finish, and a product suited to the surface — concrete, brick, block paving or slabs don't all take sealer the same way. A test patch is worth doing first, especially on a colour-sensitive or porous surface, to confirm the finish looks right before committing to the whole area.

Apply in thin, even coats — normally two

A heavy coat pools, dries unevenly, and leaves patchy results once cured. Thin and even, with the first coat properly dry before the second goes on, gives a consistent finish. Sprayed or rolled on, kept off adjoining areas that aren't being sealed.

Let it cure properly

Surfaces can usually take foot traffic within a few hours, but vehicles need longer — typically 24 to 48 hours. Driving or parking on it too soon can mark or lift the coating before it's hardened.

What it buys you

Done right, sealing locks in the cleaned finish, adds protection against oil stains, weather and UV fading, and slows down how fast moss and algae take hold again. It's not permanent — most sealed surfaces need reapplying every few years depending on traffic and weather exposure — but it buys real time between clean-ups.

Got a tarmac driveway?

This service covers concrete, brick, block paving and slabs — not tarmac. Tarmac needs a different process entirely (a bitumen-based restorer that replenishes the resin the surface has lost, not just a coat sitting on top), so it's handled under Tarmac Sealcoating / Restoration instead, at its own rate.
