Tarmac Sealcoating & Restoration
Faded, worn tarmac brought back with a proper sealcoat — cracks repaired, surface sealed, and water and UV damage locked out, not just sitting on top of the surface.

How tarmac sealcoating & restoration is done properly
Tarmac doesn't fail overnight. It fades, it cracks, water gets into it, and before long a driveway looks ten years older than it is. Sealcoating stops that, but only if the surface is properly prepped first. Here's what a proper job actually involves.
Inspect the surface
A proper job starts with checking the tarmac for cracks, potholes, oil staining, low spots where water pools, and general wear. That's what decides whether it's a straightforward clean-and-seal or something needing repair work first. Sealing over a problem doesn't fix it — it just traps it under a fresh coat.
Clean the surface
Sealant won't bond to dirt, moss or oil, so the surface has to be properly cleaned before any sealcoat goes on, usually with a power wash. Skipping this step is one of the most common reasons a sealcoat job fails early.
Repair cracks and low spots
Cracks and low spots get filled and levelled before sealing. Sealcoat is a protective layer, not a patching compound — it follows the shape of whatever's underneath, cracks included, if this step gets skipped.
Let it dry properly
Sealcoat needs a dry surface to bond to. Depending on the weather, that means allowing proper drying time after cleaning before any sealant goes down. A coat applied to a damp surface won't cure right and won't last.
Apply the sealcoat
An even coat of bitumen-based sealant goes on across the full surface, applied in sections so it's consistent rather than patchy. This is what actually protects the tarmac going forward — it locks out water, blocks UV fading, and brings back that deep black, freshly-laid look.
Second coat where needed
Heavily worn or older surfaces often need a second pass to get proper coverage and colour depth. Whether that's needed is usually clear once the first coat is down.
Allow proper cure time
Same day for foot traffic. 48 hours before vehicles. Curing time matters — using the surface too soon undoes the work.
A tarmac surface that's sealed against water and UV damage, free of the cracks and staining it had going in, and back to looking like new.
