Imprinted concrete cleaning & resealing
In short
Stripping the old, worn sealer off a pattern imprinted drive, cleaning it back properly and recoating — which restores the colour and the stain resistance. It is a maintenance job the surface genuinely needs every three to five years, and it is far cheaper than replacing a drive that has been left too long.

Signs you need this
- The colour looking flat, chalky or faded compared with when it was new
- Rain soaking in and darkening the surface rather than beading
- Visible wheel tracks where the sealer has worn through
- Oil and leaf marks staining rather than washing off
- Old sealer flaking, peeling or looking milky in places
- Moss and algae establishing in the pattern texture
An imprinted concrete drive is a coloured, textured slab with a sealer on top, and that sealer is doing more work than most owners realise. It saturates and deepens the colour, it resists oil and staining, it protects the surface from frost damage, and it is the reason a new imprinted drive looks so much richer than the same slab does dry. It is also a consumable: it wears, it dulls, and it eventually fails.
The usual cycle is three to five years, and the signs are consistent. The colour looks flat and chalky rather than deep. Water soaks in and darkens the surface instead of beading on it. The wheel tracks look different to the rest. Oil marks now stain rather than sitting on the surface. And in bad cases the old sealer starts flaking or going milky, particularly where water has got underneath it.
The job is mostly preparation. The old sealer has to come off, not be coated over — a new sealer applied over a worn, contaminated or flaking one bonds to the failing layer rather than to the concrete, and it will lift in sheets. That means a chemical strip or a controlled pressure clean, removing moss and algae, treating oil stains, and then letting the slab dry thoroughly. Sealing a damp slab traps moisture and turns it milky, which is the commonest DIY failure.
There is a decision to make about the finish. A high-gloss sealer gives the deepest colour and the wet look people often want; it also shows wear more quickly and can be slippery when wet, particularly on a falling drive. A satin or matt sealer is less dramatic, ages more gracefully and is less slick. An anti-slip additive can be mixed into either and is worth specifying on any drive with a slope or a shaded, damp aspect.
Colour can be adjusted at the same time, within limits. A drive that has faded unevenly can be re-tinted with a coloured sealer or a colour restorer to even it up, and a tired colour scheme can be shifted somewhat. What cannot be done is a wholesale change — the surface hardener is in the concrete itself, and a sealer sits on top of it rather than replacing it.
This is also the moment cracks and joints get dealt with, because they are visible and accessible with the drive stripped. Joints that have filled with debris get cleaned out and resealed. Dormant cracks get routed and filled before the sealer goes on, so the repair is under the coating rather than sitting on it. Doing them after the reseal means damaging a finish you have just paid for.
What the job covers
- An assessment of whether stripping or a light clean and recoat is needed
- Old sealer removed rather than coated over
- Moss, algae and organic growth treated and removed
- Oil and stain treatment before sealing
- Joints cleaned out and resealed
- Dormant cracks routed and filled before the coating goes on
- Slab dried thoroughly before any sealer is applied
- Sealer applied in coats, with an anti-slip additive where appropriate
What it costs
We don't publish a price for this yet, because a number pulled out of the air is worse than no number at all — your contractor has to honour it. On driveways it would also be close to meaningless: the groundworks are usually the biggest single factor, and how deep the dig has to go varies enormously house to house. You'll get a firm price for your actual job when they ring you back, before any work starts. The quote itself is free and there's no obligation either way.
Common questions
How often should imprinted concrete be resealed?
Every three to five years for most drives, sooner on one that gets heavy use or full sun. The practical test is whether water still beads on the surface. Once it soaks in and darkens the concrete, the sealer has gone and the surface is no longer protected from staining or frost.
Can I just put a new coat on top of the old one?
Only if the existing sealer is sound and simply thin, which is the case if you keep on top of it. Once the old coating is worn through in places, flaking or contaminated, a new coat bonds to a failing layer and lifts. Then it has to be stripped properly, which is more work than if it had been recoated on time.
My drive went milky after it was sealed. What happened?
Moisture trapped under the sealer, almost always because the slab was not fully dry when it was coated. It can also happen if sealer is applied too thickly or in the wrong temperature. It usually has to be stripped and redone. It is the single commonest DIY sealing failure and the reason the drying time matters more than the sealing time.
Can resealing change the colour?
It can even out fading and shift the tone somewhat, using a coloured sealer or a colour restorer. It cannot change the colour wholesale, because the colour lives in the surface hardener within the concrete itself. If a complete change is what you want, an overlay in another material is the realistic route.
