Coloured Resin Coating or Clear Sealer: Which Suits Your Surface?
Choose a clear sealer if you like the colour your concrete already has and only want to protect it or add sheen; choose a coloured resin coating if the colour has faded, gone patchy or been spoilt by repairs. A clear product preserves what is there, good or bad, while a coloured one replaces it with a new, even tone.
Send us a photo and the m²What is the basic difference?
A clear sealer is transparent: whatever colour and marks your concrete has will still be visible, just with a different sheen and some protection. A coloured resin coating contains pigment, so it covers the existing surface with a uniform new colour.
| Clear sealer | Coloured resin coating | |
|---|---|---|
| Effect on colour | Keeps the existing colour, often deepens it slightly | Replaces it with a new, even colour |
| Hides repairs and patches | No | Yes, under the new colour |
| Hides fading | Partly, by darkening | Yes |
| Protective film | Depends on product type | Yes, as stated on the data sheet |
| Our standard service | No | Yes, in two coats |
When is a clear sealer the right choice?
A clear sealer makes sense when the surface still looks good after cleaning: the colour is even, the pattern is crisp and there are no obvious repairs. It adds a finish and some protection without changing the character of the concrete.
It is not our standard service, and we say so openly. If your surface is in that condition, a clear product from a specialist may suit you better than our coloured system.
When is a coloured resin coating the better option?
A coloured coating is better whenever the colour itself is the problem. Faded imprinted concrete, a driveway patched in three different greys, stains that will not come out completely and a pattern that has lost its contrast all call for pigment, not transparency.
The photo makes the point: on the untreated half, a clear sealer would simply have glossed over the faded tone, while the coated half has a completely new, even colour. Our coloured resin coating page explains how the two-coat system is built.
Which offers better protection?
It depends on the specific products rather than on whether they are clear or coloured. Some clear sealers form a film, others penetrate the concrete; coloured floor coatings form a film that carries the pigment.
The resistance of any product to water, oil, sun and wear is stated on its data sheet, and that is where the comparison should be made. The protective side of our system is set out on the concrete sealing page.
What about imprinted concrete that was sealed before?
Most imprinted concrete was sealed with a clear product when it was laid, so it is easy to assume resealing it the same way is the obvious next step. If the original colour has held up, that may be true.
If the colour has faded or the old sealer has turned white and patchy, another clear coat will lock that look in. Removing failing sealer and recolouring usually gives a much stronger result, as the Marbella driveway on our projects page shows.
Which is better for a pool surround or terrace?
On terraces and pool surrounds, grip and comfort underfoot matter as much as appearance. Both clear and coloured products vary in how smooth they feel when wet, and slip resistance is given on the data sheet (to be verified for each product).
If the terrace colour is tired, a coloured coating with a suitable finish is usually what transforms the space. Our patio and terrace painting page covers how we approach living areas, and our colour guide helps with the choice of shade.
Can you switch from one to the other later?
Going from clear to coloured is common: when a sealed surface eventually fades, it can be prepared and recoloured, provided any failing sealer is removed and the new product is compatible with what remains.
Going from coloured back to the bare look is much harder, because the pigment has to come off completely. That is worth knowing before you decide. If you think you may want the natural concrete look again one day, start with cleaning and a careful assessment rather than colour, and send us photos so we can give you a straight opinion.
Frequently asked questions
Can a clear sealer restore faded colour?
Only partly. Many clear sealers darken the surface slightly when applied, which can make faded concrete look a little richer, but they do not add pigment. Uneven fading, patches and repairs remain visible under a clear finish, which is why coloured coatings exist.
Do you apply clear sealers?
Clear-only sealing is not part of our standard service. Our system is a coloured synthetic resin coating in two coats, which also acts as a protective layer. If your surface would be better served by a clear product, we will tell you honestly rather than sell you something unsuitable.
Is a coloured coating more durable than a clear sealer?
Durability depends on the specific product, not on whether it is clear or coloured. Each product's data sheet states its resistance to traffic, water, sun and chemicals, and that is the only fair basis for comparing them. Preparation matters just as much as product choice.
Can a coloured coating go over an old clear sealer?
Sometimes, if the old sealer is sound, well bonded and compatible with the new product according to its data sheet. If the sealer is flaking, white or powdery, it has to be removed first, or the new coating will come away with it.
Will a coloured coating hide the pattern of imprinted concrete?
No. The coating follows the texture of the surface, so the stone, brick or cobble pattern stays visible. In fact, a fresh, even colour usually makes the pattern stand out more clearly than the faded original did. Edges and joints of the pattern read more sharply too.
Which option is better for a rental villa?
If the surface colour is still good, a clear finish keeps it looking fresh. If it has faded or is patchy, a coloured coating gives the stronger first impression in photos and on arrival. A coated surface is also straightforward for cleaners to sweep and rinse.
Can I have a coloured coating and then a clear top coat?
Some systems allow a clear top coat over a coloured base, while others are designed to be used on their own. Compatibility is set out on the data sheets of the products involved. Our standard service is two coats of coloured synthetic resin paint.
Does a clear sealer need less maintenance?
Not necessarily. Both clear and coloured products need regular sweeping and gentle washing, and both eventually need renewing at intervals given on their data sheets. Clear sealers that turn white or cloudy can be particularly awkward to put right. Regular care keeps either looking better.
How do I know which one my concrete needs?
Clean a small area and look at it in daylight. If the cleaned concrete looks even and attractive, a clear product may be enough. If it is still faded, patchy or marked, a coloured coating is the better route. Photos sent to us after cleaning help us advise.
Is a coloured coating suitable for block paving?
Yes, concrete block paving can be recoloured with a coloured coating once the blocks are firm and the joints are cleaned and repaired. Clear sealers are also used on paving, but they cannot hide faded or mismatched blocks. Our paver painting page explains the process.
