Through-colour render has its pigment mixed through the finish coat, so the colour is the render itself and it doesn’t need routine painting; painted render is a plain render, usually sand and cement, that gets its colour from masonry paint applied afterwards. Through-coloured systems such as silicone, acrylic, monocouche and mineral renders cost more to install but avoid a repainting cycle and keep their colour well. Painted render is cheaper upfront and lets you change colour whenever you redecorate, but it needs repainting periodically, usually with access equipment each time. For most homeowners planning to stay put, through-colour works out the better long-term value; painted render still makes sense on a tight budget, for small or easily reached walls, and on traditional lime-finished houses.
- Through-colour render carries its pigment in the finish itself; painted render relies on masonry paint.
- Through-coloured systems typically cost indicative £55–£100/m²; sand and cement £35–£60/m², plus painting if not included.
- Painted render needs repainting periodically; through-colour needs only occasional cleaning.
- Painted walls are easy to recolour; through-colour is effectively permanent until recoated or re-rendered.
- Repairs disappear under a fresh coat of paint, but can show on weathered through-coloured render.
- On traditional lime-built houses, lime with limewash is often the right choice regardless of convenience.
What through-coloured and painted render actually mean
Through-coloured (sometimes written “through-colour” or “self-coloured”) means the pigment is blended into the render material before it goes on the wall. When it’s applied, the colour isn’t a layer on the surface — it runs right through the finish coat. Scratch it and you see the same colour underneath. There’s no paint to flake or peel, and no repainting cycle to plan for.
Painted render is a plain render, typically grey or off-white, that is left to cure and then decorated with masonry paint. The render does the weatherproofing; the paint provides the colour and some surface protection. Over time the paint fades, chalks and eventually needs renewing, while the render underneath carries on.
That’s the whole distinction, but it has knock-on effects for cost, maintenance, repairs and flexibility that matter much more than they first appear. Through-coloured renders are now widely used on new and re-rendered homes, although painted render still has a clear place.
Which renders are through-coloured and which are painted
Usually through-coloured:
Silicone — a thin-coat system with a coloured silicone-resin finish over a meshed base coat. Highly water-repellent and slow to pick up dirt. Branded systems such as K-Rend fall into this group. See our silicone render page.
Acrylic — a thin-coat system with a coloured acrylic finish; flexible and available in a wide colour range.
Monocouche — a cement-based render with the colour mixed through, applied in one thick coat and scraped back. See our monocouche render page.
Mineral and silicate — often supplied through-coloured, and also compatible with breathable silicate paints where a painted finish is wanted.
Usually painted:
Sand and cement — the traditional render on many UK homes, usually finished with masonry paint. See our sand and cement render page.
Tyrolean — a textured finish usually applied with a hand-operated machine, that is commonly painted, although coloured mixes are available.
Lime — often finished with limewash, a traditional breathable coating renewed periodically, or left in its natural colour. Limewash isn’t modern paint, but it behaves like a painted finish in that it needs renewing.

Upfront cost
On day one, painted render is the cheaper option. As indicative installed prices per square metre, indicative sand and cement typically runs at around £35–£60 and Tyrolean £50–£80. Through-coloured systems sit higher: monocouche around £55–£90, acrylic £60–£90, silicone £65–£95 and mineral £65–£100. Lime, which is often limewashed, is typically £70–£125 because it’s slower, more skilled work.
Check whether a painted quote includes the first coats of masonry paint; if not, that’s materials and labour on top. And on a whole house, much of the cost — scaffolding, stripping old render, preparation, beads and making good — is the same whichever finish you choose. That means the percentage gap between a painted and a through-coloured job is usually smaller on the final quote than the per-square-metre figures suggest.
Our render cost index sets out current indicative prices by render type in one place, and our house rendering cost guide turns them into whole-house budgets.
Repainting: the cost that doesn’t appear on the quote
The biggest practical difference between the two is what happens after the scaffold comes down. A through-coloured render doesn’t need painting at any point in its life. A painted render does — periodically, for as long as you own the house.
How often depends on the paint, the colour, the exposure and how fussy you are about appearance. Sunny and weather-facing elevations fade and chalk faster; sheltered walls last longer. Dark colours tend to show fading sooner than pale ones. Many homeowners find the front of the house needs attention before the sides and back.
Each repaint is a project in its own right: washing down, treating any algae, filling hairline cracks, and two coats of masonry paint. On a bungalow or a low extension that may be a ladder job. On a two- or three-storey house, it usually means scaffolding or a tower again. It’s worth asking a decorator or scaffolder for a quote for your own house if you want a real number to compare, because it varies so much from property to property.
None of this makes painted render a bad choice. It just means the true cost is the install price plus a recurring decorating bill, while through-colour is closer to a one-off cost.
Colour consistency and how repairs look
Here painted render has a genuine advantage. When a painted wall is repaired — a crack cut out, a hollow patch replaced, a new fixing made good — the repair is simply painted over at the next redecoration and disappears.
On through-coloured render, the repair is in the colour material itself. New material from a new batch, on a wall that has weathered for years, rarely matches perfectly. A skilled renderer can get very close by matching the colour reference, finishing the repair to a natural break such as a bead line or corner, or recoating the whole elevation. But on a large, plain, sunlit wall a patch can remain faintly visible, especially in raking light.
The same applies during installation. Through-coloured material should come from consistent batches and be applied wet-edge to natural breaks, so that each elevation dries evenly. Poor sequencing can leave visible lap lines or shade differences that can’t simply be painted out. It’s a good question to ask any renderer: how will you keep the colour even across the whole house?
Fading and weathering over time
All colours change outdoors. The question is how and how fast.
Painted render fades as UV breaks down the paint film, often first on the south and west elevations. The surface can become chalky — rub it and colour comes off on your hand — and eventually the paint flakes, particularly where moisture is coming from behind. The fix is to repaint, which resets the colour completely.
Through-coloured render fades much more gradually, because the pigment runs through the finish rather than sitting in a thin film. Modern silicone and acrylic finishes are formulated to hold their colour well, and paler shades hold up best. Deep, saturated colours on sunny walls can soften over time on any system. What many people take for fading is often a film of dirt or algae on the surface, which can be cleaned off to bring the colour back.
In short: painted render fades and is renewed in cycles; through-coloured render changes slowly and is cleaned rather than repainted. Our guide to do render colours fade explains what’s fading and what’s just dirt, and our guide to the best render colours covers shades that weather well.
Cleaning and algae
Both types of render can pick up dirt and green algae, especially on north-facing, shaded or tree-lined walls. How you deal with it differs.
On a painted wall, cleaning is usually part of the repainting job: the wall is washed down and treated with a biocide, then repainted, and the fresh paint covers any staining that won’t shift. Between repaints, a gentle clean can freshen it up.
On a through-coloured wall, cleaning is the maintenance. Silicone finishes are highly water-repellent and shed a lot of dirt with the rain, so they tend to stay cleaner for longer; monocouche and some acrylics can hold dirt more readily. When cleaning is needed, a suitable render cleaner or biocide applied at low pressure is the norm. Aggressive pressure washing can damage the surface and should be avoided. Our guide on algae on render explains causes and treatment.
Either way, cleaning a through-coloured wall is a smaller, cheaper job than repainting a painted one.
Freedom to change colour
If you like to change the look of your house, painted render is the more forgiving choice. Every redecoration is a chance to go lighter, darker, warmer or cooler, and getting it slightly wrong is fixed next time round.
A through-coloured render is, for practical purposes, permanent. Changing the colour means applying a new through-coloured finish over the existing system (where it’s sound and the manufacturer allows it) or, in some cases, a suitable paint designed for that render — though painting over a through-coloured finish brings back the repainting cycle you chose it to avoid. Either way, it’s a significant job rather than a weekend’s decorating.
That’s why sampling matters so much more with through-colour. View large samples on your own wall, in different light, before committing. Our silicone render colours guide covers how through-coloured shades look in practice.
Whichever finish you choose, a significant change of colour can alter a house’s appearance enough to need planning permission in some situations, particularly in conservation areas and other protected areas. Check with your local planning authority before committing to a dramatic change.
Paint, breathability and older walls
The paint on a painted render isn’t only cosmetic. On older solid walls, the wrong paint can cause real problems. Non-breathable coatings can trap moisture in the render and the wall behind, leading to blistering, flaking and damp. That’s why breathable masonry paints, silicate paints on mineral renders and limewash on lime are the usual choices for painted finishes on traditional buildings.
Through-coloured silicone and mineral finishes are designed to let water vapour out while keeping rain off, so breathability is built in. Monocouche is moderately breathable. Acrylic finishes are generally less vapour-open than silicone or mineral, which matters more on older solid walls than on modern cavity construction.
On a traditional lime-built house, the right answer is often neither a modern through-coloured system nor a modern masonry paint, but lime render finished with limewash. It needs renewing periodically, like paint, but it suits the wall and helps the render and masonry last.
How each copes with cracks
Whether a render cracks depends far more on the render type, the wall and the installation than on how it’s coloured. But colouring does affect how cracks look and how they’re dealt with.
On painted sand and cement, fine hairline crazing is common, and a good flexible masonry paint can bridge many hairline cracks at each redecoration, keeping water out and hiding them from view.
On through-coloured renders, there’s no paint film to bridge cracks. Flexible thin-coat systems such as silicone and acrylic, applied over a fully meshed base coat, resist cracking well. Monocouche, being a thicker cement-based coat, can show fine hairline crazing, and on a through-coloured surface those cracks stay visible unless the area is repaired or recoated.
For a full head-to-head of sand and cement against silicone, our cement vs silicone render guide goes into cracking, water and maintenance in depth.

Put the pieces together over the years you expect to live in the house and the picture usually shifts.
A painted render starts cheaper. Then, every few years, it costs something again: paint, labour and, on most two-storey houses, access equipment. Over a couple of decades those repaints add up, and on a taller or awkward house they can close much of the original price gap. A through-coloured render starts dearer, then mostly sits there, needing an occasional clean.
Exactly where the lines cross depends on your house. The bigger, taller and harder to reach the walls, the faster through-colour pays back, because repainting is expensive when every job needs scaffolding. On a single-storey extension or a bungalow you can reach from a ladder, repainting is cheaper and the case for painted render is stronger.
There are non-financial costs too. Repainting means disruption, choosing a decorator and living with tired-looking walls in the years before it’s done. Some owners don’t mind that; others value never having to think about it.
How each one looks
Both can look excellent. Painted render gives a very uniform, even colour straight after decoration, and suits traditional houses and period streets where a painted finish is the local character. Over time, though, a painted wall gradually looks tired until it’s redecorated.
Through-coloured render has a slightly different quality. Thin-coat silicone and acrylic finishes have a fine, even texture with a crisp, contemporary look. Scraped monocouche has a soft, slightly textured surface. Because the colour is in the material, the finish can show a little natural variation, which many people find softer and more natural than a flat painted surface.
Texture matters as much as colour type. The same shade can read quite differently on a smooth, scraped or dashed finish, so look at real examples in the finish you’re considering.
If your house already has painted render
If you have a painted render that’s sound, you have three broad options.
Keep repainting. If the render is bonded and dry and you’re happy with the look, carrying on with periodic redecoration is often the cheapest route in the short to medium term.
Overcoat with a through-coloured system. Where the existing render is sound, some through-coloured systems can be applied over it, typically after removing loose paint, applying a base coat with mesh and then a coloured finish. This ends the repainting cycle without stripping the wall. Whether it’s suitable depends on the condition of the existing render and paint, so it needs a proper survey.
Strip and re-render. If the render is cracked, hollow or the wrong type for the wall, overcoating just hides the problem. Taking it back to the masonry and starting again with the right system is the long-term fix.
Some homeowners also consider wall coatings on sound render as an alternative to repainting; it’s worth comparing any option on what it involves for your walls.
The verdict: which suits which situation
You’re re-rendering a two-storey house and plan to stay. Through-colour is usually the better value. Avoiding repeated scaffolding for repainting is the deciding factor. A silicone render system is a popular choice for low maintenance.
You’re on a tight budget now. Painted sand and cement keeps the upfront cost down, and you can always overcoat with a through-coloured finish later if the render stays sound.
It’s a single-storey extension or bungalow. Painted render is easy to maintain from a ladder, so its cost advantage holds up better. Matching the main house may decide it.
You like to change colour. Painted render gives you that freedom.
It’s a traditional solid-walled or period house. Breathability comes first. Lime with limewash, or a mineral render, is often more appropriate than either modern option.
It’s a new build or new blockwork. Through-coloured monocouche or thin-coat systems are the norm and give a finished look without decorating.
You want a dark or bold colour. A through-coloured system formulated for dark shades is usually more reliable than dark masonry paint on a rigid render.
Questions to ask your renderer
Is my wall suitable for a through-coloured system, or would you recommend a painted or lime finish, and why? Which specific system would you use, and what is its colour range? How will you keep the colour consistent across all the elevations? If I need a repair in future, how well can it be colour-matched? What cleaning will it need, and what methods should I avoid? If my existing render is painted, could it be overcoated, or does it need stripping? What guarantee comes with the finish, and does it require particular maintenance? Asking the same questions of each renderer makes their quotes much easier to compare.
When neither option is quite right
Sometimes the colour question is a distraction from a bigger one. If your existing render is cracked, hollow or letting water in, choosing between through-colour and paint matters far less than fixing the cause and getting the right render on the wall. On some traditional buildings, especially listed ones, the finish may be dictated by what the building needs and what the conservation officer will accept. And on a wall that’s sound and you’re happy with, repainting may simply be the sensible, economical answer for now.
