What changes the cost of acrylic render?
An acrylic render quote depends on what has to go under the thin coloured finish, such as a base coat, mesh and primer, plus the wall area, the grain and colour, access and the weather window. This guide does not print a price per square metre and sets out what to compare.
Last reviewed:What is acrylic render?
Acrylic render is a thin, coloured top coat that uses an acrylic resin as its binder. It usually comes ready-mixed in tubs, so it is not mixed from sand and cement on site. A renderer trowels it on in a thin layer and works it with a float to give a fine, even grain.
On its own, acrylic is only the finish. It forms the last layer of a render system: a base coat on the wall, often with a reinforcing mesh pressed in, then a primer, then the acrylic. The same kind of finish is also used on many external wall insulation systems, over the insulation boards.
People choose it for its clean, even colour, because it does not normally need painting, and because the resin gives the finish some flexibility.
This guide sets out what a renderer prices when quoting for acrylic render. It does not print a price per square metre or a house total, because those depend on the build-up your walls need.

What moves an acrylic render quote?
Because the acrylic coat is thin, most of the difference between quotes sits in what goes underneath it and in getting to the wall.
| What moves the quote | What to look for in writing | Why quotes drift apart |
|---|---|---|
| Base coat | Whether a new base coat goes on, and its thickness | Going over sound render is different from starting on bare block |
| Reinforcing mesh | Mesh across the whole wall, or only at corners and openings | Full mesh adds material and labour but resists cracking |
| Primer | The primer the system calls for, matched to the finish | Skipping primer can leave patchy colour or poor grip |
| Grain size | The texture, from fine to coarse | Different grains use different amounts of material |
| Colour | A standard shade or a mixed colour | Some colours cost more to supply |
| Beads | Corner, stop, base and window beads in the system | Edges without beads chip and crack |
| Preparation | Cleaning, removing loose render, repairing cracks | A poor wall takes days before any finish goes on |
| Access | Scaffold or tower, and for how long | The finish needs steady work across each wall |
| Weather | Allowance for dry, mild days and covers | Rain or frost can spoil a fresh finish |
| Waste and making good | Removing old render and refixing pipes, cables and lights | Left out of one quote, included in another |
Ask every renderer to price the same walls with the same system. If one names a manufacturer's system and another just says "acrylic", ask the second to name the products.
Why does the system matter?
Acrylic renders are usually sold as part of a manufacturer's system, where the base coat, mesh, primer and finish are designed to work together. Using parts from the same system, as the maker specifies, matters for how well the finish bonds, how it copes with movement and how it weathers.
When you compare quotes, ask:
- Which manufacturer's system is being used, and which products in it?
- Is the build-up the one the maker specifies for your type of wall?
- Will the renderer follow the maker's instructions for drying times between coats?
- Is any maker's or installer's warranty offered, and what does it need from you?
Some renderers offer other thin-coat finishes, such as silicone render, which is designed to repel water, or silicate render, which is mineral-based. These sit in the same kind of system and can suit some walls better. A renderer should be able to explain why they recommend one over another for your house.
For a thicker, one-coat through-coloured system, see what changes the cost of monocouche render. For a traditional site-mixed render, see what changes the cost of cement render.
What does the wall need before the finish goes on?
An acrylic finish is only as good as the wall under it. Expect the renderer to look for:
- Loose or hollow render, which needs cutting out before a new base coat.
- Cracks, which need repairing and sometimes meshing across.
- Damp, from leaking gutters, failed sills or soil piled against the wall.
- Dirt, algae and old paint, which need removing so the new layers can grip.
- Movement, such as a crack that runs through the masonry or keeps reopening, which may need a builder before any render work.
On an older solid wall, ask whether a breathable system would suit it better. Acrylic finishes are less permeable than lime, and a wall that needs to dry outwards can trap moisture behind a tight finish.
The quote should say which repairs are included and how extra repairs will be priced if more damage shows up once old render comes off.
Why does weather affect the price?
Thin-coat finishes need suitable conditions to cure. Rain on a fresh coat can wash it out, frost can spoil it, and hot sun or strong wind can dry it too fast and leave marks. The maker's instructions set the temperature and weather limits.
This affects quotes in a few ways:
- A renderer may plan the work for the warmer, drier months.
- Scaffold may need covers or sheeting, which adds cost.
- Delays for weather can mean the scaffold stays up longer.
Ask how the renderer plans around the weather and whether extra scaffold time is charged.
What safety and permission points apply?
Access. Rendering the walls of a house is normally done from scaffold. HSE says work at height covers any place where, without precautions, a person could fall a distance liable to cause injury, including work above ground level [S4]. Ask who arranges the scaffold and whether it is in the price. HSE explains more on its work at height questions page.

Planning. The Planning Portal says replacing render with render of a similar appearance does not need planning permission, but changing the type or colour of the render is likely to change the external appearance, and then planning permission will be required [S1]. It also says that in a conservation area, a national park, an area of outstanding natural beauty or the Broads, you need planning permission before cladding the outside of the house with render [S2]. Turning bare brick into a coloured rendered finish is a visible change, so check with the council.
Building regulations. The Planning Portal says that where 25 per cent or more of an external wall is re-rendered or re-clad, the regulations would normally apply and the thermal insulation would normally have to be improved [S5]. That is one reason some acrylic jobs grow into an insulated render system. GOV.UK explains when you need building regulations approval.
This guide does not give an application method. Hire a renderer who works to the system maker's instructions.
How do you compare acrylic render quotes?
Citizens Advice says a quote should give a fixed total price rather than a daily rate, a breakdown of the work and materials, how long the price is valid and whether it includes VAT [S6]. It suggests getting written quotes from at least three traders [S6].
Questions to ask each renderer:
- Which system, and which base coat, mesh, primer and finish?
- Which walls are included, and what area?
- What preparation and repairs are in the price?
- Which colour and grain, and can I see a sample?
- Is the scaffold included, and for how long?
- What happens if the weather holds up the work?
- How should the finish be cleaned and looked after?
- Does the price include VAT?
On VAT, a business must register when its taxable turnover for the last 12 months goes over £90,000 [S3]. Some renderers will add VAT and some will not, so ask.

Questions about acrylic render costs
How much does acrylic render cost?
This guide does not print a figure. The build-up under the finish, the area, the colour, the access and how much preparation the wall needs all change the price. Ask for itemised quotes that name the system, the coats and the scaffold for the same walls.
What is acrylic render?
It is a thin-coat render that uses an acrylic resin binder, usually sold ready-mixed in tubs and already coloured. It goes on as the top coat of a render system, over a base coat and primer, and is finished with a float to give a fine texture.
Can acrylic render go straight onto brick?
Usually not on its own. Acrylic is a thin finishing coat, so most systems put a base coat, often with a reinforcing mesh, on the brick or block first, then a primer, then the acrylic. Ask the renderer which build-up the system maker specifies for your wall.
Does acrylic render need painting?
Usually not. It is normally through-coloured, so the colour is in the finish itself. Some people paint it later to change the colour. Ask the renderer which colours the system offers and how the finish should be cleaned.
Is acrylic render suitable for an old house?
Not always. Acrylic finishes are less breathable than lime, and an older solid wall may need a finish that lets moisture out. Ask whether a silicone, silicate or lime-based system would suit your wall better, and why.
Do I need planning permission for acrylic render?
It depends on the change. The Planning Portal says changing the type or colour of render is likely to change the external appearance, and then planning permission will be required. In a conservation area, national park or AONB, permission is needed before cladding with render.
Will the quote include VAT?
Not always. A business must register for VAT when its taxable turnover for the last 12 months goes over £90,000. Ask each renderer whether their figure includes VAT.
Does QuoteZila check the renderers who quote?
No. We don't check insurance, qualifications or registrations, so please check these yourself before you hire. You can report a quote or a business from your job page.
This page is general information, not professional or legal advice. QuoteZila does not check Gas Safe, WaterSafe, NFRC, NICEIC or other registrations against the register on your behalf: look them up yourself.
