Radiators might not be the most exciting feature in a room, but a quick flick of paint can completely transform them from eyesore to eye-catching. If you’re wondering whether you can paint your radiator and how to do it well, we’ve got you covered with our simple, expert-backed tips plus advice to help you choose the right paint for lasting results.
Can You Really Paint a Radiator?
Yes, you absolutely can. In fact, painting your radiator is one of the easiest ways to make it blend in beautifully or stand out in style. Whether you want it to match your wall colour or become a pop of contrast, the key is choosing the right finish and taking the right steps.
Painting radiators is not just about aesthetics but also about selecting a paint that can withstand heat without cracking, peeling, or yellowing over time. That is why knowing which products perform best is essential before you start.
When Should You Paint a Radiator and When Should You Not?
The best time to paint a radiator.
- When the radiator is completely cool and turned off
- During warmer months so it has plenty of time to cure fully before heating season
- After decorating the rest of the space so your colour scheme is already in place and you will not get paint splashes on your newly painted radiator
- When you fancy a change of colour and want to refresh your room’s look
When not to paint a radiator.
- When the radiator is warm as the paint will bubble or not stick properly
- If there is rust, flaking paint, or leaks make sure to address these first for a lasting finish
What Kind of Paint Do You Need for Radiators?
Radiator paint vs. wall paint.
Wall paints are not built for high temperatures and can discolour or peel over time. Traditional radiator paints are specially formulated for heat resistance but often contain strong solvents and chemicals.
At YesColours we offer a durable low-VOC eggshell finish that is an excellent eco-friendly alternative. It is designed to withstand radiator heat up to 120°C without yellowing or peeling providing a smooth soft sheen finish that looks beautiful and lasts for years.
Compared to matt or gloss paints eggshell is easier to clean more durable and offers the perfect balance between subtle elegance and long-term protection.
Can You Use Eco or Low-VOC Paint?
Absolutely. Our YesColours eggshell finish is a fantastic option for radiators. It is low-VOC durable and designed to hold up well to the heat radiators give off. This means you get a beautiful finish that is better for indoor air quality and safer for your family especially important in kitchens bedrooms and living spaces.
Do You Need Primer on a Radiator?
If your radiator is bare metal rusty or previously unpainted you will definitely need an epoxy radiator primer for the best adhesion and to prevent rust.
If it is rusty a red oxide primer is your best friend. This not only seals the surface but also protects your radiator from further corrosion.
If it is already painted and in good condition you might get away with a light sand and paint straight on. However using a primer like Zinsser Bullseye 1-2-3 is recommended for extra staying power and durability. Primer helps ensure the paint adheres properly prevents peeling and extends the lifespan of your radiator’s finish.
How to Prep a Radiator for Painting Without Causing Damage.
Good prep makes all the difference. It might not be glamorous but it is the secret to a smooth long-lasting finish.
Step 1: Clean thoroughly with degreaser.
Radiators collect dust and grease especially in kitchens or near floors. Use a mild degreaser or sugar soap and a cloth to wipe it down.
Step 2: Lightly sand the surface.
Use fine-grit sandpaper around 180 to 220 grit to key the surface. You are not stripping the paint just helping the new paint grip better. Wipe down again to get rid of any remaining dust.
Step 3: Protect surrounding areas with masking or dust sheets.
Use masking tape and dust sheets to protect walls floors and valves from drips or splashes.
Step 4 Prime the radiator.
Use the application method below for this step too.

Best Application Methods Brush Roller or Spray?
Each method has its pros and cons. Here is how to pick the right one for your project:
Brush Best for precision and small details.
Use a small high-quality synthetic brush for detailed work corners and around pipes. Offers great control and less mess.
Roller Good for speed but may need a brush for edges.
A small foam roller is perfect for covering large flat radiator panels quickly but keep that brush nearby for tricky edges.
Spray Pros and cons for advanced DIYers.
Spraying gives a super-smooth finish but you will need proper equipment and ventilation. Each sprayer requires slightly differing quantities of water to paint ratios so it can get a little complicated. Not ideal unless you are confident with a sprayer or can get a professional to help you. Be sure to do a test patch first with this method.

Common Mistakes to Avoid When Painting Radiators.
- Skipping primer on bare or rusty surfaces.
- Applying thick coats without drying time.
Skipping primer on bare or rusty surfaces.
Primer ensures the paint will stick to the surface skipping it could lead to peeling later. And yes this is crucial for rusty or bare radiators but to be honest we think priming no matter what is always your best bet better safe than sorry.
Applying thick coats without drying time.
Thin, even layers are best. Let each coat dry fully before applying the next, this ensures a more controlled application and prevents drips or a textured finish.
