Radiator colour faded over time but could be easily fixed with paint. Radiator paint is not a rare product. Almost all hardware shops are the easiest option to get spray paint. And the finishing is perfect as traditional painting. You can apply the paint to make your radiator colour again. Spray painting tax very little time but not that easy to get prepared. You will need specific things for completing the preparation of colouring a radiator. The things are the following. 

Radiator Spray Paint 

Choose the colour you want, check on the body of the bottle. Check also how each cover can fill many radiators. 

Sugar Soap

It is used for cleaning material that composites of variable things. It is used on the affected surface and also for domestic cleaning materials. 

Dust Mask

It is a flexible paper pad mask. It is used Against non-toxic dust and inhaling dust or sand. 

Masking Tape 

It is an adhesive tape used to cover areas while painting to avoid paint on which part is not wanted. It is known as painter’s tape also. It is a pressure-sensitive tape. 

Plastic Sheets

It is a floor barrier sheet that comes in long rolls. It protects against spills and scratches. 


Sandpaper is made of different grit sizes and is used for removing materials from the surface. It smooths the objects. 

Consider the colour based suited to your radiator. Consider whether your radiator is old or new. The colouring depends on whether your radiator is metallic or some other materials. You can apply the focal paint to freshen up the old radiator. If you turned off this for a long period, then the metallic one should be applied paint. 

Pick The Right Primer and Paint for A Metal Radiator

Prime and paint radiator can be covered best around all the curves If you use a can spray paint. In this case, use oil base aerosol primer. Oil or water-based paint will depend on the level of your interior metal surface. The different radiator needs a different type of primers. 

If you put your radiator unused for a long time, you should go for rust-resistant metal spray paint. You should use the Primer and paint both the rust-resistant type. 

If you want to paint which radiator hits your house, then the paint and the Primer should be rust-resistant as well because your radiator will catch rust when the temperature remains cool.

Choice of colour depends on the specific type which intended effects. The selection of paint is available as the intention is. If you want to blend in as the surroundings are, then choose shady ones. Blend it to get the shade of the colour of your wall behind the radiator. To contrast with the background wall, choose a perfect hue colour. It will be a nice combination of the radiator and the existing colour of your room. 

Make Ready The Radiator 

It is required when your radiator remains unused for a long time. But for a running radiator, you have to make it ready before colouring. Please turn off the radiator, turn the control valve clockwise to the limit until it’s fully closed. Give time to the base unit being completely cool down. Put on masking tape and tape the control valve area—also, tape the steam valve area and the air ventilation side. Paint the ventilation area can block the valves, so avoid painting on the operational unit. 

Prepare The Working Area

Apply masking tape around the perimeter. The wall around the radiator should be clothed and lay drop on the floor. Thoroughly protect the surface and wall area from the overspray open. You can open the window of the room for a proper ventilation process. Don’t forget to wear gloves and a respiratory mask. 

Sand The Metal Radiator 

A metal radiator should be checked whether it is previously painted or not. A screwdriver bleed can be used for flaking to confirm that. If there is no flaking, start applying sandpaper, then sand the surface to make it smooth and paintable. If it’s painted previously, then check it with a lead paint test kit. This testing kit will cost around 15 pounds. The paint radiator is most likely to have a lead.

Remember never to scrape or even sand the surface of the radiator that is coated with lead. The risk factor of spreading the lead particles will be dangerous. Normally, it can adversely affect your nervous system. If accidentally inhaled or swallowed, then it can be fatal.

The high level of exposure the lead should be avoided. So, be aware during sanding or stripping away. For the cracks of the painting, you can use the following methods for further safety. 

• Use a putty knife to scrape away the cracked, especially from the radiator surfaces. 

• Have a professional to refinish the cracked from the paint, or even you can use an environment-friendly soy-gel paint stripper for removing. It will keep lead particles growing airborne. 

Wipe Away The Dust 

With a tack cloth, clean the radiator surface by removing sanding dust. Let the radiator dry after wiping with water-dampened clothes. 

Spray Paint Primer on The Radiator 

For the appropriate metal spray, Primer holds the sprayer from one foot away from the radiator. Spray a single coat of Primer to the overall surface. Let the Primer dry completely. Usually, it takes 24 hours before painting to dry out. 

Paint The Radiator 

Apply the same technic used for Primer for a metal spray paint; spray a single coat first. At the high temperature, spray it over the radiator’s whole surface in a side-to-side motion. Lead the first coat dry for 10 minutes, then apply another coat. For your measured coat depth and colour, allow drying each coat for at least five to ten minutes. Relatively minimize the succession paint in the previous coat. Finally, lead the coat dry completely. 

Cleaning up

Remove the painter’s tape from the wall, and the valves discarded the drop cloths and turned the radiator control valve counterclockwise. 

Paint can roll the time back to turn things into new. Like any paint project, there are some rules for painting a radiator. I hope the step-by-step process helps you to paint a radiator.
