Experience and Tips

Over 80% of Hammerite reviews are positive and happy with the results of this radiator paint.

Apart from the smell, the only other issue is running among reviewers. Although this is down to poor painting skills.

When you use this paint it must be run out and not puddles. Applying too much of this paint because it’s very thick it will run and ruin your paint job.

  • Make sure you sand as much excess radiator paint before applying
  • Apply long paint strokes up and down the radiator
  • First, apply a thin coat and then add another coat, do not try and do this in one coat of paint because it runs very easily.


  • Great brand at a good price
  • Bright white finish perfect for radiators
  • Dries quickly in about 8 hours
  • Once dried my radiator looked amazing
  • 2-year guarantee


  • Will run easily if too much is applied
  • The smell is strong and can last for a few days

What are users saying? (User Reviews)

“Hammerite worked great after a failed attempt by a cheaper brand. I found it easy to apply but the smell was much stronger. After a few days, the smell went and I was left with a bright white radiator. Happy with this product and would recommend.”

Review by Hanna K.

“Hammerite was a good experience and pleased with the results. Be careful of running paint, I found a few about an hour later, but just run them out again. Apart from that this paint is top-notch stuff and works as advertised by the company.”

Preparing Your Radiator For Hammerite

Preparation is a must for a radiator, if you do not sand your radiator then you will find that the paint will start to rub off in sheets.

You must lightly sand your radiator to give the radiator paint a key to connect to.

If you are just going to paint onto a slippery surface such as a radiator then your paint job will fail.

Use fine sandpaper so you get a nice finish before brushing on the paint.

  • Always sand down a radiator before painting
  • Use fine sandpaper such as 150-160 grade
  • Take the sheen off the face of the radiator
  • Apply two thin coats so it does not run
  • Do not turn the radiator on until the paint has dried


If you are looking for bright white radiator paint then Hammerite has produced strong heat resistant paint that works every time.

Apart from the smell which many Hammerite reviews reveal, the results are amazing and are currently the best seller here in the UK.
