Painting the radiator (heating) with ordinary turpentine based paint is a small job to do.

Radiator paints are best painted with a turpentine based paint.

It is better not to use water-based paint because it becomes very hard when it is dry and the radiator becomes hot.

Painting the radiators

Cracks can appear in the paint and the paint layer can even peel off.

This does not make the radiator more beautiful and after that you can start painting the radiator again, but in the right way.

You do not necessarily have to use radiator paint to paint a radiator.

You can also use normal paint.

The difference is in the pigment.

The paint for a radiator is always white and therefore does not discolour when you heat it.

A color does have a pigment and can therefore discolour when the radiator is heated.

I would choose off white or cream white myself.

Painting radiators is not a big job.

Painting the radiator is not really a big job.

It is of course always important that you prepare well.

We assume a radiator that has already been painted once.

You start with degreasing with an all-purpose cleaner.

I use B-clean myself because you don’t have to rinse it.

Before you start, let the radiator cool down.

Then you sand with a grit P120 and make the radiator dust-free.

If there are still rust spots, treat them first with a rust preventative.

You can use hammerite very well for this.

Other bare parts use a primer.

When this has dried well, you can coat the radiator with a paint based on turpentine.

Then opt for a satin gloss.

If there are grooves in the radiator, first paint them with a round brush and then divide the boards with a roller.

Wait at least 24 hours before turning the radiator back on.

In principle, it will start to smell a bit, but you can absorb this by placing a bowl of vinegar on the windowsill.

Vinegar neutralizes paint smell.

So you can see that painting a radiator is really a simple job.

Painting heating with the right method and painting heating in different ways.

Painting heating with the right method and painting heating in different ways.

By painting a heater I mean painting radiators.

After all, radiators are full of water and this water is heated and gives off heat.

It always feels wonderfully warm.

If you have new radiators, these still look nice.

You have to ask yourself why you want to paint this one.

Is it from the physical point of view or do oddities appear.

Physically you may want a different color that fits better with your interior.

Or are they old radiators that have some rust and are not a face..

I can imagine both then that you want to refurbish that radiator.

In the following paragraphs I will discuss what you should pay attention to when purchasing such a paint, its preparation and implementation.

Heating painting what paint should you take.

When painting a heater, you must know which paint to use.

You can ask for advice at a paint store near you.

The employee in that store can then tell you exactly which paint to use.

Or you can look it up on Google.

You then write: which paint is suitable for a radiator.

You will then be able to visit several sites where you can easily find your answer.

Very handy right? And you don’t have to leave the house anymore.

If you continue reading this article, I’ll give you some pointers.

A radiator is made of metal.

You will then have to choose a metal paint or radiator lacquer.

Then the radiator must be completely intact.

By that I mean that the paint that is on it can still be called completely good.

When you see rust on your radiator you will first have to apply a primer.

In this case, it is best to take a primer that you can apply to many surfaces: a multiprimer.

The word multi already indicates it to some extent.

After all, multi is several.

You can apply a multi-primer on almost all surfaces.

Just to be sure, ask or read the description on the paint can.

Do you want more information about multiprimer? Then click here.

You can also prime the entire radiator with a multi-primer.

After that, you don’t necessarily have to use a metal paint.

You can also use a normal alkyd paint or acrylic paint.

If you take an acrylic paint you will not suffer from yellowing later on.

Radiator painting and preparation.

The preparation you need to make is the following:

Make sure you have enough space around the radiator to paint.

Remove curtains and net curtains that are close to them.

Also make sure to cover the floor.

Use a stucco runner for this.

A plaster runner is a cardboard sixty centimeters wide that you remove from a roll.

Take a length that is longer than the radiator.

Paste the stucco and secure it with a tape to prevent it from sliding.

Make sure you have the following attributes ready; primer, paint, owatrol, bucket and cloth, degreaser, scotch brite, brush, vacuum cleaner, brush, roller and paint tray, stirrer.

Central heating and the execution.

With a central heating you must first degrease properly.

Read more about degreasing here.

Then you’ll sand with a scotch brite.

This scouring pad makes it easier to get into the grooves of the radiator.

Then you remove the dust with a brush and again with a damp cloth so that the dust is completely gone.

Now you are going to start priming.

For the deep grooves, use a brush and other parts a ten centimeter paint roller to finish the entire radiator.

When the primer is dry, sand it lightly and make it dust-free again.

Then you take the paint and add some Owatrol to it.

Owatrol has, in addition to several functions, a rust-resistant function.

This will prevent rust in the future.

Read information about owatrol here.

Stir the owatrol through the paint well and start painting the deep grooves with the brush.

Then take the paint roller and paint the other surfaces of the radiator with it.

So you can see that painting a heater is not that difficult.
