Heat resistant paint is not an everyday paint. To make it clear, a heat-resistant paint is not intended to counteract the effects of the sun. No, we are talking about paint that can withstand very high temperatures.
Depending on the type of paint, this can rise to even 650 degrees Celsius. By this I mean that up to those high temperatures the paint does not flake off at all and does not even become liquid. So what are you thinking about? For example, radiators, stoves, ovens, heating pipes and so on. Heat-resistant paint can be applied with a brush or with an aerosol.
Heat resistant paint also needs proper preparation.
As always, with any painting job, heat resistant paint also needs proper preparation before painting. Here too we start with the basics. The main thing is to thoroughly degrease the object with an all-purpose cleaner. This removes the excess fat. It is also important that you remove any existing rust with a steel brush. So do this in this order. Clean first and then remove rust. After this you will sand with sandpaper grit 180. Make sure you sand everything well. If there is an item where there are small corners, use a scotch brite for it. After that, clean everything thoroughly. If you want to be sure that all dust has been removed, it is best to use a compressor for this.
When this is ready, apply a primer or primer that is suitable for it. When the primer is completely dry, you can apply the heat-resistant paint. To get a good result you need to apply at least 2 layers. Wait about 8 hours before applying the second coat. When painting a radiator, you should make sure that you paint when it is turned off. There is a heat resistant paint on the market called Still Life. You do not need to apply a primer with this paint, which is ideal in itself. However, this heat-resistant paint is only resistant to 530 degrees Celsius. You will then have to check in advance whether it is suitable for your object. Does anyone know if there are other ways to paint objects or surfaces that can withstand high temperatures? Let me know by leaving a comment below this article so we can all share.
