Picture this. It is snowing outside, and you’ve just made a cup of hot chocolate to drink in front of a cozy fire. You sit down to watch some TV when you suddenly notice that the paint on the inside of your fireplace is looking a bit worse for wear. Even though you’ve been putting it off for a while, it’s finally time to give your fireplace a few coats of heat-resistant paint.
However, you may not know where to get started and what the best brands for heat-resistant paints are. Thankfully, that’s where we come in to help you! This guide will take you through a list of the top 15 best heat-resistant paints. We’ll explain what these paints are, how to apply them correctly, and how to choose the perfect heat-resistant paint that best suits your needs.
Let’s dive in.
What are heat-resistant paints?
Quite simply, heat-resistant paints are specially designed to resist extremely high temperatures that fluctuate often. Good heat-resistant paint protects the surfaces it is painted on from grease, corrosion, heat, dust, flames, and smoke, depending on where the paint is used.
This type of paint becomes heat-resistant because manufacturers combine different inorganic pigment powders with polysilicon alkoxide, a binding agent. Depending on the brand and the concentration of ingredients, heat-resistant paints can withstand temperatures over 315 degrees and higher. They can even go up to nearly 400 degrees in some cases!
Heat-resistant paints are generally either silver or black, but they also come in shades of red, yellow, orange, dark grey, and white.
How to apply high-temperature heat resistant paints correctly
When applying high-temperature heat resistant paints, it’s important to note that you must do the following:
- First, allow the surface you are about to paint to cool down. For instance, you might be painting an exhaust pipe, grill, wood stove, or radiator. No matter what surface you’re about to paint, you must let the surface cool completely so that you can apply the paint properly.
- Next, clean the surface. Using a dry cloth, rub the surface firmly to eliminate any dust, dirt, or grime so that it doesn’t get stuck to or mixed with the paint.
- Prepare the surrounding areas. For instance, if you are painting part of a car, use masking tape to cover the areas you don’t want to be covered with paint, and place drop cloths or old newspapers on the floor so that you don’t make a mess.
- The application of the paint depends on whether you’re using heat-resistant paint from an aerosol can or a bucket.
If you’re painting a surface using a can of paint, make sure you shake the can thoroughly for a couple of minutes, then hold it at least one foot away from your desired surface. Spray the paint evenly in a thin layer, let it dry, and then repaint it with at least two more layers.
If you’re painting the surface by using a brush, try and refrain from going back and forth multiple times. Apply thin layers of paint with the brush, let them dry, and then go back and add one or two more coats.
