For anyone wanting to paint over a metal surface, metal priming paint is an absolute must. But why?
Metal priming paint gives a better result
When you apply primer to a metal surface before you paint the main colour on, you’ll get a much better end result that will last much longer, too. However, it’s not always easy to know which type of metal priming paint to use. Check out the quick guide below:
There are two main types of metal priming paint
Oil-based and latex-based are the two main types of primer. Oil-based primer is ideal for any surface likely to be exposed to high levels of wear and tear, such as metal doors or outdoor furniture. They work well at covering up existing rust, too.
Latex-based primers, on the other hand, work well on smaller metal items, such as metal cabinets or shelving.
When it comes to choosing a brand of oil or latex-based primer, you’ll need to keep a few things in mind, such as:
- What paint you plan to use for the final coat
If you plan to use an oil-based paint for the final coat, you’ll need to select an oil-based primer. If you plan to use a latex-based paint, either type of metal priming paint can be used.
- What level of coverage you require
For smaller surfaces, such as a metal cabinet door, a spray primer might suffice, whereas for larger items or structures, you’ll need a primer that comes in a canister.
- The primer’s drying time
If you’re working on a project with a short deadline, check how long the primer will take to fully dry. Some primers take as long as 24 hours to dry, while others will take much less time.
What are the different types of primer paint for metal?
You have a few options available to you when choosing a metal priming paint, and there are pros and cons associated with each one. While a conversation with a paint supplier will help you, the following information will provide you with a basic guide:
These are designed to stop rust from forming on painted metal surfaces, and can be used with great effect in areas where moisture or humidity is present.
With properties that help paint adhere to any metal surface, this type of primer works well when the surface of the metal is pitted or uneven.
If a metal surface is likely to be exposed to high temperatures, or is tricky to paint, then this primer is the best one to use.
If a metal surface is going to be exposed to harsh chemicals or abrasives, then this primer is the one you’re going to need. It will also be effective when used on metal surfaces that are hard to paint.
While it’s highly important to use a primer when painting any metal surface, it’s just as important to choose the right one. If you still have questions about which primer is best for your needs, you can check with a local paint and primer supplier or manufacturer.
