When painting walls for the first time or repainting old walls that are faded or peeling, primers are useful for ensuring a perfect coat of paint that stands up to the test of time.
What is interior primer used for?
Interior primer is used before painting surfaces and forms a smooth layer that paint can easily stick to.
Which interior paint primer should I use?
Multi-purpose primer is a good choice if you'll be painting or repainting a lot of surfaces. For bare drywall, a drywall primer is the best option as it prevents dull and discoloured areas from forming.
Do you need primer for interior painting?
If you're painting a bare, new surface, taking the time to apply a coat of primer can help the paint stick better and more evenly, and also helps prevent fading and flaking so your paint looks flawless longer. Some primers are designed for high-moisture areas and will block stains and prevent mildew.
Is there a difference between interior and exterior primer?
Outdoor primers are formulated for greater resistance against moisture, so humidity, rain, and dampness don't soak into your walls. Otherwise, there aren't too many differences between the two types of primer.
