Frequently Asked Questions
Do I need to prime exterior?
When it comes to residential exterior painting and interior painting, it's usually a good idea to prime before painting, especially if you're coating a new surface, a previously-painted surface that's falling apart, and/or need an extra boost in terms of color coverage.
Do you need to put primer on wood before painting?
However, even if you're working with a previously painted wood plank or surface, you should still use primer on your surface to make sure it holds on to the new color as much as possible.
Which is better interior primer or exterior primer?
For wood, the exterior primers are proved to be better as compared to the interior primers because they are more long-lasting and rigid in nature which results in good protection from buildup, cracking, and erosion. Not every primer works well on wood. There are different primers for different kinds of wood.
What kind of primer to use on unfinished wood?
Like the raw drywall, unfinished woods tend to really soak up paint, and primer helps seal the surface to prevent this from happening. Either latex primer or oil-based primer is suitable for raw wood, depending on the type of paint you will use.
