When To Use One Coat
Using one coat of primer is the best situation. Not only will it save you a bunch of time. But it also keeps the project affordable.
Slight Change in Color:
When there’s a slight change in color you will only need one coat of primer. (e.g. The wall is tan and you’re painting it white)
If your previous walls were painted with oil or latex, you will only need one coat. Keep in mind that it’s important to know for sure before you paint as latex paint will not stick to an oil enamel surface. If necessary give your local contractor a call and see what their opinion is.
You will only need to apply one coat of primer if the primer has stain blocking power. The number of coats will also depend on the type of stain. It’s vital that you know what primer to get or it could completely ruin the project costing you money and time.
Greenboard is water-resistant drywall. Its commonly found in bathrooms, kitchens, or any places that might have humiliation or water build-up. This will only need one coat of primer as the primer can easily cover the drywall and give you a great canvas for the new paint.
Paint & Primer In One:

Unpainted wood is just like painted wood. You’ll only need one coat of primer. This is great to hear for anyone that's looking to do an affordable yet quality paint job.
When To Use Two Coats
Painting Over A Dark Color:
When you paint over a dark color such as brown, black, maroon, etc. it's going to take more coats of primer. This is because the primer won’t be able to completely eliminate that dark shade. For example, if you have a dark brown wall and you put one coat of primer. The final paint job will have a much darker shade than when you first bought it. This can ruin the entire project and even cost you some money.
When you’re painting over finished drywall there will be no issue. But when it comes to painting unfinished drywall, you'll come across a few issues such as bubbles, blotches, and just not absorb correctly. Again, this will ruin the entire project, so either applies multiple coats or finish the drywall to save time.
Looks Like It Needs More:
One way to see if you need primer is if it just looks like there’s not enough. A good priming job you won’t be able to see much of the previous color but if its too thin you'll easily be able to see the old paint job. This is a great and easy way to get the right amount of primer.
