So, first, check our buying guide before picking up a stain-blocking primer. Then, check on the features and price. Last, check on the compatibility with your style. If you don’t want much trouble, then a spray would be a better option. But, if you are traditional, then maybe, liquid one will be a better one. They also last better than spray one.

Anyway, the decision is yours. So, make an informed one.

Factors to consider while buying

To pick up a stain-blocking primer can be a tough job for some. In this buying guide, you will find the features you need to explore before purchasing.

Liquid and spray Primer

The primer comes in two forms – liquid or spray. There’s not much difference between both of these forms. They both do the same job.

Yet, the application process is different. You require a roller or brush to apply liquid paint. Then again, spray paint, typically, comes in a can. Thus, you can merely spray it.

Between you and me, spray form is more comfortable to use.

Odor and stain-resistant

As you’re purchasing this primer to clock stain, you must see if it’s stain-resistant. On top of it off, if it blocks odor, that would be Christmas, isn’t it?

Drying Time

We don’t have all the time in the world to work on a single project. So, pick up a primer that doesn’t waste much of your time.

Finishing color

Primers come in a wide variety of colors – gray, black, and white. But you might be surprised to know that it necessarily doesn’t disturb the paint color that you’re planning to use. So, make sure your primer leaves a beautiful finish.


Versatility ensures that you can use the primer on different surfaces. Who doesn’t want to kill two birds in one stone? Pick up a primer that works on literally anything.

Now, you are ready to grab the best stain blocking primer with confidence.
