Our Top 5 Best Stain Blocking Primers
If you're truly looking for the best stain blocker to use for your next painting project, you're in the right place!
Below is a list of our top 5 stains, keep reading to learn about the pros and cons of each one:
What Are Stain Blocking Primers For Primer?
Stain blocking primers are what you paint on for the first coat to help cover up the surface below and prepare it for the color coat.
Why apply a stain-blocking primer?
Because the color you are painting with might not completely cover up the previous color, and you should always prime drywall before painting for the best results.
Also, you'll end up using significantly less of the finish coat if you fill in all the small pores with primer beforehand.
Here's a helpful video:
What Are The Different Types of Stain Blocking Primers?
Some paints are made specifically for indoor use.
This means that they don't have additives that block out the elements. You might get away with spending less money on an interior primer because it won't include additives that are necessary for exterior paints.
Other paints are designed to flourish in either indoor or outdoor environments.
Most paints sold these days are water-based and less toxic when applied.
If you are painting your whole house, you'll want to use latex because it is less toxic, lasts longer, cleans up easier, etc.
Oil-based primers are a good solution for smaller projects for a smooth finish.
Be careful with oil-based primers when painting over the top of latex paints.
How Do You Prep Your Surface For Stain Blocking Primers?
Priming your paint job goes fast after you have spent the time prepping.
Here are some tips to prep your paint job correctly to avoid mistakes:
Before priming outdoor surfaces like siding, fences, decking, etc, the best thing to do is power wash the surface to remove all the dirt and loose debris from the surface.
After power washing, let the surface dry almost completely.
You might even want to use a pole sander to sand the surface you are painting, but it really depends.
A quick pass with the pressure washer usually does the trick.
Prepping for primer indoors can be as detailed as you want.
For example, if you are using a paint sprayer, you will have to mask off other surfaces with a paint masker to avoid getting paint on them.
Lightly sanding wood and drywall is also a good idea. Just make sure the surface is smooth and clean.
Below we'll go over a few tools you will need for prepping and priming your next paint job!

What Supplies Will You Need To Use A Stain Blocking Primer?
Painting with a sprayer is easier than ever.
You can buy a cheap paint sprayer off of Amazon these days for only a small additional cost to your paint job.
And you don't have to buy the nicest paint sprayer on the market, either. You could try a handheld HVLP paint sprayer that costs under $100 and still get great results when painting(and you'll also get the job done faster in a lot of cases)
How much primer should you buy? Remember that each gallon of primer will cover around 100 square feet, and you'll need more than one gallon to get the job done.
Sanding is necessary before and during the painting process.
All of the drywall mud has to been sanding flat before painting with a sanding pole, and you should also sand the walls in between prime coats with 120-grit sandpaper to make for the best quality paint job.
You'll also want a sanding sponge to help you get the job done.
Sanding sponges work really well for sanding spackle spots and smoothing up trim work like baseboards and doorways.
Drop cloths/paint masker/masking material
When prepping for a paint job(especially spray painting), the best thing you can do is cover up surfaces that you don't want to get paint on.
You'll also want some painter's tape, and some masking film/paper to attach to the paint masker.
Trust us, using a paint masker makes paint prepping 10x easier.
Don't forget that you'll need to stir the primer before applying it.
A razor blade will help you cut the tape accurately on the corners.
Spackle and dye
Use spackle to cover up small imperfections in the wall or whatever it is that you are painting.
You can also buy a blue dye that leaves your spackle a different color so that you don't forget to sand it before painting it.
Caulking is necessary for indoor and outdoor painting projects to help seal in the cracks and keep water and moisture out.
Use a nail set to knock all those finished nails that didn't quite go into the trim work.
Paintbrush/paint roller/spray gun
Last but not least, you'll need the right paint applicator for the job.
For small jobs, a paintbrush or roller may be all you need. For larger surface areas, you might want to purchase a paint sprayer for quick results.
Step-By-Step Guide For Applying A Stain-Blocking Primer
(Click any of the links below to jump straight to that step!)
- Clean And Prep Surface
- Sand And Caulk/Spackle
- Apply A Coat Of Primer
- Sand The First Coat Of Primer/Apply A Second Coat
- Finish Coat
Step 1 - Clean And Prep Surface
The first step to any painting project is the paint prep. We have gone into detail above for prepping indoor and outdoors.
If you are spraying indoors, you'll want to use a vacuum to eliminate any dust that will kick up onto the walls, and outdoor paint jobs usually require a spray down with a pressure washer.
Don't forget to use the paint masker to help you quickly mask off large paint jobs!
Step 2 - Sand And Caulk/Spackle
Sanding, caulk, and spackle will help further seal in the paint job and create a completely flat surface to apply the paint to.
Step 3 - Apply A Coat Of Primer
The paint primer will block out the previous paint color, and give headway to a smooth finish coat that will require less paint compared to if you didn't use a primer.
Step 4 - Sand The First Coat Of Primer/Apply A Second Coat
For projects like softwood, you might want to apply two coats of primer.
You should be able to get away with just one coat of primer for surfaces that are flat and take the primer well.
Lightly sanding after the primer dries with 120-grind sandpaper will help the finish coat go on smoother.
Step 5 - Finish Coat
After the prime coat is lightly sanded and smooth as butter, you can go ahead and apply a finish coat.
Applying 2 coats of paint is also normal, especially on porous surfaces, so don't be surprised if surfaces like redwood require 2 coats of primer and 2 coats of paint when repainting.
Remember, take your time, and do a good job.
You or your customer will be looking at this DIY paint job for years to come, so it's worth the extra time to make it look good.
Good luck! And don't forget to hit us with all of your painting questions on our Pro Paint Corner blog.

What To Look For In The Best Stain Blocking Primer For Painting?
Going for the lowest price isn't exactly a bad idea when buying primer.
Sure, you don't want to buy the cheapest one, for example, Home Depot paints like Behr isn't as recommendable as others from Amazon.
The cheapest primers will be hard to apply and might clog your paint sprayer also, so just keep that in mind when evaluating the price of your project.
Buying in quantity will assure you that you get the best deal on your purchase.
It's always smart to buy online because you can purchase in large quantities, and you will have the paint shipped to your doorstep the next day(or in a few days)
What are you painting? Interior or exterior?
The smartest move when buying primer for a specific project is to research which primer would be the best fit for the specific job.
