Is Stix Really A Good Primer?

Is Stix really a good primer?

You might have heard the hype about INSL-X Stix bonding primer but is Stix really a good primer?
The short answer is Yes! In many cases, you will be amazed at the adhesion that this primer promotes.

What is Stix primer?

Stix is a waterborne bonding primer that will stick to glass and tile if prepped right.
The resin type of this primer is an acrylic urethane. Which means that there is almost no odor compared to solvent-based primers.

After it is dried, which usually occurs in 16 hours, it becomes a hardened film that can be top-coated with almost any product.

You can use Stix for interior and exterior jobs.
It will dry in temperatures as low as 35 degrees Fahrenheit.

Does Stix primer block stains?

Although Stix is a great bonding Primer it will not block stains or tannin bleed.

Especially if you are painting with light colors.

If you are using Stix to paint oak kitchen cabinets I would suggest doing a second coat of water-based primer such as Benjamin Moore Fresh start.

In most cases, you will encapsulate any stains.

But if there is still a brownish stain visible you will have to spot prime those with an oil-based primer.

Any aerosol will work great for that.

Is Stix primer thick?

Stix is not thick and can be applied in one thin coat.

It has the consistency of chocolate milk almost.

You can brush and roll or you can spray it on without any major learning curve.

Does stix need 2 coats?

Stix is for creating an adhesion promotion between your substrate and your paint.

Therefore, you do not have to apply a heavy coat or even a second coat.

One Coat is enough.

It is not a high hiding primer so if you are expecting a white canvas after priming then I would suggest using BM FreshStart again as a second coat.

It will give you a super white base that is great for when you are painting light colors over it.

In Conclusion

Stix is a great bonding primer. One of the best if you do not want to use solvent-based (oil) primers. Unfortunately, it is not a very good stain blocker and it takes 16 hours to dry. We still absolutely love it here at 518 Painters.

Do not let that discourage you from making this your go-to water-based primer.
I would not suggest using it for raw wood or any wood that is known for tannin bleeds such as Cedar and Redwood.
Other than that, if you clean and prep your surfaces right, you will have great success with this primer!

  1. Thanks for this article. I was thinking of using Stix as a durable undercoat for mdf cabinet doors. J was going to roll on shellac seal coat to keep the fibers from raising, then do a couple spray coats of Stix. Do you find that it sands crisply?

    Thanks again

    • Sounds like a plan! I have great success wet sanding stix. I’ve heard other contractors say it doesn’t sand well for them but for me, it seems to work well.
