The Best Sealer for Quartzite Countertops

One of the biggest design decisions in a kitchen remodel is choosing your countertops.  Quartz, granite, marble, quartzite – the choices can be overwhelming.  As part of that decision, you need to consider the care and maintenance involved.  We opted for honed quartzite countertops as part of our kitchen remodel, because I loved the look and quartzite is also very durable.  Although one thing I discovered in this process, is that all sealers aren’t created equally. When it comes to sealing out stains, oils and water marks, it took some work to find the best sealer for quartzite countertops. This post contains some affiliate links.

Our fabricator said that since the counters were honed, they may need to be sealed multiple times, and I had them seal the counters twice after installing them (as we were getting water marks after they were initially installed, and he told me to call if we had that issue).  Despite repeated sealing by our fabricator (and myself  with the sealer they recommended), we still were having issues.  

What do I mean by issues?

Water marks were one thing that we encountered.  If you left a glass of ice water on the counter, it would leave a ring from the condensation.  It would go away, but my fabricator warned me about it, and that you didn’t want it.  Over the long term, it could cause the counters to look that way permanently.  Not a good look.

I can’t remember if this is a stain or a water mark, but you get the idea

Stains were another concern.  Oil is something that likes to soak right in to honed countertops and leave a mark.  Not to fear, it can be removed with a product like this, or even a mix of water and baking soda to a paste that you cover with plastic wrap.  It will pull out the stain, and your counters will be fine.  But, it’s a worry that stresses me out, and something I thought the sealer should remedy.

I was frustrated.  The last thing you want to worry about is staining your new countertops, and feeling like you have to treat them with kid gloves.  So, I was on the hunt to find something that worked.

What I tried

I tried two water based sealers (this one and this one) and one solvent based sealer. The first sealer was the same one that the fabricator used.  After continuing to have issues, I opted for the second one. Similarly, I continued to have problems.  I did a deeper dive, and came upon a solvent based sealer that had great reviews.  Specifically for honed quartzite.  Honestly, I think some of these sealants are fine on other surfaces (i.e., granite).  I don’t know if it’s the fact that we opted for quartzite, or that it’s honed quartzite that made it a little more tricky.  We had granite for years, and I never had an issue (although it was dark vs. light like our quartzite).  

In reading through posts in the kitchen remodeling group I’m in, this is not a new issue for some homeowners with quartzite.  But I was convinced I just didn’t have the right sealer.  This problem is a solvable one. Then I came upon this one – Stain Proof Premium Impregnating Sealer. This is the secret sauce.

Suggestions and Precautions

  • This sealer is solvent based, so it smells.  Open the windows if you can, wear a mask, and use gloves when applying it.
  • If your countertop appears darker, and looks as though it’s pulling every stain that had already occurred previously, don’t panic.  I kind of panicked (ok, I totally panicked) when this happened, but the color will come back to your countertops, and the stains that you’re seeing won’t remain.

You can see the spots on the countertop, as well as how it appears darker as I’m resealing it

  • Seal it at least two times for good measure. Since it’s solvent based, the process moves pretty quickly, so it’s not difficult to seal it twice.
  • Allow a full month for the seal to take effect.  Don’t panic if things aren’t perfectly sealed right off the bat.  It’s an impregnating sealer, so it takes time to work into the stone.  But it works! Just be patient.
  • I would also highly recommend this sealer for marble countertops. 

I hope this post is useful to anyone experiencing similar issues with their countertops.  It’s very upsetting to spend a lot of money on countertops and then have to worry about maintenance that you didn’t expect.  I feel confident that I have found the best sealer for quartzite countertops, and am glad to have this product in my arsenal.

What is your favorite countertop surface these days? There are so many to choose from, it can certainly be overwhelming.

    Jenny, your timing is impeccable as I have recently noticed my quartzite (acidic spots) and marble (baking soda toothpaste) stone surfaces are showing damage. No one has steered me towards a workable solution thus far. And then I read your post you are a godess among homeowners. Thank you for your post!!!

    I have white princess quartzite in my kitchen that has some dull green (not green bloom) stains on it. Mostly on the island. I wonder if this would pull those out? that would make me so happy as I love the stone but these stains have really bothered me.

      I would certainly give it a try – it seems to work wonders from the times I’ve used it.

    We just bought a house with a darker granite counter top. Will this work on granite?

    Great article. I do have a question. We remodeled our kitchen in 2021 as well and have polished quartzite. We have not had any problems with staining at all. We are building a home next year and I’ve thought of using honed quartzite there for a more marble-like look. (We’ve always had polished granite and now quartzite.) Would you recommend the honed now that you realize it might take more work?

      I still love the look of honed quartzite and would totally choose it again.

    Nice article, but I have a question. After trying many products on a Brilliant Black Leathered Quartzite(looks more like honed),
    the installer used mineral oil to get the darker finish that we preferred. Is this Ok to use as a sealer? Should we initially apply more than one coat on the countertops?

      I don’t really know anything about mineral oil as a sealer. I would ask your fabricator to find out, but my gut says it would not serve as a sealer. That said, I would find out what kind of sealer you could use on top of mineral oil to make sure there isn’t an issue with the mixing of different materials being an issue, if that makes sense.
