QUESTION:

I have a black/brown mottled granite counter top that was sealed over a year ago and tried to seal it again today.

The sealer I used today caused it to become sticky and hazy...

How do I remove it before it becomes cured? Thanks

ANSWER:

You will likely be able to remove the granite sealer, but you'll have to strip it off.

You may be able to do this be re-applying and then removing the actual sealer again, but you'll probably have to use a solvent like acetone (or methylene chloride if granite sealer is stubborn) to strip it.

You'll find complete instructions about how to determine when to apply and/or re-apply granite sealers, how to properly apply and strip off if necessary in the All About Sealing e-book.

The problem here is not the sealer's fault. Unfortunately, it's yours (or whoever told you to do it).

You stated a granite sealer was applied one year ago. Well, even though you may see online and even some installers will tell you that you "must" re-seal annually", it's almost never the case.

First, very few granites (or any other stones) are so porous that they need re-sealing annually.

Depending on the sealer and quality of application, most granites will go 3-5 and some cases 10 years before needing re-sealing.

And many granites never need sealing because they are so dense they are essentially non-absorbent and nearly stain-proof naturally.

Since there is such variation among different granites and even within the same color, there is no "set" rule about when to apply a granite sealer.


The only way to accurately determine if a granite countertop (or any stone) needs a granite sealer in the first place is to perform water test for sealing granite countertops.

This test will tell you if your granite could be sealed and then it's up to you to decide if it should be sealed based on the intended use and installation location.

Also, when the test is regularly repeated on previously sealed stone it will tell you when/if the stone is ready for re-sealing.

Applying a granite sealer based on a recommended guideline will get you into the exact trouble you're in now.

The reason this sealer has left a sticky haze on your granite countertops is because it could not absorb into the stone, which it must do.

When a granite sealer dries on the surface, whether it could not absorb or it was simply left on the surface (wrong technique) it will leave the streaky haze.

The sealer you used likely could not absorb because the granite countertop was sealed just a year ago.

Again, frequency for applying a granite sealer will depend on the stone, the sealer and the quality of application.

One exception is the SenGuard Marble & Granite Sealer, which forms permanent bonds.

Once you effectively seal the countertop with SenGuard you will not have to apply it again like you would with every other sealer on the market.

So, follow the instructions in the e-book and once stripped, then test because it may be that after stripping the sealer your granite could use a proper application of a new granite sealer.

Removing sealer streaks and stickies immediately
by: penny

I have a dark grey mottled granite countertop that I hadn't sealed for 2 years. Feeling very guilty, I sealed it today and was left with sticky streaky spots (like so many others). I immediately got online to see what to do about it, and found your website. Not wanting to have to strip it, I immediately went back to the counters, and using my daily granite cleaner/restorer and the non-scratch side of my sponge I started rubbing vigorously and wiping away the excess with paper towels. I'm pleased to say that the residue came off nicely. And a large glass ring (probably from our peanut butter jar) that appeared when I sealed it, also came off with my "fix". Thanks for the advice. I'll be buying some products when it comes time to address our bathroom marble.

Good Job! Yes, if you immediately address the sealer dried on the surface you sometimes can remove the streaky residue with simple cleaning methods.
