You spent good money on those countertops. They were gorgeous on install day — and honestly, they still look pretty good. But somewhere in the back of your mind, you’re wondering: does granite need to be resealed, or is that just something people say?
It’s a fair question. And the answer might surprise you.

The Short Answer: It Depends on Your Stone
Not all granite is created equal. Some varieties are dense and relatively low-maintenance. Others are more porous and absorb liquids faster than you’d expect. The condition of your existing sealer — and whether you ever had a quality one applied in the first place — matters just as much as the stone itself.
What’s consistent across the board? Granite is an investment that benefits from the right protection. The question is whether yours still has it.

The Granite Sealer Test You Can Do Right Now
Before you assume your countertops need attention (or dismiss the idea entirely), there’s a simple way to check.
The water drop test:
- Place a small splash of water — about the size of a quarter — on your granite surface
- Leave it for 10 to 15 minutes without wiping
- Come back and take a look
- Water beads up and sits on top — Your current sealer is likely still doing its job
- Water soaks in and darkens the stone — Your granite is absorbing moisture, which means its protection has worn down and it’s time to act
Here’s what you’re looking for:
This isn’t a perfect diagnostic, but it’s one of the most reliable at-home indicators homeowners have. If your stone is drinking up that water, it’s also vulnerable to oils, wine, juice, and everyday spills that can cause staining over time.

So How Often Should You Seal Granite?
The honest answer: there’s no universal schedule. Variables like how heavily the surface is used, what cleaning products you’re using, and the quality of the original application all play a role.
What we can tell you is that generic DIY granite sealer products from the hardware store — the kind you wipe on and buff off — tend to sit on top of the stone rather than bonding with it. They wear off. They wash off. And they leave you wondering, a few months later, whether they did anything at all.
This is one of the most common frustrations we hear from homeowners: “I sealed it myself. Why is it still staining?”

What Makes Professional Granite Sealing Different
HydroShield’s approach to granite and stone protection isn’t about slapping on a coat of something and calling it a day. Our products are formulated to covalently bond to SiO2-based surfaces — which includes granite — creating a protective layer that works with the stone rather than just resting on it.
The result is protection that lasts significantly longer than what you’d get from a DIY product, and a surface that’s genuinely easier to clean and maintain day to day.
That’s not a sales pitch — it’s just a meaningful difference worth understanding before you spend an afternoon with a hardware store bottle and end up back at square one.

You Deserve to Stop Wondering
Granite maintenance shouldn’t be a source of stress. Your countertops should be something you enjoy — not something you worry about every time someone sets down a wine glass.
If the water drop test gave you pause, or if it’s simply been a while and you’re not sure what was originally applied, it’s worth getting a professional opinion.
Reach out to a certified HydroShield technician near you. We’ll help you understand exactly what your stone needs — no pressure, no guesswork, just honest answers from people who genuinely care about protecting what you’ve invested in.
