Can granite be sealed permanently?

Granite is a popular choice for kitchen countertops due to its durability and natural beauty. However, granite is a porous material, which means it can absorb liquids and stain easily. To prevent this, many homeowners opt to seal their granite countertops regularly. But, can granite be sealed permanently?

The short answer is no. While some sealers claim to provide permanent protection, the reality is that all sealers will eventually wear off over time. However, there are steps you can take to ensure your granite countertops remain protected and looking their best for years to come.

Discover the Longevity of Sealed Granite: How Long Does it Last?

Granite is a popular choice for countertops due to its durability and longevity. However, when it comes to sealed granite, many homeowners wonder how long it will last.

What is Sealed Granite?

Sealed granite is natural granite that has been treated with a sealant to prevent stains and damage from liquids. The sealant is typically made from a chemical solution that penetrates the granite and creates a protective barrier.

How Long Does Sealed Granite Last?

The lifespan of sealed granite largely depends on the quality of the sealant used and how well it is maintained. In general, a high-quality sealant can last up to 10 years or more before needing to be reapplied. However, it is important to note that frequent use and exposure to acidic substances can shorten the lifespan of the sealant and potentially damage the granite.

Maintaining Sealed Granite

To extend the lifespan of sealed granite, it is important to maintain it properly. This includes wiping up spills immediately, using a pH-neutral cleaner, and avoiding harsh chemicals. Additionally, it is recommended to have the sealant reapplied every few years to ensure the granite remains protected.

The Bottom Line

Sealed granite can last for many years with proper maintenance and care. While the lifespan of the sealant varies, regular maintenance and reapplication can help ensure the longevity of your sealed granite countertops.

Granite Sealing: Do You Need Professional Help?

Granite is a popular choice for countertops due to its durability and aesthetic appeal. However, granite is a porous material, which means it can absorb liquids, stains, and dirt if not properly sealed. This is where granite sealing comes in. But the question is, do you need professional help for granite sealing?

The Importance of Granite Sealing

Granite sealing is essential to protect your countertops from stains, spills, and other forms of damage. Sealing fills the pores in the granite, making it less susceptible to damage. It also makes cleaning easier and helps your countertops maintain their shine and color for longer periods.

Can You Seal Granite Yourself?

Yes, you can seal granite yourself. There are many sealers available in the market that you can use for DIY granite sealing. However, if you want to ensure that your countertops are properly sealed, it is best to hire a professional granite sealing service.

Why Hire a Professional for Granite Sealing?

Professional granite sealing services have the expertise and equipment to ensure that your countertops are sealed correctly. They use high-quality sealers that penetrate deep into the pores of the granite, providing long-lasting protection against stains and spills. Additionally, professionals can assess the condition of your countertops and recommend the best sealer for your particular needs.

Another advantage of hiring a professional is that they can also clean and polish your countertops before sealing them. This ensures that your countertops are free of dirt, stains, and other blemishes, and the sealer can penetrate the granite pores evenly.

While you can seal granite yourself, it is best to hire a professional for granite sealing. Professional granite sealing services can ensure that your countertops are properly protected, and the sealers used are of high quality. Moreover, they can also clean and polish your countertops before sealing them, providing a flawless finish.

15 Year Granite Sealing: Is It Possible?

Granite is a popular material for countertops and other surfaces because of its durability and resistance to scratches and heat. However, granite can still be susceptible to staining and etching if not properly cared for. This is why sealing your granite is important.

But what if you’ve had your granite for 15 years and have never sealed it? Is it still possible to do so? The answer is yes, but it may require some extra effort.

First, it’s important to understand that granite sealers are designed to penetrate the porous surface of the stone and create a barrier that prevents liquids from seeping in. If your granite has never been sealed, it’s likely that it has absorbed some liquids over the years, making it more difficult to seal.

The first step in sealing your 15-year-old granite is to thoroughly clean it. Use a granite cleaner and a soft cloth to remove any dirt, grime, or grease that may have accumulated on the surface. Once the granite is clean, allow it to dry completely before moving on to the next step.

Next, you’ll need to test the granite to see if it needs to be re-polished. This is important because if your granite has become too dull or scratched, the sealer won’t be able to penetrate the surface and create a proper barrier. To test if your granite needs to be re-polished, sprinkle a few drops of water on the surface. If the water beads up, your granite is still in good condition and can be sealed. If the water absorbs into the surface, your granite may need to be re-polished before it can be sealed.

Assuming your granite is in good condition, the next step is to apply the sealer. Choose a high-quality granite sealer that’s designed for porous surfaces. Apply the sealer evenly to the surface using a soft cloth or brush, making sure to cover every inch of the granite. Allow the sealer to soak in for the recommended amount of time (usually 10-15 minutes) before wiping away any excess with a clean, dry cloth.

After sealing your granite, be sure to clean up any spills immediately to prevent staining. It’s also a good idea to reapply the sealer every few years to maintain the barrier and prevent future staining or etching.

In conclusion, it is possible to seal 15-year-old granite, but it may require a bit of extra effort. By thoroughly cleaning the surface, testing the condition of the granite, and using a high-quality sealer, you can protect your granite and ensure it continues to look great for years to come.

Consequences of Skipping Annual Granite Sealing: A Guide

If you have granite countertops or floors, you know how beautiful and durable they can be. However, like any natural stone, granite requires regular maintenance to keep it looking its best. One essential part of this maintenance is an annual granite sealing, which can help protect your surfaces from damage and extend their lifespan.

What is granite sealing?

Granite is a porous material, which means that it can absorb liquids and stains if left unprotected. Granite sealing involves applying a special sealant to the surface of the stone, which fills in the pores and creates a barrier against moisture, dirt, and other contaminants. This helps to prevent damage and discoloration, and makes cleaning and maintenance easier.

What are the consequences of skipping granite sealing?

If you skip annual granite sealing, you can experience a range of negative consequences:

  • Stains: Without a protective sealant, granite can be more prone to staining from spills and other sources of moisture. These stains can be difficult or impossible to remove, leaving your countertops or floors looking dingy or discolored.
  • Damage: Over time, exposure to moisture and other elements can cause granite to weaken and become more prone to cracking, chipping, or other damage. This can be costly to repair and can reduce the lifespan of your surfaces.
  • Mold and mildew: Because granite is porous, it can also provide a breeding ground for mold and mildew if it is not properly sealed. This can be a health hazard and can also cause unpleasant odors and discoloration.
  • Difficulty cleaning: Unsealed granite can be much harder to clean, as dirt and grime can become trapped in the pores and crevices of the stone. This can make your surfaces look dirty and dull, even with regular cleaning.

How often should you seal your granite?

Most experts recommend sealing your granite countertops or floors at least once per year, though you may need to do it more frequently if your surfaces are exposed to heavy use or frequent spills. You can test whether your granite needs to be sealed by placing a few drops of water on the surface; if the water beads up, your sealant is still effective, but if it soaks into the stone, it’s time to reseal.


Annual granite sealing is an essential part of maintaining the beauty and durability of your granite surfaces. Skipping this important step can lead to staining, damage, mold, and difficulty cleaning, so be sure to make it a regular part of your maintenance routine.

While granite sealers can provide long-lasting protection, there is no such thing as a permanent sealer for granite. It is important to regularly reseal your granite countertops to maintain their beauty and durability. However, choosing a high-quality sealer and following proper maintenance practices can significantly extend the lifespan of your granite. Remember to always consult with a professional if you have any questions or concerns about sealing your granite countertops. With the right care and attention, your granite countertops can remain a stunning addition to your home for many years to come.
