This is good because if you choose to use all three products, you are only applying sealant when you want, instead of every time you clean. Some stones are more porous than others and may do better with one particular brand over another. Remember that nearly all stone is naturally porous and no sealant lasts forever.

However, because natural stone is porous, you’ll need to seal them if you want to keep them stain free and looking like they were installed just yesterday. Here’s what you need to know about some of the best sealers for granite so you can keep kitchen surfaces looking new for decades.

Granite and most other natural stone surfaces are extremely durable, but like all natural surfaces, they are also porous, allowing them to absorb spills and stains over time. Ensure that the surface you’re treating is clean and dry before sealing. Let stand 2-3 minutes and then wipe dry using clean cotton or paper towels.

Advantages Of Not Using Granite Sealer by

However, granite in itself is non-porous and resistant to most contaminants. This makes it one of the most durable building materials ever used by mankind. Since not all homeowners can seal granite with accuracy and efficiency, sometimes, professionals need to do the job for them. In addition, the granite needs to be sealed periodically—every two years or so.

Trapped moisture is like a time bomb; when the water is heated inside, it turns to vapor and the pressure build up can cause the granite to crack. To ensure that the granite preserves its natural color, it is recommended that it should not be sealed. Reducing friction on the granite is a potential accident risk because people may slip when walking over it.

Unlike other types of material used in floors, countertops, and walls, granite is quite hard and not easily scratched.

This entails spending money on the service fee and cost of materials. When the granite sealer becomes dull, it has to be rebuffed, which again costs a lot of money. When moisture is trapped inside the granite, the sealer will not allow the moisture to escape, thus adding potential damage to it. However, not using granite sealer will ensure breathability of the material and therefore reduces the risk of damage. Sealers may release toxic fumes in the air or cause irritation on the skin. Since it has a natural color already, it does not need to be coated with anything to make it look better. The problem with sealing is that it may cause discoloration or stains.

Which Granite Sealer To Use? by

First and foremost, be sure to perform the sealer application test to determine if you even need to seal the stone. The only issue is that lighter colored granites and particularly white granites are the most absorbent and prone to staining. Note that sealing does not form an impenetrable film over the surface. On most granite this absorption time can be improved to 20 or 30 minutes or more. Just perform the “water test” prior to sealing to get a baseline absorption time and then perform the test again after each coat.

Long story short, after three years of discussion, the manufacturer and the store agreed to replace our stone.

And this will typically happen more around the sink due to all the water and constant impact occurring in this area. Maybe you’ve had trouble removing a lot of stains and it is true that stains can “become” (key concept) impossible to remove when left for years. However, such stains constitute a miniscule percentage of all marble and granite stains that occur. So, in light of this paying for an relatively expensive sealer warranty (far more expensive than the actual cost to remove a stain) isn’t a good bargain.

By having to seal only one time, you save from throwing away bottles of other sealers that require re-application. While it may save you the trouble of re-sealing, you’d have to re-seal 3 to 10 times (depending on the sealer you use) before granite shield would save you money.

Many sealers on the market will do an adequate job sealing granite countertops. A true comparative test would need several years with samples undergoing “normal” use and cleaning, or at least some type of an accelerated process that simulates years of use in a short time. Most of the recognized brands are now of this type (which is no longer the most advanced formulation). Development of high-quality permanent stone sealers has left these behind. Using nano-technology it’s the most advanced and durable sealer technology yet invented. However, it will need periodic re-application , so time / effort / cost catches up with you in the end. Permatreat can only be applied by a licensed technician (expensive). It doesn’t break down every brand, but it does thoroughly cover this topic, so consumers can get a detailed understanding about sealers. Sealing it will help prevent this, but some white granites can be so porous that even when sealed water and other liquids may absorb in 15 minutes or less.

Sealing dramatically increases the absorption time to allow you more time to clean spills, etc. Keep applying additional coats of sealer until you don’t see any more improvement (increase) in absorption time. After six years, we had an issue with a crack in front of the sink – oxidation jacking. The old stone had developed many pits and pocks and chips around the sink area and was rough to the touch. If you get pits again, then just fill them using this repair kit for pitting and chipping in granite, marble, quartz. However, we take the consumer’s point of view and detail the pros and cons of any stone care issue.

While it is true that some sealers will require re-sealing this quickly, there are several sealers on the market that will easily last 5 year and up to 10 years on some stones.

Depending on how often you use the countertops and how light or dark the granite is, you may need to seal it anywhere from every three months to yearly. Always consult the specific instructions on your sealer for minor differences. Porous surfaces may require another application after the first 10 minutes.
