Some experts will recommend sealing granite countertops every “6-12 months” or “3-5 years”, but there is no hard and fast rule. How Often Do You Need To Seal Granite? Granite is a unique and natural material that is extremely durable, resistant to high temperatures, and easy to clean.
Many sealers applied at the factory last 10-15 years, while store bought (DIY) sealers may only be good for 6-12 months. So it's important to know if you had a sealer before, and what type. A simple water test will help you determine if sealer is needed.
Although most granite countertops don't need to be sealed, it does help the stone resist dirt and spills, which can cause etching and staining [source: Marble Institute of America]. By its nature, granite is moisture-resistant -- however, it's also porous. Sealants block liquids from seeping into the granite.
When you don't seal your countertops, they tend to quickly absorb food and liquids, leading to deep stains. Since the countertops are bare, the stains develop within a matter of minutes, even if you are quick to wipe the spill. The countertops not only absorb liquids, but grease and pigments as well.
The good news is sealing granite is an easy do-it-yourself project. Many homeowners seal their granite counters once or twice a year, although you can seal them more regularly if you wish because it is not possible to over-seal natural stone.
Simply get a quality soap film remover to get the shine back. High mineral content in your water (hard water) can also result in a dulling buildup on your countertops. Most soap film removers will do the job, but you can also find combination soap buildup/mineral deposit removers that can tackle both problems.
yes, it is possible to apply a permanent bond sealer. A couple companies (Sensa, Permashield) are offering granite with a permanent sealer pre-applied "at the factory".
If you're up to the task, you can purchase sealant for around $20 from most hardware stores. If you're interested in having your countertops sealed by a local granite countertop pro (which can last longer), expect to pay between $170 to $350.
Yes, you can overseal granite. If the granite doesn't need sealer it won't absorb it and it will pool and dry on top of the granite. It's possible that you already have too much sealer and that's why you're having a problem cleaning.
A sealer will not polish granite or make it shine.
Standard impregnating sealers absorb into the stone and do not affect the color or surface finish, so you can rule out applying a granite sealer. Granite and marble polishing (or polishing any stone to a shine) is done on big machines using intense friction.
If possible, let the sealant cure overnight before returning these objects, but an absolute 24 hours must pass before the surface can be polished. Polishing After Sealing Wait 24 hours before you apply Granite Gold Polish® to your freshly sealed countertops.
30 minutes after the final application, wipe off the excess sealer with a microfiber cloth. If excess dries on the surface and hazing appears, spray additional sealer onto that area and wipe up immediately. Keep surface dry for 24 hours after the application process is complete.
Warm water, mild dishwashing liquid, and soft clean cloth are generally all that's needed to maintain your granite countertop surface. The best care you can give your natural stone is preventive care. By following a few suggestions, your countertops will last a lifetime while maintaining a brand-new appearance.
Water that contains high amounts of iron, for example, may deposit this mineral inside the stone. This permanently darkens and discolors the granite because the mineral will not evaporate with the water.
Ubatuba granite most often does not need sealing because it is typically a very dense, low-absorbency stone that is naturally stain-resistant.
Clorox, whether it is Clorox wipes or the Multi-Purpose cleaning fluid, is not safe to use for cleaning and disinfecting your granite. The multi-purpose cleaner contains bleach, which is extremely harmful for granite and many other natural stones.
Homeowners don't need to worry about damaging their countertops with everyday use because granite is quite heat resistant. Placing a hot pan on a well-maintained granite slab will not cause it to crack or weaken. Just remember that repeatedly placing a very hot pan on the same spot may cause granite to discolor.
Quartz is one of the most appealing and most popular choices for a new kitchen counter because of its durability. Unlike granite, quartz doesn't need to be sealed on a regular basis in order to prevent staining. The nonporous surface makes it an ideal choice for food preparation and maintenance.
Second, a typical impregnating granite sealer like these recommended marble & granite sealers should not darken or change the color at all. A "color-enhancing" sealer will darken the color, but they wouldn't be applying a color-enhancing granite sealer in this case.
Since granite countertops have a sealant on them to keep them shiny and stain-resistant, you want to avoid using anything too acidic or basic on the granite. Frequent use of vinegar, Windex or bleach will dull the granite and weaken the sealant. Instead, a little soap and water should do the trick.
The second type of water stain is caused by hard water (that is, water with a high mineral content) that sits on the counter, dries and leaves a deposit, often resulting in bothersome circles that build up around the faucets. If you find your beautiful granite marred by either one of these types of stains, don't worry.
A filmy haze on granite countertops is often the result of allowing sealer to dry on the surface of the stone. Seal stone correctly by applying sealer in three-foot sections. Immediately buff the sealer into the stone until the surface is completely dry. Never simply apply a sealer and allow it to “soak in.”
