What Happens If You Don't Seal Granite Countertops? If you don't use a granite sealer on your countertops (or you wait too long before resealing granite countertops), they will: Absorb food, grease, and liquids — causing set-in stains on your countertop. Absorb water — making the countertop always look dirty.
A properly sealed countertop repels water, causing it to bead up on the surface. But if it isn't sealed in a place where water is constantly used – like the kitchen and bathroom – water will penetrate the stone and leave behind water marks and a dirty appearance.
Most granite is very stain resistant and does not “require” sealing. However, sealing is an added precaution, and many fabricators and installers do recommend it. Quality Granite & Marble typically makes this determination, and applies sealer when needed.
You might think something as natural as water wouldn't be a problem, but it is. Without sealing, water will penetrate the stone and leave behind water marks, some small, some large, giving your stone a perpetually dirty appearance.
Many professionals recommend sealing granite countertops at least once each year. If you cook frequently in your kitchen and use the countertops daily, you might need to reseal the granite even more frequently.
One test for determining whether or not your countertops need sealant is to add several drops of water on top of the granite, in several locations. Let it sit for 30 minutes. If the water has penetrated the surface within and has darkened the granite, it is time to reseal.
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.
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".
Why Seal Granite? Granite, like many natural stones, is porous. At least once every five years, a sealant should be applied to prevent staining from oils, water and other liquids. If your granite countertop is properly sealed, liquids and oils will bead on top of it rather than seep into the stone.
In general, we recommend using a washcloth or sponge and a gentle soap and water to remove dirt and food debris. Dry thoroughly after washing with a clean, dry towel. Avoid harsh abrasives or highly acidic solutions which can scratch and dull your granite countertops. Bleach can also dull the granite surface.
Most (but not all) granite countertops will need sealing upon installation and then resealed every 1 - 5 years depending on the color and porosity of the granite, the quality of the sealer, and proper sealant application.
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.
Granite surfaces feature tiny pores that can absorb liquids, staining the surface. Thankfully, granite is one of the least porous natural stones. When properly sealed, it won't stain at all. But over time, the seal on your granite counter will start to deteriorate, leaving it open to stains.
Mica In Granite Countertops Explained:
Granite slabs used for countertops are made up of several different minerals… quartz, feldspar, and in some cases mica. Mica is usually what makes the granite slab look beautiful by giving off a reflective three dimensional appearance that sparkles.
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.
Keep the Surface Dry for 24 Hours
Once you're done sealing your stone, you can place items on the countertop and use the surface, but make sure it stays completely dry for at least 24 hours before polishing, as this gives the sealer time to cure and bond with the granite's pores.
When your granite countertop is properly sealed, daily care is a breeze. Just use a soft cloth to dust the surface, or wipe it down with plain water or a mild soap. If your countertop needs extra cleaning, use a specially-formulated stone cleaner with a neutral pH. Never use abrasive cleansers or harsh chemicals.
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.
Over time (usually in excess of one year), improper cleaning (such as not completely removing food and beverage spills or residue contained in smoke from cooking) attacks the granite's color and clarity. As a result, the granite's surface becomes much darker in color compared than when it was new.
No, not all granite countertops need a sealant. Sometimes, granite comes sealed from the manufacturer. For instance, here at Atlantic Granite & Marble, we use a 15-year lifetime sealer. Granite is an igneous rock that contains various natural stone materials that can be prone to stains and scratches.
Quartz is actually harder than granite and thus, more durable. In fact, quartz is nearly indestructible, and because it isn't porous like granite, it's easy to keep your countertops relatively bacteria-free.
Granite is a very hard substance and is not susceptible to scratches. While not ideal to work on because it will dull knife blades, it will take normal wear and tear very well. Granite resists heat too, so its use near a range or cooktop is ideal.
