An easy way to tell if your granite surface is "thirsty" is to pour some plain old water on the surface. If the water begins soaking into the stone immediately, then the stone needs to be sealed. This 'water test' enables you to see just how absorbent the granite is at a given time.
The best way to tell when you need to reseal your countertops, is to test them! Sprinkle a couple drops of water on top of your granite and let it sit for 30 minutes. If the water has disappeared, penetrated the surface, and darkened the granite, it's time to reseal.
Granite is a Porous Material
Although granite is a hard and durable stone, granite is porous. This means if you spill something and your granite countertops aren't sealed, it could cause permanent stains and unsightly marks. Brand new granite counters often have a sealant applied during installation.
Typically, granite should be resealed every 12 to 18 months. Nevertheless, there are some other factors that come into play when determining how often to reseal granite countertops. For example, a lighter colored granite will need to be resealed more often because it is typically more porous.
Clorox and Lysol sprays and wipes are convenient, but they are not safe for granite countertops. They rarely contain bleach, but they do generally contain citric acid to help remove soap scum. Avoid using bleach as well.
Resealing granite prevents permanent damage to the stone and restores the original, factory shine. There are many sealers to choose from, but your granite countertops retailer should recommend the best product for your exact variety of stone.
The answer is yes, you can permanently seal your granite and that will give you a completely maintenance-free countertop.
It is like any other natural material. Wood has its grain, and stone has its pores. Fortunately, it's easy to seal a granite countertop. It takes just a few minutes and requires little more than a granite sealer and a clean pad.
Granite is 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.
Choosing the Right Sealant is Essential
For this reason, look for products in the class known as impregnating stone sealers. They are chosen by professional contractors for sealing granite, marble, and slate countertops. The top-rated product in this class is Tenax Hydrex Impregnating Stone Sealer.
It's important to understand that an impregnating sealer should not alter the color or finish of the granite counter. It won't make a polished surface dull, or a matte counter shiny. It's invisible when dry.
A few '15-year' sealants are some of the best chemically engineered sealers available. They penetrate deeply into the stone and provide superior water & oil repellency. However, like all sealers, '15- year' sealers cannot prevent etching and unfortunately, they do not prevent stains for 15 years either.
Unsealed granite countertops will soak up anything that is spilled on the surface. Put a few drops of water on the granite, leave it on the countertop for a few minutes. If you come back and see that the water is gone and soaked into the granite it is time for the stone to be resealed.
Duration. A good granite sealer can last anywhere from six months to five years. However, even if your countertop is sealed, be sure to clean it regularly.
After scraping away the residue and cleaning the stone with water, you can use a polishing powder to restore the shine. These polishing products are safe for most stone. You will need to reseal the stone after completing this process. Another option for small areas is Stone Scrub or Acetone to remove residue.
If it beads up, you have a secure seal. If after a few minutes the water has soaked into the granite, then it's time to reseal the stone. DON'T: Use harsh or abrasive cleaners and sponges. Windex; acidic cleaners, like vinegar, lemon, lime; or anything with ammonia or bleach should be avoided.
Keep surface dry for 24 hours after the application process is complete. This is so the seal can completely cure and bond with the pores of the stone. After 24 hours perform the water test on all key areas of the surface.
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.
Once you have applied the resin or epoxy, you will need to give it time to dry before sanding it down and resealing the area. Large cracks in granite will require professional intervention. In some cases, you won't be able to save the granite, and you will have to consider replacing the countertops.
A granite countertop is durable, aesthetically pleasing, and easy to clean. Since this material is porous and tends to absorb water, it's prone to etching after wear and tear. To prevent permanent damage to the stone surfaces in your kitchen or bathroom, you may need to seal them.
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.
Is a Rough Granite Countertop Surface Normal? If grit is present on your granite countertop, it is likely due to poor quality granite – an issue which cannot be solved readily without countertop replacement. In some instances, grout particles may flake off from newly grouted backsplash, although this is less common.
Make a mixture of three parts baking soda to one part warm water, and combine until smooth. Apply a thin layer of the paste to your granite surface, and gently buff with a clean cloth. Wipe away any residue with a damp cloth and dry the granite for a smooth, shiny surface.
However, vinegar should never be used on your granite countertops. Vinegar is made up of acids that can severely harm your granite. Even if it is diluted, vinegar may still leave acids on your granite countertops. This can cause your natural stone countertops to etch.
