Does Granite Stain? What You Need to Know

Granite countertops have been the centerpiece of many homes over the last few decades and are still the most popular natural stone choice of homeowners. But before purchasing granite countertops, many homeowners ask the following question: Does granite stain? This guide will give you the answer to that question, as well as other helpful information about caring for your new granite countertops. 

Can Granite Stain? 

Yes, granite can stain. However, it is very rare that it actually does. Since granite (and other natural stone) is porous, liquid and stains can penetrate the surface. That being said, granite is less porous than many other types of natural stone. For example, a natural stone such as marble is much more porous than granite. 

Will Water Stain Granite? 

Water is highly unlikely to cause a stain on your granite countertop. Any water that is absorbed into the stone will likely dry out within 15 to 20 minutes. But while water should not cause any issue, you will need to watch out for oil and grease. Both can stain your granite countertop if you are not careful. 

How Can You Avoid Stains? 

There is a simple way to avoid stains on your new granite countertop: Sealing. In order to stay protected from stains and liquid damage, you must seal your granite. Sealing is the process of applying a sealer to the countertop, which then makes its way down into the surface and fills the pores of the stone. Once the pores are filled, no liquid or stains will be able to get under the surface. 

How Do You Seal a Granite Countertop? 

Sealing a granite countertop is a quick and easy process. To start, you will need to find an ideal sealant for your countertop. There are many products on the market, but some are more effective than others. Once you have done this, mask off any areas that you do not need to seal. Then, apply the sealer with a brush (or spray it on if it comes in a spray bottle). After you have applied the sealer to your countertop, let it sit for 15 to 30 minutes. If you see that it has absorbed during this time, apply a second coat. Once you have waited the proper amount of time, wipe off any excess sealer. Lastly, wait at least 24 hours for the sealer to cure.

How Can You Get Stains Out of Granite? 

If your granite countertop is already stained, do not panic. Stains can be easily removed if you are proactive. You can remove the stains by using a poultice or a paste. The particular ingredients that make up the poultice will depend on the type of stain. Never attempt to clean the countertop or remove the stain using harsh products like bleach. Doing so can further damage your granite. 


While it is not likely, it is possible that your granite countertops can become stained. If this happens, you will be able to remove the stains easily if you are proactive. Overall, granite is one of the least likely natural stones to have issues with staining. Through following this guide, you will know how to prevent stains and keep your granite countertops in great shape.
