You just paid to have granite countertops installed in your home or you purchased a new home with granite countertops and you want to know if sealing granite countertops is necessary.

In this article, I am going to tell you why it is important to seal your granite countertops and how often to seal your granite countertops.

If you have marble countertops or quartz countertops then check out the sealing marble and sealing quartz articles. If you are researching granite countertops because of a stain in your countertops then be sure to educate yourself on getting stains out of granite.

Is Sealing Granite Countertops Necessary

Yes, sealing granite countertops is necessary. If you do not seal your granite countertops you run the risk of stains and dull countertops.

If anyone ever says that sealing your granite countertops is not necessary then they are wrong. People ask me why they need to seal their black galaxy granite or black pearl granite because a stain will not show up. That is also not true. Dark granite and black granite can and will stain.

When a black granite stains it darkens in areas. Also, grease stains on darker granites look worse than anything. Sealing your granite will prevent from this happening to you.

What Happens If You Don't Seal Granite

If you don't seal your granite you will start to notice areas of your countertops looking dull, having stains, and may start to feel a texture in your countertops.

Just like anything if a colored liquid is left on the surface you will notice the liquid soaking up into your granite. This is because granite is porous and once a stain has entered through the pores of granite it is almost impossible to remove it. You could try Mangia Machia which is what I use, but that is not always a guarantee to remove any stains.

It is always best to prevent issues before they are even an issue and that means sealing your granite countertops. Don't know which sealer to use? This article goes into depth on the best granite sealers and even my favorite and most recommended sealer.

Are Granite Countertops Sealed When Installed

Granite countertops are not always sealed on installation. Some granite companies do seal their granite countertops after they are installed but even the best installers can forget to seal your newly installed granite countertops due to fatigue or just being in a hurry.

If you notice they are dry as they are leaving then it is very likely that they did not seal them and you need to ask them to before they leave. If you weren't present during install then you can perform the water test to ensure that your countertops are sealed.

How Often Do You Seal Granite Countertops

Granite countertops need to be sealed at least once per year. I always recommend that you seal them every season or every 6 months. This will ensure that your kitchen countertops are protected. Include a daily granite countertop cleaning habit and you should be fine.

Choose the best granite sealer for better performance and less maintenance requirement.

Can You Seal Granite Yourself

Yes, you can seal your granite countertops yourself. Follow the instructions on the bottle of granite sealer to achieve the best results.

Also, be sure to wear gloves when applying sealer. This will save your hands from the oil or any chemicals.


An ounce of prevention is worth a pound of cure. This saying is one of my favorite and it is true in this case. Sealing your granite is extremely important and absolutely necessary.

About Jon - Website Owner

Jon Smith

Hi, my name is Jonathan Smith. I have been in the granite business for many years and have worked my way up from an installer helper to an installer and then a countertop business owner. 

I started my countertop company with very little and grew extremely fast because of my knowledge and helpfulness. I started this countertop resource for 1 main reason. That reason is that there are no countertop websites with all the correct information and none of them are from an industry expert like myself. 

I am still in the trade every single day installing countertops, educating people on the type of material they are using for their homes, and making people's dream kitchens a reality.
