Best Countertop Sealer

Natural stone is among the most beautiful materials that you can have in your home. From granite to marble and many other stones, you will surely have a countertop that is pleasing to the eye. However, it can only retain its incredible appearance for many years if you take proper care of it. One key aspect of proper care isealing. This guide will provide you with information on sealing and some of the best products that you can use. 

What is Sealing? What Does it Do?  

Sealing is the process of applying a sealer to your countertop to protect the surface from damages. Since most types of natural stone are porous, the material is susceptible to damage from liquid and stains that can penetrate the surface. However, the sealer is designed to absorb into the pores of the stone and harden, which will help to protect your countertop. If properly sealed, your natural stone countertops will stay in great shape for years to come. 

How Often is Sealing Required? 

The answer to this question will depend entirely on what type of natural stone you have. For example, granite will not require re-sealing as often as marble, which is a more porous stone. Below are some of the most common types of natural stone used for countertops, along with information regarding how often you should seal the surfaces. 


Granite is one of the toughest natural stones you can find. It is also one of the least porous options on the market. However, you will still need to seal granite to properly protect it from damages. It is recommended that you re-seal your granite countertops roughly once every year. This timeframe can also depend on the specific type of granite you have, as some lighter colored granite countertops are more prone to damage and will need to be re-sealed more often than darker colored granite countertops. Luckily, you will be able to find many types of granite sealer on the market. 


Marble is more porous than stones such as granite. Marble is a stone that has long been admired for its beauty. It has been used to build everything from countertops to famous statues. But to keep this material pristine, you must re-seal it. Since it is a very porous natural stone, marble must be re-sealed once every few months. Doing so will protect it from common household damages. However, you must also make sure to exercise proper amounts of caution regarding any spills. If you properly take care of your marble countertops, which in part can be done by re-sealing appropriately, the surfaces will retain their elegant looks for years. 


Quartzite, like granite, is one of the tougher natural stone options often used for countertops. In terms of the re-sealing timeframe, quartzite falls in between granite and marble. It is recommended that you re-seal your quartzite countertops about twice per year. With proper sealing, you will be able to enjoy your quartzite countertops for a very long time. 

What Are the Best Countertop Sealers? 

While you will find a seemingly endless amount of sealant products on the market, this guide has narrowed down your options to help you find the best of those products. Using any of the following sealers will be an excellent choice for protecting your natural stone countertops.
