What Is Granite Sealer

Granite sealer is a product that protects your granite countertop from staining or etching.

Granite sealers have come a long way over the last few years. Technology has improved and as a result, so have granite sealers. In this article, my goal is to inform you of the best granite sealers to protect your granite countertop investment.

As a granite professional, I have tried and tested numerous granite sealers and have compiled a list of the top-performing sealers. The sealers were rated based on several factors including quality ingredients, ease of application, the longevity of the sealer, price, and protection offered.

Granite Is Stone Why Do I Need to Seal My Granite?

At first glance, granite countertops seem to be sturdy. They are made of stone, after all. Many people think that all it takes to keep granite looking great is a damp cloth to wipe up spills; however, those spills can cause a lot of damage to the surface of the granite countertop.

During daily use of the kitchen, moisture and oil can damage the surface of the granite if the granite countertop is not adequately sealed. This damage can result in the loss of shine, and staining can occur. Many stains are surface stains; however, liquids and oils can seep into the granite’s pores, resulting in deep stains that may be permanent.

In addition to stains, acidic substances and chemicals can etch the finish of granite and cause permanent damage. If the damage becomes severe enough, the granite can begin to crack or crumble, requiring the entire countertop to be replaced. Applying a high-quality sealer to your granite will protect against staining and etching.

How Do Granite Sealers Work?

Sealing your granite is not difficult and can help protect your granite countertops from damage. Most granite sealers work in the same way; however, many people are confused about how sealers work. Here is how granite sealers work.

A granite sealer, often listed as an impregnator, is composed of resin that has been dissolved in either a petroleum-based or water-based solvent. The sealer is then applied to the countertop and allowed to absorb in the pores of the stone before wiping away the excess sealer. As the solvent evaporates, the resin hardens, creating a barrier that will slow down the absorption rate of the granite.

Stains like oil, coffee, fruit juices, and wine can still stain the stone if allowed to remain on the granite countertop’s surface for an extended period of time. The granite sealer reduces absorbency and reduces the risk of staining; however, no sealer will make your granite countertops impermeable.

How Often Should Sealer Be Applied?

The porosity of the granite, along with the quality of the sealer, can affect the longevity of the sealer. On average, you should expect to reapply sealers every three to five years; however, some sealers are rated to last ten years or longer. To get the maximum longevity out of a sealer, you must properly care for your countertops.

The quality of the sealer affects the longevity of the product. Over time, the resin will degrade due to use as well as the type of cleaning products used. Choosing a pH-neutral cleaner designed for granite countertops increases the longevity of the sealer.

How well the sealer is applied can also affect the longevity of the granite sealer. Read all of the instructions on the sealer and follow them explicitly to increase the longevity of the sealer. More information on how to determine if your countertops need to be resealed can be found HERE. We are also including best practices for applying the granite sealer later in this article.

The granite itself can affect how often you should seal your countertops. Lighter-colored granite countertops are typically more porous than darker-colored granite countertops. However, it’s important to note that no matter the color of the granite countertops, they will stain if they are not adequately sealed.

Determining Which Sealer To Buy

If you have ever look for a granite sealer, you have probably noticed that sealers come in a wide variety of prices and offer different features. All of these choices can make it challenging to choose the best granite sealer for your granite countertops.

To save you the time of trying to determine the best sealer for you, we have tested numerous granite sealers and developed a list of the top five granite sealers on the market. Choosing one of these sealers will ensure your granite is protected against staining and damage for many years to come.

Understanding Two Types Of Granite Sealers

When choosing a sealer for your granite, you should choose one that is designed to protect against staining and damage on natural stones. Although certain sealers may not specifically list granite, if it is designed for natural stone surfaces, it is safe to use on granite surfaces. However, one that implicitly is designed for granite will provide the optimal benefits.

There are two types of granite sealers on the market – water-based and oil-based sealers. Oil-based sealers typically have a strong odor and require adequate ventilation. Water-Based sealers have an odor; however, their scent is not as strong as oil-based sealers.

Granite is a living stone that contains different-sized pores. These pores allow liquids and oils to enter into the granite, resulting in stains if the granite is not adequately sealed. A penetrating sealer, also known as an impregnating sealer, soaks into the pores and fills them up to prevent water and oil from entering the granite.

An enhancing sealer is a penetrating sealer; however, it enhances the granite’s natural colors and textures. Enhancing sealers come in a variety of sheens, including gloss and natural finishes.

Topical sealers are less effective than penetrating sealers and should not be used to protect your granite surfaces. Instead of soaking into the granite and blocking pores, penetrating sealers provide a protective layer on the surface of the granite only. Topical sealers may look great; however, they can leave your granite vulnerable to stains. These sealers require frequent reapplication and multiple coatings.

How Can Sealer Improve Your Granite Countertop Lifespan?

Granite sealers are designed to protect your granite and reduce the risk of stains and damage caused by acidic and caustic substances.  To minimize the risk of damage, you want a sealer that offers longevity. A high-quality sealer will have a ten-year or longer lifespan. In order to maximize the lifespan of the granite sealer, proper care should be taken. Cleaning your granite with a pH-neutral cleaner designed for granite will help extend the life of your granite and granite sealer.

What Are VOCs And How Can I Protect Myself?

VOCs are volatile organic compounds. Examples of VOCs include phosphate and ammonia. These compounds have an extremely unpleasant odor, which can be irritating if breathed. To prevent nausea and the other symptoms associated with inhaling VOCs, always use the proper protective equipment, including disposable gloves and eye protection. In addition to this, make sure you provide adequate ventilation by opening the windows up and using a fan to remove odors and bring in fresh air.

What Are The Different Active Ingredients in Granite Sealers?

When it comes to granite sealers, you want to choose a sealer that will provide you with long-lasting protection against stains. Reading the fine print will help you determine the best sealer for your granite countertops.

Some resins will need to be reapplied each year while others will last three to five years or even ten or more years. Understanding the different types of sealers will help you decide on the best sealer for your unique needs.

  • Silicon Resin – Silicon resin is the least expensive type of resin sealer on the market. The resin evaporates quickly and will lose its effectiveness faster than other sealers. Silicon resin was the first resin used to protect natural stone countertops. It is rarely used by manufacturers today. Silicone-based sealers typically rely on solvents to carry them into the pores of granite. Although they are great at repelling water, silicone-based sealers are not good at repelling oil.
  • Siloxane Resin – Siloxane and silane-based resins are an improvement over silicon sealers. These sealers tend to last longer and cure better. You can expect approximately five years of protection before needing to reapply the sealer. Siloxane resin sealers are more expensive than silicon-based sealers and offer better resistance to water and oil stains.
  • Fluorocarbon Aliphatic Resin – Fluorocarbon Aliphatic resin is the most expensive sealer. This carbon resin sealer will provide you with years of protection. These sealers last the longest, providing up to ten years of protection. Furthermore, fluorocarbon aliphatic resin does not evaporate or deteriorate. This type of sealer is water-based and does a great job at repelling oil.

In addition to the type of resin used in the sealer, the percentage of resin used in the formulation along with other stain inhibitors can enhance the performance of the resin. Purchasing a high-quality natural stone sealer results in less frequent applications and offers better protection against stains.

Was My Granite Sealed When It Was Installed?

This depends on the manufacturer of the granite. Some granite companies seal the granite before shipping it to the consumer; others do not. Contact your countertop specialist to determine if your granite countertops were sealed during the manufacturing process or if the countertop installers sealed your countertops after installation. If the retailer is unsure, perform a water test to determine if your granite countertop needs to be sealed.

If after the water test you are still unsure, it is best to reseal your countertops as this will not hurt anything.

Does Your Granite Countertop Need to Be Sealed?

Maybe. It depends on the type and color of granite. Darker-colored granite countertops may not require sealing. Dark-colored granite is denser than lighter-colored granite. A denser granite will not absorb liquids and stain like many light-colored granites. However, certain light-colored granites may be dense and will not need to be sealed. Therefore, it is wise to do a water test on your granite to determine if it needs to be sealed.

A water test will help you determine how quickly your granite will absorb liquids. If the granite absorbs liquid quickly, it will need to be sealed to reduce the risk of staining. If, on the other hand, the liquid remains on the surface, your countertop may not need to be sealed.

How Often Should Granite Be Sealed?

The length of time that a granite sealer lasts is dependent on several factors, including how you use your granite countertops, the type of sealer used on your granite countertops, and the cleaner used on your granite countertops. Although many sealers state that they last for ten or more years, most will need to be reapplied within three to five years.

The best way to ensure your granite is still adequately protected is to perform a water test each year. If the water test reveals the granite does not offer adequate protection, reapplication is necessary. Applying sealer will help keep your countertops looking amazing and easy to clean.

How To Apply Granite Sealer?

Applying a sealer is not difficult; however, there are a few things that must be done to ensure the sealer adequately protects your granite. We have provided step-by-step instructions on how to apply granite sealers; however, different sealers require different application processes. Read the instructions on the label and follow those instructions if they differ from the step-by-step instructions listed below.

  • Step One – Clean Your Granite Thoroughly – Your granite countertops need to be clean to ensure a uniform application. To clean the granite and prepare it for sealing, use a pH neutral stone cleaner and wipe dry with a lint-free cloth. Next, you will need to use a degreaser to ensure no oily substances remain on the surface of the granite. The final cleaning step is to wipe the countertop down using denatured alcohol. Allow 24 hours for the granite to dry completely before going to the next step.
  • Step Two – Protect Yourself – Before beginning the application process, you should open the windows to help ventilate the area. Put on a pair of chemical-resistant gloves and wear a pair of safety glasses before using the sealer. A granite sealer can produce harmful or unpleasant vapors during the application process; however, once the sealer has cured, no harmful or toxic chemicals will remain.
  • Test in an Inconspicuous Location – Before you begin applying the sealer to your entire countertop, you want to apply a small amount of the sealer in an inconspicuous location like a corner or where a countertop appliance will set. Follow the instructions on how long to leave the sealer on the surface before wiping it up. If the sealer discolors your granite or leaves a residue, stop the application process, and choose a different granite sealer.
  • Apply the Sealer – Evenly coat the surface of the granite using a lint-free cloth or brush that has been moistened with the sealer. The countertop should be damp; however, it should not be soaked.
  • Wait – The sealer must have time to absorb into the granite. Read the instructions to determine the length of time the sealer should remain on the surface of the granite. If left on too long, discoloration on your countertops can occur. Conversely, if the sealer is not left on long enough, it will not have time to absorb into the granite and ensure adequate protection against staining.
  • Wipe Off Excess Sealer – After you have waited the recommended length of time, wipe off any remaining sealer using a clean, lint-free, absorbent cloth. Leaving sealer on the surface of the countertop can create a hazy appearance.
  • Additional Coats – Read the granite sealer’s instructions on how long to wait in between coats of sealer. Then follow the three steps listed above (apply the sealer, wait, and wipe off excess sealer).
  • Curing the Sealer – Once you have applied the final coat of sealer, allowed it to absorb into the granite, and wiped off the excess sealer, you must allow the sealer to fully cure. The exact time needed to cure can vary from product to product. For example, some products protect against water damage in as little as 30 minutes; however, to ensure the granite sealer has fully cured, you will want to wait 48 hours before washing the countertop or placing heavy items on the countertop.

Granite countertops are beautiful and will provide you with many years of enjoyment if they are properly cared for. The first line of defense to keep your countertops looking great is to ensure they are adequately sealed with a penetrating granite sealer. Granite sealers slow down the absorption rate to help reduce the likelihood of stains by filling in the pores of the granite.

Although a granite sealer helps protect against stains, you must wipe up spills as soon as possible. For best results, use a pH-neutral cleaner daily or any time a spill occurs. Finally, a granite sealer will periodically need to be reapplied to provide optimal protection and keep your countertops looking great.
