Granite Sealer Buying Guide

If you are going to shop for the best quality granite sealer then there are some factors you should keep in mind before finalizing the most suitable one. Here are some of the important points that should keep in mind before purchasing.

Here is a quite good guide on how to seal the granite:

Granite Sealer Types

There are three types of granite sealers. You can choose any of these according to your requirements. These are:

Penetrating granite sealer

As the name suggests this type of sealer penetrates the surface without changing its look. It flows slowly on the surface and creates a film on the top. This prevents the granite top to absorb water or oil-based substances thus keeping it safe from any stains. These are the most common types of sealers used on different types of granite tops.

Enhancing granite sealer

Enhancing sealer as the name suggests is used to enhance the beauty of granite or countertop. It enhances the natural color of the granite surface and maintains its shine and style for a long time. Some of the enhancing sealers can protect the granite top from oil and other stubborn stains but they are a bit costlier.

Topical granite sealer

The topical sealer is somewhat known as a temporary sealer. It does not last long and needs frequent application as it peels off very easily. It is also called a sacrificial sealer as it is very fast and easy to apply on the surface. Besides, it is cheaper in comparison to penetrating as well as enhancing sealer.

Granite Sealer Ease of Use

We should choose a product that is easy to use and is hassle-free. There are a variety of ranges of granite sealers available from spray bottles to the aerosol can. The spray bottle is more convenient to apply compared to the whole can or other bottles. You just have to spray the sealer on the surface to provide it with a protective layer.

Granite Sealer Coating

The coating is the most important aspect in terms of time and the overall cost of the product. Sealers requiring more coating need more time to complete the sealing and also increases the overall cost. A sealer that requires only one coat should be preferred as it is cost-effective as well as time-saving.

Granite Sealer Toxicity

There are numerous organic and water-based products available in the market. Some of the sealers contain harsh chemicals for providing a protective layer.  As you are using this product in your kitchen, it is also very important to protect your food from these chemicals when using granite sealers on the kitchen top.

So, selecting the water-based sealer should be preferred over the chemical-based product as toxicity is also one of the essential features in the case of sealer when buying it.

Granite Sealer Odor

Some of the granite sealers have a strong acidic odor. If possible, just go with an odorless product or the sealer that has a decent smell. However, if you compulsorily have to buy a sealer with an unpleasant odor, the area should be well ventilated.

Granite Sealer Dry Time

Some sealers may take a full day to dry. On the other hand, some sealers dry within an hour or two. It also depends upon the time when you have applied the sealer on your countertop. Applying late in the evening can also take more time to dry completely.

Long-lasting Granite Sealers

Longevity is also one of the most important factors to consider when selecting a sealer. Some products require frequent reapplication while some last for up to 10 years. It is recommended to use the product that gives full protection to your granite and at the same time lasts longer.

Frequently Asked Questions(FAQs)

Q: Does granite need to be sealed?

Answer: It depends on the type of granite of your countertop. Not all granites are porous, requiring sealers. The hard rock granites do not need sealing at all. One more aspect is the color of the granite. Lighter granite, especially white, grey, or any light color, requires sealing to prevent stubborn stains of water, oil, and other substances on the countertop. If you have a dark color granite, sealing is not mandatory.

Having said that, sealing the granite of any color is a good idea to increase the durability and beauty of your granite as sealing repels any substance on the countertop and prevents them from going inside thus protecting granite from any damage.

Q: When should granite countertops be sealed?

Answer: There are some easy experiments that you can do to find out whether your granite needs sealing or not:

  1. Take a tablespoon of water and pour it onto the countertop.
  2. Wait for 10-15 minutes.
  3. Wipe out with a dry cloth.
  4. If there is a darkening of the stone then it requires sealing.
  5. If the color of the granite remains unchanged then it does not require sealing.

Granite such as Black Absolute does not require sealing. Many hard-core granites also remain stain-free without sealing. You should also remember that sealing only protects from staining, not etching.

Q: How long does the granite sealer last?

Answer: Granite sealer is not permanent. Generally, you have to reapply the sealer every 3-5 years to keep the granite protected or as per the condition of the countertop. Some granite sealer lasts very long while some peel out in a very short duration.

Various conditions are responsible for resealing the granite such as the condition of granite before the last sealing, quality of sealer, style of application of sealer, and so on.

Read every instruction thoroughly before applying any sealing product on the countertop. For getting maximum durability the countertop surface should be completely clean and dry before the sealer application.

Q: Can you seal granite yourself?

Answer: Yes, Sealing granite is now a DIY project for all. Anyone can apply a granite sealer. The spray bottle of sealer has made it much easier for us to do this work in very simple and easy steps in a quick time. Remember to read the instructions carefully before applying the sealer and follow the steps for the best results and also to avoid any allergic reactions caused by the chemicals. You can try it on a smaller area first before trying it on a large surface.

Q: What happens if you don’t seal the granite?

Answer: As we all know sealing granite or other natural stone enhances its beauty and longevity as sealing helps to repel the liquid from the surface and keep it stain-free. Unsealed stone absorbs all types of liquids like water, oil, and other substances that make the countertop wet and stained for all time. Stubborn stains give a dirty look to your countertop.

In some cases where the stone is very hard and of dark color do not require sealing. But for light color porous granite sealing is a must to keep it beautiful and durable.

Q: How do you prep granite for sealing?

Answer: There is nothing much required before sealing the countertop. All you need is to clean the countertop with a mild kitchen cleaner. Let it completely dry with the help of a cloth. Use one more dry cloth to repeat the process of drying and confirm the dryness. After completely drying the countertop apply sealer as per the given instructions.

Q: Does sealing granite make it shiny?

Answer: No sealing of granite does not make it shiny. However, the high-quality sealer keeps the shine of granite for longer. Sealer flows inside the stone through a small and porous channel and hardens then. It repels the water and other liquid substances to keep the granite safe from any damage due to moisture.

Only polishes and polishing devices can make the granite mirror shiny. You have to take the help of a professional to repolish the granite. After sealing you can apply some oil to the surface of the countertop to give a shining glow and smoothness to the granite.

Q: Can you polish granite after sealing?

Answer: Actually, you should always polish the granite only after sealing. If water or other liquids seep through the granite, they leave a dark spot on the surface even after polishing. So, countertops should always be sealed before doing polish.

Q: Does sealing granite make it darker?

Answer: Yes, sealing the granite makes it darker, but it is extremely subtle even if you can not differentiate until you place the original stone next to this sealed stone. It does not make any significant difference.

When you apply the sealer probably at that time you will notice a slight difference but it will automatically lighten when it is about to dry and after 48 hours the color will almost be the same as before sealing. If you are using textured stone on the countertop then it will be noticeable otherwise for smooth ones you won’t notice it.
