Buying Guide: Granite Sealer

There are different granite sealers, so don’t assume they’re all alike. Variations can occur in the strength, active ingredients, and even quantity of the product. Choosing the right granite sealer involves considering several factors.

Number of Coats

A longer process will ensue if you need to apply for more coats. A number of coats will elevate the cost of the product as well. Products that work with just one coat are quicker and more cost-effective.


It is important to avoid breathing in toxic chemicals while applying granite sealer. There are a number of organic and water-based products available today. The formulas are chemical-free, so your lungs and the environment are safe.


There are some granite sealers that have a strong and somewhat acrid aroma. It is therefore important to ensure the area where you apply them is well-ventilated. Nevertheless, there are products available that are odorless and even have pleasant scents.

Food Safe

When installing granite countertops, it’s important to ensure that they are food-safe. The countertop will not leach chemicals when your food touches it.

Drying Time

Drying certain products may take up to 24 hours. If you plan to use your granite countertops later on in the day, this may affect them. A few products dry quickly and provide complete protection within a few hours.


One last consideration is how long the chosen product will protect your granite. You may need to reapply for some products every couple of months. There are other products that provide long-lasting protection.

Ease of Use

Your product choice must be easy to apply and as quick as possible. Products that can be sprayed are ideal. Using these products is as simple as spraying them onto the desired product and letting them work.

It is important to consider the durability of a sealer when choosing one for granite. Granite sealers should be both water and oil-resistant, as well as suitable for use both internally and externally. Make sure whichever sealer you choose will be durable enough.

Frequently Asked Questions

Does sealer darken granite?

Sealers tend to darken the stone just slightly, but they shouldn’t make a noticeable difference. There is usually no discernible difference between the two. As long as a sample of unfinished stone is not placed side-by-side with the counter for comparison, little difference will be noticed.
When applying the sealer for the first time, you may notice that there is a change in tone, but there is no need to worry. The finish should lighten within 48 hours of drying and curing. Surfaces with texture will show the effect more strongly, while smooth surfaces will not.

Can sealer make granite look wet?

It’s true that some sealers can cause granite to appear wet. Their gloss is enhanced by adding a substance called a gloss enhancer. Reflecting light makes the stone’s surface shiny with a gloss enhancer. Brightening colors can also be achieved this way.
Sealers sometimes contain wetting agents as well. Wetting agents help spread out water evenly on surfaces. Wetting agents help the sealer create a damp appearance on granite when combined with gloss enhancers. The fact that not all sealants contain gloss enhancers or wetting agents is important to note.

How Long Does It Take To Seal Granite?

You need to seal granite for varying amounts of time depending on the product that you use. The cure time for some products can reach 72 hours, but for others, there is no wait time at all. You will also have to factor in the area you are covering, the type of product, and the tools you are using. Application times can range from 15 minutes to several hours, depending on various factors.

Is oil suitable for sealing granite?

Sealing granite with oil is not possible. People usually use oil for wood, but not stone. Besides dulling the look of granite, oil also promotes mold and mildew growth. Oil should be replaced with granite or stone sealers. Granite sealers are specially designed for sealing stones.
