Features to Consider before Buying

Before you order one of these products, you will need to keep the following features in mind:

1. Bonding Between The Molecules

You need to buy a product that is strong in terms of bonding among the molecules. The stronger the bonding, the securer will be the protection. For example, the Tenax Hydrex is a great product with strong bonding between the molecules. 

Strong bonding will also create a stronger, impenetrable barrier which is extremely necessary for keeping the granite surface safe from harm and corrosion. Stronger barriers also keep moisture away from the surface that keeps the stones safe from the destruction of nature.

2. The Time Necessary to Dry

This is very important because if the sealer does not dry off easily, it will be more time-consuming. In most of the cases, you will have to apply the sealer multiple times to get the best results. To do that, the surface needs to be completely dry first.

If you want to make sure that you are buying a product that dries off quickly, you can check the description for how long it takes for the product to dry off completely. For instance, the Tenax Hydrex granite sealer takes only about 5-10 minutes to dry off before the surface is ready for another round of coating.

3. Applicator

This feature is more important than you think because without the applicator, the sealer would be tough to use. Some of the sealers come in spray bottles which you can easily use to spray the liquid onto the granite surface. Sometimes, the applicator comes separately, but along with the package.

In some of the most disappointing cases, applicators are not included in the package. For example, the Black Diamond Next-Gen Granite Sealer doesn't come with an applicator. If you do not have a spare applicator lying around at home, you will have no other way of applying the sealer.

In such cases, you will have to order a sealer separately, or buy one from the local market. If that is the case, make sure that the applicator fits the bottle perfectly. Otherwise, the applicator will be of no use.

4. Number of Coatings Required

Some of the granite sealers require multiple coatings to get the best effect. On the other hand, in some of the cases, only one and a maximum of two layers of the product were sufficient to bring out the best in the stone. Before buying, look for the instructions and check whether multiple coatings are necessary.

It is always better to buy the ones that do not require multiple layers because multiple layers mean more product and more effort. However, in case of products that do not need multiple layers, you will only be wasting the product if you do not know that a single layer is enough for bringing out the protection and the shine.

For example, the Rock Doctor Granite Sealer needs to be applied 3-4 times to give the maximum granite protection and to bring out the shine in the granite.

Types of Granite Sealer

Based on the functions and how the work is done, sealers can be of three different types:

1. Penetrating Sealer

Exactly as the name suggests, these kinds of sealers penetrate the surface of the stone and block the pores so that other substances cannot seep through. These sealers do not create an extra film; instead, keep the surface of the stone natural.

Likewise, they are great for protecting your granite from basic stains like tea, coffee, ink, wine and other substances that can stain the surface. In other words, these sealers can provide moderate to high level of protection to the surface.

2. Enhancing Sealers

The name says it all. Enhancing sealers improve the color and look of the stone. It means that it modifies how the granite looks originally. These products are mostly oil based and give your granite surface protection from oil-based stains that can leave marks behind.

They also make the color of the stone more vibrant, but it does not, make the surface shinier. It enhances the color of the stone but leaves the other aspects alone such as the shine of the stone.

3. Topical Sealers

Topical sealers give your granite surface an excellent glossy finish. They do not seep into the stone surface like the penetrating sealers but produce a shiny and silky transparent film over the top of the surface. This quality makes the surface more polished than other sealers can make.

These kinds of sealers also wear off more easily than other types of sealers. To keep these sealers and their gloss intact, you need to be apply more often to the surface of the stones than other kinds of sealers.

Although this particular feature makes these kinds of sealer a little inconvenient to use, the gloss that these produces is worth the pain.

However, the sealers in our review are all penetrating sealers.
