How to choose the right sealer for granite tile?

Hey there! As a granite tile supplier, I've seen firsthand how important it is to choose the right sealer for your granite tiles. Granite is a beautiful and durable natural stone, but it's also porous, which means it can absorb liquids and stains if not properly sealed. In this blog post, I'll share some tips on how to choose the right sealer for your granite tiles, so you can keep them looking great for years to come.

Understanding Granite Porosity

Before we dive into the different types of sealers, it's important to understand the porosity of granite. Granite is a natural stone that is formed from cooled magma. It's made up of various minerals, including quartz, feldspar, and mica. These minerals give granite its unique color and pattern, but they also make it porous.

The porosity of granite can vary depending on the type of granite and how it was formed. Some types of granite are more porous than others, which means they are more likely to absorb liquids and stains. To determine the porosity of your granite tiles, you can perform a simple water test.

• Water Test: Pour a small amount of water on the surface of your granite tile and let it sit for 10-15 minutes. If the water beads up on the surface, your granite is less porous and may not require a sealer. If the water is absorbed into the tile, your granite is more porous and will need to be sealed.

Types of Granite Sealers

There are two main types of granite sealers: topical sealers and impregnating sealers. Each type of sealer has its own advantages and disadvantages, so it's important to choose the right one for your needs.

Topical Sealers

Topical sealers are applied to the surface of the granite tile and form a protective layer that prevents liquids and stains from penetrating the stone. These sealers are typically made from acrylic, urethane, or epoxy, and they can provide a high-gloss or matte finish.

• Advantages:
  • Easy to apply
  • Provide a high level of protection against stains and scratches
  • Can enhance the color and shine of the granite
• Disadvantages:
  • Can wear off over time, especially in high-traffic areas
  • May require frequent reapplication
  • Can make the granite surface slippery when wet

Impregnating Sealers

Impregnating sealers are absorbed into the pores of the granite tile and form a protective barrier that prevents liquids and stains from penetrating the stone. These sealers are typically made from silane, siloxane, or fluoropolymer, and they are invisible on the surface of the granite.

• Advantages:
  • Penetrate deep into the pores of the granite, providing long-lasting protection
  • Do not change the appearance or texture of the granite
  • Are less likely to wear off over time
• Disadvantages:
  • Can be more difficult to apply than topical sealers
  • May require multiple coats for maximum protection
  • Do not provide as much protection against scratches as topical sealers

Factors to Consider When Choosing a Sealer

When choosing a sealer for your granite tiles, there are several factors to consider, including the type of granite, the location of the tiles, and your personal preferences.

Type of Granite

As mentioned earlier, the porosity of granite can vary depending on the type of granite and how it was formed. Some types of granite are more porous than others, which means they will require a different type of sealer.

• Less Porous Granite: If your granite is less porous, you may be able to get away with using a topical sealer. These sealers provide a high level of protection against stains and scratches, and they can enhance the color and shine of the granite.
• More Porous Granite: If your granite is more porous, you will need to use an impregnating sealer. These sealers penetrate deep into the pores of the granite, providing long-lasting protection against liquids and stains.

Location of the Tiles

The location of the granite tiles is another important factor to consider when choosing a sealer. Tiles that are located in high-traffic areas or areas that are exposed to moisture will require a different type of sealer than tiles that are located in low-traffic areas.

• High-Traffic Areas: Tiles that are located in high-traffic areas, such as kitchens and bathrooms, will require a sealer that is durable and resistant to wear and tear. Topical sealers are a good choice for these areas because they provide a high level of protection against scratches and stains.
• Areas Exposed to Moisture: Tiles that are located in areas that are exposed to moisture, such as showers and swimming pools, will require a sealer that is waterproof and resistant to mold and mildew. Impregnating sealers are a good choice for these areas because they penetrate deep into the pores of the granite, providing long-lasting protection against moisture.

Personal Preferences

Your personal preferences are also an important factor to consider when choosing a sealer for your granite tiles. Some people prefer a high-gloss finish, while others prefer a matte finish. Some people also prefer a sealer that is easy to apply, while others are willing to spend more time and effort on a sealer that provides maximum protection.

Recommended Sealers for Different Types of Granite Tiles

Here are some recommended sealers for different types of granite tiles:

Ash Black Granite

Ash Black Granite is a beautiful and durable natural stone that is known for its dark color and unique pattern. This type of granite is relatively less porous, so it can be sealed with a topical sealer.

• Recommended Sealer: A high-quality acrylic or urethane topical sealer will provide a high level of protection against stains and scratches, and it will enhance the color and shine of the Ash Black Granite.

Shandong G654 Dark Grey Granite Floor

Shandong G654 Dark Grey Granite is a popular choice for flooring because of its durability and resistance to wear and tear. This type of granite is more porous than Ash Black Granite, so it will require an impregnating sealer.

• Recommended Sealer: A silane or siloxane impregnating sealer will penetrate deep into the pores of the Shandong G654 Dark Grey Granite, providing long-lasting protection against liquids and stains.

Andromeda White Granite Tiles Buy

Andromeda White Granite is a beautiful and elegant natural stone that is known for its white color and unique pattern. This type of granite is relatively less porous, so it can be sealed with a topical sealer.

• Recommended Sealer: A high-quality epoxy topical sealer will provide a high level of protection against stains and scratches, and it will enhance the color and shine of the Andromeda White Granite.

How to Apply a Granite Sealer

Once you've chosen the right sealer for your granite tiles, it's important to apply it correctly to ensure maximum protection. Here are the steps to follow when applying a granite sealer:

1. Clean the Granite Tiles: Before applying the sealer, make sure the granite tiles are clean and dry. Use a mild detergent and warm water to clean the tiles, and then rinse them thoroughly with clean water. Allow the tiles to dry completely before applying the sealer.
2. Test the Sealer: Before applying the sealer to the entire surface of the granite tiles, test it on a small, inconspicuous area to make sure it doesn't cause any discoloration or damage.
3. Apply the Sealer: Follow the instructions on the sealer container to apply the sealer to the granite tiles. Use a clean, dry cloth or a brush to apply the sealer in a thin, even layer. Make sure to cover the entire surface of the tiles, including the edges.
4. Allow the Sealer to Dry: Allow the sealer to dry completely before using the granite tiles. The drying time will depend on the type of sealer you are using and the temperature and humidity of the room.
5. Reapply the Sealer: Depending on the type of sealer you are using and the amount of traffic the granite tiles receive, you may need to reapply the sealer every 1-3 years.
