Introduction

Marble and granite countertops are a real find for those who appreciate style and natural beauty. They make the interior luxurious, add sophistication to any kitchen or bathroom. But, as is often the case with beautiful things, they require special care.

Anyone who has ever encountered stains on stone surfaces knows how difficult it is to remove them. Why is natural stone so susceptible to stains, and does it make sense to use special protective products? Will they help keep your marble the same as it was on the day it was installed? Let's find out!

The nature of marble and granite: why are they vulnerable?

Before understanding how to protect marble and granite, it's important to understand what makes them so vulnerable. Yes, they are natural materials, strong and durable, but their structure has its weaknesses.

Marble is a metamorphic rock composed mainly of calcite. It is characterized by a fine texture and pronounced porosity.

Marble looks like a perfect smooth surface, but deep within it are many microscopic pores. These pores are the "front door" for liquids and dirt. 

"Structure of Marble"

Granite, in turn, is an igneous rock composed of quartz, feldspar, and mica. 

Porosity of granite

It is stronger than marble and its pores are smaller, but this does not make it completely protected. Oil stains, for example, penetrate it just as easily and are almost impossible to remove without professional help.

Granite structure

What do I need to protect my stone from?

Acids: lemon, tomatoes, wine - all of these can not only leave a stain but also damage the texture.

Oils: cooking oil, creams, cosmetics. Once they penetrate the stone, the stain remains permanently.

Pigments: coffee, tea, spices - familiar problem, right?

Cleaning agents: chemicals that are too aggressive can even destroy the stone.

Now the question arises: is it possible to protect such vulnerable surfaces from all these "enemies"?

Types of protective agents for marble and granite

So, we know that a stone needs protection. But what to protect it with? The modern market offers many solutions, from traditional sealants to nanocoatings. Each of them has its own special features.

Sealants

Sealers are probably the first thing that comes to mind when it comes to stone protection. They come in two types: surface and penetrating. Let's sort out which is which. 

 

Advantages

Limitations

When to use it?

Surface sealants

  • Create a visible protective layer on the surface of the stone.
  • Prevent penetration of liquids and contaminants.
  • A sheen is often added to improve the appearance of the countertop.
  • Easy to apply, suitable for temporary protection
  • Wear out faster, especially with frequent use.
  • Can change the texture and slightly darken the color of the stone.
  • Require regular renewal (every 3-6 months).
  • For worktops with low porosity where visual effect is important (e.g. granite).
  • If you need a temporary layer of protection before a big event (like on your kitchen countertop during a party).

Penetrating sealants

  • Penetrates the pores of the stone, creating a protective barrier within the structure.
  • Do not alter the appearance of the surface.
  • Provide long-term protection (up to 1-2 years).
  • More resistant to heat, chemicals and water.
  • Can be more difficult to apply, requires careful preparation.
  • Do not protect against surface stains, scratches and external influences.


  • For porous materials such as marble, which are particularly vulnerable to liquids.
  • For long-term protection, especially on kitchen surfaces.

And if you want to maximize the effect, choose...

Combined use!

  1. Penetrating sealant closes internal pores and prevents the absorption of liquids.
  2. Surface sealant creates an additional outer layer of protection against stains, dirt and scratches.

Recommendations:

  • First apply a penetrating sealer to protect the pores of the stone.
  • After drying, apply a surface sealer to enhance exterior protection.

Ideal for:

  • Kitchen countertops that are subjected to heavy use.
  • Bathrooms where constant contact with water can weaken protection.

However, if you only have one option to choose from:

  • For granite with low porosity, a surface sealer is more suitable.
  • For marble and other porous materials, it is better to use a penetrating sealer.

! Tip: It is important to choose quality products. For example:

  • Penetrating:

And don't forget to update your coverage regularly to maintain protection!

Nanocoatings

Modern technology has made its way to the care of stone surfaces: nanocoatings have become a real breakthrough in the protection of marble and granite. They provide an invisible but incredibly effective barrier, protecting porous surfaces from dirt, water and wear.

What makes them so special? And why are more and more owners of marble and granite countertops choosing this type of protection?

What are nanocoatings?

Nanocoatings are products based on nanotechnology, where tiny particles penetrate the pores of the material and create a protective layer.

How do nanocoatings work?

Nanocoatings utilize hydrophobic and oleophobic properties that:

  1. Create a barrier: Nanoparticles penetrate and seal the pores of the stone, preventing the penetration of liquids and contaminants.
  2. Repel moisture and dirt: Thanks to their hydrophobic properties, water and oils are not absorbed, but simply roll off the surface.
  3. Reduce friction: Reduces the adhesion of dust and dirt, making the countertop easier to maintain.

These properties make nanocoatings particularly popular for kitchens where countertops are subjected to regular stress.

Advantages

Limitations

1. Superior defense:

  • Resistant to stains from grease, wine, coffee and other aggressive substances.
  • Protection from acids, such as lemon juice or vinegar, which can corrode marble.

2. Durability:

  • The service life of nanocoatings is longer than that of traditional sealants. They can retain their properties for up to 2-3 years.

3. Maintaining Appearance:

  • Completely transparent and will not alter the natural texture or luster of the stone.

4. Ease of maintenance:

  • Nanocoated surfaces require minimal maintenance as dirt is not absorbed and is easily removed.

5. eco-friendliness:

  • Many nanocoatings are toxic-free and safe for use in kitchens.

1. Price: Nanocoatings are usually more expensive than traditional sealants.

2. Difficulty of application: Proper application sometimes requires a professional approach.

3. Regularity of renewal: Although durable, the coating should still be renewed every 1-3 years, depending on the intensity of use of the surface.




How to choose a nanocoat?

When choosing, pay attention to:

  1. Purpose: Make sure that the product is suitable for marble or granite, as the properties of the stone are different.
  2. Safety: If the coating will be used in the kitchen, check that it is certified for food contact.
  3. Testimonials: Good products often have a reputation backed by positive reviews.

Polishes and waxes: for shine and care

While sealers and nanocoatings protect the stone from stains and moisture, polishes and waxes are more focused on improving its appearance and providing an extra layer of protection. They are ideal for those who want their countertops to not only be functional, but also look flawless.

What are polishes and waxes?

  • Polishes are formulations designed to restore the shine of a surface. They remove minor scratches, remove dullness and enhance light reflection, making the worktop "shine".
  • Waxes are products that create a protective layer on the surface. This layer repels water, dirt and minimizes the appearance of new minor damage.

Polishes

The polish smooths out small irregularities and scratches on the surface.

  • Creates a glossy effect that enhances the natural beauty of the stone.
  • Increases the surface's ability to reflect light, which is especially noticeable on granite.
  • When the countertop has become dull and lost its original luster.
  • After the sealant has been applied to enhance the aesthetic effect.
  • To remove minor scratches and restore the "new" look of the surface.


1. aesthetics:

  • Enhance the natural color and texture of the stone.
  • Gives the countertop a well-maintained look.

2. Additional Defense:

  • Wax reduces the risk of stains and streaks.
  • Polishes remove minor scratches and prevent them from developing further.

3. Convenience:

  • Simplify countertop maintenance.
  • Products often have an anti-static effect, which helps repel dust.
  • They don't provide deep protection like sealants do.
  • The effect of polishes and waxes is temporary and requires regular renewal.
  • Wax may not be compatible with some sealants (always read the instructions).

Waxes

  • Create a barrier on the surface, protecting it from stains and dirt.
  • Wax often has water repellent properties, which is useful in bathrooms or kitchens.
  • Simplifies cleaning: stains and streaks are easily removed from the waxed surface.
  • For extra protection over sealant.
  • If the countertop surface is exposed to frequent contact with water or food.
  • To minimize liquid and dust stains.

How to choose polish or wax?

  1. For marble:
  • Choose mild polishes that will not damage the more delicate structure of the stone.
  • Look out for low pH products such as Stone Care International Marble Polish.

  1. For granite:
  • Use polishes that enhance the shine, such as Granite Gold Polish..

  • Use polishes that enhance the shine, such as Granite Gold Polish.

Tips for using polishes and waxes

  • Surface preparation: Always clean the countertop with a mild detergent before application.
  • Application: Use a soft cloth or applicator to spread the product evenly.
  • Polishing: After application, wipe the surface with a microfiber to achieve a perfect shine.
  • Frequency: Polishes can be used once a month and waxes can be used every 2-3 months.

Polishes and waxes are more about maintenance and visual perfection than deep protection. They are ideal for maintaining the beauty of marble and granite countertops, but in tandem with sealers and nanocoatings, they give the best results.

If you want your countertops to shine and draw the eye and make maintenance easier, add polishes and waxes to your maintenance routine!

Mechanism of action of protective equipment

So how do all of these products work? Think of your countertop as a sponge. Sealants "seal" its pores so that liquids can't get in. And nanocoatings create a water- and dirt-repellent layer that keeps dirt off the surface.

What about the exterior?

Worried that the products will change the color or texture of the stone? Don't worry! Modern sealers and nanocoatings are designed to be virtually invisible.

Impact of the environment on efficiency

Do you use countertops in a kitchen where you're constantly spilling things? Or in a bathroom where the humidity is off the charts? These factors can affect the longevity of the protective layer.

  • Humidity: Protective products wear out faster in the bathroom.
  • Temperature: In the kitchen, sealants can "suffer" from heat and steam.
  • Aggressive cleaning agents: Some of them destroy even the best protective layer.
