What stone adhesive should we choose to achieve the desired strength and finish?

These are some of the questions that arise when choosing the correct stone adhesive for bonding materials such as marble, porcelain, granite, ceramic, or quartz agglomerate. Fillers and resins are among the most demanded products by marble workers or sculptors, who use them daily. The most sought-after chemical characteristic in these adhesives is that they acquire the properties of stone, such as hardness and color, once they have hardened.

STONE ADHESIVE FORMATS

The formats in which these adhesives are available depend greatly on their composition, use, and application. On one hand, there are liquid adhesives, and on the other hand, there are solid adhesives available in formats such as fillers, paste, or silicone.

Within these two divisions, we can distinguish between:

Monocomponent adhesives, which do not require the addition of a catalyst for hardening.

Bicomponent adhesives, which do require a catalyst. This mixture creates hardening and a finish similar to that of the stone.

Catalysis is a process by which the speed of a chemical reaction is increased with the involvement of a substance called a catalyst. The use of a catalyst accelerates the hardening of the stone adhesive.

TYPES OF STONE ADHESIVES

Different chemical formulas of stone adhesives can be found on the market, including fillers, silicones, resins, pastes, and adhesives.

Epoxy: This is an epoxy or polyepoxide adhesive for stone, which is a thermosetting polymer that hardens when mixed with a catalyst or hardener.

Polyurethane: These adhesives are based on isocyanate. They are characterized by being elastic during application and rigid after drying, providing great resistance.

Polyester: The chemical base of this adhesive is elastomer, which is known for its flexibility and transparency.

Catalyst: This is the chemical component required by certain stone adhesives to accelerate the hardening process. It adds hardness without altering the final appearance.

APPLICATION OF ADHESIVES IN INTERIOR AND EXTERIOR SETTINGS

VERTICAL APPLICATION FOR WALLS OR HORIZONTAL APPLICATION FOR COUNTERTOPS AND TILES

When choosing a stone adhesive, the first consideration should be the location where the pieces to be joined will be placed.

• For vertical applications, such as wall cladding, fillers are recommended because they allow for molding. 
• For horizontal applications, such as joining countertops, liquid adhesives or glues are more manageable and fill the pores.

Most adhesives on the market can withstand normal humidity and temperature conditions. However, in many cases, the cladding will be exposed to extreme situations, requiring a more specific adhesive. In such cases, epoxy-based and polyester-based adhesives are most suitable as they can withstand high thermal expansions and elevated humidity.

TRANSPARENT OR COLORED FILLERS FOR STONE RESTORATION

MARBLE, TRAVERTINE, PORCELAIN, QUARTZ, GRANITE

Another element to consider is the type of joint finish, whether visible or hidden, gaps, etc. Currently, there is a wide variety of products available, allowing you to find the color that best matches the stone.

• For restoration work, transparent products are most convenient as they blend in seamlessly, offering a clean, transparent, and colorless bond that guarantees a less noticeable result.
•  This type of transparent filler is commonly used on travertine marble to fill the characteristic voids.
• A solid-colored mixture is perfect for porcelain, quartz, or granite if you want the joint to be inconspicuous. After application, it can be polished like regular stone, resulting in a flawless natural shine and transparency.
