Adhesives for Natural Stone

What Are Natural Stone Adhesives?

Natural stone adhesives are specialized bonding products designed to provide a strong and durable connection between stone slabs and various surfaces. These adhesives are formulated to withstand the weight of the stone, prevent cracking, and ensure resistance to weather conditions and mechanical stress.

Why Do You Need Specialized Stone Adhesives?

Natural stone, such as marble, granite, limestone, and travertine, has unique structure, weight, and porosity. Standard adhesives may not be strong enough or durable to provide a long-lasting bond. Specialized stone adhesives offer:

✔ Exceptional adhesion – Creates a strong bond between the stone and substrate.
✔ Weather resistance – Suitable for both indoor and outdoor applications.
✔ Flexibility – Allows for slight movements of the stone without causing cracks.
✔ Water & frost resistance – Essential for outdoor use and moist areas.

Types of Adhesives for Natural Stone

1. Cement-Based Adhesives

Cement-based adhesives are a versatile choice for installing natural stone. They are cement-based with added polymers to enhance adhesion and elasticity. These adhesives provide high strength and are widely used for various applications.

Features:

✔ High resistance to heavy loads.
✔ Suitable for both interior and exterior applications.
✔ Ideal for flooring and wall cladding.

How to Choose the Right Adhesive for Natural Stone?

✔ Stone Type:

• Heavier stones (e.g., granite & marble) require high-strength adhesives.
• Porous stones (e.g., limestone & travertine) need penetrating adhesives.

✔ Substrate Type:

• Concrete or cement-based surfaces → Use cement-based adhesives (Strom 21).
• Non-traditional surfaces (e.g., metal or glass) → Use polymer-based adhesives (Soudal).

✔ Application:

• Indoor projects → Both cement & polymer adhesives are suitable.
• Outdoor use → Select adhesives with high resistance to water & frost.

Installation Process for Natural Stone

1. Surface Preparation

✔ Cleaning: Ensure the substrate is clean, dry, and free from grease.
✔ Leveling: Make sure the surface is even and crack-free.

2. Adhesive Preparation

✔ Cement Adhesives: Mix with water according to manufacturer instructions until achieving a homogeneous mixture.
✔ Polymer Adhesives: Ready to use, no mixing required.

3. Adhesive Application

✔ Tool: Use a notched trowel for even distribution.
✔ Layer: Apply adhesive on the substrate and an additional thin layer on the stone's backside for better adhesion.

4. Stone Installation

✔ Press the stone slab onto the adhesive, ensuring even contact.
✔ Use a level to ensure proper alignment.

5. Grouting

✔ Once the adhesive fully dries (24-48 hours), grout the joints for added stability & aesthetics.
