Bonding Agent

Definition

A substance applied to a suitable substrate to create a bond between it and a succeeding layer, such as between a subsurface and a terrazzo topping or a succeeding plaster application.

Purpose

Bonding agents are used to ensure proper adhesion between layers of materials, enhancing the structural integrity and durability of the final product. They are essential in applications where new materials need to be securely attached to existing surfaces.

Examples of Use

• Applying a bonding agent to a concrete floor before adding a terrazzo topping to ensure proper adhesion and prevent delamination.
• Using a bonding agent between old and new layers of plaster in renovation projects to achieve a seamless finish.
• Incorporating bonding agents in tile installations to improve the bond between the substrate and the tile adhesive.

Related Terms

• Adhesive: A substance used to bond materials together.
• Substrate: The underlying layer or surface to which a material is applied.
• Terrazzo: A composite material used for floor and wall treatments, consisting of chips of marble, quartz, granite, glass, or other suitable material, poured with a cementitious binder.

Notes

The choice of bonding agent depends on the materials being used and the specific application. Proper surface preparation and following manufacturer instructions are critical for achieving effective bonding.
