Bond Coat

Definition

A material used between the back of the tile and the prepared surface. Suitable bond coats include pure Portland cement, Dry-Set Portland cement mortar, latex-type Portland cement mortar, organic adhesive, and the like.

Purpose

Examples of Use

• Applying a bond coat of Dry-Set Portland cement mortar when installing ceramic tiles on a bathroom floor.
• Using a latex-type Portland cement mortar bond coat for outdoor tile applications to accommodate slight movement and prevent cracks.
• Installing tiles on a kitchen backsplash with an organic adhesive bond coat to ensure secure attachment to the wall.

Related Terms

• Portland Cement: A common type of cement used in various construction applications for its strength and durability.

Notes

Selecting the appropriate bond coat material based on the specific tile type and environmental conditions is crucial for a successful installation. Proper surface preparation and application techniques also play a key role in achieving effective bonding.
