Adhesives

Tile adhesive bonds tile or flooring to an installation surface. Common options include thinset mortar, mastic and wood flooring adhesive; the right choice depends on the material, location, moisture exposure and installation requirements. 

Benefits of Choosing the Right Adhesive

• Creates a strong, lasting bond
• Supports different tile and flooring materials
• Meets the needs of wet or dry applications
• Accommodates specialized installations such as heated floors
• Helps reduce installation problems over time 

Types of Tile Adhesive

Best Tile Adhesives by Application

• Showers: Thinset mortar is commonly used for shower walls and floors because it provides strong adhesion and moisture resistance.
• Kitchens: Thinset works for many floors and backsplashes; mastic may be appropriate for dry interior backsplash applications with limited water exposure.
• Porcelain and natural stone: Thinset provides a strong bond for dense or heavy materials such as porcelain, marble, travertine and slate.
• Heated floors: Modified thinset can provide added flexibility as temperatures change. Verify compatibility with the radiant heating system. 
   

How to Choose Tile Adhesive

Consider these factors when selecting an adhesive:

1. Material: Match the adhesive to porcelain, ceramic, natural stone, wood or other flooring.
2. Moisture: Choose an adhesive approved for the expected wet or dry conditions.
3. Application: Consider floors versus walls and interior versus exterior installations.
4. Movement: Account for temperature changes, heated floors or other movement.
5. Color: Consider white thinset for light-colored tile or grout and gray for darker finishes when appropriate.
