Premium Polymer-Modified Mortar for Large and Heavy Tile

MAPEI Ultraflex LFT is a premium, polymer-enriched mortar specifically formulated for installing large-format and heavy tile and stone. With a high content of unique dry polymer, it delivers exceptional adhesion to both substrate and tile, ensuring a secure and long-lasting bond.

Ideal for interior and exterior applications, this mortar supports professional installations on floors, walls, and countertops in residential and commercial settings.

Nonsag and Nonslump Stability for Precision Installation

Ultraflex LFT is engineered with a nonsag formula for vertical surfaces and nonslump performance for floors. This dual capability allows installers to confidently set large and heavy tiles without worrying about shifting, sagging, or uneven alignment.

• Nonsag performance for wall installations

• Nonslump support for floor applications

• Designed for large-format porcelain, ceramic, and natural stone

This stability helps maintain clean lines and consistent spacing throughout the project.

Thicker Bond Coats for Enhanced Support and Coverage

Designed for bond coats ranging from 3/32" to 1/2" (2.5 to 12 mm) after embedment, Ultraflex LFT provides added support beneath large tiles. The ability to build up thicker layers helps compensate for minor substrate irregularities while maintaining full mortar coverage.

• Supports large and heavy tile installations

• Helps improve coverage under oversized tiles

• Promotes strong, durable adhesion

This makes it an excellent solution for today’s trend toward larger tile formats.

Easy Glide Technology™ for Smooth, Creamy Application

Formulated with Easy Glide Technology™, Ultraflex LFT offers a smooth and creamy consistency that enhances workability and reduces installer fatigue. The mortar spreads easily, allowing for faster application and improved trowel control.

• Smooth consistency for easy handling

• Excellent transfer to tile and substrate

• Improves efficiency on large installations

The enhanced workability contributes to professional-quality results on every job.

Environmentally Conscious, Low-Emission Performance

Ultraflex LFT features very low volatile organic compound (VOC) emissions and includes an offset of greenhouse gas emissions. This makes it a responsible choice for projects that prioritize indoor air quality and sustainable construction practices.

• Very low VOC formulation

• Supports environmentally conscious building

• Suitable for residential and commercial interiors

This combination of performance and sustainability makes it a modern solution for advanced tile installations.
