Professional-Grade Lightweight Mortar for Demanding Tile Projects

MAPEI Ultralite Mortar Pro is a high-performance, lightweight, single-component thin-set mortar designed for professional installations. Suitable for both standard thin-set applications and large-and-heavy tile, it delivers reliable bond strength with easier handling on the jobsite.

Its advanced formulation supports efficient installation while maintaining the strength and stability required for residential and commercial tile projects.

Twice the Coverage with Ultralite Technology™

Ultralite Mortar Pro incorporates MAPEI’s Ultralite Technology™, providing up to twice the coverage per pound/kg compared to a standard polymer-modified thin-set mortar. A 25-lb. bag offers the same coverage as a traditional 50-lb. mortar, improving productivity and reducing lifting strain.

Benefits include:

• Less material weight to transport and handle

• Increased jobsite efficiency

• Reduced installer fatigue

• More than 20% recycled content

This combination of performance and lightweight design makes it a smart solution for large-scale or multi-room installations.

Nonsag and Nonslump Performance for Large and Heavy Tile

Specifically engineered for large-and-heavy tile and stone, Ultralite Mortar Pro features a nonsag and nonslump formula. Wall tiles remain securely in place after setting, while floor applications maintain proper support without tile settling.

Ideal for:

• Large-format porcelain and ceramic tile

• Natural stone installations

• Wall and floor applications

• Bond coats from 3/32" to 1/2" (2.5 to 12 mm)

This stability helps ensure consistent alignment and a professional finish.

Smooth, Creamy Consistency with Easy Glide Technology™

Formulated with Easy Glide Technology™, Ultralite Mortar Pro offers smooth and creamy handling characteristics. It spreads easily, forms well-defined ridges and promotes excellent adhesive transfer to the back of the tile.

Key application advantages:

• Effortless troweling

• Strong initial grab

• Consistent coverage and bonding

These features allow installers to work efficiently while maintaining high installation standards.

Polymer-Enriched Formula for Strong, Flexible Bonding

Ultralite Mortar Pro is polymer-enriched to enhance bond performance and deformability. This added flexibility helps accommodate minor substrate movement and supports long-term durability in tile assemblies.

For contractors seeking a professional, lightweight mortar that combines strength, coverage efficiency and reliable nonsag performance, MAPEI Ultralite Mortar Pro delivers a dependable solution for modern tile installations.

MAPEI Ultralite Mortar Pro is a professional, lightweight polymer-modified thin-set mortar for large and heavy tile. It offers nonsag performance, smooth troweling and twice the coverage of standard mortars for efficient installations.
