Mapei Ultralite Mortar Pro

Ultralite Mortar Pro is a professional-grade, lightweight, single-component thin-set mortar that also handles large-and-heavy-tile and nonsag applications. Ultralite Technology delivers twice the coverage of a standard thin-set mortar per pound — a 25 lb. bag covers the same area as a 50 lb bag of standard polymer-modified mortar. Less weight to carry, less product to store, same job done.

Polymer-enriched for enhanced bond performance, with a smooth, creamy consistency and Easy Glide Technology for easier spreading. Built for thicker bond coats, from 3/32" to 1/2". Contains more than 20% recycled content.

Suitable for most interior/exterior residential floor and wall installs, most interior/exterior commercial floor installs, and most interior commercial wall installs.

How does the coverage compare to a standard mortar? A 25 lb. bag of Ultralite Mortar Pro covers the same area as a 50 lb. bag of standard polymer-modified mortar — roughly double the coverage per pound.

Can this be used for large-format tile? Yes — it's formulated as a nonsag/nonslump mortar suitable for large-and-heavy-tile applications, not just standard thin-set work.

What's the difference between white and gray? Performance is identical — white is typically chosen for light, translucent, or glass tile where mortar color could show through.

How soon can I walk on it? Protect from light traffic for 24 hours, and from heavy traffic, frost, or rain for 7 days.
