CUSTOM introduces Natural Stone and Large Tile Mortar

To better reflect its versatile application, CUSTOM released its newly renamed Natural Stone and Large Title Mortar, previously known as Marble, Granite and Travertine mortar. This premium product is part of CUSTOM’s family of modified dry-set mortars for large and heavy tile.

The product renaming comes in response to the industry trend toward larger size field tiles. While Natural Stone and Large Tile Mortar was first conceived to specifically address the unique installation challenges of natural stone, the new name more clearly communicates its capabilities to hold and support a wider variety of tile products on vertical and horizontal surfaces. The mortar is engineered to support the weight of large and heavy ceramic or porcelain tile measuring 15 inches or greater on one or more sides, as well as all natural stone tiles that are inherently heavier. It can also be used with clay pavers and other thin- or medium-bed applications.

“Tile sizes have changed. Today, we see larger tiles, such as 12 inches by 24 inches, and plank shape tiles in a variety of lengths from 24 inches to 48 inches, that require a different type of mortar. CUSTOM’s Natural Stone and Large Tile Mortar offers premium performance for the installations of these tiles with non-slump support for flat, even floor installations and non-sag/non-slip properties for wall installations,” says Eric Carr, director of product and channel marketing — construction.

CUSTOM’s Natural Stone and Large Tile Mortar is available in white or gray and is eligible for up to a lifetime warranty when used with a qualifying CUSTOM system of surface preparation and grout products. It exceeds ANSI A118.4 and A118.11 standards without the need for additives.
