Custom Bldg Products MTSW50 Thin Set Mortar 50 Lb White

Product Description

The CUSTOM BLDG PRODUCTS MTSW50 is a fortified thin set mortar designed for professional tile installation on floors and walls. This 50-pound bag of white Versabond mortar delivers reliable bond strength across a wide range of tile types and substrate conditions. The formula meets or exceeds ANSI A118.4 and ANSI A118.11 standards, making it suitable for demanding residential and light commercial applications. It also incorporates Moldgard technology, an integrated additive that resists mold and mildew growth within the mortar bed. Licensed tile setters and flooring contractors are the primary installers.

The MTSW50 is an all-purpose mortar suited for floor and wall tile projects in both residential and commercial settings. It performs on standard substrates including cement board, concrete, and mortar beds. The white color makes it a practical choice for installations where grout joint bleed-through is a concern, particularly with light-colored, translucent, or glass-blend tiles. Its economy formula is aimed at volume tile work where consistent performance and cost control are both priorities.

Installation Notes

Installation should be performed by a licensed tile setter or flooring contractor following TCNA Handbook guidelines and applicable local building codes. Mix mortar to a smooth, lump-free consistency and allow proper slake time before use. Apply only to clean, structurally sound substrates and verify that substrate deflection meets TCNA requirements before tiling. Do not apply over substrates with active moisture intrusion or frost.
