Custom Bldg Products SDS25 Thin Set Mortar 25 Lb Gray

Product Description

The CUSTOM BLDG PRODUCTS SDS25 is a gray, polymer modified, fortified thin set mortar engineered for time-critical tile installations. It delivers accelerated set times that keep commercial and residential projects on schedule without sacrificing bond strength. The SDS25 exceeds ANSI A118.4 and ANSI A118.11 standards, making it suitable for demanding performance requirements. Moldgard Technology is built into the formula to resist mold and mildew growth after installation. Each bag weighs 25 pounds and mixes to a workable consistency for both floor and wall tile applications. Tile setters, flooring contractors, and commercial finish crews are the primary installers.

The SDS25 is designed for time-sensitive installations in high-traffic commercial environments such as restaurants, shopping malls, and hotel lobbies where downtime must be minimized. It also performs well in cold temperature conditions, making it a reliable choice for installations in unheated spaces or during cooler months. The polymer modification improves flexibility and adhesion over a range of substrates common in both new construction and remodel work.

Key Features

• Fast-setting formula suited for time-critical commercial tile installations
• Polymer modified for enhanced bond strength and flexibility
• Exceeds ANSI A118.4 and ANSI A118.11 performance standards
• Moldgard Technology resists mold and mildew growth

Compatibility

Designed as an OEM-style replacement mortar for standard thin set tile installations requiring a polymer modified, fast-setting mortar that meets ANSI A118.4 and ANSI A118.11 specifications.

Installation Notes

Installation should be performed by a qualified tile setter or flooring contractor following ANSI A108 installation standards. Mix mortar to the consistency specified on the product packaging and allow proper open time before setting tile. Substrate surfaces must be clean, flat, and free of contaminants prior to application. Avoid adding excess water during mixing, as this will reduce bond strength and extend set time.
