Sto BTS® Plus

Sto BTS® Plus is an advanced, one-component, polymer-modified, cement-based dry powder ideal for use as both an adhesive and a base coat in Sto Wall Claddings, including StoTherm® ci and StoTherm® ci Mineral Systems. Here’s why Sto BTS® Plus stands out in the construction industry:

• High Performance and Versatility: Designed to achieve a minimum of 1/16" base coat thickness in a single application, Sto BTS® Plus simplifies installation processes and ensures robust coverage across various substrates.
• Enhanced Durability: With its high polymer-to-cement ratio, Sto BTS® Plus offers increased flexural strength, significantly reducing the risk of cracking and improving the longevity of the wall systems.
• Labor Efficiency: The product's ability to be applied up to 1/16" thickness in one go, along with its creamy, smooth consistency, allows for quicker, more efficient application, enhancing job site productivity.
• Environmental and Safety Features: Sto BTS® Plus is vapor permeable, allowing substrates to breathe and thus preventing issues like blisters caused by trapped vapor. It’s also formulated with factory-blended Portland cement for consistent performance, and its low cement ratio reduces efflorescence and free lime content.
• Ease of Use: Ready to mix with water on the job site, Sto BTS® Plus is packed in 47 lb. bags, facilitating handling and storage, while its bagged powder form reduces solid waste compared to pails.

Sto BTS® Plus is designed for professionals looking for a reliable, high-quality solution that provides both adhesive and coating functions, ensuring durability and ease of use in building façade applications.

Sto BTS® Plus coverage details are as follows:

• As an Adhesive Over Sheathing and Smooth Masonry: Covers approximately 90-135 square feet (8.4-12.5 square meters) per bag, when applied with a 1/2" x 1/2" U-notched trowel.
• As an Adhesive Over Rough or Uneven Masonry: Provides coverage of about 30-45 square feet (2.8-4.2 square meters) per bag, when applied with a 5/8" x 5/8" square-notched trowel.
• As a Base Coat: Extends coverage over approximately 80-125 square feet (7.4-11.6 square meters) per bag.
