Most popular Armstrong S515 High-Performance Tile Strong Flooring Adhesive, Clear-Drying Formula is designed to meet the needs of flooring professionals. This adhesive offers strong performance on all grade levels of concrete, ceramic, terrazzo, marble, and polymeric poured floors, as well as suspended wood-delivering superior results wherever the Tile-On Installation System is approved. Its versatility makes it a practical choice for everything from commercial spaces to challenging job sites, ensuring that your installations remain secure and long-lasting.

The adhesive is moisture and alkali resistant, specifically engineered to support concrete slabs with up to 95% relative humidity, making it ideal for installations in environments prone to dampness or residual moisture. Armstrong S515 can also be used over “cutback” adhesive residue, streamlining surface preparation and minimizing downtime on the job. Its clear-drying nature allows chalk lines to stay visible beneath the adhesive, supporting precise layout and alignment throughout installation. The excellent initial grab reduces flooring tile or sheet movement, contributing to faster, more controlled application with fewer adjustments required.

This high-performance formula is suitable for a wide variety of flooring types, including RAVE, Crown Texture, Imperial Texture, MultiColor, Stonetex, Companion Square, ChromaSpin, Raffia, Feature Tile/Strips, SAFETY ZONE, Urethane No-Wax (Dry Back), and Vinyl No-Wax (Dry Back). The shelf life extends for one year when unopened, allowing for longer storage and convenient supply management. Application is completed easily by trowel, and each gallon covers a spread rate of 285-335 square feet, making it a cost-effective solution for both small and large flooring projects.
