Roberts 6399 Pressure Sensitive Adhesive — LVT LVP VCT Flooring Glue
The Roberts 6399 Firm Set Transitional Pressure Sensitive Adhesive is a high-performance acrylic adhesive engineered for demanding flooring installations in both residential and commercial environments. Designed to deliver strong initial tack and long-term durability, it provides exceptional resistance to lateral movement and rolling loads, making it ideal for high-traffic areas.
This versatile adhesive supports installation of a wide range of flooring materials, including luxury vinyl tile (LVT), luxury vinyl plank (LVP), vinyl composition tile (VCT), vinyl sheet goods, carpet tile, and stair treads. It is also suitable for cushion-to-substrate applications.
Roberts 6399 offers flexible installation methods. When used as a pressure-sensitive adhesive, it provides up to 60 minutes of open time and up to 12 hours of working time. For semi-wet installation, it offers a 20-minute open time and 40-minute working time. As the adhesive cures, it transitions into a firm, permanent bond, combining ease of installation with long-term performance.
Compatible with a wide range of substrates including concrete, primed gypsum, cement backerboard, plywood, OSB, terrazzo, ceramic tile, and properly prepared existing flooring, it delivers reliable bonding across diverse applications. The adhesive also performs well over radiant-heated floors up to 85°F (30°C).
Enhanced with Microban antimicrobial protection, Roberts 6399 helps prevent the growth of odor- and stain-causing bacteria. Its low VOC content, FloorScore, and CRI certifications make it a safe and environmentally responsible choice for indoor use.
