Bostik SL-G700 Fiber™

Advanced, Fiber-Reinforced, Hybrid, Self-Smoothing & Leveling Underlayment
Where to Buy
Product overview
SL-G700 Fiber™ is an ultra fluid, fiber-reinforced self-leveling underlayment designed to create smooth, flat surfaces for the installation of finished floor coverings. Formulated for superior flow and self-smoothing performance, it can be applied from 1/8" up to 1" in a single lift, helping increase productivity compared to traditional multi-coat patching methods. Its extended working time and pour-merging characteristics help make installation easy, even for a single installer, while delivering a smooth, more consistent surface.
Suitable for floor preparation over sound concrete, wood and well-bonded VCT, SL-G700 Fiber™ can be feather-edged to meet existing elevations and creates a super-smooth substrate for sensitive floor coverings. With up to 40% greater fluidity than traditional self-leveling underlayments, it provides fast, efficient application and allows carpet, VCT, vinyl sheet goods, LVT, rubber and wood flooring to be installed in as little as 16 hours. It also contributes points toward LEED® certified projects.
