The Bostik Findley Group has produced an installation video/DVD for its SL-150 self-leveling underlayment. The video provides comprehensive, step-by-step instructions for installing the underlayment, whether with hand tools or a pump. SL-150 is engineered to deliver an extended flow/heal time of 20 minutes and high compressive strengths averaging 1,500 pounds per square inch after four hours, and leading to 5,500 psi after 28 days, Bostik says.
