SF-8™ Spray Foam Adhesive is a strong and durable 8-minute tack-free polyurethane adhesive. This adhesive is easy to use with a wide range of construction and hardscape materials, works fast, and provides optimal coverage. Highly recommended for use with retaining wall blocks and caps. Materials are fully cured within 24 hours. Application time is up to 50% faster than conventional tube adhesives. One can of SF-8™ will replace 20+ traditional tubes of adhesive. One can of SF-8™ can produce 600 linear feet with a 3/8” bead, or approximately the length of two football fields. When using with the SF-8™ dispenser gun you can expect an easy and precise application. SF-8™ Cleaner is essential for use of SF-8™ Adhesive. SF-8™ Cleaner clears out the SF-8™ Dispenser with a pull of a trigger. It can also be used with the attached spray nozzle for spot cleaning on the job as well. Also included will be three SF-8 t-shirts in various sizes.
