Using the DeWalt PFC1271050 AC200+ adhesive is straightforward. First, clean the drilled holes properly with the included hole - cleaning equipment. Then, attach the mixing nozzle to the adhesive cartridge. Dispense the resin and hardener simultaneously through the mixing nozzle, which will mix them for you. Insert the threaded rod or reinforcing bar into the hole right after applying the adhesive. It starts to harden in just 3 minutes and fully cures in 30 minutes. Remember, this adhesive can be used in both dry and wet concrete, but make sure the temperature of the base material is between 23°F and 110°F. For long - term storage, keep it in a cool, dry place. If you need to use it again, simply replace the mixing nozzle. This product meets a bunch of industry standards, so you can trust its quality for your construction projects.
