What happens here
Open the pre-mixed urethane solution and slowly inject it into the hole through the nozzle of the front disk. The foam will expand for about 20 minutes, filling the cavity and fusing to both the drywall and the backplate, creating a stronger finish than the original wall. Excess foam will come out the back, ensuring the cavity is fully filled. Once set, the front plastic piece can be removed, leaving a perfectly smooth surface that is harder than the original drywall, ready for painting or finishing without any sanding.
Goal: Fill the drywall hole with expanding foam and allow it to cure.
