Thank you for posting your feedback . We are sorry to see your low star review on Phenopatch Wallboard Joint Compound. This product is designed for filling holes, cracks, dents and cosmetic defects on drywall. When installing fasteners as an anchor point/mechanical connection, especially in a weight bearing applications, the use of two-part epoxy-based fillers such as DAP Tank Bond Heavy Duty Advanced Epoxy would be recommended.
