I'm trying to finish my basement and plan to use Metal Studs. Can anyone recommend a dealer in the Plymouth area. Both Lowes and HD are no longer stocking them? Also, I planned to use DryLok to seal the foundation (poured concrete) but some tell me that this prevent the concrete from breathing and can cause failure? That seems extreme but I dont want to create other problems. I also plan to use rigid foam board Insl. so I dont know if sealing the foundation is necessary. Any advice.
