Re: Cracks around windows and doors
sounds like you have some structural issues. but dont quote me on that.
regarding the crack filling. you cant just use spackle as its only a light compound designed to smooth out joints. you should do the v-out method first but use sheetrock 90 for your first coat. this is what gives the joint strength. it dries much harder and stronger it will resist cracking more better than a simply skim coat compound. use the compound for your final coats to feather out the joint
fire up the saw and make some dust
