I am trying to recaulk bathroom tub. When I removed caulking, i found cement\ tile like material in the gap between tile and bathtub. Hardware store folks suggested me to use Henry Permixed 345 to fill the gap and caulk on top it once it dries. But I found many different solutions like using backer rod , or plumbing cement. Can you suggest what would be good option here ?Link to photos:ImgurImgurImgurImgur via /r/DIY http://ift.tt/2zXCGgG
