Thank you for your very detailed reply however I am a little confused by it. Are you saying that as I am covering up the OSB with backer board (1/4' thick cement Wonder Board) that it is OK? I had origially not intended to put anything between the subfloor and the backer board because of all the warnings about OSB coming apart when it became damp but when I checked the surface there were some elevation differences (1/8-1/4")at the joints of two pieces of the OSB. I had wanted some epoxy or some filler to pour into these low areas so that the backer board would have support and not be spanning a hollow about 5ftx1ft, 1/4" deep.
The OSB is in good shape and this hollow is from poor workmanship not damage. |
