The damage revealed once we got the old tiles up. No way we could put tile down on top of this stuff.
And only my sister does renovation projects in striped purple socks and fuzzy house shoes
We chiseled out some of the damaged pressboard subfloor and then pried up the long piece. We cut out the damaged part of another long board and then cut new boards to fit in the spots. After chiseling edges to fit with chisels and screwdrivers.
Today I nailed the replacement boards down, cleaned the rest and laid the new tile down
I have the edges left to do and some baseboard and threshold work and to clean some of the glue that came up between some of the tiles.
