Need Help with Floor problem
Due to a small leak I needed to remove the subfloor under the toilet anda portion of the subfloor that runs along the bottom edge of the tub. Mybathroom is on the second floor of my condo. I have reinforced some of the joists and the old subfloor on the edge ofthe bathtub with horizontal joists (piece of wood between the new main verticaljoists and leveled them the same. The new subfloor goes on top of these horizontaljoists and can be screwed to them like the joists (screws on the edge of thetub, is that ok? (moisture)). I cut thenew subfloor and laid it down but on some sections along the tub the newsubfloor is not even with the old subfloor along the edge of the tub. Smallspaces exists because of the uneven rotten wood I removed along the bottom edgeof the tub. As a result on some sectionsyou can see the new horizontal joists that I installed underneath the oldsubfloor along the edge of the tub. What can I put between the spaces of thenew and old subfloor to make it even? (leveler type of cement, type of glue,type of rubber?)
Also, I plan to put a vinyl floor on top of the new subfloor. Once I screw down the new subfloor what typeof liquid or thin membrane can I use to help prevent future moisture from goinginto the new subfloor? Can you explainhow to install the membrane to the subfloor and then the vinyl floor?
Once all is installed what cocking is best to use for the edges of the new vinylfloor and bottom edge of the tub?
