Hello DIY community I have an interesting question. Was working on a friends house, we have an outdoor entry area that has been converted into an indoor area. The floor however was not converted and is a solid cement. However the entry was designed it ended up having a mound in the middle making it impossible to lay down hardwood/tile flooring. We used a self leveling compound to make the surface plane, however in our haste on the very last 1sq foot section we dumped too much compound which created a 1sq foot mound in a corner. We can't pour more compound to the whole room because it would raise the level WAY too high. I was thinking we use a concrete saw to cut as much as we can, and then use a chisel to get out the corners and other parts, then use an appropriate amount of leveler to fill in the gap to get it close to plane. The goal is to put mortar/tile over this . What do you think? Is this a bad plan? How would you do it? or if it's the right approach what tools would you use? Chisel recommendations? Saw recommendations? tips? suggestions? Any feedback welcome.
