Really need more information too. What brand of self level, how deep and how big of an area are you talking.
Thanks for the quick responses. I don't have a self leveling compound in mind at this point, I just know there are a couple low spots that would need to be leveled. I'd be guessing at this point since I have the floor covered with a cheap laminate right now, but don't believe the low spots are more than 3/8" in about a 5 sq. ft. area. Otherwise the rest of the floor was quite flat.
I've been reading about removing the cutback and heard various tips such as just trying hot water, and other cutback removers including Bean-e-doo (soy bean based). So I'm also weighing this option vs. sealing the cutback. 2 years ago I pulled up the carpet to temporarily throw down a cheap laminate until we were ready to put down some nice hardwood (now), and this is when I found the thin vinyl tiles below. They came up super easy and left behind a very thin layer of cutback. In the photo below you'll see an area near the corner where the cutback looks like it was removed. I believe this area actually had water damage from a broken pipe from the previous owners, which leads me to believe that hot water might be a viable solution.
Assuming self leveling compound will be needed in a couple of places (most of the floor was flat otherwise), at this point I'm trying to decide:
* Remove cutback with hot water/cutback remover, or seal with sureseal?
* Install glue down tongue and groove, or float click lock?
I'll have a pro do the leveling and install, but it looks like I'm stuck solving the cutback issue.
Appreciate your feedback.
Photo of cutback, note this had just ben mopped with water so it was still shiny:
