Hi Guys, this will be an interesting issue because I have absolutely no experience with this. So I don't know the right phraseology to use. A few years ago we lost our home and had to move into our RV. Its a bus conversion and my husband did a quick fill in of the "ramp" to make it level with the rest of the floor and a contractor came in to install that "snap in" type of hardwood floor. At the time my husband "assumed" that they would use "self leveling" mastic to fill in the uneven spots before putting in the floor. We were desperate, pressed for time and they did not but we had no time to fix it. So now I have week spaces in the floor where there is nothing underneath. We have no money, and no ability to pull this floor up. It actually looks pretty nice. Is there something we can "inject" underneath to fill in the weak spaces? Thank you for your time, and for not making fun of me.

What do you mean by "ramp"? Pulling up a click is not that hard. Theres nothing really you can inject under it that wont stick to the floating floor.
