I'm preparing to do a small bathroom with marmoleum. The floor is completely out of whack and I need to use a good flooring leveler to help take out some of the voids. I want something with good adhesion and good smoothing characteristics. What would you consider to be one of the better products out on the market for me to use? This is only a small 10 by 10 bathroom so its not a really large job. The homeowner isn't that interested in it having to be perfectly level but I want it close because I don't want a call back if it starts to lift. the bathroom is located in the basement and is only for guests.
