If you glue the bamboo directly to the vinyl flooring and anything should ever cause the vinyl to turn loose, you would lose your bamboo also. My advice is to float the bamboo or remove the vinyl and glue the bamboo.

The ability to lay vinyl over plywood is down to the construction of the home. Often times the plywood is sitting on wood joists. This is not the case with wood floors. Many people install wood directly over concrete slabs. Slabs have issues with moisture. The wood floors allow some of the moisture to move off. If you lay vinyl over the wood you are them 'capping' the wood so that the little bit of moisture no longer escapes. The moisture droplets hit the bottom of the vinyl and drop DOWN onto the wood. The wood then soaks up the moisture over top. The wood absorbs it. The finish becomes soft and then ruptures and the wood continues to rot. I do not know if you are on concrete slab or if you are over plywood subfloor on wood joists. If you are on wood joists you *might be be able to pull this off (might). If you MUST cover up your hardwood I HIGHLY RECOMMEND you sand OFF the finish. It will cost about $2/sf to sand it down (assuming it is NOT a factory finish). Now you have raw wood. And that raw wood can be considered a 'like for like' situation as plywood. But now you are 1/2 way to a sand/refinish. If you install the Coretec over the sanded hardwood, you will have a more expensive situation than if you had simply done a full sand and refinish. Just for fun, how about you check your door jambs (interior and exterior doors) as well as your baseboards and your floor height differences when changing from CoreTec to another flooring surface. If you are putting this in the kitchen as well, you might find you have issues with appliances and counter top clearances (like the dishwasher) or built-in fridges.

I have the Home Depot Lifeproof LPV being put down now. It is a beautiful chevron design in light color wood grain. We are half way though and I want to rip it out. It looks gorgeous and that is the only good thing. The fake wood grooves hold dust and grit. I vacuumed, swept, swiffered mopped and mopped again and finally on hands and knees washed and dried the floor and if you run a hand over it there is still dust and grit. Also, I kept hearing about the good sound quality in a room compared to other hard floors and that it was not as cold as tile. BS on that too. I gave the installers a day off on a Friday hoping I would feel better about it in a few days. Nope. I feel like a fool. I spent almost $10,000 and even though it is gorgeous, I hate how cold it is and the grit just will not go away. I am in such a quandary. It was very difficult to prep the house for the installation. While it would be financially foolish, it may be better to ditch it now. Very said here in Colorado.

Thanks so much for the detailed advice, @SJ McCarthy! I do have 3 extra boxes and then some, and so far pulling them up isn't seeming too difficult to do but I'm sure we'll run into some issues :-) The condo rules aren't very specific: 80% of floors must be carpet or area rugs - we have carpet in the bedrooms and someone on the board told me that LVP with an underlay is fine; this one has a pre-attached pad. But thanks for brining it up - I do want to run it by them once more to be sure before we totally finalize things. When you say "a little grinding PLUS a little leveling compound" are you referring to self leveling compound? It does seem to me that SL would be the best way to easily get a good level. We've worked with some patching material (Henry 345) on a few spots, and it has the appeal of potentially being simpler than SL up front (doesn't have to be mixed and doesn't require primer), but it's more expensive for covering a given area, and doesn't level itself. I'm still trying to figure out if we can reasonably apply self leveler to just a portion of the room, and I'm thinking mainly that will require that there is indeed a consistent "low" spot / sink so that the SL doesn't run out into the areas we don't want to repair. That does seem to be the case, but I need to really spend the time with a level to fully map it out. Thanks again!
