I would not. The wood has to expand and contract with temp changes. Your floor will buckle if you do.
yes
The foam pads used for laminates are often moisture barrier's. By not allowing the moisture from the concrete anywhere to go, it will trap it with the wood parquet. Wet wood swells and will cause the laminate to fail. For this reason, laminate should not be laid on top of parquet which is on a concrete subfloor.
laminate floor is floating, ie it is hooked to itself and is not attached to subfloor - wood flooring is nailed to subfloor, usually thru the tongue .. you must then finish the wood flooring, and laminate already has its finish..
depends on the substrate, what you're installing the flooring on. You can glue it down if on concrete, nail it down if on wood, or even float it if on either.
There are a few different ways to level your subfloor to make it ready for vinyl or linoleum flooring - depending on what kind of subfloor you have, and how much leveling has to be done. If your subfloor is concrete, and is smooth and in good shape, you need put nothing down first - install your linoleum right to the concrete. If your concrete has cracks or even major areas of unevenness, you can apply a concrete leveling compound (trowel it smooth, or pour a self-leveling variety). Then flooring on top of that. If your subfloor is wood, you'll need an underlayment. Most folks use 1/4"-5/16" wood underlayment designed for flooring, but a better option would be 1/4" tile backerboard (it's moisture resistant and won't rot like wood will). You can also apply the same sort of leveling compound I mentioned above, and trowel or pour that to your subfloor. With compound or underlayment, either way, once the floor is smooth and even, you're ready for flooring.
it has to be tacky!!!!!!!
Absolutely.
The ability to glue down a floor is not dependent on the species of wood. Rather, it depends on the construction of the wood and the condition of the subfloor. If your wood is solid, you should nail it and not glue it, regardless of species. If it's engineered hardwood and if your surface is clear smooth then you can glue it. Bamboo is the one exception. Technically, the solid bamboo is considered solid, but it is constructed like an engineered product, so can glue solid bamboo down (you can also nail it into plywood, as well as float it). Also, you usually see in the box, the manufacturer's recommendation on how you can install, if it is a prefinished product.
You'll need wood glue to install any sort of bamboo flooring.
Should take one day if there is no problems with your subfloor.
Wood glue can be used to bond flooring but the end result will be very poor. For only a few dollars more a proper bonding product can be used.
There is no specific hardwood flooring glue as it's not supposed to be glued down. You could glue it with a good quality wood glue, but most manufacturers warn that this can cause buckling later on. It's generally angle nailed.
Most manufactures do not recommend installing solid wood onto concrete.
