NO!!!! Your cement board needs to be thin set down & screwed or stapled the moisture in the mud will blow up the Laminate,The job would look good for about month then your slate would jump off the floor

The laminate is real easy to remove
all you do is remove the base or trim use a skillsaw to make couple of cuts, the rest will come right up in pieces remove the pad. If the floor is concrete you dont need backer board
good luck !

one tip: seal your slate once before you grout makes for easy clean up

NO! The laminate is a floating wood floor, and you want your cement board firmly screwed to the subfloor. You will need to remove the laminate floor. Sorry.

Yes is the simple answer.

I recently put laminate in our home… we had vinyl down, and went right over top of it with the foam underlayment and a floating floor. The floor is quieter than when we had the vinyl only.

good luck!

I just did hardwood floors a few months ago and they sold me a fiber underlay that seems to do a good job of reducing noise. See the link below for the stuff I used.

Fortunately, hardwood manufacturers have kept pace with demand to provide appropriate products for installation in condominiums, with their concrete “sub floors”. There are a number of products to choose from, besides solid wood parquet, which is glued down. There are also laminated products, built like plywood, with a few layers of wood running in different directions, then with a solid wood (say oak, but could be other species). Some are meant to be glued down, while others “float”, which means the tongue and groove is glued together on each panel, to hold the floor together, but otherwise is just sitting on the concrete floor. There is a foam pad which is to be used under these floors. (Some versions of this floor do not require gluing the tongue and groove together, but have special joints that click lock each panel to the next and can be disassembled. In the case of reduction of sound transmission, it is very effective to install cork sheeting first.The cork could be installed with a quick dry parquet adhesive for floating floors. It should be rolled with a weighted roller to make sure of good grab between the cork/floor and the adhesive.

recently worked in a luxury home and the home owner decided on a rubber material that could be put under the hardwood floors

In all seriousness, walking on the floor with bare feet, socks, slippers or sneakers is the kindest thing you can do for the people below. Even with cork, sound will transfer (although lessened) if wearing hard soled shoes.

In most condos cork is required under any hard surface as in wood flooring. Also area rugs on top finish the room. Use 1/4″ cork. Will cost about $1 for the cork and about $ .35 for the glue for the cork, per sq. ft.

Alcohol will do it.
