What kind of fasteners/adhesive should I use to install laminate flooring (Pergo) over ceramic tile?

Question

I understand this is an acceptable process... However, I'm confused by how the laminate actually anchors to the tile. It makes sense that if you're putting it on wood sub-flooring you can just nail/staple, but when it's over ceramic, and I take into consideration that there's supposed to be underlayment, how does the laminate adhere? Or does it just float?

This does not get "anchored" to the existing floor underneath.  It's what's called a floating floor.  What keeps it from sliding around are a few factors.  One is the sheer weight of the whole floor once it's all assembled and connected.  The second is the rubber underlayment which is put down first before the Pergo flooring is installed.  It comes in rolls that you roll out....I suggest using duct tape every few feet on joints to keep them together and clean.  And third is the base molding that covers the 1/8" expansion gap around the outside edges of the room, or shoe molding if leaving the existing base molding in place.  Both cover up this expansion gap and ensures nothing can get between the floor and the wall to push the flooring around.  I've installed Pergo in my living room, dining room, and main hallway in my own house.  It's a good product, but my laminate flooring of choice is DuPont Real Touch.  It's already got the rubber underlayment attached to each piece of flooring so there is no need to buy the rolls of it and tape them together.  It also has a much more realistic feel and look.  It's a little more expensive than Pergo, but keep in mind there is no need to buy the rolled underlayment like you do with the Pergo which adds to the cost.  Plus the DuPont comes with an average of 35 year warranty for wear and tear.  If you are interested in the DuPont, check it out at www.homedepot.com.  I'm not a salesman nor do I work at Home Depot, just giving you some good advice from lots of experience.  Hope this all helps and good luck with your new floor.

Well Pergo is a floating floor. It doesn't get anchored down to the existing floor. It is called a floating floor because it will float with the movement of your slab/house. They are very very nice and super easy to install. All you do it put the foam/rubber lining down first and then the floor just snaps together like a puzzle. It is very easy. My husband and I just did the same thing on our slab over ceramic flooring. Good luck!! It look fabolous when everything is all done. Especially if you change your mind and dont want the pergo anymore, its really easy to just take right up.

I think there is a product called TENAX which can be useful for you. This adhesive can be used on Ceramic tiles. For other detail you can see my source site

Answer 4

Ask the people who sell Pergo.  Friends of mine just put in a beautiful Pergo floor over ceramic tiles on a slab, so I believe it's possible.  .

  Like JB said you won t anchor the floor down.. Laminate need to float and move and expand and contract. The only pieces that need to be anchored will be any transition pieces(reducers, t- molds, stairnosings and carpet bars.. Those I drill w/ a masonary bit  down thru the ceramic to wood floor and s***w to the sub floor.. And its a 1/4 inch gap to all stable places (walls cuboards etc) Using trim to cover (usually shoe  molding)    Some of the underlayment will come w/ a self stick or a way of connecting the underlayment together w/o taping   GL
