Question Floating laminate over carpet

I want to install a non-glued laminate floor over an existing carpeted floor in my kitchen. There is no way for me to remove the carpet because it was glued down to the concrete slab. There was no padding installed under the carpeting and the carpet is a very low nape indoor/outdoor berber type carpeting(about an 1/8" thickness). I checked the floor and it is level throughout. Can I install a laminate floor over this existing carpeted floor without any reprecussions later down the road?

The below notes were copied from Armstrongs website.

Carpet
 Fully adhered, 1/4″ (6.35 mm) or less, carpet over a suspended wood subfloor is a suitable substrate.
 All other carpet and any carpet pad must be removed. If the carpet was
glued in place, remove all remaining debris and excessive adhesive residue.
Do not install laminate over carpet adhered to concrete.
 Two-in-One Underlayment is not recommended.
 Use clear polyethylene plastic over the carpet. The seams do not need to
be taped.

just be sure to check the manufacturer's specifications for the flooring that you purchase. you don't want to invalidate your warranty by installing incorrectly.

Since this is over concrete, NO!!!

Had it been over wood with adiquate crawl space height, then you could do it.


Trapping a gluedown carpet between a moist concrete substrate and a plastic moisture barrier, is asking for trouble. MOLD is just one problem.

Thanks for replying. So you're telling me that because the existing carpet is glued to the concrete foundation floor I will in fact develop a mold problem underneath the laminate even though I have never had any moisture problems in the past. Is my only option to remove the carpet or not put a laminate floor down at all?!

Remove the gluedown carpet or pay the price later, when your removing the laminate and the carpet, while wearing a respirator.

Gluedown carpet is removed every day. On concrete makes it easier, then if this was wood, it was attached to.


Kitchen floor with carpet... There is all kind of food, to feed a good mold colony in that carpet!!! All concrete has moisture vapor emissions. Not much air circulation under there is it? No UV light source to kill a mold colony, either The formula is there all it takes is one spore... Let this be the last warning, and then your on your own!!!

Laminate flooring over concrete requires a vapor retarder. Carpet over concrete must be removed as indicated. Then, install manufacturer's recommended vapor retarder and proceed according to manufacturer's instructions for installation.

I appreciate the advise and respect your input. I will in fact remove the carpet from the concrete floor before installing a laminate. I know I may have sounded stubborn but I was just looking for an easier way of putting in a new floor. Understand that I am somewhat ignorant to putting in a new floor and that is why I got on this site. I think my name speaks for itself. Thanks very much for your help !!

Remove as much as you can by hand and then you can rent a concrete floor sander from HD. This will help in removing the left over material from the concrete.

Wear a mask...it will be very dusty.
