If the laminate has underlay already attached to the tiles, can you still use another underlay underneath that?

Hi There,

It is better to remove the laminate and install new ones. It could cause mold issues.

If you are asking if you should remove any old underlay that is inplace now then yes you should remove it. The laminate with its own underlay attatched is an easier one to use as all you do is put them together and there is no need for any other underlay.

One thing you need to watch for is the thickness of your lamanite as it a can range from 7 to 12 mils. So pick one that fits your plans for your floor coverings.

You could still use another underlay if the Laminate that you are installing has one attached to it. It is not necessary and may cause to laminate floor to have a "springy' or bouncy effect when you walk on it.

Thank you for your replies.

Roger your answer was what I was thinking. The springy feeling underfoot.

Thank you,

Hi there,

I am thinking you are buying the Costco laminate that has the underlay already on it. You can still put another underlay, but remember that it raises your flooring up that much more and can affect your doors closing over the floor etc.

I had a client ask me to install another underlay beneath the laminate with the attached underlay (it was for a basement and she wanted extra insulation) and things worked out fine. She bought a basic Rona brand underlay to put on first, then the Costco laminate. She is still happy with the floor and no issues have come up.

In the rest of the house I would say it is unnecessary, the attached underlay should be sufficient.

In my professional opinion I wouldnt recommend doing that because the seems in the laminate will flex too much aka they will have to much play, which will in turn pop the seems.. There is no need to lay anymore underlay down.

If you want more comfort inmpact insulation value-simply lay down a 3 in one underlay, then install new laminate tile over it.

Yes, there is no problem at all in placing another underlay.
