Rubber Mat flooring questions

[Steven R]

I am ready to install my new Rubber mat flooring, My questions is when I remove the old rotted one (years ago) it had underlay under the rubber mat.

I ordered what I thought I needed but cant for the life me figure out what to do with what I received.

What I remember taking out: from the top down in layers

Rubber matting
white foam padding
Jute/carpet underlay
heavy tar like felt sound mat.

Can you tell me what order is the correct order from factory?

I have been getting info from one supplier that no under lay padding or sound felt was used. and the next supplier says the rubber floor kit comes with all the items I listed above.

Please help

Plan is to restore to factory.

any help is greatly appreciated
