A:  I am a Pro Handyman & have used these.. We typically use them to cover rotten laminate or wood..

It is hard to tell from your description.. Based upon what you said though, this is probably not what you need

A:  Possibly. Depends on the thickness you need to accommodate for.

A:  One was in my package.

A:  These are sold individually.
