Teardrops n Tiny Travel Trailers

Some use a roller with spike to puncture the foam.

Where do you get them what are the exact Name?

The metal one I purchased is a wallpaper removal tool. I got one years ago through amazon. Its likely found in most hardware stores
and wallpaper providers.

There are now also plastic spiked rollers for use with self leveling compounds.

Ok thanks I will take a look.
The only thing I found was pizza roller.
