Q. Is it possible to use 3/4 plywood with a pattern embedded to stamp fresh concrete?
A. I guess anything is possible, I've never tried that. My personal opinion is, I think the plywood will be too rigid. When you tamp the plywood into the surface I think you will see the outline of the edges repeating in the surface. It will be difficult to stamp up against walls and around pipes or columns.
I'm not sure how the release agent will work with wood. You can rent rubber stamps with wood patterns if that is what you are looking for.
