Why I Oughta...

A week or so ago, I debuted the initial build of my (DIY) Alpine trough wasserspiel (water feature) that I created out of a Styrofoam cooler and Vinyl Concrete Patch.  I built up a few layers of the concrete patch and tried to age it/paint it to make it appear more stone-like in appearance.  On top of that, I then applied a heavy-hand of spray waterproofing.  I chose Gorilla Brand Waterproof spray.  And...it turns out....spray waterproofing (with some sort of 'solvent' in the mix that allows it to be propelled as a spray, I think??) EATS AWAY at foam.  In this case, a Styrofoam cooler.   I sprayed the waterproofing on all sides - inside and out.  And, then, I tucked it away in the garage to await the '24 hour curing period'.  My plan was to then water-test it.   When I grabbed it out of the garage, I noticed something.  One of the inside corners looked different.  It was soft and 'eaten away'.

Alpine stone trough.   But, for a prototype?  I think it will work perfectly.   The outside dimensions of the prototype are 15" long x 11" wide x 9" deep.   It has 1" thick walls.   Based on what I picked up from watching various YouTube shorts, Instagram reels and reddit posts, there are a number of ways to go about DIY'ing your own stone trough.  You can apply burlap and concrete.  You can apply something like an acrylic fortifier to try to g...
