Dark Spots on FRP
What in the world?!?
Almost all of the interior of our butcher shop is polyurea on concrete. This is a tough, easily cleaned laboratory grade surface that lends itself well to the sanitation levels I want for our USDA/State inspected butcher shop.
Much more common in butcher shops is Fiberglass Reinforced Plastic (FRP) which is a pebbly wall covering you may also see in commercial bathrooms and kitchens. We have a very small amount of that behind one set of shelves in the initial cutting room (iCutter) which covers the doorway from iCutter to Cave. This provides separation between our first butchering space and the still to be finished of construction zone of the rest of the butcher shop.
Yesterday when I was finishing up some plumbing I noticed four dark round splotches on my pristine white FRP. Eek!
Can you guess how these mysterious dark circles formed? Leave answers in the comments section.
1) It wasn’t space aliens.
2) It has nothing to do with crop circles.
3) It smears away easily.
Well, that’s more than enough clues if you know my penchants for leaving something inside concrete matrices and other hidden places. Oops, that was another clue.
For bonus points, guess why I might have put what I put what I put in there that would form those circles. The clue is also in the photo if you think about how wet that room gets.
