We have an older plant, with a concrete floor and concrete block construction.
The interior walls were painted a long time ago, and now it is peeling. We know we need to do something...we're just not sure what the best approach would be.
My boss has a friend in the food industry who recently visited a plant where they had NO paint...bare walls, even unpainted equipment! That seemed strange to me...
The interior walls are somewhat porous...the concrete block was not skim-coated or anything, so it has the normal pits and crevices. I don't think it would be considered adequate to leave it unpainted or uncoated in some way...but what would work best?
We want something that will not require maintenance...or, at least, minimal maintenance. If possible, it could even be the same thing we could put on our floor (though we don't know if we really need to do the floor...it's smooth, no cracks that I know of at this time).
Any thoughts? Suggestions? Products/processes to avoid?
