I work at Six Flags Over Texas. We have a ¾ size replica of the front of the Alamo chapel at the park. It’s made out of white bead foam covered with a stucco type coating. I’ve got the job of keeping the thing repaired and it is eating me alive sometimes. The guests keep picking pieces out of the lower parts and the birds are pecking holes in the upper parts. Of course there is the damage done by the elements also. I came up with a repair goop that works out real well. I use the Liquid Nails Adhesive for Projects. That’s the blue label stuff. I put about 4 shots of the adhesive in a paper cup and add enough small gravel to make a paste. I use this to patch the holes and areas that have been damaged. It dries to a color that is close to that on the walls and is hard. The gravel gives a good texture that is close to the original. I haven’t tried using any smaller material for the texture. I guess you could use sand or finer or coarser gravel. While I was using this stuff I thought some of you might be able to get some use out of it. The really hard part of repairing the Alamo is getting to the higher parts. This takes a zoom boom. I use a 60 ft model to reach the top and along the face without moving the machine. I doubt that any of you will have to go that far though.
I used to think that “Centrifuge Salesman” was the weirdest job title I’d ever heard. “Alamo Repair Man” may have that beat.
