Can I paint a walk-in cooler?
A discussion started in 2006 and continuing through 2017 . . .(2006)
Q. I own a couple of pizza restaurants called Papa Joe's Pizza and would like to paint the aluminum walk-in cooler the colors of the high school next door. I actually messed up the walls of the cooler by thinking they were stainless steel and used oven cleaner--ouch--black mess! The school colors idea is just a cover up (no pun intended)! So I really need some help. No bad weather conditions to worry about.Mama Joe

A. None of us can answer that. Should you, probably. How to: Go to a real paint store and get a primer made for aluminum. Wash the cooler with an abrasive pad (not steel wool) with a little TSP [trisodium phosphate [linked by editor to product info at Amazon]] from a wallpaper store. Rinse, dry, prime and paint. Make sure that the primer and the paint are compatible. Spray is optimal. If you roll, use a short nap roller.James Watts

A. You can paint the inside of your cooler. first you need to check with your local health codes and make a decision from there. To paint it you would use a moisture cured urethane and a similar product for another finish coat. On the other hand if health codes will not permit that, they do change from location to location, you can go in and lightly sand all corners and walls install and install rfp covering. RFP will pass just about all health codes nationally.James Finley

Q. How does one tell if the construction is galvanized steel or aluminum and is there a difference in what kind of paint to use for a walk in cooler according to what construction material used.Bob Burns

A. Hi, Bob.
A magnet will quickly reveal whether the metal is aluminum or steel. While the ideal treatment for aluminum involves chromates, these are not suitable for a food location anyway, and a galvanized primer should be fine for aluminum as well. Good luck.

White spots in Walk-In CoolerApril 21, 2017
Q. I sometimes clean walk-in coolers for customers. I notice that there are whitish looking spots on the surface before and after cleaning. Is this an indication that the manufacturer's finish is wearing off? And is there a way to get it all looking like new again? Is there a clear coating you can spray on or what?James wright
