Strippable booth coating, over already-nasty booth walls10/18/16
Hey guys, our shop never has bothered to use the strippable booth coatings to keep overspray to a minimum. The booth we have was bought used, and was neglected from the outset. We were told that the overspray already on it would make it nearly impossible to strip off the waxy coating.
I'm sorta curious though, there has to be a way other than a full 100% chemical strip, that we can surface these walls and make for a strippable surface. Some sort of glossy hard coating like an epoxy.
I would think if you sanded them down really well and applied a gloss epoxy floor coating it should work. It will take a lot of time and money however. You could always do a test on piece of scrap before you dove in all the way. Maybe applying a skin of cheap metal over the existing walls with self tapping screws would be cheaper?
Would formica be cheaper skin than sheet metal? I'm also thinking about how razor sharp the edge of sheet metal is (meaning that you should dress the exposed edges just so no one slices themselves should they walk into it or grip it the wrong way.
Rick Mosher, I can always count on a good response from you, thanks! We did think about veneering it with some sheetmetal, it's on our list of options. Not being a sheetmetal guy, I'm not sure what I'd buy, or where to get it, or what's a reasonable cost. But that's something we can find out.
Dan Shafner, I had not thought about using formica, that's probably a great idea. I'd just need to buy a gallon of the coating and spray it on some P-lam and see how easily it peels.
I know that I can buy sheet aluminum from one of my P-lam vendors, it's a popular veneer in this area for accents here-n-there. I think I even have a spare roll of it over in our offcut purgatory.
When our booth was new, the first thing we did was spray several coats of the strippable coating all over it. In time, it would start to flake and big chunks would come off. We were not happy. May have just been the particular brand we used, but we dont use it any more. Now, we simply just broom the walls as we sweep out the booth and periodically scrape with a putty knife.
JM, that's basically what we do, but our booth is smaller than most shops of our volume, because of various constraints. If we were fortunate enough to have the larger 20ft wide booths, this wouldn't be nearly the issue.
I do appreciate you sharing your experience though, thanks!
Another option would be to deftly sand blast the walls using a medium such as crushed Walnut shells. Once your down to the a bare and clean surface, the Binks booth coating is a good product. Comes in a clear or a White. Can be brushed/rolled.
As with any coating your applying , the prep work is the most important step.
we use Sherwin Williams strippable booth coating and peel down the walls once a year and the celings once every 2 - 3 years... the trick is once you have a clean surface to work with is to degrease them and then spray the coating in multiple passes up to the correct thickness.... if you don't get it thick enough it makes it ten times harder to peel off cleanly without tearing constantly... We typically use about 10-15 gallons per 20ft wide 12 ft. high 10 ft. deep booths we have....
I believe galvanized steel sheet should be available locally and not too expensive. We used to make the tops of our mixing tables out of it. It cleans up really easy.
this is how we get that stuff off the walls
