Yes, you would need a sealer and probably would need to be periodically re applied, and not be scrubbable with abrasives. another important tip would be sure to use non rusting hardware, like screw, bolts, washers, etc. Otherwise you'll have rust stains running down all that pretty metal!
I have a plastic chair mat under my computer desk that the edges are curled and won't lay flat. Have been unable to bend them back as the plastic is hard
Hi Cindy!
There aren't any don'ts really but the most and biggest DO is to make sure it is securely and thoroughly waterproofed at it's seems.
*seams not seems.
A lot would depend on the application. Where it's going and how it's being used.
Functional, like plumbing, or decorative, like shelving?
