Removing shop primer from home

[canwesteng]

Not sure if this is allowed - I've picked up some scrap steel from a fabricator to make a pizza steel at home. I thought I could just sand the shop primer off to get to bare metal given how easy it nicks on site, and it's how I've cleaned steel before, but no luck by hand. Does anyone have any suggestions? Palm sander, wire brush on a grinder, or pay someone to blast it?

I would think that 'blasting' it would be the most effective, else maybe a wire wheel and hand grinder.

Since you'll be using the steel in heat, why not burn the paint off?

My preferred method is 5" angle grinder with STRIPPER DISC. Link

Less painful than wire wheel 'shrapnel' hitting you in the belly etc.

noxious or toxic fumes...

I've torched old paint off metals, even solid wood post (not recommended as it fires up the wood). But I wonder the primer can be burned clean without sanding, or other mechanical/chemical methods. Just curious.

Thee are some nice "safe" strippers out there these days. This one works well, if not especially fast.

The problem with sloppy work is that the supply FAR EXCEEDS the demand

canwesteng - If you choose to do this yourself, will be a good idea to review the Material Data Safety Sheets (MSDS) for typical shop primers. With this info you will be able to determine what personal protective equipment (PPE) should be used. A few are listed:

Tnemec Shop Primer

Sherwin-Williams Shopcoat Primer - Gray

Sherwin-Williams Shopcoat Primer - Red Oxide

Rust-oleum Shop Coat Primer

I don't know about shop coat, but in the USA Tnemec brand coatings are frequently considered the "standard" for heavy industry.
