Question about finishing up a fireplace grate

admin

Once the mill scale has been ground off at the weld joints and it's been welded together, what's the best way to make it all black again? It's for a customer, not personal use, otherwise I'd just start using it as it. Grill paint? Engine paint? Something else?
Reply:Do you mean a grate that holds the logs during burning?  Or something decorative?Won't matter if it's for burning in my opinion - heat will take it right off.If it's decorative - "sand" blast to an even finish and then paint is how I do smaller stuff like that.Dave J.Beware of false knowledge; it is more dangerous than ignorance. ~George Bernard Shaw~ Syncro 350Invertec v250-sThermal Arc 161 and 300MM210DialarcTried being normal once, didn't take....I think it was a Tuesday.
Reply:For presentation?  Heat it up and season it with cooking oil.
Reply:It holds the logs up. Commercial ones have some kind of finish on them, they're solid black. I thought grill or engine paint might work since they're made for heat. I don't know if oil will turn shiny back to black?
Reply:for your purpose just hit it with some high heat bbq paint. oil will keep it shiny-ish its will darken with time.
Reply:OK, thanks.
Reply:Use some hi-heat paint.  If it burns off, the metal will be heated to blue or dark gray and will blend in.  Just a way to make it less raw looking when new."USMCPOP" First-born son: KIA  Iraq 1/26/05Syncrowave 250 w/ Coolmate 3Dialarc 250, Idealarc 250SP-175 +Firepower TIG 160S (gave the TA 161 STL to the son)Lincwelder AC180C (1952)Victor & Smith O/A torchesMiller spot welder
