Painting new (Galvanized) pellet pipe.

[imacman]

Just got most of my Simpson Dura Vent pipe in over the weekend, and want to start painting. I had heard about some problems w/ paint flaking off, and know that galvanized needs to be "pickled". Usually white vinegar wiped on it, let to sit a few minutes, and rinsed off should do the trick, but I wanted to know for sure from the "horses mouth", so I sent an email to Simpson, and this is what they said:

"Rinse the pipe with water that has a little vinegar in it to remove any residual oils from the manufacturing process. Because we do not make the paint we would recommend that you follow the directions on the paint to complete the process."


Thanks

The vinegar will work well. So does windex. I think the biggest cause of stove paint flaking is usually improper curing.

Finger nail polish remover works the best

Any type of degreaser works great.

Fingernail polish is just diluted and perfumed Acetone.

You can buy straight Acetone at any good hardware store.

Acetone is an excellent degreaser. Use outside or well ventilated and away from sparks/ignition source.

Yes, all those solvents will remove the grease or oil that's on the surface, but the vinegar actually does that PLUS it is a mild acid, which etches the surface to give the paint something to grip onto.

I'll stick w/ what the MFR. recommends, and what I thought was correct in the first place....besides, what else am I going to do w/ a gallon of vinegar? :lol:

Thanks for the suggestions everyone.

I would clean it with Lacquer thinner, scuff with 320 grit paper, wipe clean, hang the pipe on a pole suspended on the ends with rope, put a few dust coats let tack off then hit it with a wet coat. if you want let dry and repeat.

I washed it off with dish soap and water, and dried thoroughly. Then I 3 coated it with Rustoleum High Heat paint. So far so good.

im actually looking to do this as well, im sure all you need to do is get all the greasy substance off the pipes then get some barbecue grill spray

should work fine

I know I'm a noob here but please be careful using acid on galvanized anything. The zinc coating will be removed and if fumes are generated it will be highly toxic to you. Welders refer to it as metal fume fever and can kill. Just FYI.

Yes hydrochloric acid will dissolve zinc. I do it almost every day at work as a coating weight test to measure the zinc coating on steel strip. And I have had metal fume fever from welding galvinized, no fun at all.
