Why Not Washer's?

<span style="font-size: medium;">Came across this story of a place that does real porcelain enamel coating. Nothing saddens me more than a nasty chip on an appliance. </span>

thanks for the information

I'm wondering if they would do porcelain coatings on the interior of Plastisol-covered dishwashers?!

I think you would have to remove the plastisol to give the porcelain something solid to adhere to.

 

Granted, for some dishwashers, this ISN'T a problem.

 

It would be a great way of saving an otherwise cool appliance.

Its pretty 'spensive for sure. He quotes $750 for a 42" sink!

The part to be coated will be heated to the flow temperature of glass, which means your part will be a bright red color @ ~1500 deg F. I wonder about warpage issues.

Indeed the Plastisol would have to be gone, otherwise it would just burn off!

I wonder how tough it would be to strip off the old porcelain, I should try shot blasting a washer lid sometime in our blast cabinet at work. I'm curious as then it would be possibly to epoxy powder coat the parts. Of course the powder coating isn't anywhere close to as durable as the true porcelain would be, but then again you could do all the parts of a given machine for less then $200 total... The look would be pretty similar at least.

Re-coating or otherwise Porcelain Enameling Steel

One of the problems is removing the old finish without destroying the metal, I have been told that on many old appliance parts the metal is too thin to strip with making holes in it. Another problem is warping the metal when firing, as Phil mentioned, something like a plastisol DW tank is not only very thin but the part was not engineered to withstand 1500 F so it may very likely not work.

 

For a sink, bathtub, range top, oven liner, and a washers inner basket there is no good substitute for real porcelain enamel, but for other applications when restoring an appliance Powder Coating or epoxy enamels are very good products.

How tough can the Plastisol be if it tends to separate from the base metal?

I've only had a few GE plastisol DWs that had damage. I wonder if the bond gets compromised with like a cut in the liner, down to the metal.

Once air or water get in, I wonder if that liquefies, or if the formation of rust causes separation?

What I'm trying to propose is, if one were to take a plastisol tub and soak it in XXXXXX , maybe water, would the water break the bond.

Of course if it did, the metal would rust, but, could that be treated? and than have the new finish installed.

Of course, as was mentioned earlier, the metal used for a dishwasher tub, with the Plastisol liner removed, may well be too thin for a heavy new surface material.

Would the liner then need some type reinforcement?
Like minor ribs welded or bolted on?

Frankly, If I had a plastisol DW. I would keep the control panel and front panels and mount them on a doner plastic tub machine.
