cast iron radiator

[MasterPlumbersKeymaster]

I have an old rad I want to keep but 60+ years of paint is tough to remove, can I have this thing sandblasted? And then what should I coat it with to keep maintenance to a minimum? Powder coating is a great idea but very costly for 1 piece.

paint with aluminum or bronze radiator paint, if you can find it. These paints reduce the efficiency of the radiators, but I have never seen such paint peel. If you use any paint, thin coats are most important.

The other way: Scrape and peel off all paint that will come off, then spray on an HHR paint that comes in an aerosol can. The HHR stands for high heat resistant, which is probably necessary with the high heat of steam radiators. It is not needed for hot water system radiators.

Do not use latex paint on a warm surface.

The latex paint and primer could develop rust spots, and latex paints may not hold their color on a hot radiator. It is better to use an oil primer (Kilz is good), and an oil-based finish paint. Actually, you could use an aerosol spray enamel as a finish coat. Of course, be careful when spraying indoors. With care and practice it is possible not to get the spray paint all over the floor, walls, and anywhere else you don’t want it.

This is how one reclaim company paints radiators. http://www.rbsoak.co.uk/cast-iron-radiators.html
One of the radiators is finished in red oxide primer, while the other two are finished in a clear powder coated lacquer.

http://www.art-restoration.com/press6.html : Years ago, when the gilding on antique mirror and picture frames became dull or darkened, the handyman of the family would visit the hardware store to buy a can of his favorite radiator paint. The choices for the “restoration” were silver or bronze. The radiator paint was great stuff. It wore well, covered the original gilding and didn’t chip. Well, here we are at the start of the twenty-first century, and those antique frames with their radiator paint finishes intact are still coming through the door of the New Orleans Conservation Guild.

you can buy J-B Weld for about five bucks at most automotive and hardware retail stores.

Go ahead & have it sandblasted that is the most cost effective method.Be prepared to pay 100-200 to have this done including priming,prime it white with a good oil base primer,for a extra 50 they should top coat it for you,with your paint you supply top coat means finished colour once again use oil base product.Never use latex on any metal surface.Powder coating is not necessary either.

Sand blasting was once a fantastic way to go BUT.

Now with the environmental agency really frowning up lead dust in the air and OSHA really upset about air borne lead particles in the work place He may be better off buying a new Radiator for about $12-$15 per section.

Did you know in this country the use of a lead based paint in an apartment can get you a fine and possible jail time.

You see in America kids eat lead paint and Lawyers love these kinds of cases as they see $$$$ from stupidity.

Sand blasting is a real no, no if not in very controlled conditions.

What is so fantastic about this Country like no other we have lawyers running industry ragged.

What these lawyers do is work for the government passing lots of laws preventing any kind of industry from working here.

Now what the other half of the government does is give tax incentives for companies to move to Mexico and other countries where lawyers are NOT allowed to stop the growth of that nation and these lawyers INVEST in over seas manufacturing plaints OK ??

SO before you suggest sand blasting find out which side of a border this person is from.

North of the border,Canada A,we are regulated about when & how to sandblast,if you are in a rural location do it out side.Let the people that run the sandblasting businesses worry about it.Oh by the way,lead paint was not used much here as we first thought when the big panic was on.Hell if all the people knew that there water services were lead then what.We have more lead pipe than paint,but no one seems to worry about the kids eating the lead bend under the toilet!
