Can this product be applied directly to a 30 year old 90% rusted galvanized chain-link fence, or must the primer be applied?
Just remove any loose rust with a wire brush and apply.

Can you spray the Hammerite through a HVLP sprayer and if so, any tips? Thinning required, tip size, pressure, etc...
Sorry I cannot. I applied to an old trailer with a brush. Worked great, however.
You could likely spray through an HVLP I used conventional spray with at about 40-45 PSI which worked very well. I used Xylene to thin with at about 10-15% & carefully prepared the surfaces. I would start with a tip for Alkyd enamels, and go from there. Consider temperature and humidity as well.
My understanding is that anything that this paint touches is un-cleanable is so we use paint brushes that we throw away and are careful not to get it on anything else.

For our application we used a 4'' smooth roller. We restored our horizontal band saw and it looked better than new.
I had an exterior metal door painted in Hammerite hammered gold a few years ago. I would like to repaint the door in Hammerite red, and want to be absolutely certain that this is possible and what I might need to do to prepare the door before repainting?
Can't say for sure about the red over gold, but I don't see why not, since Hammerite is a very heavy oil-based paint. Just make sure you apply enough coats to get complete coverage.Preparation can vary. Easiest would be to clean it thoroughly (like with TSP). Similar paints should go on over each other just fine. You do want to make sure you sand out any chipped edges, etc to prevent it from 'peeling' or cracking underneath.If you're concerned about the existing paint, ideal preparation would be to strip it - chemically (a heavy-duty paint stripper with plenty of elbow grease) or mechanically (sandpaper, sandblasting, etc.)Hope that helps.

Should be no problem unless gate is rusted.
Thank you. The existing coat is strong, but we want a color change. Pity. I think the gold looks great, even after baking in full day sun for three years. But the tenant wants a red door. Meh... As long as the two paints will adhere, there should be no problem. This is WONDERFUL paint!
I've painted over Hammerite multiple times over the years. Because of the glossy surface you might want to scuff up by sanding which would help. I use it on a trawler for the hydraulic fittings and components and just paint directly over without even sanding.The can says you can re-coat after curing but to sand.
I can tell you from personal experience that I once painted a frig with four coats of hammerite, all within about a half hour of each other. So if I were you, I'd go for it. You just may want to consider a very light sanding as I think this is considered best practices in the painting world. Just a little something to rough up the surface and make for better adhesion.
lightly sand to dull finish and then pressure wash to remove any dirt or particles. If there are rust spots, wire brush and primer with red oxide. Then apply new paint, brush, roller or spray. If you roller or spray, be sure to follow dilution recommendations for Hammerite paints. Regards.
Thanks. Excellent advice. I will scuff up the surface before repainting.
I am planning to paint a couple of old electric heaters - both made of steel. Rust is not the issue so much as I am hoping to duplicate the original finish as closely as possible. I think the hammered finish will look right. The question is: will the paint hold up with the high temperatures these heater housings may reach? Anyone use it in this sort of application?
I used the paint to paint the bench vise . In my opinion I think it would be fine, people paint radiators with latex indoor house paint all the time. hope this helps .
We love the product. We used it on the box that holds the battery for our automatic gate opener and the gate itself. It is exposed to the sun but not to extreme heat like a heater would put off. Sorry but that is all I can offer.
Thank you so much for your answer! It sounds like pretty much the same application and I have confidence now that the paint will hold up. Thank goodness Jamestown carries it! I had a very hard time locating it to purchase. Thanks to all!
I'm sorry I can not provide help in this as I have never used it in high temp applications. I would contact the manufacturer's help line.
Hi Judy, I've said the same thing about Jamestown carrying this paint. I'm so glad they do. I can't buy it locally. Best wishes with your paint project. This Hammerite paint will not disappoint you!
Hi, I've used this on baseboard cast iron heaters with no problems whatsoever, Go for it. This paint is everything they say it is and more. Wish more people knew about it.
do you guys ship to canada?
We can ship hazardous materials out of the country sorry.
hi Rick. you said you CAN, but then you said sorry. I'm a bit confused. did you mean to say that you CANNOT?
I plan to paint my metal bird bath. Would this paint withstand holding water?
Thanks for the info and the quick response.
Get a good heavy but even coat on, and as long as you don't let it freeze in winter, I believe you'll be fine. Make sure you coat with a continuous seal, especially edges, with no missed spots to let water get behind your finish.
Not recommended for under water. It is a extrior paint that does well in rain but not submerge. Hope this helps.Bruce
yes it does I painted a car with the hammeright grey water does not affect it but if it gets too thick sunlight will dull the finish and it may develop cracks
can I paint hammerite paint over a northstar urethane and be okay?
Eric Last Name
I wouldn't bet on it - This is a great product for outdoor use, chemistry the old fashion way, my guess is that has a methyl keytone base a very strong solvent. You can do the research but it probable dissolves urethane. I used it out doors on steel worked great.
I'm sorry I honestly don't know
I have used rust cap plenty . Yet all my application where with sand blasted material as needed. . I would have to say that rust cap will cover a urthane with peeling it up .
can I use a roller, as I have a rather large area to do, and cannot spray?
Yes application can be done with a roller.
My best guess is that you can use a roller even though I have only used a brush. The important thing to remember is that you can not remove this paint once it is on a surface. Plan to throw away anything used to apply it.
What does "Hammered finish" mean? I've read some of the comments here, and don't see this paint's use on a boat trailer.I need a paint for repainting my 1994 boat trailer. There is some rust, which I will sand off. It is steel--not galvanized--and is used in fresh water. I want a high gloss, automotive smooth finish. What do you recommend?Thanks.
This is the best paint for rusted areas hands down. It looks like reptile skin, lots of craggy dark lines that form a pattern in the color that looks like hammer blows. It finishes glossy but not like a smooth auto finish. Ask them to help you find the right paint.Patton, In Oregon
I used Hammerite on a metal exterior door and it worked great. It gave it a nice finish, high gloss. When the paint dries it looks like beaten metal. The door had some rust on it too, before I painted it I wire brushed the rust off. Hope this answers your question.Richard
The Hammerite Rust Cap Paint in Hammered finish is best used on rusted metal surfaces that aren't easy to remove the rust. It will not give you a shiny automotive-like finish. It dries with an uneven textured look as if you painted over metal that was hammered with a ball peen hammer--looks kind of cool but not automotive finish. I would recommend putting on two coats of an automotive epoxy primer. Then I would use an automotive urethane single stage paint. Read urethane paint instructions before use as it may require using a sealant coat over the epoxy primer (for adhesion purposes) prior to spraying the urethane single stage. Single stage urethane dries high gloss since it has clear coat mixed into it. Using two stage urethane is a bit more difficult as it requires using base coat followed by clear coat to get the glossiness. Read all data sheets and wear protective coveralls along with a good respirator. The epoxy primer gives significant protection from rust reappearing in short period of time. The urethane paint will protect the trailer from future attack from the elements better than almost anything else on the market. These paints are even available now in water-based form. Just search online.
Is the smooth aluminum paint safe for radiators?
While the paint I used was the hammered finish and not the smooth aluminum, I'm not sure I'd use it for an application subjecting it to dry heat like that. Some schools of thought claim that heating aluminum that way (for example, putting pots of water on the radiator to humidify the room during cold weather when the windows are closed) could be a form of introducing breathable aluminum into the air. This may be a contributing factor in contracting Alzheimer's. Once it painted, you're kind of stuck with it.
don't know, i used what i bought on steel. it has a chemical ingredient that would eat aluminum. sorry
Its a great product but I used it in an outdoor application on an aluminum clad building. It has a strong chemical odor so you really need to be well ventilated. That stuff is pretty flammable when wet.
Hi George, we applied this on the floors of our walk in coolers. It still looks the same as when we put it on, as long as it won't peel off due to heat, i would recommend it.
2 years later
Interior car door was rusting. Removed rust, painted with Rust Cap (hammered finish) and it has rusted through the paint 18 months year later.
One of the few Suppliers in the US where you can get Hammerite. Tough Stuff! Rust protection with no priming and hammered finish is durable and hides any surface imperfections. Highly Recommend!

Covers & dries well
I would buy this product again & again
Couldn't find this product locally. Very happy to find it at Jamestown. Perfect for painting the bed of the steel utility trailer I was building. Pricey paint but great for the job. I used it previously for many marine product painting jobs.
I built some 4" steel support structures 6 years ago. Great stuff. I am back for more.

This is the second color we have tried in the hammerite and we love it! We painted metal cabinets and most recently bare steel on a sheet metal brake stand as well as the sheet metal brake itself. Both turned out really great!
Hammerite Rust Pain
I painted my mother's old heavy rusted golf cart over 15 years ago, by just wire brushing off loose rust and it still has not rusted through. I also painted the axels on my salt water boat trailer 5 years ago, sill not rusted through. A very good paint for heavy rust.
Excellent paint to refresh a trailer
I used Hammerite to repaint an open car trailer. The metal was in good shape but rusty and the remaining paint was pretty tired. I used this product before, many years ago, for a similar purpose and the results were excellent. The paint stayed looking good for at least 5 years until I sold the trailer even though the trailer was parked outside in New England weather. This product is easy to apply but a bit messy to clean up. I decided to just use an old brush and roller and throw them away when done. I think the hannered finish is attractive for this application. I highly recommend this product for anyone who needs to repaint rusty metal to keep it looking new for a long time.
Hammerite is getting increasingly difficult to find in retail stores as Rustoleum now markets similar hammered finish paints. I am doing a restoration of something I used Hammerite on 20 years ago and am happy that Jamestown chooses to stock it. Long lasting and durable.
Turn on the fan, open the winders!
No calamities, but be most careful about how you apply it. I started with a good bristle brush and it sucked up the paint like a desert cactus; I quickly changed to a 4" trim roller (good quality) and an aluminum lasagna pan. Applying strokes quickly, darting here and there, it looks now like brushed metal. Very good results indeed. I was finished in 40 minutes with a 3' square monster Frigidaire. Trimming out the edges with a small artist's brush proved to be the best way for finishing.Then I went at the back of entrance door and a closet door. All done with 2 quarts.
