Paint question...

[Richard]

I have this JCB industrial backhoe. The paint on it ....... in a word, is pathetic.

That said "I don't care" as I'm not worried about it looking pretty.... just functional.

Current situation: One of my stabilizers for the hoe is starting to leak. This was last rebuilt maybe 15/18 years ago. I don't really know when it was done other than "right before" I bought it (and I don't remember how long I've had it!!!)

So I've decided to rebuild the cylinder. I just did the dipper-stick cylinder a couple months ago so I now have the process down.

The paint over the years has faded so no matter what I do, it's not going to match.

My concern is less about matching but rather WHAT paint do I want to use? Also I suppose, what primer?

I don't really care if these were painted red, yellow, black or green (just not pink please) so my real concern is trying to find a paint that might be fairly durable. Also, I can spray it if that helps.

Years ago when I had a larger cylinder redone (by the dealer) they sprayed something yellow on it but, this paint seemed to still be "sticky" LONG afterwards. I'm guessing it was some kind of oil.

I don't claim to be an expert painter, but for equipment I would go with Rustoleum. It is readily available and is quite durable once it cures. The downside is that it takes a month or more to fully harden, but if you can be careful that long, it gets very hard. If it has a good paint surface, I would just sand it and final coat it. If the paint is peeling or there is rust, I would use the clean metal primer. I've also used the automotive type isocynate paints with hardeners and they provide a great surface with immediate hardness. However, it's a lot of work and you need to have a breathing air system, so it just isn't worth it for equipment.

The sticky paint was probably due to poor surface prep and there being oil on the surface prior to painting. I would use an economical mid shelf paint such as Rust-Oleum. If you use a can you could mix in hardner to make it more durable.
I love the Rustoleum self etching primer. It really adheres nicely to metal.

Well...."Shazam" as Gomer Pyle once (once??) said....

I wouldn't have thought of Rus-Oleum..... Probably a lot easier than pulling out the air compressor to spray it on.

Sprayed on Rustoleum or XO-rust works great with a little hardener added

To achieve an actual quality finish, would require you to spend hundreds of dollars on materials, that all have a learning curve you will then need to overcome.

Your best options is to, as mentioned, do it with industrial enamel, (i.e. Rustoleum, or similar spray cans).

Industrial enamel can remain "tacky" if it is mixed improperly, or applied to heavy.

Industrial enamel is inexpensive, so the solvents used in it are poor quality. Applying heavy coats, without allowing the solvents to "flash", (evaporate), between coats traps these solvents inside the film, and that keeps it from curing. Until all the solvents evaporate, paint will not reach any level of hardness.

This can be avoided by following the label directions. Don't be in a hurry. Wait between coats for the paint to start to set up, and you minimize the amount of solvent in the finished film. Allow several weeks in the sun, or someplace warm, for the film to achieve full cure, (hardness).

Actually the old formula Rustoleum will remain tacky for days if not sprayed and left in the hot sun in 70+ degree weather. Best have a fairly dust free inside location to store items painted with it if you are concerned about appearance.

I have used the Rustoleum and Majic brand implement paints. They both fade with the Majic brand fading much faster.

I don't know how well the Krylon implement paint holds up but it takes 6 cans to cover the same as 1 can of any other brand and will run before you can say don't do it.

Lest you go to an automotive paint store and pay for quality products your options are all a compromise. But then yellow construction type equipment isn't supposed to be pretty. My NH Backhoe sure isn't.

The most durable machinery paint I have found is sold at CAT dealers.
Has a CAT label, but is made by Sherwin Williams I believe.
NOT crazy expensive either!
Good stuff!

I painted both of my dump truck beds with Rustoleum earlier this year. I didn’t spray it I just rolled it on and it actually looks pretty good. And it’s held up pretty good. It’s far from a classic car grade work but it’s a dump truck and it looks way better than it did. I think the same process would be plenty good enough for an old backhoe.

Since I know NOTHING about this type of painting.....

Question: Could I use that POR paint (and/or it's prep stuff).... and once it dries, take some yellow Rust Oleum and give it the yellow color?
