Rustoleum is NOT a rustic rustic. When we say that rustolum stop rust we mean the same thing we mean when we say that we stopped rust in a piece of iron . The rustoleum is not a substitute for rust. The rustyness is not gone, it is in fact present in the rustolum and still there, the rustoleum is much more rust resistant, it resists rust more than the iron, the iron did not have to be “rust-free”. However, even with the most resistant rustoleum, there will be places where rust will creep in and when these spots are covered with a regular coating of rust, then those spots will be covered again.
Do rustoleum coats rust pipes?
Yes, most rustoleum is porous and that allows a small amount of rust to go through. The problem with the porous nature is that as you put on a thicker coat, the holes between the layers of dust get larger and larger, and if you remove the top coat before the holes get large enough (about 1/4 inch or smaller) the rust will “come through”. However, it won’t “come out”, it will just go away over the next years or years. The bottom line is that if you buy rustoleum that is too thick or too thin for this type of thing, you are asking for some serious problems. The reason for this is that with a porous surface, dust particles are more likely to get trapped under the dust and so there are far less dust particles that can actually “come through”, when they do, they will go through the pores and get trapped in the pores. So, even the thickest that you can get (about 4-6 inches) does not stop all rust completely.
Do black rustoleum and brown rustoleum make rust?
No, they do not make rust. Any type of rust that is not covered by rustoleum is not “mold”. Mold is a microscopic cloud formed on the inside of a thin sheet of metal. Molds will form on many other materials as well, in fact you will notice that the types of materials you buy will vary from batch to batch.
Why don’t I see any rust on my “moldy” or “rusted” materials?
If there is a rust-free part that is exposed to mold, that part is often coated with some kind of dust or “moldy” treatment. But
