Let’s find out!
First, it’s not necessarily the color of the paint that’s messing with your paint, it’s actually the paint itself! There are several causes for this:
The color is too oxidized, causing it to stain in the absence of a buffing compound or primer.
A paint-specific solvent is used, causing it to oxidize to a state that causes color bleeding.
A product containing ammonia or ammonia-based compounds may oxidize and allow the compound to become active, causing the paint to stain.
You can find a quick look at all of these causes and more here.
When we’re painting on the Rustoleum exterior of our house, one of the most common reasons for us having to put down a layer of primer or buff is because the paint inside is already “saturated”; meaning it just does not have much color to it. While this can happen with any exterior paint, especially on our interior walls, the Rustoleum exterior can be especially difficult.
Why Rustoleum stains the interior?
Because the paint is already saturated!
Even if the paint is buffed or buffed and painted again and again, it never gets an opportunity to fully oxidize. Even if we buff, rinse, and repeat, it’s simply not going to get as much color as a fully oxidized paint, regardless of how often or how well we buff it.
Our paint is simply too rich, allowing it to oxidize in the absence of an adequate buffing compound.
Rustoleum paint is extremely rich with very little pigment: just 16.3% w/w. As a result, the paint is also too reactive, which means that even when you have a good buff, it still will not completely protect your paint from oxidization. Since most of the Rustoleum paint on the outside comes out to a high level of redness, the exterior doesn’t even look the same.
How often should you paint on your Rustoleum exterior?
This depends on the specific paint that you’re painting on. If you need to add another coat of paint on top of what’s already there, you need to buff it off very carefully; otherwise, you will have to repeat buffing as you go along until the paint is completely completely dry, so your paint is a lot more prone to being damaged than a fully oxidized paint would be.
