I wanted a DIY trellis for a grape vine against the side of my house, so I decided to make one out of 1/2" PVC pipe. Now, I fully understand that PVC does not hold paint well, but I really didn't want a white pipe trellis sticking out like a sore thumb, so I decided to give it a shot anyway. I went with something to match the brick, so I first used the Rust-Oleum Ultra Cover flat red primer (which I would call more burgundy than red), then used this Rust-Oleum Multicolor Textured Autumn Brown over that. I wanted the spotty, uneven look, like the brick, and in the instance where maybe the textured paint color was too much and not to my liking, I would lightly spot spray the primer over it, to match the old weathered brick on the house. I think it came out pretty good
I have gone through 4 cans already of this textured paint and have had zero issues, even after stopping and restarting the following day.
I can say that it does indeed have an inconsistent spray, some spots were more heavily coated than others. Again, this inconsistency was perfect for my project.
When the day comes that it need to be touched up, I can just spot spray any imperfections. Hopefully.
I have used other Rust-Oleum Textured paints on 5 gallon paint buckets that I use for gardening, both with and without primers. The paint doesn't really hold up well on those, it ends up peeling off in spots and need to be repainted every few years, more if you're picky. I fault the buckets, not the paint. Outdoor painted items are tricky to maintain.
