Many years ago they painted the lins on the old Dominguez track, and it turned out the paint was very slippery. I don't remember what paint they used, but I think Brad House may have been involved and he might know. You might also try the Encino people, as they redid their track a while ago.
Found this on Yahoo. Having raced Friday nights to see and feel the effects of what was test applied, it would be nice to see the whole oval rehabilitated. So I did some googling around the net and found this.
There are some products mentioned in the links that you might agree with. Check 'em out? (It applies to tennis courts but my brain is telling me there are shared goals between tennis and track cycling when it comes to grip.)
Most of those funky textured finishes may give a lot of apparent grip but they also make the track very slow. And as they wear they become expensive to maintain.
You want a basic concrete industrial paint, preferably a sprayed on one. These come in two varieties, waterproof and not. The waterproof ones are smooth and protect the concrete a bit better, but you generally don't need that kind of protection on a track surface and they make it extremely slippery with even a little moisture like dew in the morning. These paints are typically epoxies (the better versions are, anyway) and can last many seasons. Refinishing often requires sandblasting the surface just to etch it enough so the new paint sticks properly, but it's not a bad problem. Hope that helps.

When we rebuilt Northbrook in 2004, we sealed it using the same material used on tennis courts. Kenosha is also sealed with the same material.
This product was developed to be the topcoat / sealant for asphalt sports surfaces.
This product allows you to adjust the amount of "grip' by adjusting the amount of sand incorporated into the mix. But a word of warning: Adding a bit more sand to increase grip sounds like a good idea, however, it will be more abrasive on the skin.
If you want a track that's remotely fast, don't go to sand or adhesion additives. You get the characteristics you want from the paint itself. It just has to be the right paint. There are specialty paints made for this kind of application.
You guys actually believe, or have seen scientific proof, that your tires rolling on the line for a brief second is going to slow you down? Like, a textured paint is going to cause that drastic of increase in rolling resistance, compared to the concrete or asphalt, for the second or so you're on the line, to noticeably slow your speed?
On a concrete track, even a painted line with sand grit in it, it still going to be slightly smoother than the actual surface.
Most important is not having the lines be too glossy slick. Worrying about the lines making the track "slow" is not really an issue.
To properly prep and paint concrete, it's best to first strip any old paint and degrease the area that's going to be painted. It's preferred to use a concrete etch prior to painting as well, to insure the best adhesion into the concrete surface.
