what form of calcium is mixed in, or how is it applied?

just looking for some insight, thanks!

I have had some experience in BMX racing with Calcium Cloride. This is a common chemical for pool maintenance. It firms up the clay/sand mix and will reduce the amount of weeds that grow. I don't know about abrasive surface content but it was the way to go to control grass and firm up the surface.

comes in a bag, pool supply should have it, I've seen guys spread it with a one pound coffee can, then water it in two days before the mains, wash your hands after spreading cause it will eat you!!!

makes the surface hard as concrete, surface will blue groove > a little or a lot depends on how many racers run on it

watch the track, IF white areas develop sprites lightly those areas, IF you over water you will lose the blue groove

depends on the track, water one foot either side of the line pipes and when you blow the track the dust will stick

blow (shallow angle) the dust off as needed BUT don't blow to hard (steep angle) the surface may come up

It works fairly well for firming up the track and allowing a groove to come in for a trophy event. Follow the tips above.

Best not to run a wet track with the stuff, since when the stuff mixes with water and covers your car it will start rusting by the time you get through post-tech or marshalling it seems!

Here is what our track looks like when we use the stuff.

Tubaboy, how much Cal. chloride are you using? I can either get flakes in a 50# bag or liquid. I've tried it and it really doesn't do much, probly didn't use enough. For those who want to use calcium chloride try to find a chemical supply outlet vs. the pool supplier, probly much cheaper. I can pay $60 for 250# of flakes. Don't know what others have paid.
FYI calcium chloride in my area is actually used to control dust on gravel roads, (Wisconsin). It actually pulls moisture from the air and keeps the dirt "wet".

Any other ways ,

That year our track was 100'x70'. It was approximately 110 gallons premixed from an oil drilling company, where they donated the left overs to us. Sorry I don't know the ratio.

We also use soda syrup periodically. It works well, but tends to chunk up a bit easier. Just make sure not to use diet or sugar free syrups! That's like putting water on your track. If you live where there are a lot of bees I have heard issues. Here in the Wyoming desert we don't have that issue. For syrup, water the track, dump the syrup on the track and brush it in.

Sugar & water also work well. ARCOR down in New Mexico uses that setup for their track. Brush it into the dirt dry, then water the track. Result is that popcorn sticky feeling at the theater.
