Default Prepping a BLACKTOP surface?

Hey guys, I'm fortunate enough to have a basketball court with the hoops removed in my complex and I'm looking to set up a track on it!

I need to know some of the prep steps needed to make it ready...

The blacktop has no cracks, will need to power wash it but what should i spray over the lanes?


Thanks for the input!

Daryl

sugar water

mix 5# powdered sugar to 5 gallons of water, spray on the lanes.

you can also use grape soda, which ever would be cheaper.

I guess the ants will be great for drifting over LOL.

Sorry all I can think of is a race track of dead ants.

Ants usually are not a problem as the asphalt is too hot for them. But if your worried just hose off the track at the end of the day...doesn't take long to wash it away.

Also depending on what cars you'll be running you might just want to try power washing it and trying it without a spray. Touring cars may get enough grip without it. Sure grip will be better with a spray but it might not be needed. But if you are going to run foam tire cars like pan cars you'll need a spray.

Good day!

We use pop and ants are not a problem but near the end of the season wasps are. We get hundreds of dopey wasps on the track and they do get in the cars.

We use cheap grape soda. Works well.

No matter what you choose, someone will not be happy.

nobody mentioned CLEANING the surface First

If you have water available - Blow it off (dirt and dust) and wash it too if possible...

Depending on how you lay the track out - adjust what/where you spray (I usually go heavy on corner exits, and light on entrances... and AS NEEDED on straights.

Root beer was alway my choice, but grape soda and sugar water were good too. (root beer has enough fizz to drill a hole in the lid to spray - but a hudson sprayer still works best.)

A leaf blower would save you a lot of time.

Our facility is right between a bulk materials handling area for a concrete mixing plant and a dirt offroad track. No matter what way the wind blows, we get sand and grit all over the track all week, and sometimes throughout the race day.

We use a high power backpack leaf blower to blow off the track before we spray is with soda. We have found that a smooth, even coat all over the track works best to even out traction. That way if some cars get together anywhere on the track or anyone gets off of the race line, you never have to worry about a variable surface. Doesn't really matter as much through the straights, but there's NOTHING worse than variable traction through all sections of a turn.

Soda/sugar water prep works because it's sticky/tacky and pulls rubber from the tires and collects the shed/worn off rubber and sticks it to the track. It's that subsequent rubber-on-rubber action that builds traction, especially as the day goes on and the track gets hotter. To a point, wherever you spray more prep, you're going to build more traction faster, less prep lower traction. That's why traction builds so fast in the corners where there's the most scrub and rubber laid down. It's also why the groove turns a darker color.

Be careful not to spray too much sugar water/soda prep, though, as the humidity level could make the track slimy and slick instead of tacky throughout the day. We mix 70% soda and 30% water and do 3-5 thin even coats. I'd start with two coats and see if you need more. Depending on the size of your track overall, you'll probably want to have each coat dry before adding the next.

The downside of cheap and easy is that if the humidity level comes up before you lay down a good base of rubber groove, sugar water/soda prep'd tracks will get slimy and slick as the prep rehydrates.

power wash the whole surface first, then put down your layout. Spray with grape soda (.99 cents for 2 litres) then rinse it all away end of race day.

Dont forget an air compressor to clean off the cars after every run. To many tracks forget this!
