Road rash treatment

That's what I recall. It comes with instructions which are pretty good. You need to get it stuck on all around (adhesive is only around the perimeter) or some of the liquid might drip out. I think I managed to keep them on for about five days.

They don't recommend putting antibiotic cream under, as any grease that gets to where the sticky will be will stop it from adhering properly.

+1 for Tegaderm (or as it's called in our house Tigger Derm)
Sticks, stays stuck, comes off easily when done, no issues with ripping hair out if that applies to you - find an edge and roll it off slowly.
In the first day or so when it's wet go with something like a Xupad under either a conforming bandage or tubular bandage (referred to as yellow line or blue line in the trade) - assuming you're dressing a limb. The Xupad won't stick to the scabs and provides a layer of protection.
In an emergency a heavy flow sanitary towel can work as a dressing, as can a disposable nappy.

Great info!  Just recovering from a nasty front wheel slide out on green chalk a couple of weeks ago, wish I had known this then!
