Slime is useless against pinch flats (cinder blocks, logs, etc.), but when you get right down to it, so are tubeless tires. Slime works pretty well for punctures, though, which are sometimes encountered when riding in the desert. Slimes also work better at cold temperatures because there's less air in a tire and it takes more force to push out the block or pin.
The best way to deal with a flat is to have some form of emergency repair equipment on your bike. This could be a tube, a patch, or some special tools for removing a road hazard. In the event that you have no repair materials on you, there are several things you can do to help avoid needing a new tire. The first thing you should do is check the front and rear tires for any signs of damage. If one or both of them has an open hole, then this could be caused by a nail or other sharp object that was thrown up at you during traffic.
If all else fails, you can use slime to fix a puncture. First, remove any loose objects that may have fallen into the hole such as small rocks or dirt. Next, soak a cotton ball in white glue and place it in the hole. Let the glue dry for about five minutes and then fill the hole with water. This will expand the glue and seal the tire.
4.0 stars out of 5 A less expensive alternative to an expired OEM flat tire kit. Slime is an excellent technique to repair a flat tire without harming the rim. It's simple to use, thanks to the dual-purpose cap that unscrews the valve stem and also closes off the empty bottle, preventing a mess in your car. The sealing compound inside the tube will keep air from leaking out while it sets, and will also help prevent dirt from entering the hole where the valve stem used to be.
Slime works by mixing two ingredients: polyurea resin and calcium carbonate. You'll need a bottle with a tight-fitting lid that can hold both ingredients and has no metal parts that could contaminate the mixture. Before you start, make sure there are no cracks or holes in the tire's surface. If there is, the fluid may leak out during setting.
After opening the bottle, mix the two ingredients by inverting it several times or shaking it vigorously. Apply the mixture to the damaged area using a clean finger. Make sure to apply it to both sides of the hole to provide maximum protection against water penetration. Let it set for at least 30 minutes before going back on the road.
Once set, slime will not peel off like tape does. However, you should still remove any hardened material that forms around the hole after setting because it can cut off your blood supply if it remains inside the tire when it re-inflates.
Slime is most known for its green tire sealant, which is made up of fibers, binders, and patented clogging agents that clump together and tangle to seal punctures in inner tubes and tires. The fibers come from wood pulp or cotton and the binder can be natural rubber or synthetic resin. The clumping agents include finely ground metal oxides such as zinc oxide or aluminum oxide.
Tire sludge is the name given to any type of glue used to repair tires. It's different from normal mud because it's sticky when dry and solidifies into a hard material when it gets wet.
The two main types of tire sludge are green and black. Green sludge is made of natural rubber proteins and contains small amounts of zinc oxide and other additives. Black sludge is made of synthetic resins and lacks any additives. Both types of sludge are used to patch holes in tires so they can be reused.
In addition to being used as tire patches, sludges can also be sprayed onto grass or pavement to form a non-skid surface. This is called turf sealing and is done by lawn care companies who specialize in this type of work.
Tire sludge is not toxic but it does contain chemicals that can leach out of the sludge if it gets wet.
