How to Make Latex Sealants

Fabricate your own latex sealant for repairing tires. Tire sealants are used to fix minor holes in tires or for bikes with tubeless tires. These kinds of tubeless tires are often used with mountain bikes and do not have have normal inner tubes. The tires are molded directly onto the wheel, according to Utah Mountain Biking. Latex sealant is brushed around the rim and the bead of the tire to help seal the tire and stop air from leaking out. Mix together your own sealant with just a few simple ingredients.

Instructions

    • 1

      Pour 1 cup of molding latex into a bucket. Molding latex is found at hobby and craft stores to build latex molds for sculptures.

    • 2

      Add 1 cup of automobile tire sealant to the bucket and stir with a paint stirrer or wooden spoon. This type of sealant is used to repair flat tires.

    • 3

      Pour in 1 cup of antifreeze with propylene glycol into the bucket. Choose this type over antifreeze with ethylene glycol. Propylene glycol is less toxic and your sealant may leak into the environment.

    • 4

      Add 1 cup water to the mix and stir well. It should be a thin glue-like consistency. It needs to be runny enough to brush onto the tires.

      Insert a funnel into the opening of a gallon-sized jug. Pour the homemade latex sealant inside to store.
