Neoprene is a synthetic rubber commonly used in waterproof products due to its water and oil resistance as well as its durability. Neoprene boots and waders are often used by hunters, fishermen and campers to protect their feet and legs from water and keep them warm while standing or wading in creeks, rivers and streams. If the boots get a small tear or hole, it can be repaired by using a urethane repair adhesive.
Dampen a cloth with a small amount of paint thinner or acetone nail-polish remover. Clean the area to be repaired using the dampened cloth.
Use scissors to trim away any loose threads.
Place removable adhesive tape on the inside of the neoprene boot to hold together a tear. Alternatively, if there is a hole in the boot, place the adhesive tape inside the boot, from one end of the hole to the other, until the entire hole has a thin layer of tape behind it. This will provide a backing so the repair adhesive has something to stick to and doesn't fall through the hole.
Squeeze a liberal amount of urethane repair adhesive over the tape or area to be repaired. Use a butter knife to spread the adhesive around so there is a layer even with the rest of the boot.
Keep the boot completely flat while the urethane repair adhesive dries. Most repairs take 10 to 14 hours to dry; however, for larger holes or tears, the process may take longer.
Reach inside the boot and gently remove the adhesive tape when the repair adhesive is fully dry.
If urethane repair adhesive gets stuck to your hands or any other surface, it can be removed with paint thinner or acetone-based nail-polish remover.
