Filling holes in plastic is a common household repair task that can be accomplished with a variety of materials and techniques. The most important factor to consider when choosing a method is the type of plastic involved. Different plastics have different properties, so it is important to use a filler that is compatible with the plastic you are repairing.
One of the most common methods for filling holes in plastic is to use a two-part epoxy. Epoxy is a strong, durable adhesive that can be used to bond a variety of materials, including plastic. To use epoxy, simply mix the two parts together and apply it to the hole. Allow the epoxy to cure for the amount of time specified on the package.
