How to Repair Holes in Hard Plastic

Updated March 23, 2017

Plastic is a very versatile compound that is found in many man-made objects. While plastic can be thin and pliable, hard plastic can be thick and solid as a rock. It can stand up under great stress, but, like most products, it can incur damage after time and heavy use. However, you can repair a hole in hard plastic in a process that takes less than 20 minutes to complete.

Mix Plast-aid. Wearing gloves, mix 1 part Plast-aid bonding powder to 1 part Plast-aid bonding liquid in the mixing cup provided.

Mix well for approximately 2 minutes the mixing stick provided.

Add a few drops of acrylic paint (to match the colour of the plastic you are patching) to the Plast-aid mixture and stir well.

Apply the coloured mixture to the hole in your hard plastic using your mixing stick.

Wipe away any excess mixture or mistakes with your wet hand cloth. Allow the Plast-aid to set for about 10 minutes to completely cure. Once cured, the Plast-aid compound will be as hard as the plastic, and the hole will be filled.


Do not let the Plast-aid compound sit too long before applying to the hole as it will harden stiff.
