Use a 1/2" plastic putty knife to apply the mixture to the outside of your trash can.

If the surface of your trash can is extremely smooth, sand the area around the damage before applying the mixture to allow it to adhere better to the surface.

This mixture will begin to harden within 3 to 4 minutes, so work as fast as you can to get an even layer on the surface.

Allow the mixture to cure on your trash can for at least 30 minutes.
