I found that I did not fill the repair to the appropriate level or height. Can I add more putty to the repair to fix the void that was created?
It is recommended that you lightly sand the surface, rid of dust. Mix a small quantity of liquid A and liquid B. Apply to surface. Knead appropriate amount of putty A and putty B. Apply to liquid surface and allow to set up. It is recommended to wait 24 hours before sanding.
