Application Instructions
-
Preparation: The surface must be 100% clean, dry, and free of dust. Because the mastic is transparent, any dirt left behind will be visible through the glue.
-
Mixing: Use a clean, non-porous surface for mixing. Add 1% to 2% of the liquid hardener to the paste. Mix thoroughly until the catalyst is fully dispersed.
-
Note: Using too much hardener can cause the product to become brittle or slightly tinted.
-
-
Application: Apply the mixture immediately with a clean spatula. You have a working window of about 5 minutes.
-
Finishing: Once the mastic is rock-hard, scrape off any excess. Sand the area with fine-grit abrasives and finish with a polishing compound to achieve a seamless, invisible repair.
