Step 1 - Dry The Area Well
Clean your toilet but PRO Tip; avoid using chemical products at this stage because this can affect step 3.
Step 2 - Peel The Backing
Pull off the adhesive backing (thin red/black film).
Step 3 - Stick & Press HARD
Stick the patch just above the water line for the best results. PRESS HARD ALL OVER THE PATCH.
Step 4 - Ready, Aim, Fire
The Target has been set, time to test it. You can expect the patch to stay stuck from anywhere between 1 month and 12 months depending on flush strength, temp, chemical use, and scrubbing.
