How bond Sign Locators to ACM Sign Letters (SnapFix & SimpleFix)

Learn how to bond SnapFix & SimpleFix Locators to Aluminium Composite (aka ACM) for installing flat cut sign letters.

 

Follow these simple steps to securely bond Snapfix or Simplefix locators to your Acrylic flat cut letters using Stykra 360 adhesive.

What you’ll need:

Step 1. Remove the protective film
Peel off the film from your acrylic letter.

Pro tip: Mark the locator positions on your letter during CNC machining. This allows you to create exact replacement letters in the future with perfectly matching locator positions.

Step 2. Position the locators
Place a male locator stud next to each marked location on the back of the letter to check spacing and fit.

Step 3. Apply Stykra 360 adhesive
Apply a small amount of Stykra 360 next to each locator position.

Important: Only apply adhesive to a few locations at a time and insert the locator immediately — the adhesive starts curing quickly.

Step 4. Allow initial cure time for handling
Allow 4-5 minutes for the adhesive to cure enough for safe handling.

Step 5. Wait before installation
Full bond strength is achieved after 24 hours. So we recommend waiting the full 24 hrs before installing your letters.
