How to Use Super Glue Accelerator for Stronger Bonds

Learn how to use super glue accelerator (CA accelerator) to instantly cure cyanoacrylate glue, improve gap-filling, and create stronger bonds on plastics and wood.
Quick Answer
Apply super glue to the joint, then add a drop of liquid accelerator like Zap Zip Kicker to force an instant cure. This method bridges gaps, bonds end grain, and works safely on most plastics.
Why Use an Accelerator?
Cyanoacrylate (CA) glue sets when it reacts with moisture in the air, but that can take 10–30 seconds or longer on non-porous surfaces. An accelerator forces an immediate cure, which prevents the glue from wicking away or running into unwanted areas. It also expands the glue's gap-filling capacity, making it ideal for joints that don't fit perfectly or for end-grain gluing where the glue tends to soak in.
When Not to Use Accelerator
Accelerator can cause CA glue to set so fast that you lose repositioning time. If you need to slide parts into alignment, skip the accelerator or apply it only after the parts are exactly where you want them. Also, some accelerators produce a white bloom (frosting) on glossy surfaces; test on a scrap piece first.
How to Use Super Glue Accelerator
- Step 1: Prepare the Joint: Make sure the surfaces are clean, dry, and free of dust or grease. For end grain or porous wood, apply a thin coat of CA glue first and let it soak in for a few seconds before adding more glue. Common mistake: applying accelerator before the glue is in place, which causes the glue to skin over and fail to bond.
- Step 2: Apply the Super Glue: Put a small drop or thin bead of cyanoacrylate glue on one surface. Press the parts together and hold for a moment. Do not use too much glue — accelerator works best with a thin, even layer. Checkpoint: If the joint has a visible gap, add a little extra glue so the accelerator can expand and fill the void.
- Step 3: Apply the Accelerator: Place one drop of liquid accelerator (like Zap Zip Kicker) directly onto the glue line. The glue will set instantly — within one second. For larger areas, use a fine mist spray or apply with a brush. Common mistake: using too much accelerator can cause the glue to foam or become brittle. One drop per inch of glue line is usually enough.
- Step 4: Allow Full Cure (Optional): The bond is strong enough to handle light stress immediately, but for maximum strength, wait 10–15 minutes before sanding, drilling, or applying heavy load.
