Pre-applied adhesive works great on properly prepared surfaces. If your product isn't sticking well, the surface likely needs additional preparation. Here's how to get a lasting bond.
Surface Preparation (Critical!)
1. Clean Thoroughly
Wipe the mounting surface with:
- 50/50 mix of isopropyl alcohol and water, OR
- A degreaser like Simple Green
Let it dry completely before applying.
2. Scuff Smooth/Glossy Surfaces
Plastic fenders and smooth surfaces need texture for adhesive to grip:
- Lightly sand with 220-grit sandpaper
- Clean again after sanding to remove dust
3. Ensure Proper Temperature
- Apply at room temperature (65-75°F / 18-24°C)
- Cold temperatures reduce adhesive effectiveness
- If the product was shipped in cold weather, let it warm up first
4. Apply Firm Pressure
Press firmly across the entire surface for 30+ seconds. Adhesive bonds strengthen over 24-72 hours.
Alternative Mounting Methods
For maximum durability, many customers use:
- Automotive 3M double-sided tape – Stronger than standard adhesive
- Small screws or rivets – Permanent mechanical fastening
- Contact cement or super glue – For rubber-to-plastic bonds
If Adhesive Has Failed
If the adhesive backing has delaminated or was defective from the start (not a surface prep issue), contact us with your order number for a replacement.
Pro Tip
For items like mud flaps that experience vibration and weather, mechanical fasteners (screws or rivets) combined with adhesive provide the most reliable long-term hold.
