How to Use Double-Sided Carpet Tile Tape to Secure Outdoor Stair Solar Lights

June 4, 2025

Installing solar lights on outdoor stairs can transform the safety and ambiance of your home’s exterior. But mounting these lights securely—especially to materials like concrete, Trex, TimberTech, or Fiberon decking—can be tricky without drilling holes or using messy adhesives.

That’s where extreme-strength double-sided carpet tile tape comes in. Originally engineered for high-traffic commercial flooring, this tape is now being discovered as a surprisingly effective mounting solution for outdoor solar stair lights.

Why Use Carpet Tile Tape for Outdoor Solar Lights?

Most solar lights come with basic screws or flimsy double-stick pads. These fail quickly when exposed to the elements—or require drilling into composite or concrete stairs, which is messy, risky, and permanent.

High-performance carpet tile tape offers a better solution. Designed to secure flooring in gyms, basements, offices, churches, daycares, and event halls, this heavy-duty double-sided tape provides extreme bonding strength while being residue-free and weather resistant.

✅ Key Benefits:

Extreme Strength: Holds up against vibration, foot traffic, and outdoor exposure.
Indoor/Outdoor Use: Originally made for both carpet and vinyl tiles indoors and outdoors.
Safe on Composite Decking: Won’t damage Trex®, TimberTech®, or Fiberon®.
No Drilling or Screws: Zero surface damage—great for rentals or clean installs.
Fast Application: No glue, curing time, or tools needed.

Surfaces It Works On

This double-sided tape works exceptionally well on:

✅ Concrete
✅ Composite Decking (Trex®, TimberTech®, Fiberon®)
✅ Wood and Treated Lumber
✅ Stone or Brick Steps
✅ Vinyl Decking
✅ Smooth metal or plastic stair trim

Note: Surface should be clean and dry for best adhesion.

How to Install Outdoor Stair Solar Lights Using Carpet Tile Tape

Step 1: Clean the Surface

Wipe the stair surface with a damp rag and let it dry completely. For extra grip, wipe with isopropyl alcohol.

Step 2: Cut the Tape

Cut a strip of double-sided carpet tile tape the same size as the mounting base of your solar light. For larger lights, use multiple strips or an "X" pattern.

Step 3: Apply Tape to Light Base

Firmly press the tape onto the back of the solar light's mounting base. Peel off the protective top layer.

Step 4: Mount the Light

Align and press the light firmly to the stair tread or riser. Hold in place with pressure for 30 seconds.

Step 5: Done!

The lights are now installed with no drilling, no mess, and no damage to your decking or steps. The tape will hold through rain, snow, and UV exposure.

Why This Tape Works on Composite Decking Like Trex®, TimberTech®, and Fiberon®

Composite decking has a smooth, nonporous surface that many adhesives struggle to grip. However, this heavy-duty carpet tile tape is built with a reinforced mesh backing and high-tack adhesive, allowing it to bond well to:

Trex Transcend and Enhance
TimberTech AZEK or Edge
Fiberon Good Life, ArmorGuard, or Paramount

And when you’re ready to remove the lights or move them—just peel slowly. The tape leaves no residue or damage behind.

Real-World Use Cases

Rental Property Owners: Install safety lighting without drilling into stairs or risking damage.
Homeowners with Trex or TimberTech Decks: Maintain warranty compliance—no screw holes or punctures.
DIYers & Outdoor Decorators: Set up holiday lights, path lighting, or patio safety lights in minutes.

Final Thoughts

Double-sided carpet tile tape isn’t just for flooring anymore. Its extreme strength, weather resistance, and surface safety make it a go-to product for mounting outdoor stair solar lights—especially on tough surfaces like concrete and composite decking.

If you’re looking for a secure, mess-free, drill-free solution for your exterior lights, this tape delivers.
