LED stripl ights are part of modern home decor, but often encounter problems with strips falling off. Here are some ways to get LED strips glued again:

There are a few methods you can try to restick LED strip lights or make them stick again:

1.Clean the surface.

Clean the area where you want to restick the LEDs to remove any dirt or debris. Wipe down with rubbing alcohol or a degreaser to ensure the surface is free of oils. Allow to dry completely. This will help the adhesive stick properly.

2. Use double-sided tape.

Apply strips of strong double-sided tape to the back of the LED strip, covering the existing adhesive. Then firmly press the entire LED strip onto the surface you want to stick it to. Hold in place as directed, usually 30-60 seconds. The double-sided tape will adhere better than the original adhesive.

3. Apply superglue or construction adhesive.

For areas prone to high moisture or heat where tape may not hold up, use a strong adhesive like superglue, Gorilla Glue or construction adhesive. Apply a thin, even coat to the back of the LED strip and hold in place until the adhesive dries and bonds, usually 30-60 minutes. Be very careful not to get adhesive on the front surface of the LEDs.

4. Add mounting hardware.

As an alternative to adhesive, you can secure the LED strip using small nails, screws, mounting bases or brackets. This provides a more permanent solution if the area is not suitable for glue or tape. The mounting hardware holds the strip in place mechanically without adhesive.

5. Increase surface contact.

For larger LED fixtures like rope lights, string more wire or twine between attachment points to increase surface contact. The more surface contact, the more adhered and secure the entire fixture will be. Twist wire into a net-like pattern across the back for maximum grip.

6. Replace adhesives strips.

If the existing adhesive strips on the LED strip are no longer sticky at all, you may need to remove them and apply new double-sided adhesive strips or tape to the back of the strip. Press onto the surface as directed to restick.

Soldering or brazing method can achieve the strongest LED strip connection, but is also the most technically difficult method. If you do not have the relevant experience, inadvertently easy to cause damage to the LED strip.

Here are some considerations for soldering LED strips.

1. Choose the right soldering wire

The best choice and LED strip Snippet pads and solder joints to match the material of the solder wire, the common tin solder wire, silver glue solder wire, etc.. The diameter of the wire should also match, too thin will lead to weak solder joints, too thick is not easy to operate.

2. Pre-welding treatment

Clean the LED strip solder joints and pads, remove rust and dirt. If necessary, you can slightly polish the surface of the solder joints. Clean treatment can get the best soldering effect.

3. Select the right solder

The flux in the solder composition is different, the melting point and fluidity is also different. Generally, the melting point of tin studs is high and the fluidity is poor. The melting point of tin wire and tin bar is lower and the fluidity is better, which is more suitable for the welding of LED strip.

4. attention to prevent overheating

The components and lines in the LED strip are very weak and easily damaged by high heat. Welding should be as fast as possible, control the temperature to avoid overheating of the welding parts. The operable time is generally 3-5 seconds.

5. Post-soldering inspection

Check whether the solder joint is smooth and flat, whether the solder is covered comprehensively, and whether there is a short circuit or leakage point. Lightly pull slightly to test the strength of the welded joint. If necessary, use an electric tester to check whether the electrical connection is good.

6. Increase protection

If the LED strip is used in outdoor or humid environment, it is recommended to apply a layer of waterproof adhesive or heat-shrinkable tube for protection after welding to prevent rusting and leakage.
Soldering method can get the strongest LED strip connection, but also easy to cause irreparable damage. Unless other bonding methods have been tried and cannot be achieved, it is not recommended to choose the direct welding method. If you must weld, be very careful and follow the above precautions to reduce the risk of damage.
