2mm adhesive for mobile phone repair

Wondering whether you need adhesive and what kind for your repair? All phones and tablets are held together by adhesive and it can be a pain. With our guide, you will be informed so your repair can go smoother!

Do I need adhesive for a phone or tablet repair?
When opening the device, you will break the existing adhesive seal around the edge. The easiest way to work with adhesive is with a little heat. You can use a blow dryer or a heat gun. Apply a little heat, but NOT too much as you can melt. This will soften the adhesive and allow you to work with it - cutting it and opening device. When you go to close up your device, you may need additional adhesive to close it up with a more secure seal. This applies to any repair where you have to open the device from screen replacement and changing a battery, to swapping out a home button or camera.

What are my options for adhesive?
It ranges from pre-installed on the new screen edge to tape that is designed for mobile and tablet repairs. The best case is if the part comes pre-installed with adhesive. This is available for iPad glass screens and is the easiest for a repair. You just have to remove the film on the tape and stick to device. At RepairPartsPlus, we have worked with our suppliers to always have the tape pre-installed if available as well as having a stronger, best-in-class tape in the market.

If not pre-installed on new part, you have 2 options - pre-cut adhesive specific to your device or general 2mm adhesive strips that fit most devices and you can cut to size needed and apply.

It's a good idea to have extra adhesive as well. It's a small cost and can save you some headache in case you have trouble applying and want to restart. Also a little B7000 or general all-purpose glue can be helpful if tape not holding in a spot due to bent frame or pressure.

How to remove adhesive after a repair?
After a phone or device repair, you may have sticky adhesive and residue that needs to be cleaned away. You can do this with rubbing alcohol or a little bid of WD-40. Just put a small amount of the solvent on a cloth or cotton swab and then gently rub the adhesive.

Adhesive needs by Repair Type

Iphone Screens
If you are replacing the full LCD display screen as this includes the frame as well, new adhesive is not required. However, a pre-cut frame adhesive is valuable to create a tighter "closer to waterproof" seal. If you are replacing the top front glass panel only, then adhesive is needed.

Adhesive for iPad Pro repair

iPad Screen

Adhesive tape is key for repairs on iPads and tablets like Microsoft Surface or Galaxy Tab. There is more edge area on these devices and additional adhesive will insure your device is closed up properly and stays that way. It is helpful anytime you open the device. It is necessary, if replacing the front glass or glass touch digitizer on an iPad or tablet to secure the glass. The strength of the tape is also important. At RepairPartsPlus, we include pre-installed Tesa tape with our iPad kits as it is very strong and has a good results for mobile repairs. If you want to have extra tape, check out the red Tesa tape. Red TESA tape is very strong and we recommend for iPads. TIP: Glue Dots can help if need a little more hold. Cut to fit and place them in the corners and in the middle of the frame.

Here are some installation tips:
The adhesive is pressure -activated. While it is drying/curing after sealed, apply a very SLIGHT pressure on top of the device screen for 4-6 hours to make sure the adhesive remains in contact with the frame of the iPad. You can place the iPad face down on a towel, and put 3" thick books like texbook or phonebook, on top of the device as a weight. IMPORTANT: Too much pressure will crack the new glass. DO NOT press on corners or around home button.

Properly clean the previous adhesive from the housing. You can use IPA or Acetone to soften up the adhesive, and then scrape away most of it with a flat tool like a putty knife (be careful of the inner flex cables and components). Use an alcohol wipe to clean the rest off.

Make sure the flex cables are properly sitting within the device. They must lay flat before the iPad is closed, as even the tiniest amount of pressure will cause the adhesive to let go of the glass or new screen. Also if the housing or frame is even slightly bent, this will cause the adhesive to lift. In this case, the housing needs to be fixed. This can happen right away or over time. If tape won't hold in a spot, you may want to use a little B7000 or other all-purpose glue. You can get that here or at local stores.

Full Display Assembly
It depends. The full screen includes the LCD display and the glass touch digitizer which is fused together. The existing adhesive on the phone will be sufficient, but it may be handy if you have to scrape all the original adhesive off when opening the device. You may also want it to create a more tight "closer to waterproof" seal.

Battery Adhesive

For iPhones and iPad you need adhesive to hold the battery. For other phones like Galaxy, it is not necessary. For iPhones and iPad there is a specially designed battery adhesive strips to hold the battery in place and allow future removal easier. The screen frame adhesive is also helpful to reseal your device after opening.

These battery adhesive strips are essential, but can be a little tricky. It's the hardest part of the whole replacement. Get an extra one as a back up. Here are a few videos that will help on how to work with the strips.

2mm Adhesive Tape Strips

Double-sided adhesive tape that is 2mm width is easiest to use and specially designed to fit the mobile device / phone edges. It is very thin and fits around the edge of the screen. 3M offers it and Tesa brand and red tape lead in holding strength and are preferred for larger tablets like the iPad. If you are using the 2mm adhesive, just pull off a each strip with tweezers and cut if need and apply until all edges covered. Also apply strips to the middle of solid parts of screen at top and bottom. This tape will hold the new glass screen in place.

Tip: Make sure to clean the screen area where the adhesive will go BEFORE applying.

Pre-Cut Frame Adhesive for iPhone and more

Pre-cut frame adhesive is another option for some of the most popular phones. it is cut to the shape of the phone. It also adhers the screen to the frame when you close it up. Makes it more tight and waterproof. Here is a link to a YouTube video for how to use the full size frame adhesive on iPhone 6s or higher:

UV Glue

Note: UV glue can be used for sealing, but can result in damage to device if too much is used and it seeps into other parts of the phone. Although it is a stronger, longer lasting bond, the adhesive strips are a much safer solution. Use of UV glue requires a curing lamp. We don't recommend glue for first time DIYers. UV glue and a curing lamp can be purchased separately if desired.
