What are my options for adhesive?
It ranges from pre-installed on the new screen edge to tape that is designed for mobile 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 tape than is standard 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
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 LCD Screen
Adhesive is not required, if you are replace the full LCD display screen as this includes the frame as well. However, in iPhone 7 and newer, 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 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 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 for insurance, check out the red tape. Red tape is very strong and we recommend for iPads along with TESA tape.
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.
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 putthy 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.
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.
Front Glass Only
Adhesive tape is necessary if replacing the front glass or glass touch digitizer to secure the glass to the rest of the screen.
For iPhones you need some kind of adhesive. For other phones like Galaxy, it is not necessary. For iPhones there is a specially designed battery adhesive strips to hold the battery in place and allow future removal easier. The iPhone frame adhesive is also helpful to reseal your device after opening.
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:
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.
