Adhesive is not required, if you are replace the full LCD display screen as this includes the frame as well.

2mm Adhesive Strips
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.

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.
