Loca glue separating after cure
Hello there guys, need a little bit of help. A while ago I cracked my galaxy s4 glass and decided to fix it myself. I successfully separated the glass from the LCD cleaned the LCD, applied loca glue. This is where the first problem occurred, I could not get the glass to lay flat and without lifting when trying to cure glue so i cured the glue applying pressure to the screen and after 45 mins of curing it looked perfect. After 14 days the glue began to, i guess re-liquify/lift. I was thoroughly confused to proceeded to but another kit with different loca glue. This time I managed to get the glass the lay flat and perfect with no bubbles and no need to apply pressure. So i played the phone to set in the sun for 90 mins and then put under a uv lamp for 15 mins. Once again screen looked perfect but this time after just 2 days the glue one again began to re-liquify/lift ? again. I need to find a way to get my glass to cure properly without the need of an autoclave or any really expensive tools.
