Adhesive door frame edges need to be selected according to the material, generally you can use instant glue, slow-dry glue, nail-free glue, UV shadowless glue, swelling glue, etc.
UV shadowless glue belongs to two kinds of bonding. It is only effective if it is a transparent part. The bonding strength is also relatively good, and it dries quickly. After this glue is irradiated by ultraviolet rays, the reaction will be strong and the efficiency is very high. .

When repairing viscose, to avoid applying glue on a large area, you only need to divide the door frame into four equal parts, and point five points. The two ends and the middle must be glued, and then installed Go back and hold it for a few minutes, and after letting go, the door frame edge will not fall off.
Different glues have different effects, and you should choose and use them according to the material and specific conditions of the door frame edge.
The most convenient way is to use instant glue. After the glue is applied, it can stick together immediately, and the effect is relatively good. The effect is very good for metal and plastic parts. But this kind of glue is easier to paint, and it is easy to have white edges around it after a long time.
The filling effect of slow-drying glue is good, and it will not cause white fog, and at the same time, it will not appear embrittlement. The longer it is used, the better the adhesion will be, but the drying will be slower.
In the case of sticking wooden doors, you can use nail-free glue. Before using, clean the surface to ensure that the surface is free of oil and dust, and then use a sealing gun to squeeze out the glue.
