Choose a Smooth and flat wall surface (not textured)
Clean The media to install. Make sure no dirt dust, water, or oil sticks to the wall.
Remove The wall sticker from the paper slowly so as not to stick to each other.
Then Stick (paste) the wall sticker to the wall. Don't press it until the correct position is correct as you wish.
Important Instructions:
For walls, New in paint waits for at least 3 weeks for the wall to correctly dry, because the paint that is still wet can reduce the adhesion of the wall sticker.
Wall stickers can indeed be removed in place but can be removed more often than the adhesion becomes getting weaker.
The base color of the surface/wall can affect the brightness and dim of such sticker color.
