Wall Sticker Application Instruction Our wall decal application instructions will make it easy for you to apply your wall decals. 1). The surface you wish to attach your decal must be clean and free from dust, grease or any other contamination. 2). Simply peel those pre-cut pieces of wall stickers off from backing paper and apply them on the desired area. Freshly painted or lacquered surfaces must be allowed to completely cure before the decal is applied. We recommend waiting for minimum of 2-3 weeks. 3). Press firmly to squeeze out any air bubbles. Please Note: It will be helpful and fun if you take help of your friends or family members to stick the wall decals on your wall.
