Before you start applying stickers to LEGO bricks, it's important to make sure the bricks are clean and dry. Remove any dust or dirt from the surfaces of the stones with a soft cloth or compressed air.

Make sure you place the stickers carefully and precisely. It may be helpful to use tweezers to pick up and position the sticker. Make sure you keep the sticker straight and try to avoid air bubbles by applying it slowly and evenly to the stone.

Use your fingers or a soft cloth to gently rub the sticker to ensure it adheres well to the LEGO brick. Be careful not to leave fingerprints or smudges on the sticker during application.

If you notice that the sticker is not sticking well or is starting to peel off, you can use a little bit of water to dampen the back of the sticker. This can help improve adhesion. However, be careful not to get the bricks too wet as this can damage the LEGO bricks.

Once the sticker is properly applied, you can gently smooth it out with a soft cloth to ensure it is secure and free of bubbles or wrinkles.

It is important to note that stickers on LEGO bricks are generally permanent and difficult to remove without damaging the sticker or the brick itself. Therefore, make sure you are careful when applying stickers and double check the position before finally placing them on the stone.

By applying stickers to LEGO bricks you can add a personal touch to your builds and minifigures. With patience, precision and attention to detail you can achieve professional-looking results.

In short: To apply stickers to LEGO bricks, make sure the bricks are clean and dry. Use tweezers to place the stickers precisely and make sure they are straight and free of air bubbles. Gently rub the sticker to adhere it well. If the sticker does not adhere well, you can use a little water to dampen the back. Carefully smooth the sticker with a soft cloth. Be careful as stickers are usually permanent. With patience and precision, you can achieve professional-looking results when applying stickers to LEGO bricks.
