Here are some precautions for installing wall advertising poster frames:

Preparation

- Safety assessment: Conduct a safety assessment of the construction environment, including the structural safety of the building and the safety measures for the workers. For example, when installing at a high altitude, make sure that the installers have a high-altitude work permit and sign a safety responsibility statement.

- Material selection: Select appropriate installation materials and tools according to the materials and weights of the poster frames and the wall. For example, heavier poster frames need to be fixed with screws, while lighter ones can be fixed with glue or tape.

- Wall treatment: Before installation, make sure that the wall is clean, flat and dry, without dust, oil stains, etc. You can wipe it with a cleaning cloth and sand it with sandpaper if necessary to improve the adhesion.

Installation process

- Measurement and positioning: Use a level and measuring tools to determine the accurate position of the poster frame on the wall, ensure that it is level and meets the display requirements, and mark it with a pencil to avoid installing it askew.

- Installation method: If you use glue to paste, pay attention to applying it evenly to avoid overflowing and polluting the wall, and wait for it to dry and solidify according to the instructions of the glue. If you use nails or screws to fix, make sure that they are firmly inserted or drilled into the wall, and the screws are tightened and the nails are nailed firmly to prevent the poster frame from loosening and falling off.

- Poster installation: For poster frames with borders, insert the edges of the poster accurately into the card slots to ensure that it is flat without wrinkles. If it is fixed by magnetic attraction or other means, check the firmness of the magnetic attraction to prevent the poster from falling off.

Post-installation inspection

- Stability check: After the installation is completed, gently pull the poster frame to check whether it is firmly and stably fixed. If there is any looseness or unevenness, adjust and refix it in time.

- Cleaning and tidying: Clean up the garbage and surplus materials generated during the installation process, cut off the surplus tape or glue, and keep the wall and the installation area clean.
