If the inkjet advertisement on the door of the store needs to be replaced with a new inkjet cloth, but you don't want to remove the angle iron shelf, you can consider the following steps to quickly replace it:

Prepare tools and materials: you need to prepare a new inkjet cloth, all-purpose adhesive, brush, hand drill, steel sleeve and dovetail nail.

surface cleaning: clean the surface of the old spray-painted cloth with detergent or clean water to ensure that there is no dust, dirt or other impurities on the surface.

paste the new spray-painted cloth: lay the new spray-painted cloth flat on the old spray-painted cloth to ensure alignment and smoothness. Then use all-purpose glue to paste the periphery of the new spray-painted cloth on the angle iron frame. Pay attention to evenly apply all-purpose glue to avoid bubbles or wrinkles.

fixing the spray-painted cloth: use a hand drill and a steel sleeve to fix the dovetail nails on the angle iron frame along the periphery of the new spray-painted cloth, so as to ensure the proper position and spacing of the nails and avoid damaging the spray-painted cloth.

Trim the excess part: After the new spray-painted cloth is completely fixed, trim the excess part with scissors or blades to ensure that the new spray-painted cloth is completely attached to the angle iron frame.

it should be noted that when replacing the spray-painted cloth, it is necessary to ensure safety and avoid accidents during operation.
