Review on Extinguisher Laminated Self Adhesive Weatherproof Protected by Mark Hamblin

For an internal one signs they are made solid. Good size, easy to see from a distance. I applied them to pieces of masonite that are attached to the ceiling with a small corner bracket. Seems to be holding up well, no signs of chipping. Gently peel off the release paper, align it where you want it, place one edge down, and gently roll the sign onto the surface. Smooth it out to minimize the ingress of air bubbles. Gently rubbing it with a soft cloth from the center to the edges to set it in place will also help push out any bubbles underneath. Would buy them again.
