BullGrip decals from Allied Graphics are designed for the portable sanitation industry. They are engineered to adhere to the challenging textures found on all major portable restrooms. When combined with durable, UV-cured ink, the adhesive has double the thickness of the company’s standard material, which allows the adhesive to seep into the textured surface when applied. Just clean the surface with isopropyl alcohol to remove any release agents or dirt. The decal can be applied with a squeegee, and the adhesive will have maximum hold after 48 hours. 800/490-9931; www.allied-graphics.com.
