Signs for San Diego replaces address numbers on commercial buildings all the time. Why we need to do this? Birds!! Birds are destroying Exterior Building Signs like your Address Numbers. It is a problem with materials. We can help you make a better choice..
In the 1980s foam letters and numbers started to become popular. A lot of this has to do with material costs and a way of shaping these with a “hot wire”. 4 types of plastic expanded foam materials are common for Exterior Building Signs or Address numbers. Two types of foam have a couple fatal flaws:
Birds don’t normally eat foam, there is no nutritional value to them. They are pecking and clawing your numbers for fun. Birds perch on the top parts and in the centers of the “0”s, “4”s, “6”s, “8”s and “9”s in. In most all cases, the upward facing edges are where the deterioration starts. The letter is pulled apart from claws, and becks. The sun attacks the foam. The paint on the letter thins, cracks and birds peck at weak areas and exposing the foam. When the protective layer is penetrated, birds enjoy picking the edge of the paint layer completely off. Holes can be repaired with a polyurethane caulking. If you can see the damage, but birds peck at the top of the letter where is impossible to see. Birds do not like stucco and a thick coating of stucco keeps the birds away.
On the south side an Exterior Building Sign like an address number is in the sun all day long. The numbers on the south side have maximum exposure to Ultra Violet light. Normally the damage will be worse on the south side, but the east, west and north facing sides still have bird damage and take longer. The UV breaks down the foam and in extreme cases a laminated face of a number falls off. Paint with a UV inhibitor, Dark colors such as black, dark brown, dark reds, and blues resist UV deterioration much more effectively than lighter colors such as yellows, whites, light blues, and grays.
In the 1980s and peaking in the early 2000s foam were commonly available. Foam is cheaper, easier to shape and all the rage, but not all foams are created equal: Learn More About Materials Here
