The attached picture of 1’’ painted stucco foam & acrylic address numbers The 24’’ tall numbers were cut out of 1’’ foam & 3/16’’ black acrylic which was used for the face of the numbers.  The foam was painted with a stucco coating to prevent the elements from the environment, birds & bugs from eroding the foam. This type of process is used for most outdoor signs because it keeps the weight down and the 3 dimensional impact the same, also while keeping costs down for our customers. The numbers were installed by etching a paper pattern on the building & than mounting the numbers with double sided foam tape & silicon to the building.  The numbers were installed at the top of the building using a 45 foot boom lift.
