Some of the styrofoam pieces can be coated to give them extra strength. Styrofoam can also be coated for easy painting. The final finish can come in a large variety of options: sand, keystone, light sand, white sand, 2-tones, knock down.
There are quite a lot of other advantages of using styrofoam instead of precast. Its low thermal conductivity, its high strength for its weight ratio, and its effectiveness for use in a wide range of temperatures. It also is not affected by vibrations, it is available in a very wide range of sizes, it is easy to handle and it is clean, and odorless, and it does not irritate your skin. It is very durable; and the best thing of all is that using Styrofoam rather than Precast is the money it saves the contractors.
