It fills the gap between ordinary stucco and elastomerics.
Ordinary stucco has a number of drawbacks.
Very heavy, creating handling problems, shear strain on walls and flat surfaces, and injuries. Limitations to use, especially in high humidity or heavy rain environments. To solve these problems, elastomerics were created. Elastomerics generally require only one coat of material in a very thin layer, applied directly over most substrates. Since they are extremely elastic, cracking is unusual.
