Sto Powerwall® Stucco is better than field mixed stucco because:
Feature	How/Why	Benefit
Higher compressive strength	More controlled mix Fibers added	Higher impact resistance
Higher tensile strength	More controlled mix Fibers added	Less cracking resulting from structural movement
Lower weight per square foot	Only need to build up to 3/8"-1/2" Material does not absorb as much moisture	Lower and less expensive structural requirements
Superior weather resistance	Sto elastomeric coatings/finishes bridge hairline cracks	Does not allow moisture to get into the wall Helps maintain appearance
Faster installation	Less field mixing = less time and better consistency Can be applied in one application	Lower installation costs
All the above help improve your reputation and allow you to make your customer satisfied.
