Imasco stucco has been designed to last. The system is reinforced with a quality acrylic top coat and base coat to resist cracking, fading, and water penetration. With properly trained installers, it can last 30 years or more with little or no upkeep. The acrylic resin base gives the flexibility to the structure required to live with Calgary freeze-thaw cycles and maintains a waterproof surface, which traps moisture. The outer shell is strong enough to resist direct sunlight, falling snow, rain, and some strong winds.
