Stucco is a building material composed of Portland cement, sand, lime, water and aggregate, used for both interior and exterior wall finishes. It creates high-end exterior finishes and remains a Calgary favourite, even though concrete and other systems have replaced it in some other markets.
Traditional stucco was the original version of stucco
Traditional stucco, originating from ancient Roman times, is a mixture of cement, lime, and sand. It’s the long-standing benchmark for durability and water resistance, a hands-on, multi-coat system that, done right, lasts decades.
Acrylic stucco is a newer type of stucco
Acrylic stucco, the more recent of the two, is a sand-and-cement base with acrylic and polymers added. The polymers make the finished surface more flexible, more crack-resistant, and easier to colour-match across large elevations.
Both types of stucco have their own advantages and disadvantages
Neither is universally better. The right call depends on substrate, exposure, your design preference, and budget. Below is the head-to-head.
Cost and durability are among the main differences between traditional and acrylic stuccos
Acrylic stucco is more expensive upfront, but it generally offers superior longevity, potentially lasting up to 10 years longer than traditional stucco in the right conditions. Traditional stucco, however, is more durable in raw strength terms thanks to its cement-based composition. It’s also more prone to cracking and requires more ongoing maintenance.
Differences in application, performance, and aesthetics
Traditional stucco requires three application layers: lath (wire mesh), a scratch coat, and a brown coat, followed by the finish coat. The system depends on a layer of wire mesh and two or three coats to perform properly.
Acrylic stucco is more flexible and can be applied directly over wood-sheathed walls (with the right substrate prep) without the same moisture-driven concerns. Aesthetically, traditional stucco delivers a rougher texture and an aged, premium look; acrylic offers smoother finishes and superior colour retention. Traditional stucco typically needs painting after curing, while acrylic systems come pre-coloured in almost unlimited variety.
Wrapping up
The short version: traditional stucco gives you texture and time-tested durability; acrylic gives you flexibility, colour, and modern smoothness. As we tell every client, it’s always best to choose the right product for your specific project, not whichever brand you saw on a billboard.
