Cheapest option: 90 lb Bags at $154.00For most stucco jobs, 3 coats (scratch, brown, and finish) at 3/8" each is standard. The 90 lb bags cover more area per bag and often cost less per square foot — but they are heavier to mix and handle. Choose based on your project size and crew capacity.

This is a material estimate only. Actual coverage varies with surface texture, application method, and mix consistency. Always order extra to avoid mid-job shortages — stucco from different batches may not match perfectly.
