Traditional stucco requires three coats: scratch coat, brown coat, and finish coat. Apply over metal lath or masonry surface. Allow proper curing time between coats (24-48 hours).

Material & Cost Breakdown

Material Calculation Formula

Total Square Feet = (Wall Area × Number of Walls) – Openings × Waste Factor

Calculate wall area by multiplying length × height. Multiply by number of walls, subtract openings (windows/doors), then apply waste factor (typically 10-20%) for application losses.
