Frequently Asked Questions
What is the difference between 2-coat and 3-coat stucco?
Three-coat stucco (scratch, brown, finish) is traditional and more durable. Two-coat systems are faster and work well over solid substrates like concrete or CMU blocks.
How thick should stucco be?
Three-coat stucco is typically 7/8" thick total. Two-coat systems are about 5/8" thick. Each coat is applied in layers with drying time between.
Do I need metal lath?
Yes, metal lath (wire mesh) is required over wood sheathing to provide a base for the stucco to grip. It's not needed over concrete or masonry.
How long does stucco take to dry?
Each coat needs 24-48 hours to cure before applying the next coat. Total installation takes 5-7 days for a three-coat system.
