Cement board stucco is a stucco cladding system where the base coat and finish are applied over cement backer board instead of traditional lath and scratch/brown coats. It combines the solid, impact‑resistant feel of stucco with the stability and moisture resistance of cement board, helping reduce cracking, improve durability, and speed up installation compared to a full three‑coat system. This type of system is popular on both commercial and residential projects because it offers good weather resistance, fire resistance, and energy efficiency while providing a clean, flat substrate for acrylic or cementitious finishes.
