DIY Stucco Application: What Every Homeowner Should Know Before Starting
Tackling a stucco project on your own can be rewarding—but it also comes with challenges that can affect durability, appearance, and even your home’s structure. If you’re a hands-on homeowner or DIY enthusiast, here’s what you need to know before mixing your first batch of stucco.
✅ Understand the Basics: What Is Stucco?
Stucco is a cement-based exterior finish applied in multiple layers over lath and sheathing. It’s known for durability, fire resistance, and its clean, seamless finish—when applied correctly.

Use fiberglass-reinforced mixes to reduce cracking

Do small test patches to match texture before applying everywhere
