How to Choose the Right Fiberglass Mesh for Your Stucco or EIFS Project
Not all fiberglass mesh is created equal. Choosing the correct type can mean the difference between a long-lasting finish and costly repairs. There are three main types to consider: standard weight, heavyweight, and corner mesh.
Understanding Mesh Types
- Standard Weight Mesh – Ideal for general-purpose wall reinforcement and crack resistance. This is the most commonly used mesh for EIFS and stucco systems and provides a good balance of flexibility and strength for most installations.
- Heavyweight Mesh – Used in high-impact areas or where additional strength is required. This mesh is often recommended for the lower portions of walls, around doorways, or in commercial projects where impact resistance is a priority.
- Corner Mesh – Pre-shaped to wrap external corners, this mesh reinforces areas most prone to damage. It ensures crisp corners and protects against knocks and weathering.
When to Use Each Type
Selecting the right mesh depends on the specific needs of your project. Use standard weight mesh for typical residential applications or areas that won’t be subject to high traffic or impact. For commercial properties, schools, hospitals, or any structure exposed to wear and tear, heavyweight mesh is a safer option. Corner mesh should always be used on external angles and edge terminations to maintain clean lines and protect the structure.
Installation Best Practices
Proper mesh installation is just as important as choosing the right type. Follow these tips for optimal performance:
- Always embed the mesh into a fresh, wet base coat using a stainless steel trowel.
- Smooth out wrinkles or bubbles immediately to avoid weak spots.
- Overlap adjacent mesh strips by at least 2 inches to ensure continuous coverage.
- Let the base coat cure completely before applying the finish coat.
Why Quality Matters
Cheap or low-quality mesh may save money upfront, but it can lead to delamination, surface cracking, or system failure over time.
