(12) Frequently Asked Questions (FAQ)

1. Does Anti-Cracking Mesh Completely Prevent Cracks?

While anti-crack mesh—especially fiberglass mesh—significantly reduces the likelihood of cracks forming in plaster, it does not guarantee 100% crack prevention. The mesh helps to distribute stress and movement more evenly across the plaster surface, making it less susceptible to common causes of cracking, such as foundation shifts or drying shrinkage. However, extreme structural movements or other factors, such as significant moisture damage, can still cause cracks to appear. Regular maintenance and inspections are essential to catch and address potential issues early.

2. Can I Use Anti-Cracking Mesh on Old Plaster?

Yes, anti-cracking mesh can be applied to old plaster as part of a repair or renovation project. If your existing plaster is cracked or damaged, you can use fiberglass mesh or steel mesh to reinforce the plaster before reapplying a new layer. Masonry wire mesh is also a good option for areas that require extra strength. When applying mesh to old plaster, it’s important to clean and prepare the surface properly by removing any loose or crumbling plaster, ensuring good adhesion for the mesh and plaster. This will help prevent future cracking and improve the durability of the wall.

3. What’s the Difference Between Fiberglass Mesh and Masonry Wire Mesh?

Fiberglass mesh and masonry wire mesh are both types of anti-crack mesh, but they differ in material, strength, and application:

  • Fiberglass Mesh: Made from woven strands of fiberglass, this mesh is lightweight, flexible, and resistant to corrosion. It is especially effective in applications where moisture resistance is important, such as waterproofing or reinforcing plaster in damp environments. Fiberglass mesh is ideal for smoother surfaces like drywall or newer plaster applications. Its flexibility and ease of installation make it a popular choice for general reinforcement and preventing fresh plaster cracking.

  • Masonry Wire Mesh: This mesh is made from steel or other strong metals and is often used for heavy-duty applications. It is typically used in more demanding environments where additional strength is needed, such as on concrete walls or masonry surfaces. Masonry wire mesh is ideal for concrete block mesh applications, providing extra support to prevent cracks in new plaster and ensuring the long-term stability of the surface. It’s more rigid and less flexible than fiberglass mesh, making it better suited for applications where substantial reinforcement is necessary.

Both types of mesh offer excellent support, but your choice depends on the surface type, environmental conditions, and the level of reinforcement needed for your project.
