When is it appropriate to use fiberglass mesh?

Many people may hang a mesh fabric on their walls when decorating. Generally, a mesh fabric should be hung before applying putty to prevent cracking later. So, what are the steps for wall decoration, puttying, and hanging the mesh fabric? How exactly is it done? Let's take a look!
**First, should you apply putty first or hang the mesh fabric first? Hang the mesh fabric first, then apply putty. The specific steps are as follows:**
1. First, level the wall surface. This ensures a more secure adhesion between the mesh fabric and the putty. The wall surface should be clean, and any uneven areas should be smoothed. If there are cracks, they need to be treated. For example, cracks should be glued with white latex, and then a primer should be applied. Apply the primer to every corner, ensuring even coverage and no missed spots.
2. After the preliminary work is completed, you can apply the mesh fabric. For lightweight or insulated walls, paper mesh is necessary. Choose a slightly better quality mesh fabric and white latex for better crack prevention. After it is firmly attached and completely dry, then apply the putty. This step also requires careful attention. Hubei Zhuoran New Materials suggests choosing a putty powder with fine particles and a consistent texture. Apply the putty 2-3 times, allowing each coat to dry completely before applying the next. This ensures a better finish.
3. If the wall needs to be painted with latex paint or wallpapered, this can be done directly after these steps are completed, and the decorative effect will be even better.
II. The Functions of Hanging Mesh Fabric on Walls
1. For interior wall construction, it provides both corrosion protection and crack resistance. Many people have found that if mesh fabric is applied to the wall, cracks will not appear after several years.
2. For exterior walls, one of the biggest benefits of hanging mesh fabric is its insulation effect. This is especially beneficial after installing underfloor heating, resulting in better room insulation.
