Attention must be paid to hanging grid cloth when plastering the interior walls

If there is no omission in the annotation, any connection between columns, shear walls, and all infill walls in concrete structures requires mesh cloth or steel wire mesh, regardless of the type of infill material. Steel wire weaving or mesh is made of fiberglass weaving. Steel wire mesh is more sturdy and more expensive than mesh fabric.
To prevent wall cracking, a mesh cloth should be hung for plastering the interior wall. New houses are usually delivered shortly after construction, so the settlement of the walls is not very good. At this point, there will be slight cracks at the joints between lightweight walls, beams, and load-bearing walls as they settle. For lightweight walls, kraft paper or Dacron cloth can be used for treatment. The corner joints can be treated with strip perforated kraft paper. Grid strips are generally used for handling slightly larger gaps.

Houses that are slightly older are usually made of brick walls or sandstone walls, which are prone to cracking. Because the bricks have air flow, no one can avoid it. The use of stickers and other methods can prolong the time for cracking to occur, but cannot guarantee complete non cracking.
Nowadays, energy-saving exterior wall insulation plastering is needed to prevent cracking. Due to the low strength and thickness of insulation dry powder mortar, it is easy to crack, so it is necessary to add mesh cloth before covering the surface layer.
Mesh cloth is glass fiber woven with medium alkali or alkali free glass fiber yarn and coated with alkali resistant polymer lotion. Mesh fabric series products: alkali resistant GRC fiberglass mesh fabric, alkali resistant wall specific mesh and stone mesh fabric, marble back mounted mesh fabric.
Alkali resistant reinforced fiberglass mesh fabric is a new type of inorganic composite material that can be embedded in walls to evenly disperse the compressive and impact stresses on the wall, giving the insulation layer high impact resistance and acting as a "soft steel bar".
