The GATEX G125 Standard fiberglass mesh must be embedded into a base layer of smoothing adhesive (minimum 2–3 mm) applied to the insulation surface. Installation should proceed as follows:

Unroll the mesh vertically from top to bottom
Embed evenly using a float or spatula
Overlap mesh strips by at least 10 cm
Avoid folds, wrinkles, and air pockets
Apply a second adhesive layer over the mesh for full coverage

‍

Strong, stable fiber weave with consistent mesh openings
High mechanical strength and dimensional stability
Soft and flexible for easy on-site handling
Alkali-resistant coating for long-term durability
Slip-resistant surface texture
Tear-resistant and anti-snag construction
Reduces thermal deformation in insulation systems
Prevents façade cracking and surface damage
