Mapei Mapenet 150 (Fibreglass Mesh) - Alkali-Resistant Fibreglass Reinforcement Mesh

Alkali-Resistant Fibreglass Reinforcement Mesh for Use with Waterproofing and Levelling Systems

Mapei Mapenet 150 is a pre-primed, alkali-resistant fibreglass mesh designed to reinforce cementitious waterproofing membranes and smoothing compounds. Used with products such as Mapelastic Smart, Mapelastic Foundation, and levelling mortars, it improves crack resistance, enhances durability, and stabilises substrates subject to movement or thermal expansion. Ideal for reinforcing waterproof coatings on façades, balconies, terraces, and render systems.

Key Features & Benefits

• Alkali-Resistant: Treated to resist degradation in high-pH cementitious environments.
• Reinforcement for Membranes: Prevents micro-cracking and enhances tensile strength of flexible coatings.
• Lightweight & Easy to Handle: Cuts easily and embeds into wet mortar or membrane layers.
• Wide Application Range: Suitable for waterproofing systems, façade coatings, levelling compounds, and render reinforcement.
• Conforms to Substrate Irregularities: Ideal for use on both flat and slightly contoured surfaces.
