Fiberglass Mesh

Reinforcement

Fiberglass Mesh is a reinforcement layer embedded into plaster, render and waterproofing systems to distribute stress across joints and repairs. This flexible, durable mesh prevents cracks by bonding evenly with plaster, drywall compounds, and more, which suits renovations or new builds. Pair it with Lunaris AquaPro for a waterproof, crack-resistant finish that lasts, suitable for practical users and contractors alike.
