12mm PP Fiber: Solution for Crack-Free & Waterproof Plaster

---

CETEX 12mm PP Fibers are high-performance, 100% virgin monofilament micro-fibers designed to protect your surfaces. While structural fibers are meant for heavy loads, our 12mm length is specifically optimized for secondary reinforcement. It acts as a specialized additive to stop cracks in their tracks and significantly enhance the waterproofing integrity of your walls and floors.

• External & Internal Plaster: Provides a deep-anchored mesh inside 15mm–25mm plaster coats.
• Crack Control: Best for preventing plastic shrinkage cracks in large surface areas like driveways and walkways.
• Waterproofing Base Coats: Perfect for terrace waterproofing, bathroom sunken slabs, and water tank linings.
• Roof Screeds & IPS Flooring: Prevents hairline cracks caused by extreme sun exposure and temperature changes.
• Anti-Shrinkage Mortar: Ideal for masonry joints and repair work where water-tightness is critical.
• Repair Work: Enhances the bond and prevents shrinkage in patching and rehabilitation mortars.

• Total Crack Control: The 12mm length bridges wider surface areas than shorter fibers, stopping plastic shrinkage cracks before they become visible.
• Enhanced Waterproofing: By eliminating the micro-channels (capillaries) that allow water to seep through, these fibers make your plaster naturally more water-resistant.
• No Rust, No Stains: Unlike chicken mesh or steel wire, 12mm PP fibers never corrode. Your exterior paint stays clean and free from rust spots forever.
• Easy Finishing: Specially treated to ensure they don't "ball up." They lay flat within the mix, leaving a smooth surface that is easy to finish with putty or paint.

• Plastering & Waterproofing: 125g per 50kg bag of cement.
• Floor Screeds: 0.6kg to 0.9kg per cu.m.
• Mixing: Add the fibers to the dry sand-cement mix or into the gauging water. Mix for 3–5 minutes for a perfect 3D distribution.

Technical Note: High-quality 12mm fibers must be made of Virgin Polypropylene. Many low-grade fibers are mixed with fillers to lower costs, which compromises the tensile strength. CETEX 12mm fibers have a specific gravity of 0.91 and will always float. If your 12mm fiber sinks, it will not provide the intended structural protection.
