4.4 lb Glass Fiber for Concrete Mortar (4.4 Lb / 3/4"(19mm))

⭐ Key Features

•Say Goodbye to Fine Cracks:​ The alkali-resistant glass fibers distribute randomly throughout your cement mix, acting as a 3D reinforcement net. This significantly increases mortar toughness and effectively suppresses the formation and propagation of micro-cracks, resulting in a more durable, monolithic structure.

•Built-in Waterproof Barrier:​ Thousands of high-density fiber filaments fill internal voids, dramatically increasing the mix's density. This creates a continuous waterproof shield that effectively blocks water penetration, making it the ideal solution for wet areas like basements, ponds, and exterior walls.

•Superior Impact & Shatter Resistance:​ Interlocking fibers form a dense, high-strength mesh that tightly binds the cement matrix. This greatly enhances the material's ability to absorb energy, reducing damage from impacts, vibrations, and freeze-thaw cycles for a longer-lasting finish.

•Easy to Use, Quick to Integrate:​ Achieve perfect results in minutes. Simply mix the fibers evenly with your dry sand and cement, then add water. Just extend your standard mixing time by 30-60 seconds to ensure uniform fiber distribution throughout the batch.

•Precise Dosing for Optimal Performance:​ For standard concrete reinforcement, Use 2.2 lb. (1 pkg) per cubic yard (54 cubic feet) of concrete. In high-stress areas prone to heavy impact or severe weather, you can easily increase the dosage slightly for added strength and durability without waste.

📋 Product Description

Unlock the Strength & Longevity Your Concrete Deserves： Tired of watching your concrete projects succumb to unsightly cracks, water damage, or crumbling edges? The solution is here. Our premium alkali-resistant glass fibers are engineered to be mixed directly into your cement, mortar, or concrete, transforming ordinary mixes into a superior, multi-dimensional reinforcement system. It’s the professional-grade additive for DIY enthusiasts and contractors alike, designed to tackle the root causes of concrete failure. How It Works: A Revolution in Reinforcement： Unlike surface treatments or steel mesh, our fibers integrate throughoutthe entire volume of your mix. Once added, the thousands of individual 3/4-inch (19mm) filaments disperse randomly, creating a 3D micro-reinforcement network. This net acts from within to: 1.Hold the matrix together, bridging micro-cracks as they try to form. 2.Fill microscopic voids that water and chemicals use to penetrate. 3.Distribute stress evenly, absorbing impacts and structural loads. 5 Key Benefits for a Flawless, Lasting Finish： Permanently Combat Cracking: Say goodbye to spiderweb cracks and shrinkage fractures. The fibers dramatically increase tensile toughness, suppressing the formation and spread of micro-cracks, ensuring a smoother, more durable monolithic surface. Built-in Waterproofing & Impermeability: Protect your investment from the inside out. The fibers densify the concrete mix, significantly reducing porosity to form a continuous barrier against water, moisture, and salts. Say hello to dry basements, leak-proof ponds, and resilient exterior walls. Superior Impact & Abrasion Resistance: Ideal for high-traffic areas. The interlocking fiber mesh tightly binds the cement matrix, greatly enhancing its ability to withstand impacts, heavy loads, and surface abrasion, leading to a longer-lasting finish. Effortless to Use: No special skills or steps required. Simply blend the fibers evenly with your dry sand and cement aggregates before adding water. Just mix for an extra 30-60 seconds to ensure perfect, uniform dispersion. Achieve professional results with ease. Resists Freeze-Thaw & Chemical Damage: Enhance durability in harsh climates. The improved density and crack-bridging action minimize damage from repeated freezing/thawing cycles and exposure to de-icing salts or mild chemicals. Specifications & Simple Usage Guide： Fiber Length: 3/4 inch (19mm) Material: Alkali-Resistant Glass Fiber (AR-Glass) Packaging: Heavy-duty, resealable bag containing 2.2 lb (1.0 kg). Standard Dosage: Use one full 2.2 lb bag per cubic yard (approximately 54 cubic feet) of concrete for optimal reinforcement. For High-Stress Areas: In driveways, warehouse floors, or areas with severe freeze-thaw, slightly increase the dosage (e.g., 1.5 bags per cubic yard) for added protection. Perfect for a Wide Range of Applications： Residential & Garden: Driveways, sidewalks, patios, garden paths, shed bases, pond lining, stucco, and exterior wall renders. Indoor & Structural: Basement floors and walls, garage floors, interior screeds, and thin-set mortar for tile. Repair & Renovation: Ideal for concrete overlay, crack repair mortars, and structural patching compounds.
