Fiber Resa
Fiber Resa by Redwop Chemicals is an advanced fiber additive designed to enhance the performance of concrete and mortar. It prevents shrinkage cracks, reduces water permeability, and helps protect the steel reinforcement from corrosion, ultimately improving the durability and life of structures. Environmentally friendly, cost-effective, and non-hazardous, Fiber Resa also increases flexibility, tensile strength, and compressive strength, ensuring more yield from the mix. It’s non-corrosive, chemically inert, and alkali-proof, making it ideal for use in industrial floors and various concrete applications.
Redwop Fiber Resa is a premium-grade, alkali-resistant glass fiber mesh tailored to reinforce waterproofing and protective coating systems. Designed to seamlessly integrate with cementitious and polymer coatings, it forms a unified composite membrane that improves tensile strength and crack resistance—ideal for surfaces exposed to movement or stress.
Ideal Applications
Ideal for use in bathrooms, kitchens, balconies, windows, doors, expansion joints, and tile edges, Redwop Sealant bridges gaps up to 15 mm while accommodating structural movement. It is equally effective for interior drywall seams, exterior façade perforations, plumbing fixtures, and metal or glass-to-building-seal interfaces, providing reliable protection in residential and commercial settings.
Application Guide
Begin with clean, dry, and dust-free joints. For deep gaps, insert suitable backer rods. Cut the nozzle at a 45° angle to match joint size and apply a continuous bead. Smooth the sealant with a finger or tool within 10 minutes of application. Allow 24 hours for initial cure and approximately 7 days for full performance. Sealant can be painted after 48 hours, and tools can be cleaned with water before drying.
Key Features & Benefits
Redwop Sealant offers superior elasticity (up to 25% joint movement) and excellent UV and moisture resistance, making it perfect for critical applications. Its low-VOC, non-yellowing formula is paintable within 24–48 hours and won’t shrink or crack over time. The sealant adheres securely to moist or dry substrates and resists mold and mildew, ensuring long-term performance in demanding environments.
FAQ's
Fiber Resa is an advanced additive for concrete and mortar, designed to enhance the properties of the mix. It helps in preventing shrinkage cracks, improving strength, and increasing the durability of structures.
Fiber Resa prevents shrinkage cracks, reduces water permeability, improves the tensile and compressive strength, and enhances the flexibility of concrete. It also protects steel reinforcement from corrosion, thus increasing the structure's lifespan.
Yes, Fiber Resa is environmentally friendly and non-hazardous, making it safe for use in various concrete applications without harming the environment.
Absolutely! Fiber Resa minimizes the need for steel reinforcement in industrial floors and improves the durability and flexibility of the concrete, making it ideal for such applications.
No, Fiber Resa disperses easily in dry ready mix and does not affect the overall quality of the concrete mix. In fact, it enhances the mix by providing better strength, yield, and durability.
Fiber Resa is a glass fiber mesh reinforcement used in waterproofing systems to prevent cracks and delamination, ensuring membrane durability in high-stress areas.
It’s compatible with cementitious, polymer-cement, and liquid membranes; however, always refer to system-specific guidelines.
Embed it into the first wet membrane coat, ensuring full contact and overlap of joints. Apply a second coat to fully seal the mesh.
Overlapping by at least 50 mm is advised to ensure continuity and avoid membrane weaknesses.
Yes—it resists UV exposure and chemical degradation, especially when fully embedded under the top membrane coat.
Absolutely—suitable for internal wet zones like bathrooms and external areas exposed to weather or thermal movement.
No—being lightweight and thin, it doesn’t significantly impact overall membrane build-up or tile screed thickness.
Rolls typically measure 1 m × 50 m (50 m²). Estimate coverage based on the plan area, plus 10–15% extra for overlaps and cuttings.
Yes—cut to size using sharp scissors or knives, ensuring edges are clean before placing.
Yes—cut squares or strips to reinforce corners, pipe penetrations, drains, and junctions for added waterproofing security.
