Redwop Crack Filler is a high-performance, moisture-curing sealant engineered for long-lasting crack repair and prevention in concrete, masonry, stone, and tile surfaces. Its low-viscosity formulation penetrates deep into fine fissures and gaps (0.5 mm to 10 mm), forming a flexible, waterproof barrier that resists abrasion, freeze-thaw cycles, and chemical attack.
Key Features & Benefits
With excellent adhesion to concrete, stone, tiles, and metal, Redwop Crack Filler bonds cracks seamlessly while bridging minor movement thanks to its elastic behavior. It cures a resilient skin, delivering water resistance, UV stability, and resistance to oils and mild chemicals. This non-sag, non-yellowing formula minimizes surface blemishes and color distortion, making it ideal for visible repair zones and maintaining surface aesthetics.
Application Guide
Ensure the repair area is clean and dry—remove dust, debris, and loose particles. For hairline cracks, apply directly by cartridge or squeeze tube; use a spatula to press the filler deeply. For wider gaps, back-fill with closed-cell foam before applying the filler. Tool the surface smooth within 5 minutes to ensure a flush finish. Allow initial skin formation in 20–30 minutes, with full cure achieved within 24–48 hours depending on depth and humidity. No primer is needed for most substrates; apply temperatures between 5 °C and 35 °C. Clean tools with mild solvents before curing.
Ideal Applications
Redwop Crack Filler is perfectly suited for both residential and commercial repair works, offering high-performance sealing in a wide range of substrates. It is ideal for repairing hairline to medium-width cracks in concrete floors, pavements, and driveways, helping to restore both structural integrity and surface appearance. In interior environments, it is commonly used for fixing tile joints, wall cracks, and bathroom or kitchen areas where moisture protection is essential. Additionally, it performs exceptionally well on stone, masonry, and even precast surfaces, making it a go-to choice for terrace cracks, balcony joints, facades, and external wall repairs exposed to harsh weather conditions. Its flexibility and strong adhesion ensure long-term protection in both indoor and outdoor environments.
