Henkel Polybit Polypoxy NF Repair Reactive, 3L, Reactive Epoxy Repair Compound

Henkel Polybit Polypoxy NF Repair Reactive 3L is a two‑component, moisture‑curing polyurethane resin kit designed to permanently repair concrete cracks and damage such as spalling, broken edges, and cavities. It provides strong adhesion to a wide range of substrates and is formulated for durability in harsh conditions, including high humidity and temperature fluctuations. The 3L kit is suitable for areas with foot or vehicle traffic and can be used on concrete, as well as compatible substrates like wood and metal.

Key features include a two‑component polyurethane resin system, moisture curing, rapid curing time, and strong adhesion to multiple substrates. It offers resistance to extreme temperatures, humidity, and chemicals, plus abrasion resistance for high‑traffic areas. It can be applied to wet surfaces and is suitable for structural repairs in areas such as columns, beams, balconies, decks, and driveways, including environments with seismic activity.

Surface should be clean, sound, and free of contaminants. Mix the resin and hardener as specified on the product label until a uniform, lump‑free blend is achieved. Apply to the prepared area using a suitable tool (trowel, spatula, or appropriate applicator) and ensure even coverage. The material cures quickly under normal conditions, forming a strong bond to the substrate. Follow with the recommended finishing and curing steps as described in the product guidelines for best results.

The product is designed to adhere well to common construction substrates, including concrete, wood, and metal, with the resin providing durable bonding onto these surfaces for crack repair, spalling repair, and edge restoration.

Yes. Polybit Polypoxy NF Repair Reactive is formulated for moisture‑curing and can be applied to damp or wet surfaces, which helps in repairs where ambient or substrate moisture cannot be fully removed.

The system is designed to withstand extreme temperatures and humidity and offers abrasion resistance for high‑traffic areas. It is suitable for environments subject to freeze–thaw cycles and seismic activity, providing durable, long‑lasting repairs in challenging settings.

Use appropriate personal protective equipment (PPE) such as gloves and eye protection, ensure good ventilation, and avoid skin and eye contact. Follow safe handling instructions and consult the SDS for hazard information. Store and transport the kit in its original packaging and keep away from children and ignition sources as recommended by the safety guidelines.

The product is described as having a very fast curing time. Cure duration is influenced by ambient temperature, humidity, surface substrate, and the amount of material applied. Higher temperatures and lower humidity generally accelerate curing, while colder conditions may slow it down.
