Weicon Aqua Repair Stick

Weicon Aqua Repair Stick is an epoxy-based repair putty developed for rapid repairs in wet, damp, and underwater applications. Thanks to its ceramic-filled structure, it provides a shapeable repair solution for sealing cracks, holes, leaks, and seepage. Its putty form makes it easier to press and work the material onto the surface during application, allowing controlled use in maintenance processes. The 115 g packaging option is listed on official product pages, and the product is manufactured by WEICON, based in Germany.

Technical structure and key features of the Aqua Repair Stick
This product is a two-component, epoxy-based repair system filled with ceramic. According to the technical data sheet, the mixing ratio is 1:1 by weight, the mixed density is approximately 1.9 g/cm³, and the maximum gap-filling capacity is 15 mm. Its color, described as vintage white, and its modelling consistency provide an advantage especially in repairs that require shaping on the surface. After curing, it forms a hard structure and offers a permanent repair character.

Performance and durability features of WEICON Aqua
According to the technical data, the compressive strength is 55 MPa, the Shore D hardness is 70±3, and the adhesive strength is 5 MPa. Its temperature resistance ranges from -50 °C to +120 °C and can reach up to +150 °C for short periods. The thermal conductivity is 0.5 W/m·K, while the dielectric strength is at a level of 3.0 kV/mm. These values show that the product can be used not only for filling purposes but also in functional maintenance and sealing applications.

Application method and process conditions
Before application, it is recommended that the surface be made as solid and rough as possible. According to the technical documentation, dust, dirt, oil, grease, rust, and old residues may negatively affect adhesion, so surface preparation is important for application success. The required amount is cut off and kneaded until a uniform color is obtained, then applied to the crack or cavity. Before the material hardens, the surface can be smoothed with water or a damp cloth; after approximately 60 minutes, the repaired area becomes mechanically workable.

Areas of use, surface compatibility, and key advantages
This repair putty can be used for repairing cracks, holes, and leaks in petrol and water tanks, radiators, electrical panels, sanitary components, and swimming pools. It is also positioned as suitable for plumbing and heating systems, electrical equipment, marine applications, and various industrial maintenance processes. Its most notable advantages include the ability to be applied on wet and damp surfaces, curing underwater, creating rapid initial strength, and becoming suitable for drilling, sanding, or thread cutting after hardening. For this reason, it offers a practical and technically strong repair solution especially in maintenance areas exposed to water.

Safety and technical reference information
According to the safety data sheet, the product may cause skin irritation, serious eye irritation, and allergic skin reactions; it also carries a warning for long-term harmful effects on aquatic life. Therefore, protective gloves and eye-face protection should be used during application. The technical data sheet also includes ISSA Code 75.530.02/03 and IMPA Code 812923/24. Within this framework, the product stands out as a technically defined, ceramic-filled epoxy repair putty for underwater and damp environment repairs.
