Repair putty adhesive Tesa Sugru black 3 x 3.5 g – mouldable multi-purpose repair putty

Tesa Sugru black is a mouldable multi-purpose repair putty adhesive supplied as three 3.5 g portions. The soft, malleable compound can be shaped by hand and bonds to a wide range of materials including most plastics, metals, glass and ceramics. After curing it forms a flexible, rubber-like material that restores functionality, seals gaps and provides a durable, vibration-damping finish for household and light DIY repairs.

Advantages

The putty adheres to many common surfaces without primers and cures at room temperature to produce a permanently flexible, water-resistant finish. Its black colour integrates with dark materials and hides repaired areas. Supplied in three separate portions, it is convenient for small repairs and reduces waste. The cured material resists impact and abrasion while remaining slightly elastic, which helps joints and grips retain movement and cushioning.

Suitable for

• Repairing and reshaping worn handles, knobs and grips
• Sealing small gaps and cracks around fittings and fixtures
• Cable management and strain relief for cords
• Bonding and joining dissimilar materials in light household repairs

Key specifications

• Colour: black
• Form: mouldable putty
• Portion size: three portions of 3.5 g each
• Cures at room temperature to a flexible rubber-like material
• Water-resistant and impact-damping when cured
• Bonds to plastics, metals, glass and ceramics

How to use

Cut or break off one portion, knead the putty in your fingers until it is soft and uniformly coloured, then shape and press it onto the clean, dry surfaces to be repaired. Smooth edges by hand or with a damp tool and allow the repair to cure at room temperature; curing time depends on thickness but typically reaches handling strength within 24 hours and full mechanical strength after longer curing. Remove excess material before curing for a neater finish.

Usage recommendations

For best adhesion, ensure surfaces are clean, dry and free of grease or dust. Avoid using the putty on continuously submerged areas or on surfaces that require high-temperature resistance. For load-bearing applications, design repairs to distribute forces and allow adequate cure time before full use.
