tesa Sugru moldable silicone putty 8-pack (3.5g) — black & white, waterproof flexible adhesive for repairs

tesa Sugru is a hand-moldable silicone adhesive putty that sets into a flexible, waterproof rubber used for fixing, mounting, sealing and creative DIY projects indoors or outdoors.

Lightweight and versatile, this 8-pack of Sugru (3.5 g each) includes black and white colours ready for quick repairs, custom grips, or decorative accents. The material is kneadable at room temperature, adheres to many common surfaces and cures into a durable, weather-resistant silicone in 12–48 hours. Because it is non-runny and formulated to be skin-friendly, Sugru works well for household fixes, classroom projects and crafting with kids aged 3 and up.

How does Sugru bond different materials?

Sugru adheres mechanically and chemically to a wide range of substrates without specialized tools. It forms a strong, flexible bond to metal, glass, ceramic, plastics, wood and textiles once cured into silicone rubber.

• Works on metal, glass, ceramic, many plastics, fabric and wood
• Supports light loads up to about 4.4 lb (2 kg) when shaped appropriately
• Sets to a flexible, non-cracking silicone that moves with the object
• Does not require primers for most household surfaces

What is the setting time and how should I prepare surfaces?

Plan for a two-step process: shaping then curing. Knead and shape Sugru, apply to clean, dry, grease-free surfaces, and allow initial skin-setting in minutes; full cure happens in roughly 12–24 hours, with thicker or load-bearing builds taking up to 48 hours.

• Clean surfaces with isopropyl alcohol or soap and water; dry thoroughly
• Knead the putty for 15–30 seconds until uniformly coloured and pliable
• Press into place and shape; avoid moving the piece during cure time
• Allow extra curing time for thick or weight-bearing applications

Is Sugru safe for children and outdoor use?

Sugru’s non-runny, skin-friendly formulation makes it suitable for supervised projects with children aged three and older; it’s designed to be user-friendly rather than a hazardous liquid adhesive. Once cured, the silicone is waterproof and resistant to sun, rain and temperature changes—suitable for many indoor and outdoor applications.

• Non-toxic, skin-safe handling for ages 3+ under supervision
• Cured silicone stands up to water, heat and UV exposure
• Ideal for classroom crafts, family repairs and garden fixtures
• Not intended for internal medical or load-critical structural use

How can I use Sugru for everyday fixes and creative projects?

Sugru is both a repair tool and a creative material: form grips, mount hooks, seal cords, repair chipped surfaces, and customize items with colour and texture. Its moldability lets you create bespoke solutions that rigid adhesives can’t match.

• Create custom cable grips, non-slip handles and feet for electronics
• Patch minor cracks, seal around fixtures, or mount lightweight hooks
• Build decorative accents, personalised tags or craft shapes
• Use outdoors for small repairs like plant pot feet, gutter guards, or garden labels

Who is this for? Homeowners, crafters, teachers and DIY hobbyists who want a safe, easy-to-use, multi-surface adhesive that doubles as a modelling material will find this Sugru 8-pack convenient and versatile. It’s ideal for anyone looking to repair everyday items, add protective or functional silicone features, or experiment with custom modifications without specialized equipment.
