Plaster Bandage – Professional Plaster Bandage for Support Shells & Moulds

Premium Plaster Bandage for Professional Support Shells and Moulds

Plaster bandage is a high-quality, fast-setting plaster bandage with cotton gauze (17 threads), specifically developed for making support shells for silicone moulds, as well as for body casting, SFX applications and podiatry. This professional bandage combines fast processing (3–4 minutes), a creamy, supple feel and high strength once set – ideal for durable support shells and dimensionally stable constructions. Safe to move after 30 minutes, fully cured after 24 hours.

Key Benefits

• Fast processing: 3–4 minutes working time, only 5 seconds of immersion for optimum soaking
• Quickly safe to move: load-bearing and safe to move after 30 minutes, fully cured after 24 hours
• Creamy and supple: cotton gauze with 17 threads for easy modelling and a perfect fit
• High strength: α- and β-calcium sulphate hemihydrate for durable, dimensionally stable support shells
• Professional quality: Lohmann & Rauscher quality for reliable results
• Long shelf life: at least 4 years when stored cool and frost-free

Typical Applications

• Support shells for silicone moulds (trowel-on and brush-on moulds) in mould making
• Body casting and lifelike casts for art and medical simulation
• SFX and prosthetics: support shells for masks and special effects moulds
• Podiatry applications and medical models
• Props and set building for theatre, film and the entertainment industry
• Ornaments, sculptures and model making where dimensionally stable support is required

Technical Characteristics

Basic specifications:

• Composition: cotton gauze with 17 threads + α- and β-calcium sulphate hemihydrate
• Working time: 3–4 minutes at a water temperature of 20–25 °C
• Immersion time: approx. 5 seconds (until the air bubbles stop)
• Safe to move: 30 minutes
• Full strength: 24 hours
• Recommended water temperature: 20–25 °C
• Shelf life: at least 4 years when stored correctly

Processing instructions:

1. Take the bandage out of the packaging (cut into pieces for specific sizes if required)
2. Immerse in water at 20–25 °C
3. Hold under water for approx. 5 seconds, until the air bubbles stop
4. Take out of the water and squeeze the roll from the outside inwards
5. Use immediately: drape around the model and shape by hand
6. Allow 30 minutes to cure before moving, 24 hours for full strength

Processing tips:

• Use only clean water and clean tools
• Warmer water speeds up setting, colder water slows it down
• For support shells: build up several layers for extra strength
• Combine with trowel-on silicone moulds for optimum results
