Frequently Asked Questions (FAQs) About PAVATAPE 12
What is PAVATAPE 12 and how is it used?
PAVATAPE 12 is a double-sided butyl rubber tape used for airtight and water-tight sealing of junctions and overlaps in vapour control membranes and roofing membranes. Its elastic properties make it suitable for bonding membranes to a variety of surfaces without waiting for drying time.
What are the key characteristics of PAVATAPE 12?
• Material: Double-sided butyl rubber tape.
• Thickness: Around 3 mm.
• Roll length: 10 m per roll.
• Roll width: 12 mm.
• Box contents: 10 rolls per box. Available for purchase in single roll quantities from Unity Lime
At what temperatures can PAVATAPE 12 be applied?
• Minimum substrate and ambient temperature (with primer): -10 °C.
• Application temperature for tape: From +5 °C to +30 °C.
• Temperature resistance after installation: -40 °C to +100 °C.
Do I need to use a primer before installing PAVATAPE 12?
Yes. When applying PAVATAPE 12 to porous or woodfibre surfaces, such as PAVATEX boards, use a primer like PAVAPRIM or PAVABASE first to improve adhesion.
What surfaces is PAVATAPE 12 suitable for?
PAVATAPE 12 bonds well to both rough and smooth surfaces. It is particularly suited for connecting vapour control membranes to masonry, timber and other construction substrates when installed correctly.
How does PAVATAPE 12 differ from other PAVATAPE types (e.g. 75/150)?
Unlike PAVATAPE 75/150, which is a single-sided aluminium-laminated sealing tape for sealing board joints and penetrations, PAVATAPE 12 is double-sided and tailored specifically for sealing overlaps and membrane edges at smaller widths.
Where is PAVATAPE 12 typically used in building projects?
PAVATAPE 12 is ideal for airtightness detailing in roof, wall and floor assemblies where breathable/airtightness membranes overlap, especially in conjunction with PAVATEX insulation systems. It is also suitable for water-tight bonding of roofing membranes.
What are the main performance benefits of PAVATAPE 12?
• High initial adhesion for secure bonding.
• Elastic and durable seal that accommodates movement.
• No drying time needed, helping speed up installation.
• Suitable for multiple surface types, including rough and smooth areas.
How should PAVATAPE 12 be stored?
Store PAVATAPE 12 in a cool, dry place, protected from sunlight and humidity to maintain its sealing performance until use.
