N-Mastic White
Selleys N-Mastic is a non-skinning polybutene-based compound. It will remain permanently soft and paste-like.
Features
- Non-hardening – remains permanently flexible to provide a lasting seal
- Good adhesion – adheres well to most substrates
- Moisture resistant – provides an excellent barrier to water vapour transmission
- Resists microbial attack
- Low shrinkage – avoids the risk of sealant pulling away from joint surfaces
- Wide service temperature range – withstands –40°C to +80°C service conditions

- Sealing concealed lap joints between plastics, metals, timber, glass, masonry and expanded foam panels
- Installation of cool rooms, prefabricated construction and gasket sealed windscreens to exclude draughts and water penetration through joints in materials
What materials is this product suitable for?
- Glass
- Masonry
- Metals
- Expanded foam panels
- Timber
- Plastics
Use only in a well ventilated area. Avoid contact with skin and eyes and breathing vapours.
- Surfaces to be sealed must be clean, dry and free from dust, grease and flaking paint.
- Clean surfaces with mineral turpentine and allow to dry.
- Cut nozzle supplied at an angle and to the required opening. Cut end off nipple on cartridge, fit nozzle and insert in suitable caulking gun such as Selleys Caulking Gun.
- Using the caulking gun, apply N-Mastic to the joint and tool if necessary.
- Mechanically fix joints where necessary.
- Due to the non-skinning, non-hardening nature of the sealant, N-Mastic should not be used in exposed joints where dirt pick-up or hand contact can be a problem.
- As N-Mastic is not elastomeric, it should not be used in areas subject to considerable dynamic stress.
- N-Mastic is not recommended for sealing lap joints in mobile homes, truck bodies, etc. as significant vibration and flexing occur during travel.
- Although N-Mastic is resistant to static pressures, a curing sealant is recommended where this is a critical factor.
- Spills and tools can be cleaned up with mineral turpentine.
