How to Use
The following should only be used as a guide and the installer should apply all Australian Standards, BCA/NZBC requirements, and best practices when installing. Use ony 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 turps 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.
- Using the caulking gun, apply N-Mastic to the joint and tool if necessary.
- Mechanically fix joints where necessary.
Limitations:
- 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.
Handy tips
- Although N-Mastic is resistant to static pressures, a curing sealant is recommended where this is a critical factor.
Clean Up
- Spills and tools can be cleaned up with mineral turps.
