How does Leakmaster LV-Z help seal against water?
It is a water-swelling sealant that swells approximately 2 times in volume as a result of distilled water absorption and swelling mechanisms, supporting water sealing without losing rubber-like elasticity.
Can Leakmaster LV-Z be applied when the surface is wet?
No. When the surface is wet, Leakmaster LV-Z is not suitable.
What is the recommended use temperature range?
Use at a temperature between 41°F (5°C) and 104°F (40°C).
What are the storage and shelf life requirements?
Store in a cool, dark and dry place below 90°F (32°C). Use within its shelf life of 12 months after the production month and year shown on the cartridge.
Are there placement requirements for cast in-situ concrete joints?
Keep a minimum of 100 mm concrete coverage on both sides of the Leakmaster LV-Z position when used for site formed concrete joints.
What are the basic application steps for the cartridge?
Break the moisture-proofing aluminum foil on the top of the cartridge, cut the nozzle at the appropriate position, set the cartridge to a caulking gun, and apply continuously without a break to the place to be sealed.
