Black Knight Wizard Fibre
Black Knight Wizard Fibre allows you to smooth over and seal cracks in your aquatic environment, that would otherwise cause devestating leaks.
Product Information
Wizard Fibre contains very fine glass fibres that are designed for mortar or concrete reinforcement. A technique that has been used in other industries for years, this is completely aquatic safe and allows for a much stronger mix with a crack resistant finish.
Just add to your mortar or concrete to ensure a better workability that will be easier to apply, with a finished product that is far stronger and more durable, with a dramatically reduced chance of leaks occuring.
A 1kg can of Wizard Fibre can cover between 8 - 18 square metres at 5mm thick, making this great value for money, whilst being stronger than most sealant additives.
Key Features:
- Allows a much stronger mix, leading to a smoother crack resistant finish that is safer for the fish
- Far stronger, more durable and easier to use than polypropylene alternatives
- Dramatically reduces the likelihood of leaks developing
- High zirconia content offers superb alkali resistance
- Covers 18 square metres
