Black Knight Wizard Fibre

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.
