Black Knight Wizard Fibre
The easy to use cement additive that makes your pond smoother, stronger and crack-resistant.
Building a concrete pond has never been so easy.
Black Knight Wizard Fibre has been in use for decades in specialised architectural and construction projects where very high performance is required to withstand sustained stresses or harsh conditions and where long service is important.
Wizard Fibre is a very fine glass fibre designed specifically for mortar or concrete reinforcement. It has been in use for decades in specialised architectural and construction projects where very high performance is required to withstand sustained stresses or harsh conditions and where long service is important.
Why use Black Knight Wizard Fibre ?
Allows a much stronger mix, leading to a smoother crack-resistant finish that is safer for the fish:
- Saves money
- Increases workability, making it easier to apply
- 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
- Wizard Fibre and Concrete Ponds
The addition of Wizard Fibre has several long-lasting benefits, with the bonus that it is very easy to use. The fibre matrix and the fact that there is a high cement content means that the mix is very sticky but creamy in texture. It flows and adheres to the wall much more easily than a traditional mix. This brings the practice of concrete pond-building within the scope of the average hobbyist, thus saving a considerable amount of money.
When the final Wizard render has set and dried it can be painted with a proprietary pond paint. The special characteristics of Wizard ensure that it disperses evenly in the mixer. The product appears to be in flat strips but when water is added and it is subjected to the action of the mixer, all of these strips break into much finer strands. As these are so fine they do not present any kind of hazard if some of them are protruding from the final finish and therefore they do not require any further attention.
A well constructed pond with a Wizard Fibre render and a good quality pond paint could last a lifetime.
1 – 2% fibres added to the total mix by weight.
3 parts of building sand to 1 part cement.
We recommend the use of a mortar plasticiser in the mix (available at builders’ merchants) because it makes application easier.
A 1kg pack of Wizard Fibre can cover 8 – 18sqm at 5mm thick.
Typical mix proportions:
5 litres cement, 15 litres sand, 225 – 450g fibres.
The addition of fibre to the mix will improve workability up to about 90g per litre of cement and will decrease above this figure. Maximum crack resistance and strength is achieved at about this level. We suggest you experiment on a test area before you begin the job.
Allow extra time in the mixer for fibre dispersal. We suggest a minimum of 80 drum revolutions.
Do not attempt to render in hot, direct sunshine. The mix will dry out rather than cure, and it will spoil. Do not apply in frosty conditions.
This product should be applied only to surfaces that are sound and stable.
