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:
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.
Mix proportions:
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.
Coverage
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.
Notes:
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.
G4 Pond Sealer Clear
G4 Pond Sealer is a moisture cured polyurethane which forms a non-porous seal on concrete rendered ponds, G4 pond sealer uses the moisture in the air and the render to harden, G4 pond sealer can be applied to slightly damp surfaces, but it is important that the render is sufficiently dry to be porous so as to enable the first coat of G4 pond sealer to bond and obtain a mechanical grip, G4 pond sealer can be applied in poor weather conditions, high humidity and at temperatures down to zero degree’s.
Koi Pond Construction Materials
As a general rule the pond should be constructed to be structurally sound since the G4 pond sealer only provides the waterproof seal, on no account use a P.V.A based sealer to seal or prime any surfaces, these materials can contain ammonia and also stop the G4 pond sealer from adhering to the render.
Ponds will normally be constructed with either brick, lightweight block or concrete block and then rendered, it is not necessary to add waterproofing agents to the render mix as this will increase the density of the render and can inhibit G4 pond sealer penetration, if a waterproofing agent has been used, simply rub down the surface with an abrasive to obtain a key.
If a fibre is used to give strength to the render it is necessary to burn off or sand down any fibres that are on the surface, as any fibres that protrude will cause leakage, G4 pond sealer will not bond to the fibres.
The cement render should be trowelled to an even surface but not to a smooth dense plaster like finish since this prevents the penetration of G4 pond sealer, new render should be kept damp for the first three days and then allowed to harden for 21-28 days depending on conditions.
G4 Sealer is an excellent sealer for brickwork, but below the waterline the brick should also be rendered. The reason is that while the G4 Pond Sealer is able to seal hairline cracks G4 Pond Sealer is not capable of bridging larger joints, cracks or holes.
G4 Sealer Method of Application
Apply the first coat of G4 sealer by brush, a roller can be used but it is necessary to avoid puddling of the G4 sealer on the base, it is best to use a brush, allow the first coat of G4 sealer to become finger tacky ( like cello tape ) or dry enough to walk upon carefully, approximately 45-60 minutes depending on humidity, then apply 2nd coat of G4 pond sealer, when second coat of G4 pond sealer is finger tacky apply third coat of G4 sealer, no longer than 4 hours should pass between coats, if a colour is used, then use 2 coats of standard and 2 coats of colour, G4 sealer is mechanically hard after 24 hours but must be given 72 hours to chemically cure, after which the pond can be washed down with plenty of water, drained, and can then be filled.
We strongly recommend that you mix Black Knight Wizard Fibre or some similar fibre into the render mix. This will help prevent the frost cracking the render in winter and give additional strength to the structure.
G4 Sealer Clear Application
Apply first coat of G4 pond sealer Clear by brush, a roller can be used but it is necessary to avoid puddling of the G4 pond sealer Clear on the base. Allow first coat to become finger tacky or dry enough to walk carefully upon, approximately 45-60 minutes depending on humidity, then apply the second coat of G4 sealer Clear. When second coat is finger tacky apply Third coat. No longer than 4 hours should elapse between coats. Normally 3 coats of G4 sealer Clear is sufficient to build a continuous surface film but on very porous substrates a 4th coat of G4 sealer Clear may be required, apply as instructed above.
G4 Colour Application
The system is slightly different. When using G4 Sealer Colour the first two coats must be G4 Sealer Clear. This is because G4 Pond Sealer Clear provides the maximum non-porous seal and adhesion.
Follow the application instructions as detailed for G4 Sealer Clear but the last two coats will be G4 Pond Sealer Colour. G4 Pond Sealer is mechanically hard after 24 hours and workable on some 6 hours after final application. However, 72 hours must elapse for full chemical cure, before washing down the G4 Pond Sealer with copious amounts of clean water. This water should be drained off. The koi Pond can then be filled. Consumption of G4 Pond Sealer will vary slightly according to the porosity of the substrate.
G4 sealer Clear – 3 coats = 550g per sqm for the three coats (approximately 185ml per squ. metre)
G4 sealer Coloured – 2 coats of Clear = 410g per sqm for 2 coats (approximately 205ml per squ. metre)
G4 Pond Sealer is available in Standard Clear, Black and Green.
If rain is expected make provision for covering the coated area, since water can damage the G4 pond sealer during the curing process. As soon as it is superficially dry water should not affect G4 pond sealer
Impermax Humidity Primer
It is not recommended to apply Impermax Aqua membrane directly on surfaces which may contain moisture or on damp surfaces, or humidity content, either on the surface or trapped underneath.
Humidity creates two important problems in treatments:
In case of damp surfaces, or if there is suspicion of humidity, it is imperative to pre-treat the area with Impermax Humidity Primer.
The quantity of Impermax Humidity Primer should be approx., 200 to 300 grams per square meter.
It is recommended to use Humidity Primer in most situations. Impermax can be applied even in cases of low temperatures (< 5ºC) and high relative humidity’s, obtaining very short cure times in combination with our PUR Cat additive.
Usage:
5 kg is sufficient for approx. 16.6 m²
Impermax Aqua Liquid Pond Paint
Impermax Aqua is an ideal liquid rubber pond liner suitable for a host of situations and surfaces that is simply painted on.

2kg covers 1m2
For Vertical sides add thixotropy
Impermax Aqua Application Guidelines
Product must be applied in quantities ranging 1.5 up to 2 kg/m2, resulting in a membrane thickness of 1.4 to 1.9 mm.
Ideally, it must be applied in 2 separate coats, best in different colours (assuring enough quantity is applied in each layer).
It is important to mix the product well before its application with an electric mixer, at low rpm (avoiding that too much air enters the resin). It is also necessary to let the product rest for a few minutes so that air bubbles disappear.
It is recommended to use Humidity Primer ( 200g per square meter) in most situations. Impermax can be applied even in cases of low temperatures (< 5ºC) and high relative humidity’s, obtaining very short cure times in combination with our PUR Cat additive.

Impermax Geomax Geotextiel – 30cm x 100m
Geomax Geotextiel reinforcement. A special nonwoven, made of synthetic fibre, specially developed for use in conjunction with Impermax (and its elasticity). This is optimally suitable for places (eg corners, gaps, floor drains) where increased protection is necessary.
This cloth minimizes the effect of self-distribution of the product and thus ensures that a corresponding thickness is reached quickly.
Main applications: IMPERMAX internal layer to protect against damage caused by corners, sharp objects, edges, etc to reduce the effect of self-distribution, for example, when processing steep / vertical surfaces as protection from below, when IMPERMAX on uneven surfaces is processed.
Available in 2 versions: as reinforcement (GEOMAX) or as superior /inferior protection of membranes, and drainage (GEOMAX PROTEC).-
Geomax is available in small width (30 cm), ideal to treat wall/floor areas, and when preparing areas before waterproofing.
Geomax is a thermo-welded Geotextile fabric used for reinforcement with Impermax Waterproofing Systems. It has a weight of 80 grams per sq. m. The Geo has to be fully saturated with the wet Impermax Liquid. The 30cm wide roll is ideal for the details- where the base of the pond meets the vertical. This is a critical area/ junction -and should be reinforced using 15cm width on the vertical and 15cm width on the Base. If the cement /screed if badly cracked then reinforce the total area with the 1m wide reinforcement.
Impermax solvent 4 kg
Impermax Solvent is ideal in situations when porous materials such as cementing, masonry etc… it is recommended to apply a first layer of Impermax diluted with the Rayston solvent in a proportion of 5 to 10%.
When the porous materials are saturated, it is then possible to apply the liquid membrane normally.
Ideally, this first application should be done at a rate of 0.5 kg / m2
This product can also be used to dilute Impermax (5 to 10%) for airless application.
