Impermax Aqua Liquid pond Liner
Impermax Aqua
Impermax Aqua is an ideal liquid rubber pond liner suitable for a host of situations and surfaces that is simply painted on.
The product is based on polyurethane (drinking water approved according to EEC directive 98/83/CE) and provides a smooth, seamless membrane.
The finished membrane is constructed in various layers with the resulting liner being in excess of 1.4-1.9mm thick almost twice the thickness of conventional sheet liners and with the similar finish to fibreglass.
As Impermax Aqua is a liquid pond liner, it is painted on and will be as durable as conventional pond liners once cured, being highly elastic and able to withstand expansion, contraction or slight movement in the support structure without compromise to its integrity.
Impermax Aqua liquid pond liner is the new era of pond lining, its easy to apply with brush or roller gives a seamless finish, applied in 2 coats to achieve maximum strength and durability, available in a series of colours
Impermax Aqua Liquid rubber is a new single component, high performance waterproofing material, based on Polyurethane, certified according to EEC Directive 98/83/CE, and which can be in direct contact with drinking water for human consumption.
It can be easily applied on different kinds of surfaces used in hydraulic infrastructures such as concrete, mortar, ceramics, fibreglass reinforced polyester, etc.
Curing time: 4-6 hours in the summer, 12-24 hours. Apply at least 3 to 4 layers to obtain a membrane thickness of 1,5 to 1,9 mm (2 kilo per m²). It is recommended to use Humidity Primer in most situations.
Economic and easy to apply, it delivers a jointless continuous membrane which totally adapts to the surfaces to be protected.
Extreme mechanical and chemical properties.
Certified according to EEC Directive 98/83/CE, so it can be in direct contact with drinking water for human consumption.
This membrane can easily be applied in spots which are difficult to access with other systems.
It is easy to obtain uniform thicknesses combining the product with geomax and our thixotropy agent, even in extremely steep or even vertical areas
Impermax Aqua can be applied even in cases of low temperatures and high relative humidities, obtaining very short cure times in combination with our PUR CAT additive.
Product does not require any blends or special primers (it is a one component product).
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 in most situations. Impermax can be applied even in cases of low temperatures (< 5ºC) and high relative humidities, obtaining very short cure times in combination with our PUR Cat additive.

G4 Pond Sealer Clear
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 Pond 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 Pond Sealer Method of Application
Apply the first coat of G4 pond sealer by brush, a roller can be used but it is necessary to avoid puddling of the G4 pond sealer on the base, it is best to use a brush, allow the first coat of G4 pond sealer to become finger tacky ( like cellotape ) 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 pond 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 pond 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 reccomend 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 Pond Sealer Clear Aplication
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 pond 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 pond sealer Clear is sufficient to build a continuous surface film but on very porous substrates a 4th coat of G4 pond sealer Clear may be required, apply as instructed above.
G4 Pond Sealer Colour Aplication
The system is slightly different. When using G4 Pond Sealer Colour the first two coats must be G4 Pond 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 Pond 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 pond sealer Clear – 3 coats = 550g per sqm for the three coats (approximatly 185ml per squ. metre)
G4 pond sealer Coloured – 2 coats of Clear = 410g per sqm for 2 coats (approximatly 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
