Impermax liquid pond liner is a revolutionary development for professional pond construction!

The 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 during winter. 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).

2 kg covers 1m2

25 kg drum - Sufficient for approx. 12.5 m² with a membrane thickness of 1.4 - 1.9 mm. This corresponds to a coat of 2 - 3 layers.​

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 - 3 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.
