Hypertectum Aqua

Introduction

Hypertectum Aqua is based on water-based polyurethane dispersion technology and protects structures in an environmentally friendly way, providing waterproofing in the most difficult conditions. It offers excellent resistance to ponding water and to harsh weather. Because it is aliphatic, it has excellent UV resistance and improves the energy performance of a building by lowering surface temperatures.

Technical properties

System build-up

Before you start

Clean with a high-pressure washer where possible. Remove oil, grease, wax, cement laitance, loose particles, mould-release agents and old cured membranes. Fill irregularities.

Concrete conditions: C20/25, moisture ≤5%, temperature 5–35 °C, RH <85%. Suitable substrates include concrete, fibre-cement, cement roof tiles, wood, galvanised steel and polyurethane foam.

Application

Mix at low speed (300 rpm). Apply by brush, roller or airless spray in two or more coats. Minimum waterproofing consumption >1.5 kg/m², depending on the project.

For non-demanding applications without standing water or negative water pressure, Aqua diluted with 15% water may act as its own primer. For demanding applications use Aqua Primer or Universal Primer 1K, or contact ETS Europe.

Where it goes

Polyurethane foam, roofs, light roofing (metal/fibre-cement), under-tile applications (wet rooms), protection of concrete against carbonation.

Limitations

Do not apply in extremely wet weather, when rain is imminent or at near-freezing temperatures. Unsound substrates require advice from ETS Europe; reinforcement may be possible in some cases.

Cleaning and storage

Clean tools immediately with water. Pack sizes: 5 and 12 kg. At least 12 months unopened in a dry place at 5–25 °C. Protect from frost; use as soon as possible once opened.
