Product Description

Resene AquaShield is a high mineral content super hydrophobic, water repellent coating for application on most porous building materials to impart water shedding properties. It combines the water repellent properties of silicones with a special surface microstructure considerably reducing the contact area for water and dirt. The result: dirt particles adhere loosely and are more easily carried away by raindrops, leaving a dry and attractive facade. Ideal for highly stressed weather-exposed facades. Also available in a Resene Cool Colour. NB. Resene Cool Colours need to be clearly identified in both the product specification and colour schedule to ensure correct tinting is applied.

Technical and Environmental Benefits

Resene Aquashield has been certified by Environmental Choice NZ as well as independently reviewed by EnviroSpec for its points contribution potential in Green Star NZ and Homestar building rating systems. Unwanted paint and paint containers can be returned to the Resene PaintWise paint and paint packaging recovery programme. Returns are donated to community groups, sent to solvent recovery, packaging is recycled and other paint goes into covering graffiti and research on alternative uses. Cool colours reflect more heat than standard colours, reducing stress on the paint, substrate and building, reducing heat transference inside and potentially helping reduce the need for air conditioning, all other design features of the building being equal. Additional benefits include:

• Very high water repellent properties.
• Excellent weather resistance.
• Allows the substrate to breathe.
• Improves fungal resistance of coated surface.
• Attractive mineral flat appearance.
• May be applied over a wide range of temperatures.
• Compatible with a wide range of coatings - may be applied over most existing coatings and may be recoated with most coatings.
• Tinted with non VOC tinters

Manufacturer and Supplier Information - Resene Paints Ltd

Resene started its quest towards more sustainable practices in the 1950s when it introduced waterborne paint. In 1996 Resene became the first New Zealand paint company to offer an extensive range of Environmental Choice approved products, Resene has since continued innovating in this space. In 2007 Resene Zylone Sheen VOC Free was introduced, and more recently Non VOC tinters have been introduced. The Cool Colours range provides exterior paints formulated to reflect solar radiation that would normally be absorbed. This is claimed to reduce substrate stress, improve paint longevity, and can help reduce heat absorption through building fabric which in turn could mean less air conditioning requirements. Resene also operates the PaintWise recycling programme, which includes a world-first" mobile paint collection and recovery

Application and Purpose

Typical uses: Brick, concrete block, fibrous cement, natural stone, poured concrete and stucco.

Application:
Resene Aquashield may be applied by brush, roller or airless spray. Recoat after two hours under normal conditions. 

Limitations:
1. Drying is slowed by low temperatures and high humidity.
2. Product properties are affected by high levels of tinter, therefore only a limited range of colours are offered.
3. Hydrophobicity, especially of tinted product, increases with time. Requires one month of direct weathering to achieve full hydrophobicity.
4. Colours will lighten with exposure. Care must be taken when touching up.
5. Avoid excessive film builds as it changes the surface microstructure and water repellency.

Installation and Maintenance

Resene products are guaranteed to provide film integrity and adhesion for the expected life of the paint system. Maintenance: Avoid cleaning the paint finish until at least four weeks after application time to ensure it has had sufficient time to fully develop its properties. Keep any cleaning to a minimum to avoid damaging the paint film. Follow the care and cleaning instructions in the Resene Caring for your paint finish brochure.
