Product Description

Resene Limelock is a new preparatory coating used for the curing and sealing of cementitious substrates. It promotes cure by producing a water barrier, which unlike traditional curing membranes, may be over coated with waterborne finishes at any stage. Its ability to cure and seal the substrate eliminates the need to leave the plaster to cure for seven days before painting. When dark, heat absorbing topcoats are planned, it is still prudent to wait seven days before painting. Resene Limelock traps free lime in the cementitious substrate protecting the paint finish against the appearance of unsightly lime staining, and providing a perfect base for subsequent Resene finishes.

Technical and Environmental Benefits

Resene Limelock 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. Additional benefits include:

• Promotes early cure of fresh cementitious surfaces minimising downtime between the completion of plastering and commencement of painting.
• White pigmentation increases the albedo of the system to retain moisture.
• Seals in free lime to protect against the unwanted appearance of lime staining.
• Good adhesion to fresh cementitious substrates.
• Provides an excellent base for a wide range of Resene coatings.
• An Environmental Choice approved product.

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:
Cementitious surfaces, including concrete, render, stucco, and thin layer polymer modified plaster.

Application:
Resene Limelock may be applied by commercial grade knapsack sprayer, spray, long pile roller or brush.

Limitations:
• Do not apply at temperatures below 10°C or when it is liable to drop below 10°C during the drying period.
• Resene Limelock is designed to be overcoated.
• Resene Limelock is considered to be part of the surface preparation process and should be applied as soon as possible over plaster systems to achieve maximum potential.

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.
