12 months from the date of manufacture

The Product should be kept in dry conditions at a temperature of 5°C to 35°C. Storage at higher temperatures and high humidity may reduce the shelf life.

Mixed product: ~1.65 kg/l

When mixed, Parex High Build Protective Coating is classified as non-flammable.

Beware of condensation. Steel substrate temperature during application must be at least +3°C above dew point.

~45 Minutes

Initial usage: ~24 Hours (at 20^oC)
Full cure: ~7 Days (at 20^oC)

~6 Hours

Each 1.655kg unit will yield approximately 1 litre of mixed material.

CONCRETE / MASONRY / MORTAR / STONE

Concrete and mortar must be at least 3–6 weeks old. Substrate surfaces must be sound, clean, dry or matt damp. Free from standing water, ice, dirt, oil, grease, coatings, laitance, efflorescence, old surface treatments, all loose particles and any other surface contaminants that could affect adhesion of the Product.

STEEL

Surfaces must be clean, dry, free from oil, grease, coatings, rust, scale, all loose particles and any other surface contaminants that could affect adhesion of the bonding agent.

WOOD

Substrate surfaces must be sound, clean, dry and free from dirt, oil, grease, coatings, all loose particles and any other surface contaminants that could affect adhesion of the Product.

POLYESTER / EPOXY / CERAMICS / GLASS

Surfaces must be clean, dry, free from oil, grease and any other surface contaminants that could affect adhesion of the Coating.

CONCRETE / MASONRY / MORTAR / STONE

Substrates must be prepared mechanically using suitable abrasive blast cleaning, needle gunning, light scabbling, bush hammering, grinding or other suitable equipment to achieve an open-textured, gripping surface profile.

STEEL

Surfaces must be prepared mechanically using suitable abrasive blast cleaning, grinding, rotating wire brush or other suitable equipment to achieve a bright metal finish with a surface profile to satisfy the necessary tensile adhesion strength requirement. Avoid dew point conditions before and during application.

WOOD

Surfaces must be prepared by planing, sanding or other suitable equipment.

POLYESTER / EPOXY

Surfaces must be prepared by abrading using suitable equipment.

CERAMICS / GLASS

Surfaces must be prepared by abrading using suitable equipment. Do not apply to siliconised substrates.

ALL SUBSTRATES

All dust and loose material must be completely removed from all substrate surfaces before application of the product by vacuum / dust removal equipment.

Parex High Build Protective Coating base resin component is supplied in a container which is large enough to receive the hardener component and act as the mixing vessel.

Pour the entire hardener component into the base container and mix using a slow speed high torque drill with a Mortar Stirrer.

Mixing should be continued for two minutes to achieve a uniform consistency and colour.

Apply the Parex High Build Protective Coating as a single thick coat using a stiff bristle brush.

Do not attempt to brush out the applied material.

The applied thickness of 300 microns may be monitored using a simple thickness gauge to check the application during the work.

All tools and equipment should be cleaned with Sika® Thinner C.

Hardened Parex High Build Protective Coating may only be removed mechanically.
