FEATURES & BENEFITS
• Easy to use 1:1 ratio by weight • Excellent adhesion to concrete, metal and most porous surfaces • 100% solids epoxy – solvent free, no VOC • No shrinkage once cured • Sag resistant – high build consistency, vertical and overhead work • Tolerant to moisture before, during, and after cure • Good chemical resistance for long-term protection • High abrasion and vibration resistance
• Patching and forming damaged precast and insitu concrete • Patching damaged concrete floors, tanks and pipes. • Patching of concrete floors under heavy load or impact. • Bonding concrete blocks, bricks, paving • Fabrication of concrete pipe intersections, risers etc • Underwater repair applications
TRADES & APPLICATIONS
Patching concrete tanks and pipes
Repair broken and spalled concrete
Refer to the Technical Data Sheets and MSDS for further detailed installation instructions and precautions.
Concrete must have a minimum of 7 days cure. Surface must be clean, sound, dry and free from any loose coatings/particles or surface contaminates such as grease, oil, chemicals, paint, rust or curing membranes.
Product is mixed by 1 part hardener to 1 part resin by weight. Thoroughly mix the epoxy resin and hardener by trowel blending on a flat surface or by hand mixing (kneading) using nitrile gloves. Larger volumes can by mixed using a mechanical mixer.
When thoroughly blended, material will be a uniform streak free grey colour. Do Not add water as it will lower all physical and adhesive strengths.
Pack by gloved hand (nitrile gloves) or trowel onto area or cavity to be filled to the desired thickness. Ensure epoxy is forced well into the substrate surface to ensure good contact with the host surface.
Avoid air entrapment (voids). Smooth off with a steel trowel and if required, lightly moisten surface only to aid finish.
To avoid potential shrinkage caused by exotherm the maximum layer thickness per application is 40mm.
Some repairs may require the use of formwork on one side to assist application i.e. corners or large applications.
