G&W Mortar

Product Description

G&W Mortar is an alkali water-based acrylic polymer micro-cement mortar composed of powder-type garnet which is high strength aggregate, white cement, and special soluble polymer emulsion.


Application

1. Crack Repair
2. Bonding with new and Existing Concrete
3. Tunnel Lining
4. Deck Coating
5. Road/Pedestrian Markings
6. Parking Garage Structures

1. Mixing equipment: Hand mixer, sieve.
2. Gauge: Scales.
3. Application equipment: recommended shotcrete/spray, trowel, brush.

1. Excellent chemical resistance
2. High compressive and flexural strength
3. Low conductivity
4. Thin coating is possible and high abrasive resistance
5. Easy application

1. Project site surface must be cleaned with high-pressure water jet cleaner.
2. Measure 1 lb of Type A(powder) and .17~.19 lb of Type B(binder).
3. Amount of Type B may vary depending on temperature and humidity.
4. Be sure to mix Type B within the specified range to ensure quality application.
5. Use brush if it used as mortar adhesive. (To protect defection of garnet)
6. Dampen concrete surface with water or Type B before application to ensure that concrete does not wick away moisture from mortar mixture in hotter weather.
7. Apply the mortar using exclusive shotcrete/spray equipment, trowel and brush etc.
8. Protect the surface from wind or direct sunlight after application.
9. Curing time - 1 hour *curing time is based on at or under 78°F

1. A sufficient curing is required under the temperature below 50°F.
2. In case of any condensation on surface, dry the surface using heater, fan, air compressor or portable burner.
3. In case of hot-weather concreting on dried surface, spray refined water or liquid to prevent the mortar from drying too rapidly.
4. Limit the amount of mixed material at normal temperature so that it can be applied within 30 minutes.
5. Do not use if powder hardens or liquid freezes.
6. Application should not be done below 41°F.
7. As the viscosity varies depending on temperature and humidity, keep agitating to prevent the aggregate from being segregated in a low viscosity, and add Type B within a mixing ratio allowable before agitating the material in high viscosity.
8. Protect surface from external impact, rain or direct sunlight for at least 48 hours after application.

1. Refer to instruction on storage of powder or liquid-type material for further details. If any problems persists, contact the manufacturer.

1. In the event any discrepancies between the specification and work environment, consult the manufacturer or designer before application.
