RE-URH Mortar

Product Description

RE-URH is a high quality polymer cement mortar composed of dry mortar mixed with rapid set cement and a liquid binder from a water based acrylic co-polymer. It is typically used for emergency repair conditions where immediate strength is needed, such as filling concrete cracks and restoring damaged concrete.

Application

1. Crack Filler
2. Emergency Repair

1. Mixing equipment: Hand mixer, electrical power mixer.
2. Gauge: Scales.
3. Application equipment: Trowel.

1. PH12 ±1
2. High Early curing strength and emergency repairing.
3. High Adhesion with existing concrete.
4. High workability and durability and weather ability.

Directions

1. Measure 1lb of Type A and .16 - .18 lb of Type B in each container.
2. Amount of Type B may vary depending on temperature and humidity.
3. Mix Type A and B sufficiently and apply as soon as possible.
4. Dampen concrete surface with water or Type B before application to ensure that concrete does not
5. wick away moisture from mortar mixture.

1. A sufficient curing is required under the temperature below 50°F.
2. In case of any condensation on surface, dry the surface using a 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 freezes.
6. 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 a high viscosity.
7. Protect the surface from external impact at least for 24 hours after application.

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

1. Those not instructed in specifications may follow standard concrete specifications.
2. In the event of any discrepancies between the specification and work environment, consult the manufacturer or designer before application.
