ABAGARD CR-300

SURFACE PREPARATION

Concrete should be cured for a minimum of 28 days prior to coating. The moisture content of the concrete should be below 4%. All surfaces should be clean, dry and free from curing compounds, release agents, trowelling compounds, surface hardeners, efflorescence, grease, oil, dirt, old coatings and loose or disintegrating concrete. All poured and precast concrete must also blasted, wire brushed or acid etched to remove laitance. Cracks, holes and honeycombs must be repaired prior to application.

MIXING

Open containers Component B and add entire contents to Component A. Mix thoroughly with an electric stirrer, taking care to entrain as little air as possible. Always mix such amount that shall be just sufficient to be used up within 30 minutes. Do not dilute the mixture.

Surface preparation shall not take place in following conditions:

- At temperature below 10 ºC.

- When the surface temperature is less than 3 ºC above dew the point.

APPLICATION

Material is supplied in two containers as a unit. Always mix a complete unit in the proportion supplied. Once the unit has been mixed it must be used within the working pot life specified.

Combined entire contents of curing agent (part B) with base (part A) and mix thoroughly with slow speed power agitator (max. 300 rpm). Mix thoroughly for 2-3 minutes, scraping the container bottom and side to assure complete mixing. There is no induction or waiting time required after mixing before application.

The exothermic characteristic of epoxy curing reactions may cause rapid temperature rise of mixture, which result low workability of material. To obtain longer workability, the mixed adhesive may be divided into portions.

The material is applied using a plastering trowel in a maximum layer thickness of 4 mm in one work step. The application can carried out in multiple layers.

- In hot climate, material temperature should be 20 to 25 ºC prior to mixing; otherwise pot life      becomes very short.

- Do not thin for any reason

- There should be no standing water on concrete surfaces.
