ABAGARD CR-40

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.

Surface preparation shall not take place in following conditions:

• At temperature below 20 ºC  
• When the relative humidity is greater than 80%
• When the surface temperature is less than 3 ºC above the dew point

APPLICATION

Material is supplied in two containers as a unit. Open containers component B and add entire contents to component A. Mix thoroughly with an electric stirrer with slow speed (max. 300 rpm) for 2-3 minutes, scraping the container bottom and side to assure complete mixing and take care to entrain as little air as possible. There is no induction or waiting time required after mixing before application. Always mix such amount that shall be just sufficient to be used up within 30 minutes.

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.
