Corroless ACO Pour & Roll is a solvent free, two pack polyurethane for floor, wall and steel coating.

Features & Use

• Designed for application to steel and concrete, for heavy duty flooring, tank coating, grouting and encapsulation
• Rapid drying and curing characteristics

Surface Preparation

• All surfaces to be coated should be dry and cleaned as necessary to remove all oil, grease, salts, weld flux or other contamination. Where necessary, remove weld spatter and grind smooth all sharp edges and weld seams
• Steel: blast clean to minimum Sa2½ (ISO 8501-1:2007), surface profile depth 75-100µm. Mechanical tools may also be used providing a profile of minimum 75µm. Do not polish the steel surface
• Concrete: remove all laitance and other contaminants by most appropriate methods. Ensure the concrete is dry to a reading of <16% on the Wood Moisture Equivalent (WME) scale. Prime with Corroless ACO LV Sealer

Mixing

Mix only in the proportions stated, mixing each component individually then together using a mechanical agitator. Activator must be added to base and thoroughly mixed to ensure an even mix throughout the container – at least 2 minutes mixing time is recommended. Care must be taken to avoid unmixed material being left on sides and bottom of can. Decanting mixed material into a plastic container and further mixing is recommended. Plastic container may be recovered for further use when coating has cured.

Thinner

Do not thin

Cleaner

Axalta Thinner Fast Industrial TH120 (formerly called No.4 Thinner)

Application Conditions

Do not apply when rain, mist, sleet or snow are imminent. Normal application requires relative humidity below 80%. To avoid risk of condensation, application should be performed only when the steel surface temperature is at least 3°C (5°F) above the dew point. Application at temperatures below 1°C (33°F) must be carefully monitored, since the possible presence of ice on the surface (or in pores, in the case of concrete) will result in poor performance.

Application Method

Apply using trowel or squeegee. De-aerate thickly applied floor coating whilst still wet using a spiked roller.

Product Notes

• Activator contains isocyanates – refer to Safety Data Sheet
• Not normally overcoated – consult Axalta Coating Systems for advice if overcoating is required
• In-service temperature limits: Wet – 0 oC to 70oC depending on solution; Dry – minus 20oC to + 120oC continuous
• In order to comply with WRAS certification, a minimum cure time of 14 days at 7 oC is required before contact with drinking water
