Opus Easyseal AC3 is a specially formulated clear acrylic resin polymer compound designed specifically for the initial curing of freshly placed concrete, combined with the added benefits of sealing, hardening and dust proofing the concrete surfaces. Opus Easyseal AC3 is a partially penetrative material that provides a permanent, non-degrading protective matrix to the concrete surface. The acrylic film is UV stable and once cured provides a durable elastic coating that protects against staining and subsequent dusting.

- Film is touch dry within 2-6 hours from application.
- Coating is fully cured in 24 hours and maybe trafficked.
- Provides a permanently hardened surface.
- Provides a durable, dust free surface.

Opus Easyseal AC3 is supplied ready for use and should not be diluted. Concrete should be sprayed with Opus Easyseal AC3 at the specified coverage rate immediately after surface finishing and when any free water has dissipated. The application should be affected by evenly applying a fine mist spray, from a low pressure sprayer unit. Care should be taken during application in high ambient temperature/windy conditions to avoid dermal and respiratory contact. Coverage rates should vary depending upon the intended use. See COVERAGE. A second coat may be applied between 4-24hrs following the initial application. Spray equipment should be dedicated for use with Opus Easyseal and must be thoroughly cleaned after use with solvent cleaner.
When required to provide effective curing to fresh concrete, Opus Easyseal AC3 should be applied at 5m2 /litre.
When required for sealing and dust proofing freshly cast concrete, the application should be 6-14m2 /litre.
When required for sealing and dust proofing mature concrete, the application should be 10-14m2 /litre.
Opus Easyseal AC3 Complies with the requirements of ASTM C 309-97. Type 1 Class B. When tested in accordance with ASTM C 156-95 Opus Easyseal AC3 applied at a coverage of 5m2 /litre, restricts water loss to not more than 0.55Kg/m2 of surface in 72hrs.
