Castlecoat SF is a solvent-free, tough epoxy coating that can be applied to most common construction substrates. It has excellent resistance to chemical attack, making it suitable for wall and floor coating and tank lining where a long-lasting, durable finish is required. Castlecoat can be applied by brush, roller or spray directly onto most clean, dry, non-porous substrates. Porous surfaces should be primed with Castleseal-2 before application of Castlecoat. Steel and ferrous surfaces should be grit blasted to SA2.5 standard.

+ = Resistant 0 = Not resistant. All chemical resistance measured at 25°C

All surfaces to which Castlecoat SF is to be applied should ideally be clean, dry and free from dust and loose particles. Priming porous surfaces with one coat of Castleseal Porous Surface Sealer will remove any surface moisture and enhance adhesion of Castlecoat. Steel and other metal surfaces should ideally be grit-blasted.

Steel surfaces that are subject to continuous immersion in aqueous solutions will benefit from a coat of Castlecoat Steelprime before being coated with Castlecoat SF. Fresh galvanising will require pre-treatment with mordant solution or phosphoric acid etch primer. Hard, shiny surfaces such as vitreous enamel should be abraded. Mix Castlecoat SF by adding all of the hardener to the Base and stir with a paddle mixer fitted to a slow speed drill until homogenous and free from streaks, (packs are pre-measured). Do not mix more than can be used in 60 minutes. Apply immediately by roller, brush or airless spray. Allow to cure for 24 hours before walking over.

Typical coating thicknesses of 400-500 microns (2 coats) are normally achieved with any of the above methods at 10 to 30°C. At lower or higher temperatures, greater or lesser film builds may result.

A minimum of two coats is required to give a continuous, pinhole-free surface. Multiple coats should be applied after 14 and within 18 hours of each other.

Vessels that may be attacked by the stored medium, e.g. concrete or steel tanks holding acids, will require extra coats to ensure continuity of the film. Metal vessels can be effectively checked for film continuity by spark testing.

Castlecoat SF is suitable for trafficked surfaces after 48 hrs.

Unlike conventional paints, Castlecoat SF is solvent free and may therefore be used safely in confined spaces without fire risk or undue operator hazard.
