The surface must be sound, dry, clean and free from grease, contamination, release agents, curing compounds and loose film. Remove all loose film, mill scale and rust. Best results are obtained by applying directly to blast-cleaned metal surfaces. However, where blasting is not possible due to cost or conditions, Interdur 8814 is designed to provide good protection on surfaces with less-than-ideal preparation. The minimum surface preparation for non-immersed conditions is St 2 (GB 8923-1:1998); for immersed conditions, the minimum is Sa 2 (GB 8923-1:1998). The above minimum surface preparation standards apply to recoating of previously blast-cleaned steel. If severely corroded surfaces remain after preparation, seal them with a primer before using this product. Ideal performance is obtained by direct application to surfaces blast cleaned to near-white metal.
Steel: blast clean new steel surfaces to near-white metal Sa 2.5 (GB 8923-1:1998); the blasted surface should have a sharp angular profile rather than a flat profile, with 38-62 µm.
Cement board: remove loose material and repair voids, then apply Interdur 8814.
Concrete floors: allow cast concrete to cure for at least 30 days; acid-etch and abrade to roughen smooth areas and remove laitance, then apply Interdur 8814 as a primer.
Galvanised steel: remove oil and grease with solvent or another suitable detergent, then wash thoroughly with water.
Old painted surfaces: check whether the old coating is lifting. If so, remove it; otherwise, abrade smooth areas and weathered epoxy surfaces with abrasive paper. Clean weathered epoxy and polyurethane coatings with GTA110, and apply a suitable primer to bare areas. For overcoating weathered alkyd coatings, thin with GTA007 thinner if thinning is required.

| Cleaner | Use a cleaning solvent that complies with local regulations. Consult the local representative for specific recommendations. |
|---|---|
| Interruption of work | Do not leave paint in hoses, spray guns or spray equipment. Flush all equipment thoroughly with International thinner. |
Mixed paint should not be resealed. If application is interrupted for an extended period, use freshly mixed material when work resumes.
| Cleaning | All equipment shall be cleaned with International thinner immediately after use. Periodically flushing spray equipment during the daily work is good practice. The frequency of cleaning depends on the quantity sprayed, temperature, spraying time and interruptions. All remaining paint and empty containers shall be disposed of in accordance with local laws and regulations. |

Advantages: - superior anticorrosive performance - suitable for salt water and fresh water immersion - low-temperature curing down to -18 °C - surface tolerance - good adhesion on damp surfaces - self-overcoating on steel and masonry substrates - fast recoating - high solids, high film thickness. Interdur 8814 may yellow if exposed, during application and curing, to combustion by-products from improperly vented fossil-fuel heaters.
For durable decorative surfaces requiring good gloss and colour retention, overcoat with the recommended topcoat.
Normally no thinning is required; however, in some extreme environments, a small amount (15% by volume or less) of International GTA110 thinner may be added, subject to local VOC and air quality regulations. Any solvent must be added only after the two components have been thoroughly mixed.
Note: VOC values are typical and for guidance only. They may vary with colour and general production tolerances.
The following primers may be used with Interdur 8814: Interdur 8803, Interdur 8804, Interdur 8806, Interdur 8807, Interdur 8809, Interdur 8810
