| Carbon Steel | Sa 2½ (ISO 8501-1) | |
| Coated surface | A clean, dry and sound compatible primer. | |
| Stainless steel | The surface should be blasted with a non-metallic abrasive, | “Blast clean using an approved non-metallic abrasive |
| hand- or machine-sanded using abrasive paper or fibre discs, | to produce a sharp angular surface profile.” | |
to produce scratch marks on the surface.
| Galvanised steel | The surface should be clean, dry and have a suitable profile | Sweep blast with a non-metallic abrasive to produce a clean, |
| ° | a rough and uniform surface. | |
| Concrete | Dry abrasive blast clean to SSPC-SP 13 / NACE No. 6. | |

At the above temperatures, protective performance is unaffected, but appearance may be affected.
Note: this coating can withstand different immersion temperatures, depending on the specific chemical and whether immersion is continuous or intermittent. Heat resistance is affected by the coating system as a whole. When used with other coatings, ensure that all coatings in the system have similar heat resistance.
Depending on the actual exposure conditions in service, this product may be used with various primers and topcoats. Some reference systems are listed below. For specific systems, contact JOTUN.

In some markets, the stated shelf life may be shortened to comply with local legal requirements. The above is the minimum shelf life; thereafter, testing is required to confirm quality remains acceptable.
For professional use only. Applicators and workers must be trained, experienced, capable and equipped to mix, stir and apply the coating correctly in accordance with JOTUN's technical documents. Applicators and workers must wear appropriate personal protective equipment when using this product. This guidance is provided based on current product knowledge. Any proposed modification to suit site conditions must be approved by the responsible JOTUN representative before use.
Read the safety warnings on the container packaging. Use in well-ventilated conditions. Avoid inhaling spray mist and avoid skin contact. In case of accidental splashes on skin, wash immediately with a suitable cleaner, soap and water. In case of eye contact, rinse thoroughly with water and seek medical attention immediately.
When used primarily as a primer or antifouling coating, products may show slight colour variation from batch to batch. Such products, and epoxy products used as topcoats, may chalk when exposed to sunlight.
Gloss and colour retention of topcoats depend on the colour type, the surrounding environment such as temperature and UV intensity, application quality and product type. Contact your local JOTUN office for further information.
