This product may be applied by the following methods
| Spray: | Use specific conventional spray or HVLP (high-volume low-pressure) spray. Airless spray is not recommended. |
| Brush: | Recommended for touch-up and small-area application. Take care to achieve the specified dry film thickness. |

For the maximum recoat interval, refer to the Application Guide (AG) for this product.
Drying and curing times are determined based on temperature and relative humidity below 60%, with dry film thickness within the average range.
High-temperature and low-humidity environments are favourable for water vapour to evaporate from the film.
| Touch Dry | The state at which light finger pressure leaves no mark or stickiness. |
|---|---|
| Walk-on Dry | The minimum time after which the coating allows normal foot traffic without leaving permanent footprints, marks or other physical damage. |
| Handle dry | The minimum time after application before handling will not damage the film. |
| Paint temperature | 23 °C |
| Pot Life | 6 h |
Temperature
| Continuous | Peak | |
| Drying, atmospheric | 400°C | 540 °C |
The product can also withstand peak temperatures of 540 °C (1000 °F) for extended periods. However, sustained temperatures above 400 °C affect the long-term service performance of the inorganic zinc silicate coating.
Withstands peak temperatures for a maximum of one hour.
At the above temperatures, protective performance is unaffected, but appearance may be affected.

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.
The information in this datasheet is based entirely on knowledge gained in our laboratory and in practice. JOTUN products are regarded as semi-finished products, and their use is generally beyond our control. JOTUN therefore guarantees only the quality of the product itself.
