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.
