| Wet Film Thickness | 160-315 µm |
| Theoretical Spreading Rate | 6.4-3.2 m²/L |
| Practical consumption on concrete | 0.15-0.3 L/m². All vinyl ester and polyester coatings may shrink during curing. This causes the practical spreading rate to be lower than the theoretical spreading rate. The shrinkage depends on the actual dry film thickness and application conditions. |

The packaging sizes above are typical reference sizes for factory batch production. Due to regional regulatory differences, packaging sizes and capacities may vary by region.
Store in accordance with national regulations. Keep containers in a dry, cool, well-ventilated place away from heat and sources of ignition. Keep containers tightly closed. Handle with care.
Vinyl Ester High-Strength Acid-Resistant Sealer 4 months
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.
The information in this datasheet is based entirely on knowledge gained in our laboratory and in practice.
