International ONE UP

**One-component primer/undercoat for above-waterline surfaces** One UP is a one-component primer/undercoat designed for use above the waterline in combination with International's one-component topcoats and deck paints. Simple yet effective – it makes painting easy even for DIY boat owners, without compromising the appearance or protection of the substrate. International One UP is a primer and undercoat in one product, designed to prepare above-waterline surfaces of boats for one-component topcoats. It creates an exceptionally smooth base that sands easily, so the topcoat achieves a finer, more even finish. It is suitable for steel, aluminium, galvanised steel, polyester (GRP), epoxy and wood – on superstructures, cockpits, cabins, decks and other surfaces above the waterline. Being easy to use, it suits both professionals and boat owners who carry out their own maintenance. **Key features** - One-component primer and undercoat in one - For use above the waterline only - Exceptionally smooth base, easy sanding - For steel, aluminium, galvanised steel, GRP, epoxy and wood - Compatible with International one-component products: Toplac, Toplac Plus, Super Gloss HS, Interdeck, Danboline, Bilgekote and Watertite - Easy application by brush or roller - Colours: white and blue-grey **Recommended number of coats** - GRP: 2 coats - Steel and aluminium: 3 coats - Wood: 4 coats **Technical data** - Coverage: approx. 9 m²/L per coat - Minimum temperature (product, air and substrate): 5 °C - Thinner: International Thinner No. 1 or Thinner No. 100 (up to 10 % if required) **Important:** One UP must not be overcoated with two-component (2K) solvent-based products – it is compatible only with one-component topcoats and deck paints. **Note:** Always consult the latest manufacturer's Technical Data Sheet (TDS) and Safety Data Sheet (SDS) before use for detailed instructions on application, dilution and substrate compatibility.
