Questions & Answers
Is this a genuine International Paint product?
Yes, this is a genuine International (AkzoNobel) product supplied in original 2.5L trade/retail packaging.
Can I use this on a hull below the waterline?
No, One UP is strictly designed for use above the waterline (hulls, decks, superstructures). For below-waterline priming, we recommend International Primocon.
Do I need to sand between coats of One UP?
Sanding between coats of One UP is not required if overcoated within the specified window. However, the final coat of One UP should be sanded with 400-grade paper before applying your topcoat for the best finish.
