International One Up Primer Undercoat is a new two-in-one primer and undercoat for use above the waterline with traditional single pack topcoat paints such as International Toplac Plus and International Interdeck.
International One Up is a simple, yet effective primer and undercoat in one tin, making painting easier for DIY customers, without compromising on aesthetic appearance or substrate protection. It is extremely easy to apply with a brush or roller leaving an extra smooth finish.
Thinning of One Up Primer Undercoat is not usually required, however, it can be thinned up to 10% if required using Thinners No.1.
One Up primer and undercoat is suitable for use on most materials, such as fibreglass & GRP, gelcoat and wood.
It is recommended to use at least 2 coats of International One Up before applying the topcoat. For GRP/Gelcoat 2 coats should be enough, for aluminium and steel 3 coats are recommended and for wood, at least 4 coats are recommended.
