International One UP Primer/Undercoat

Description

International One UP Primer & Undercoat is a versatile single-pack primer and undercoat designed for use above the waterline with International one-pack topcoats and deck paints. It replaces traditional yacht primer and pre-kote systems, offering excellent adhesion and a smooth, easy-to-prepare surface for finishing coats.

Suitable for a wide range of substrates including fibreglass, wood, aluminium, lead, cast iron and steel, One UP is easy to apply by brush or roller and sands smoothly between coats. Its formulation helps reduce the overall preparation time and improves the appearance of the topcoat once applied.

This primer is ideal for owners undertaking topside painting projects with one-pack finishes and for ensuring a well-prepared base that enhances overall coating performance.
