Prepare your boat for a flawless finish with Hempel’s Primer Undercoat — a high-opacity, quick-drying primer and undercoat in a convenient 750 ml tin. Designed for use above the waterline on boats and yachts, it gives excellent surface stability and durability before applying topcoats like Hempel Brilliant Gloss or MultiCoat.

Key Features

• 🛥️ Dual-Purpose Primer & Undercoat: Acts as a primer on bare substrates and an undercoat beneath single-component topcoats.

• 👌 High Opacity & Coverage: Excellent hiding power in mid grey, ideal for colour changes and prepping surfaces.

• 🎨 Marine Use: Use before topcoats like Brilliant Gloss, MultiCoat or non-slip deck coatings.

Why Use a Primer Undercoat?

Primer undercoats improve the adhesion and longevity of your topcoat paint system. They help to create a smooth, stable surface, reduce the number of topcoat layers needed, and enhance overall finish performance.
