Hempel’s Multicoat Light Blue – Antifouling Primer & Tie Coat (750 ml)

Prepare your boat’s underwater hull for outstanding antifouling performance with Hempel’s Multicoat — a trusted primer and tie-coat designed to maximise adhesion and improve the lifespan of your antifouling paint system. This 750 ml tin in light blue is perfect for small boats, yachts and vessels where precision coating and paint adhesion are key.

🛥 What Is Hempel’s Multicoat?

Hempel’s Multicoat serves as a primer and tie coat between the hull substrate and your antifouling paint. It enhances adhesion and promotes smooth, even coverage for subsequent antifouling layers — a critical step for professional, lasting hull protection.

Hempel’s Multicoat is compatible with a wide range of antifouling paints and is especially useful:

• on bare GRP (fibreglass)

• on existing antifoul that needs keying

• when transitioning between different antifouling types

• to improve overall coating performance

⭐ Key Benefits

• 🎨 Excellent adhesion: Improves bond between hull and antifouling paint

• 🛠 Tie coat performance: Helps new antifouling adhere even over aged coatings

• 💧 Smooth finish: Promotes even topcoat application with fewer imperfections

• 🧽 Easy to apply: Brush, roller or pad application depending on surface

• 📏 Perfect for small vessels: 750 ml size ideal for DIY and maintenance projects

🧰 When to Use Multicoat

Use this multicoat primer:

Proper use of a tie coat like Multicoat increases durability and can reduce premature peeling or flaking of the antifouling layer — helping you get the most out of marine coatings.
