Hull Sanding
In this article we explain why hull sanding is necessary, which grit sequence to use, correct methods for different hull materials and how to protect DFT.
1. Why Is Hull Sanding Necessary?
Hull sanding is the mechanical keying process applied to the surface before any paint, primer or coating application. Paint cannot adhere to a smooth surface — sanding creates the micro-texture for mechanical bonding. Without it or done incorrectly, even the best paint begins to peel quickly.

2. Grit Sequence
40–60 (stripping) → 80–120 (standard surface prep for primer/AF) → 180–220 (fine prep before topcoat) → 320–400 (between topcoat layers) → 600–2000 (wet sanding before polish).
3. Conclusion
Hull sanding is the fundamental step of every successful marine painting project. DR.YACHT performs all sanding with DFT monitoring, correct grit sequence and material-appropriate techniques.
