Boat Non-Skid Deck Paint

What is the difference between single-part and two-part non-skid boat paint?

The primary difference between single-part and two-part non-skid marine paint is durability and cure chemistry. Single-part paints dry via solvent evaporation, while two-part coatings cure through a chemical reaction.

• Single-Part Polyurethane (e.g., Interlux Interdeck, Pettit EZ-Decks): Best for DIY users. Highly flexible and simple to touch up, but requires reapplication every few seasons.
• Two-Part Polyurethane/Epoxy (e.g., Awlgrip Griptex): Best for professional or high-traffic commercial decks. Offers maximum chemical and abrasion resistance, but requires precise mixing.
• Water-Based Coatings (e.g., KiwiGrip): An eco-friendly, low-odor option that allows you to easily customize texture aggressiveness using specialized rollers.

How do you apply non-skid texture to a boat deck?

You can add non-skid texture to a boat deck using three primary methods: pre-mixed paints, the broadcast method, or the stir-in method. The right choice depends on your desired texture aggressiveness.

1. Pre-Mixed Coatings: Ready-to-use paints like Interlux Interdeck contain compound particles suspended in the formula. Apply using a specialized textured foam roller to ensure even particle distribution.
2. The Broadcast (Salt Shaker) Method: Apply a base coat of standard marine paint, then manually shake loose particles like Awlgrip Griptex Non-Skid Additive onto the wet paint. Vacuum the excess once dry, and apply a final locking topcoat.
3. The Stir-In Method: Mix non-skid particles directly into your paint can prior to rolling. Continuously stir the mixture during application to prevent the grit from settling to the bottom.

Can you apply non-skid paint over existing gelcoat?

Yes, you can apply non-skid paint over existing molded gelcoat, provided the surface is completely de-waxed and mechanically abraded to ensure mechanical adhesion.
