Fillers & Putties
Choose the right marine filler or putty for your application.
Marine putties and fillers are used under paint to create a smooth surface. One major difference between these products is whether they can be used below the waterline. Another difference is whether the marine filler or putty filler is one-part or two-part. One-part putty fillers tend to be less waterproof than two-part epoxy fillers or two-part polyester or polystyrene fillers. Examples of marine-grade putties and boat hull fillers include Travaco’s Marine-Tex® Epoxy Putty, Interlux’s Watertite Epoxy Filler and Pettit’s Splash Zone EZ-Fair Epoxy Fairing Compound. Custom, marine-grade fillers and fairing compounds can be created by mixing WEST SYSTEM Two-Part 105 Resin with a variety of thickeners and fillers.
