Awlgrip Primers & Undercoaters

Awlgrip Primers & Undercoaters: The Foundation of a Flawless Marine Finish

When a world-class topcoat finish is the goal, the primer system underneath is just as critical as the paint on top. Awlgrip has understood this from the very beginning, building a range of primers and undercoaters engineered specifically to work in harmony with their legendary topside coatings. Whether you're preparing a fiberglass hull, a metal deck, or bare substrate above or below the waterline, Awlgrip's primer lineup offers a purpose-built solution for every stage of the paint system.

A Primer System Built for the Marine Environment

Awlgrip primers are two-component epoxy formulations designed to deliver outstanding adhesion and corrosion protection across a wide variety of marine substrates. The flagship of the lineup, the 545 Epoxy Primer, is a dual-purpose workhorse: it seals both undercoats and surfacing primers before topcoat application and is engineered for use both above and below the waterline. Its outstanding corrosion resistance helps increase the longevity of the entire coating system, making it a staple on production yachts and professional refit jobs alike.

For applications where filling and leveling are the priority, the Ultra Build / High Build Epoxy Primer delivers a thicker, filling-grade build designed for above-waterline use. This two-component surfacer is ideal where print-through resistance and a smooth, fair base are essential before applying premium topcoats like Awlgrip HDT or Awlcraft 2000.

Rounding out the lineup is Awlquik, a quick-drying, medium-build, easily sanded two-component epoxy primer/surfacer — a go-to choice when work cycles need to move fast without sacrificing surface quality. Awlgrip also offers the 321 HS Undercoat, a low-VOC, globally compliant undercoater engineered for excellent sandability and a one-coat application that reduces labor time while delivering an ideal base for Awlgrip and Awlcraft topcoats.

Why Awlgrip Primers Stand Apart

Awlgrip is part of the AkzoNobel family of coatings brands, and that research-and-development depth shows in their primer chemistry. These products are formulated to integrate seamlessly with the rest of the Awlgrip system — from fairing compounds through to final topcoats — ensuring adhesion, compatibility, and long-term durability are never left to chance. Professional yards, boat builders, and serious DIY enthusiasts trust Awlgrip primers precisely because they are developed as one piece of a complete, engineered coating system, not standalone products.

For anyone planning a repaint, a new build, or a full restoration, starting with the right Awlgrip primer is the single most important step toward achieving that unmistakable, mirror-like Awlgrip finish.
