STARKE Sandpaper
The Abrasive Game Has Changed
Nobody in the marine industry has attacked sandpaper and abrasives the way STARKE has. While everyone else was selling the same tired sheets, STARKE went back to zero — engineering marine abrasives from the ground up for the demands of gelcoat, fiberglass, and high-end paint correction. The result: faster cut, dramatically longer life, and a finish that makes the work speak for itself.
Professional detailers and serious boat owners who've made the switch don't go back. Less loading. Less swapping. Less wasted time. STARKE outperforms every sheet you've used before — and it's not close.
This is what the abrasive game looks like when someone finally gets it right.
STARKE FORGE Premium Sandpaper
STARKE Forge — High-Output Sanding Disc
Engineered for Yacht & Marine Manufacturing
When the job demands maximum cut and consistent results across long sessions, Forge delivers. Built around STARKE's proprietary CoruEdge Technology, the Forge disc is engineered for professionals who can't afford downtime, inconsistency, or a disc that dies halfway through a panel.
CoruEdge Technology
At the core of every Forge disc is a precision blend of zirconia and aluminum oxide grains engineered to fracture in a controlled, predictable way as you work. Each fracture exposes a fresh cutting edge, so the disc keeps biting aggressively through the entire session — not just the first few passes. The result is fast, efficient material removal with a consistent scratch pattern that sets up clean, uniform finishing every time.
Anti-Load Surface Shield
Loaded discs slow you down and cost you money. Forge's Anti-Load Surface Shield is built to resist the clogging that kills lesser abrasives on gelcoat, filler, and primer. You stay in the cut longer, change discs less often, and maintain the scratch pattern your next stage depends on.
RigidCore Backing System
The RigidCore backing keeps the disc flat and stable under pressure, delivering consistent contact across the entire surface. No chatter. No uneven cut. Just controlled, repeatable performance whether you're working a flat panel or a compound curve.
Resin-over-Resin Bonding
Forge is built to handle the heat and pressure of aggressive dry sanding. Our heat-resistant resin-over-resin bond locks the grain in place under load, preventing premature grain loss and keeping the abrasive performing long after cheaper discs have given up.
Dry Performance
Forge is optimized for dry sanding applications — no water, no lubricant required. That means efficient, consistent material removal on gelcoat, fiberglass, metal, paint, and plastic without the added steps or mess of wet sanding prep.
Hook & Loop Attachment
Fast pad changes, secure hold. Forge mounts to any standard hook and loop backing pad and stays put through even aggressive sanding passes.

STARKE MORPH Sandpaper Disc
STARKE Morph — Adaptive Surface Abrasive
Soft Foam Interface Disc for Gelcoat, Marine Paint, and Clearcoat Refinement
Gelcoat and marine paint don't forgive sloppy finishing. The surface either comes out right or it doesn't — and the abrasive you use in the final steps before buffing determines which one it is. Morph was built for those steps.
A knitted fabric-on-foam disc engineered for high-end surface refinement on gelcoat, marine topcoats, and clearcoat, Morph delivers the controlled cut, consistent scratch pattern, and swirl-free finish that professional marine detailers and refinishers demand before the buffer ever touches the boat.
Built for Gelcoat and Marine Paint
Gelcoat is unforgiving. It's harder than automotive clearcoat, prone to haze from inconsistent abrasive contact, and there's limited material to work with before you're through to the substrate. Morph's even contact distribution and P-graded silicon carbide grain give you a predictable, uniform scratch pattern at every grit — the kind that buffs out cleanly without leaving sub-surface haze that comes back after polishing.
Marine paint and topcoats demand the same precision. Whether you're leveling orange peel on a freshly sprayed topside, refining wet sanding scratches before a final cut polish, or prepping a surface for ceramic coating, Morph gives you the control to do it right without burning through or leaving uneven marks.
Adaptive Flex Interface
Morph's flexible foam backing conforms to the compound curves, transitions, and hull geometry that make marine finishing different from flat-panel work. Consistent abrasive contact across a curved surface — no bridging, no edge bite, no high spots. The disc follows the hull, not just the flat sections of it.
Knitted Fabric-on-Foam Construction
The knitted fabric layer between the foam and abrasive distributes cutting pressure evenly across the full disc face, eliminating the hot spots and chatter that cause uneven haze on gelcoat. Smooth, even contact from edge to edge on every pass.
Silicon Carbide Abrasive
P-graded silicon carbide delivers fast, predictable cutting and a consistent scratch pattern across the life of the disc. Sharp, clean, and well-suited to wet sanding applications — silicon carbide performs especially well on hard surfaces like gelcoat where you need a controlled cut without excessive heat buildup.
Optimized for Wet Sanding
Morph is purpose-built for wet use — the preferred method for gelcoat and marine paint work. Water keeps the surface cool, extends disc life, and produces a smoother finish than dry sanding at equivalent grits. Less heat means less risk to sensitive marine finishes, longer sessions without performance drop, and less material consumed per repair.
Grip Attachment
Hook and loop mounting for fast pad changes on any standard grip sander.
Available Grits: P1000, P2000, P3000
Pack Size: 15 discs / box
Sizes: 6", 5", 3"
Attachment: Hook & Loop (Grip)
Best For:
Marine gelcoat refinement and repair, yacht topcoat and marine paint finishing, pre-polish and pre-coating surface prep, scratch removal and surface leveling, automotive clearcoat refinement, and any professional finishing environment where surface quality and consistency are non-negotiable.
Where the boat meets the buffer — Morph gets the surface ready.

STARKE RAZOR Mesh Sandpaper
STARKE Razor — Mesh Sandpaper Disc
Powered by CoruEdge Technology
Always Razor-Sharp. Cuts Faster. Lasts Longer.
The standard for marine surface finishing just changed. STARKE Razor Mesh Sanding Discs are built around CoruEdge Technology — a semi-brittle corundum grain system that continuously self-renews during use, fracturing in a controlled way to expose fresh, sharp cutting edges with every pass. The disc doesn't dull. It sharpens itself as it works.
The result is a sanding disc that cuts faster than traditional sandpaper, maintains a cleaner scratch pattern through the entire session, and lasts significantly longer — so you're changing discs less and finishing more.
CoruEdge Technology — Always Razor-Sharp
Traditional abrasive grains wear smooth and lose their edge. CoruEdge semi-brittle corundum grains are engineered to fracture in a controlled, predictable way during sanding, continuously revealing fresh cutting edges. The cut stays aggressive from the first pass to the last, delivering faster material removal, a more consistent scratch pattern, and longer overall disc life compared to conventional sandpaper.
Marine/Industrial-Grade Mesh Construction
Razor's open mesh substrate is purpose-built for dry sanding on boats, yachts, fiberglass, and marine substrates. The open weave keeps the cutting surface clear by channeling dust and debris away from the abrasive, resisting the clogging that kills disc performance and contaminates the surface. Maximum dust extraction means a cleaner workspace, healthier air, and a surface that's ready for the next stage without rework.
Built for Professional Results
Durable hook and loop backing mounts fast and holds firm to any standard backing pad, standing up to the sustained pressure of professional yacht refinish and surface preparation. Premium abrasive grains and consistent construction deliver the repeatable, reliable results that high-volume marine finishing demands.
