How to Use Edge Kote: A Complete Guide to Professional Leather Edge Finishing

What is Edge Kote?

Edge kote is an acrylic-based edge finish I reach for when I want a fully sealed, coloured edge rather than a natural burnish. It seals, protects, and neatens the raw edge of a piece, and it's especially useful on projects where the leather itself won't burnish well on its own.

Why Use Edge Kote?

A raw leather edge can look unfinished and wears more over time. Edge kote earns its place on my bench for a few reasons:

• A proper finish: it gives a smooth, glossy edge that lifts the whole piece
• Protection: it seals the edge against moisture, dirt, and fraying
• Durability: it helps the edge stand up to daily wear
• Colour matching: it comes in a range of colours to suit the leather

Materials You'll Need

• Edge kote in your chosen colour
• Edge beveller
• Sandpaper (400-600 grit)
• Canvas cloth or wool dauber for application
• Burnishing tool (wood slicker or bone folder)
• Clean cloth

Step-by-Step Guide to Applying Edge Kote

Step 1: Prepare Your Edges

Preparation matters more than the product itself. I use an edge beveller to take the sharp corners off both sides of the leather edge first - it leaves a slightly rounded profile that takes the finish better and looks more considered.

Step 2: Sand the Edges

Using 400-600 grit sandpaper, smooth the edges thoroughly, sanding in one direction along the length of the edge to remove roughness or loose fibres. Wipe away the dust with a clean cloth. The smoother the edge before you apply anything, the better the final result.

Step 3: Apply the First Coat

Shake the bottle well before use. Using an edge dye pen applicator, roll a thin, even coat along the edge in smooth, continuous strokes to avoid streaks or buildup. Less is more here - thin coats dry cleaner and look far more professional than one thick pass.

Step 4: Let It Dry

Let the first coat dry fully - usually 15-30 minutes depending on humidity and temperature. It should feel dry to the touch before you move on.

Step 5: Sand Between Coats

Once dry, lightly sand the edge with 600-grit sandpaper to smooth out any imperfections, then wipe clean with a cloth.

Step 6: Apply Additional Coats

Apply 2-3 more thin coats, letting each one dry and sanding lightly between them. Several thin coats always give a more durable, better-looking finish than one thick one.

Step 7: Final Burnishing (Optional)

Once the final coat has dried completely, you can burnish the edge with a wood slicker or bone folder. Apply light pressure and work quickly along the edge for an even glossier finish.

Top Tips for Perfect Results

Temperature matters: apply edge kote at room temperature for the best result

Thin coats win: always go with several thin coats rather than one thick one

Clean your tools: wipe the applicator often to stop buildup and keep the application smooth

Practice first: test on scrap leather before touching a finished project

Store it properly: keep edge kote sealed and stored upright so it doesn't dry out

Common Mistakes to Avoid

i) Loading on too much product at once, which causes drips and uneven drying
ii) Skipping the edge prep - I've paid for this shortcut before
iii) Not giving each coat proper drying time
iv) Using edge kote that's gone old and thick and won't apply smoothly

Alternative Edge Finishing Methods

Edge kote suits plenty of projects, but it isn't the only option. Other edge finishing methods I use depending on the piece:

Burnishing: using water or gum tragacanth to polish the natural edge

Edge paint: similar to edge kote but a different formulation

Wax: the traditional route, using beeswax for a natural finish

Final Thoughts

Getting comfortable with edge kote takes a bit of practice, but the result is worth the effort. It's a finishing technique that can turn a decent piece into one that actually looks like it was made with care. Take your time with the prep and the thin coats, and you'll end up with edges that hold up as well as they look.
