Heavy Duty Fabric Wax | Regular Bar
Otter Wax Heavy Duty Fabric Wax is the bar that started it all - our first product, our flagship, and where we got the name Otter Wax. Handmade in Portland, Oregon, this fabric wax is made with premium filtered beeswax and our proprietary blend of plant-based waxes and oils to help canvas, waxed canvas, and oilcloth, jackets, bags, gloves, tents, and other outdoor gear repel water, resist abrasion, and hold up to years of use. It bonds directly to fabric fibers for long-lasting protection and a classic waxed finish, without relying on paraffin, silicone, petroleum solvents, or PFAS chemicals.

THE ORIGINAL
HEAVY-DUTY FABRIC WAX
LONG-LASTING WATER REPELLENCY
Otter Wax Heavy-Duty Fabric Wax Bar adds durable water resistance to canvas by building up a protective wax finish. Apply the bar directly with friction, then work the wax into the fabric for a classic waxed look that helps protect against moisture and wear.
Perfect for the hard-working canvas in your life: jackets, bags, work gloves, aprons, hats, tool rolls, tarps, totes, canvas rifle cases, and DIY projects. It’s especially useful for projects that need added water resistance, durability, and abrasion resistance whether on the hiking trail or in the workshop.
Use it on heavy, natural-fiber fabrics like canvas, cotton, waxed cotton, denim, duck cloth, and oilcloth. It also works on cotton-blend fabrics with a higher cotton content, but for best results, skip 100% synthetic materials like nylon or polyester. Still have questions?

BEFORE
AFTER
Remember to always test Otter Wax Heavy-Duty Fabric Wax on a small, discreet spot prior to waxing your entire item in order to ensure that desired results will be achieved. Always allow your newly waxed item to cure in a warm, dry place for 48–72 hours to fully set and maximize waterproofing and durability.
FAQ
It totally depends on what your project is. As a general rule of thumb, 1 of our Regular Bars is enough to wax 2 baseball hats. Waxing a raincoat? You'll want to get yourself at least 2 Large Bars. Materials can vary widely, so be sure to check out our comprehensive Wax Coverage Guide
How often you reapply Otter Wax depends on use and exposure. Most customers reapply when they notice water no longer beading up and soaking into the fabric. As a general rule of thumb we recommend rewaxing your item at least once a year and light touchups whenever necessary.

You can certainly apply either our Fabric Dressing or Wax Bars to nylon, polyester, or polyblend fabrics, but keep in mind they work best on natural fibers (cotton, hemp, jute). With synthetics you’ll often see pilling or flaking as the wax doesn’t really “soak in” and less durable water resistance, especially in high-flex areas.
We recommend letting freshly waxed items cure for 24 to 72 hours in a warm, dry place before putting them to use. Cooler temps, high humidity, or heavier applications of wax can all extend the curing time. You’ll know it’s ready when the surface no longer feels tacky.
For best results, start with a light coat—you can always add more later. Taking the time to let the wax fully set will ensure a smooth, long-lasting finish.
