What buyers ask about Sunbrella fabric—and what I wish I'd known sooner
I've been handling Sunbrella orders for awning and marine clients since 2019. In that time, I've made some expensive assumptions. The classic one: thinking all outdoor fabrics are basically the same, so just pick a color and go.
Wrong approach. That cost me a $3,200 redo on a boat order the first year.
So here's the short version of what I've learned, structured around the questions I get most often. If you're a manufacturer or wholesaler specifying Sunbrella for the first time—or even the tenth—these are the things that actually matter.
1. What exactly is Sunbrella fabric?
Sunbrella is a solution-dyed acrylic performance fabric. The key part is "solution-dyed": the color pigment is mixed into the liquid acrylic before it's extruded into fibers. That means the color runs through the entire fiber, not just the surface.
Why that matters for marine and awning applications: dye fades, but pigment embedded in the fiber doesn't. At least, not the same way. A solution-dyed acrylic like Sunbrella will hold its color years longer than a solution-dyed polyester or a printed fabric.
I've seen awnings with 8 years of direct sun exposure that still looked presentable. You won't get that with cotton canvas or standard polyester.
2. Is Sunbrella truly waterproof?
No—and I wish more sales guys were upfront about this.
Sunbrella is water-resistant, not waterproof. It repels water initially because of a water-repellent finish applied during manufacturing. But under sustained pressure—like a rain puddle pooling on a boat cover—water will eventually seep through.
If you need a truly waterproof top for a boat or a shade structure, you'll need a laminated or coated backing, or you'll need to apply a separate waterproofing treatment (like Sunbrella Restore) periodically. Running the numbers in 2024, I estimate 30% of the warranty issues I've seen trace back to this specific misunderstanding.
Tip for specifiers: always clarify the end-use pressure. A bimini top that sheds light rain is different from a cover that holds standing water.
3. What's the proper way to clean Sunbrella canvas?
Mild soap and water. That's it. Really.
Bleach? Only if you're careful and it's diluted. Standard bleach can degrade the acrylic over time. I've seen cleanings that looked great for two weeks, then the fabric started to feel brittle. (Note to self: document that comparison test from September 2023.)
Here's a routine that works:
- Routine cleaning: Hose off dirt, then scrub with a soft brush and a solution of mild soap (like Woolite or Dawn) in lukewarm water. Rinse thoroughly.
- Mildew spots: Mix 1 cup of bleach (or hydrogen peroxide for a gentler option) with 1/4 cup of mild soap per gallon of water. Apply, let sit for 15 minutes, scrub, rinse. Test a hidden area first.
- Stubborn stains: Sunbrella has a cleaning guide on their site, but honestly, most stains come out with patience. Not always instant results. I had a grease stain on a patio cushion that took three rounds over two weeks before it faded to acceptable.
4. Can Sunbrella be restored if it loses water repellency?
Yes. Sunbrella Restore™ Fabric Protector & Repellent exists for this.
Over time (anywhere from 1 to 3 years depending on UV exposure and cleaning frequency), the factory-applied water repellent wears off. The fabric still looks fine, but water no longer beads up. That's when you apply Restore.
I've used it on a 40-foot boat enclosure. Application took about an hour for two people. Result: water beading returned to factory spec. The product is straightforward—spray on, let dry. Costs about $20–30 per can, and one can covers roughly 100 square feet.
One thing I didn't realize: you need to clean the fabric thoroughly before applying Restore. Dirt blocks the repellent from bonding. Learned that the hard way when a patch of my first application peeled off after a rainstorm.
5. What colors are available? (And how does Capri fit in?)
Sunbrella's color catalog runs over 100 shades. The Sunbrella Canvas Capri is one of the heavier canvas-weight fabrics. It's intended for applications where you need more structure—like bags, outdoor furniture upholstery, or heavy-duty awnings.
Capri is a colorway, not the fabric type. Sunbrella Canvas is a product line, and Capri is one of its color options (a medium blue, similar to a faded denim tone). If you're sourcing Capri, make sure you're talking about the right product: Sunbrella Canvas in the color Capri, not just "Capri fabric."
I've had three separate ordering mistakes where the customer meant Capri as a color and the supplier thought they meant a different product line. Always confirm both the product name and the color name on the spec sheet.
6. Do I need special thread or zippers for Sunbrella?
Yes, and this is a common blind spot.
Standard polyester thread will degrade faster than the fabric. For Sunbrella, use UV-resistant polyester thread or bonded nylon. Same with zippers: outdoor-grade, non-corrosive zippers (preferably brass or stainless steel). Plastic zippers won't hold up to the UV or the physical stress from repeated use on a boat or awning.
I had a project in 2022 where we used standard YKK zippers on a sailboat cushion set. They seized up within 6 months due to salt spray. Replacement cost: $450 and a lot of angry emails. The marine-grade zippers added about $12 per cushion initially. Worth it.
7. Can I use Sunbrella for applications like crochet patterns or clothing?
Not really, and people ask this more than you'd think.
Sunbrella is an industrial-grade woven fabric. It's heavy, stiff compared to apparel fabrics, and not suitable for crochet (it doesn't have the drape or stretch) or for a standard denim button-up shirt. If someone searches for a "crochet hand towel pattern" or a "denim button up shirt" and lands on a Sunbrella page, they'll be disappointed.
But here's a connection that does make sense: if you're looking for a durable, UV-resistant fabric for outdoor cushions that might get used like a beach towel, then yes. But that's a different use case from a crochet pattern.
8. What about Kevlar? Is Sunbrella related?
No. Kevlar is a completely different material—an aramid fiber used for bulletproof vests, gloves, and industrial applications where cut resistance is needed. Sunbrella is acrylic. Not related. If you need Kevlar, you're not looking for Sunbrella.
I've had a client once ask if Sunbrella could replace Kevlar for a marine safety harness. Short answer: no. Two different worlds. If your Google search brought you here because you typed "what are Kevlar" and the SEO keywords overlapped, I'm sorry for the confusion. But now you know.
Final thought: Sunbrella is a great fabric—for specific things. The question isn't "can it do everything?" It's "is this the right choice for your specific marine, awning, or outdoor furniture application?" If you want to avoid some mistakes I made, ask the questions above before you place the order.
