Weatherproofing outdoor cushions involves protecting both the fabric from moisture and stains, and the internal foam from absorbing water.
Weatherproof outdoor cushions by cleaning them, then applying a water-repellent spray like Scotchgard Sun & Water Shield or 303 Fabric Guard annually to repel water and prevent UV fading. For maximum protection, use waterproof covers or wrap foam inserts in plastic to prevent moisture from reaching the inner core.
Waterproofing outdoor cushions involves cleaning the fabric, applying a water-repellent spray, and protecting the inner foam. Reapply the protective spray annually and store the cushions during severe weather to prevent mildew and extend their lifespan.
Just because something belongs outside doesn't mean it can't look brand-new. When it comes to outdoor furniture and gear, Scotchgard™ Protectors keep the water off and the fun turned on. Creates a barrier to water that keeps fabric dry longer. Helps keep rain and snow off furniture and fabric.
You can leave standard outdoor cushions in a light rain, but it is not recommended for heavy downpours. While water-resistant fabrics shed some moisture, standard foam acts like a sponge. Leaving them soaked can cause mold, mildew, and permanent damage.
Patio furniture made from rust-proof metals, dense tropical hardwoods, and synthetic plastics can safely withstand the rain. Ideal weather-resistant options include powder-coated aluminum, teak wood, high-density polyethylene (HDPE) lumber, and all-weather wicker. Standard cushions should always be stored to prevent mold and mildew.
Always cover your outdoor furniture or store it indoors over winter. Leaving pieces unprotected exposes them to harsh moisture, freezing, and wind damage—which can lead to rust on metal, cracks in wood or wicker, and devastating mold growth on your cushions.
Safer alternatives to traditional Scotchgard rely on eco-friendly, non-toxic ingredients like silicon dioxide (silica) or silicone, effectively repelling liquids and stains without relying on harsh PFAS or fluorocarbon chemistry.
3M phased out the original formula of Scotchgard in 2000 because its active ingredient—a PFAS "forever chemical" called perfluorooctane sulfonate (PFOS)—was found to be accumulating in the environment and in human blood.
The absolute best waterproof materials for outdoor cushions are marine-grade vinyl or solution-dyed acrylic (like Sunbrella) treated with a waterproof backing. The ideal choice depends on your climate and how you prioritize comfort versus extreme weather protection.
Method 2: Waterproofing Spray
This method works best for items that can't be washed such as upholstery, outdoor cushions, and tightly woven natural, twill, or cotton fabrics. I recommend this Fabric Guard repellant product because it works well.
To use Dawn when cleaning outdoor furniture, use a mixture of: 1/4 cup of Dawn dish soap. 1 gallon of warm water. Scrub with a rag or soft brush, paying attention to areas with mildew buildup.
The absolute best way to waterproof outdoor cushions is to combine a quality spray-on fabric protector with physical moisture barriers. Thoroughly clean the cushions, apply a specialized water-repellent spray, and if your inserts aren't waterproof, wrap the foam in heavy-duty plastic to keep it dry.
"When they're exposed to cold, damp conditions, they can become a breeding ground for mold and mildew." This is something Rowell agrees with. Both experts suggest storing your outdoor furniture cushions inside or in a deck box until the following spring to keep them clean and dry.
Yes, certain Scotchgard formulas prevent fading by blocking harmful UVA and UVB rays from the sun. However, this protection depends entirely on using the right product.
Top alternatives to Scotchgard for fabric protection include TriNova Non-Aerosol Stain Guard (best for indoor use), 303 Marine Fabric Guard (high-performance water repellent), and ForceField (non-toxic and safe for all fabrics). These options offer effective, durable stain resistance while often providing more eco-friendly or non-toxic formulations.
The best all-around fabric protector for upholstery is Scotchgard Fabric Water Shield. It is the most effective and durable spray for repelling liquids and blocking stains without altering the natural look and feel of most indoor fabrics.
Do not use Scotchgard on leather, suede, imitation suede, silk, wool, velvet, polyethylene, finished wood, plastic, or "X" or "S" coded fabrics. Additionally, avoid spraying it over wet ink or pen autographs, as the liquid may cause the colors to bleed.
The best waterproofing spray depends on your fabric: use Scotchgard Fabric Water Shield for everyday clothes and upholstery, Nikwax TX.Direct for technical outdoor gear and rain jackets, and 303 Fabric Guard for heavy-duty marine canvas and patio furniture.
Yes, you can and should Scotchgard outdoor cushions! It creates a durable water barrier and protects fabric from UV fading and mildew without altering the texture or breathability.
Apply a fabric stain protector like Scotchgard or choose stain-proof upholstery fabric. Regular maintenance, such as vacuuming and prompt stain removal, also helps preserve the protective properties and extend the lifespan of the fabric.
Learn which items should never be kept outside during winter, and where to store them instead so that they'll be safe and ready for spring.
Garden furniture that can safely survive year-round outdoors is built from durable, weather-resistant materials like powder-coated aluminum, premium teak, polyethylene (PE) wicker, and certain plastics. While the frames can endure the elements, cushions and fabrics must always be stored indoors during wet or freezing weather.
Covering your patio furniture can help prevent damage from snow, rain, and wind during winter. It's important to use quality covers made with waterproof materials and zip or cinch closures.
