6 Best Anti-Slip Backing Sprays For Throw Blankets
Stop your throw blankets from sliding with our top 6 anti-slip backing sprays. Read our expert guide now to find the best product for a secure, non-slip grip.
Throw blankets often suffer from the “slide-off-the-couch” syndrome, especially when crafted from silky, low-friction fibers like alpaca or cotton. While the drape of a hand-knitted piece is lovely, its tendency to migrate onto the floor can be frustrating for the owner. Applying a specialized anti-slip backing is the practical solution for ensuring those hours of stitching result in a functional piece of home decor. This guide explores the best sprays available to help stabilize your work without compromising the integrity of your stitches.
Fiber-Lok Non-Skid Backing: Best for Hand-Knits
Fiber-Lok is widely considered the gold standard for textile artists because it is designed specifically for fabric and yarn. Unlike industrial-grade rubber sprays, it retains a level of flexibility that moves with the natural elasticity of knitted stitches.
It is particularly effective for blankets made with heavier weight yarns, like wool or acrylic blends. The application results in a soft, non-tacky finish that prevents sliding on leather or microfiber sofas.
Because it is water-based, it is often more forgiving than solvent-heavy alternatives. The takeaway is that for heirloom projects, this product offers the best balance of longevity and material safety.
Plasti Dip Multi-Purpose Spray: Most Versatile
Plasti Dip is a rubberized coating that provides a high-friction surface, making it an excellent choice for heavy-use blankets. If the goal is to create a grip that feels almost like a shelf liner, this is the most effective route.
The primary tradeoff is the texture, which can feel somewhat thick or “rubbery” compared to finer sprays. It creates a pronounced barrier that essentially seals the back of the knitted fabric.
This is a smart choice for pet owners or households with energetic children. It is durable enough to withstand significant friction, ensuring the blanket stays exactly where it is placed.
Rust-Oleum AntiSkid Spray: Heavy-Duty Option
This is a serious product intended for surfaces that need substantial traction. While it is often marketed for stairs or floors, it serves well on the backing of a chunky, thick-gauge afghan that sees heavy traffic.
One potential drawback is that it can feel gritty or textured to the touch. It is best used for decorative throws that will not be pressed directly against bare skin for long periods.
Given its heavy-duty nature, the application requires precision to ensure the blanket remains breathable. If the fabric is dense, this spray might add unwanted weight to the finished piece.
Sprayway SW077 Anti-Skid: The Best Clear Finish
For knitters concerned about aesthetics, the Sprayway SW077 provides a nearly invisible finish. It bonds well to synthetic fibers without leaving a yellow tint or a visible residue.
This spray is ideal for lightweight throws or delicate decorative pieces. It dries quickly, allowing for a faster turnaround time between application and final assembly.
The finish is less “sticky” than rubberized options, offering a subtle resistance rather than a hard stop. It is the best option for those who want the blanket to stay put without making the back of the work look heavily altered.
Krylon Non-Skid Coating: Easiest to Apply Evenly
Krylon is praised for its consistent aerosol nozzle, which helps avoid the clumping or uneven patches often associated with DIY spray applications. An even coat is vital for a consistent grip across the entire surface of the blanket.
The formulation is designed to be translucent and relatively thin. This helps maintain the drape of the blanket, ensuring it does not become stiff or board-like after the spray cures.
It is a reliable choice for beginners who are nervous about potentially ruining a finished project. The ease of application significantly lowers the risk of creating a messy, uneven texture on the back of the yarn.
Aleene’s Stop Fraying: Top Pick for DIY Dots
Instead of coating the entire back of the blanket, many knitters prefer applying small, tactical dots of grip. Aleene’s is perfect for this “spot application” method, allowing for precise placement.
By applying dots, you maintain the breathability of the fibers while still preventing the blanket from sliding. This is a much safer approach for sensitive natural fibers that might be damaged by a full-surface coating.
This method also saves product, as you only need a fraction of what a full-coverage spray requires. The result is a professional-looking, non-slip finish that feels intentional and well-designed.
How to Choose Your Anti-Slip Backing Spray
Selecting the right spray depends heavily on the fiber content of your blanket. Natural fibers like wool are more absorbent and may require a light, repeated application, whereas smooth synthetics might need a more aggressive, rubber-based coating.
Consider the intended use of the blanket before purchasing. A couch throw requires a different level of grip than a blanket used for a baby, where you must ensure the product is fully cured and non-toxic.
- For delicate natural fibers: Choose water-based, non-yellowing options.
- For high-traffic synthetic blankets: Opt for rubberized, heavy-duty sprays.
- For aesthetic preservation: Use clear-coat, thin-application formulas.
Applying Spray: A Step-by-Step Guide for Knits
Proper preparation is the most critical stage of the process. Always block your blanket to its final dimensions first, as applying spray to a piece that has not been fully shaped can result in a distorted finish.
- Lay the blanket flat on a protected, well-ventilated surface.
- Use masking tape to create a clean border if you want to avoid spraying the edges of the blanket.
- Hold the canister 10 to 12 inches away from the fabric, moving in a steady, side-to-side motion.
- Allow the first light coat to dry for at least an hour before assessing if a second coat is necessary.
Washing a Treated Blanket: Essential Care Tips
Treated blankets generally require gentler care than standard knitwear. Always opt for a cold, delicate machine cycle or hand wash to prevent the anti-slip coating from breaking down prematurely.
Avoid using high heat in the dryer at all costs, as heat can soften or melt the adhesive polymers. Instead, lay the blanket flat to air dry, which helps preserve the integrity of the grip dots or the spray coating.
If the grip begins to lose its effectiveness, avoid the temptation to re-spray immediately. First, ensure the blanket is clean, as dust and lint buildup often mask the “tack” of the coating, making it seem less effective than it actually is.
Is Anti-Slip Spray Safe for Your Blanket Fibers?
Most anti-slip sprays are chemically inert once fully cured, but they can still affect the “hand” or feel of the fiber. Natural fibers like alpaca or cashmere are particularly susceptible to losing their characteristic softness if coated too heavily.
Always perform a patch test on a small, hidden corner of the blanket—or better yet, on a test swatch made from the same yarn. If the yarn stiffens significantly or becomes discolored, opt for a different application method.
Avoid using these products on luxury silk blends or fibers that have not been treated for colorfastness. The chemical bonding process can sometimes interact with dye, potentially causing migration or spotting on lighter-colored yarn.
Choosing the right anti-slip treatment is a balancing act between functionality and maintaining the beautiful, soft hand of your hard-won knitting project. By selecting a product that suits your fiber content and applying it with patience, you can ensure your blankets remain both stylish and stationary. Always prioritize testing on swatches, and your finished items will provide years of cozy, reliable comfort.
