Many customers know this as spray string. You’ll also see it described as party streamer spray, string in a can, or novelty string spray. All of these refer to colorful foam strands that spray from an aerosol can for quick party fun.

• Common uses: birthdays, graduations, holidays, photo ops.
• Typical options: assorted colors, single cans or bulk multipacks, 2.5–3 oz sizes.
• Good to know: formulas and cleanup guidance vary by item.

For the best experience, review the product description and label for surfaces, ventilation, and cleanup guidance before you spray.

You can shop spray string on Walmart.com and, where available, choose shipping, pickup, or delivery. Inventory varies by location and time.

• Browse this category to compare colors, pack sizes, and can sizes.
• Use filters to narrow by quantity or color for your theme.
• To check local stock, select your store or enter your ZIP code on the product page.

Spray string isn’t designed for automotive finishes, and using it on vehicles can carry risks. Some dyes or propellants may affect paint or clear coat, especially on warm surfaces or if left to dry.

• Avoid spraying on cars, motorcycles, and other finished surfaces.
• If contact happens, gently wipe off promptly with a soft cloth and mild soapy water; avoid abrasive pads or harsh solvents.
• Always test a small, inconspicuous spot before broader cleanup.
• Check the can’s label for surface guidance and warnings.

For the least hassle, use spray string outdoors away from vehicles and delicate finishes. Results can vary by formula and surface condition.

It can be used indoors with care, but a few precautions help. Aerosol products may be flammable and can leave residue on some surfaces.

• Keep away from open flames, heat sources, and pilot lights.
• Provide ventilation and avoid confined spaces.
• Protect delicate fabrics, porous materials, and decorative finishes; consider covering tables or floors.
• Spot test on an inconspicuous area and follow label directions for use and cleanup.
• Supervise kids and aim sprays away from faces and fixtures.

If you’re unsure about a surface, consider using spray string outdoors or on easy-to-clean areas to simplify cleanup.

It depends on can size, how enthusiastically guests spray, and how long you want the activity to last.

• As a rough planner, one 2.5–3 oz can per guest supports a short round of spraying.
• For brief finales or photo moments, one can for every 2–3 guests may be enough.
• Bulk multipacks are convenient for larger groups and color variety.
• Mix colors to match your theme, and keep a few extras for last‑minute needs.

These estimates are only guidelines. Actual coverage varies by formula and spraying style, so adjusting up or down based on your event is reasonable.
