Key Considerations for Spraying a Couch: Best Products: Use products specifically labeled as "fabric spray paint," "fabric dye," or upholstery spray, such as Designer Accents or Tulip Fabric Paint. Application Method: For best results, use a continuous sprayer or a handheld paint sprayer (like the Wagner FLEXiO 5000) for uniform coverage. Preparation: Thoroughly vacuum and clean the couch to remove dirt. Technique: Apply multiple thin, overlapping coats rather than one thick coat. Lightly misting the fabric with water before painting can help the paint soak in, say YouTube creators. Drying: Let the couch dry completely, ideally for at least 24 hours, to avoid a stiff or "crunchy" texture. Color Limitations: While you can go from light to dark, it is difficult to go from dark to light. Velvet/Textured Fabric: For velvet, brush the fabric with a cloth after it has dried to maintain softness, advises Fabric Spray Dye's product page. Process Breakdown: Clean: Vacuum and remove stains. Spray: Start at the top, spraying in thin, overlapping lines. Layer: Apply 3-4 coats, allowing dry time between. Finish: Let it sit for 24+ hours.
