Vinyl can initially seem hard to paint, but that is often because we treat vinyl like a wall. Acrylic paint cannot stick to plastics like vinyl unless they are appropriately primed with a primer that is made to adhere to plastics, which are widely available at national home improvement stores and even online. After the application of this material, painting a vinyl record is as easy as painting anything else in your home. Just put on a smock and get ready to paint.
Remove all dust and dirt from the records with a rag soaked in soapy hot water. Let the records dry or wipe them down with a separate clean rag.
Prime the records with a spray primer for plastics, such as Rustoleum's Plastic Primer Spray. Apply a single, thin coat, following the direction listed on your chosen product. Let the records dry for at least an hour, and apply a second coat.
Apply a spray paint made for plastics, such as Krylon's Fusion for Plastics Spray Paint. Apply in long, even strokes across the surface of the records. Let it dry for about an hour and apply a second coat if necessary.
If you find that the primer is not sticking, you may need to lightly sand the records with a 400-grit sandpaper to create a better surface for paint to stick to. This is not always necessary. Remember that multiple thinner coats of paint are better than a single thick, heavy coat.
Apply all paints and primers outdoors or in a space with a lot of ventilation.
