Can you paint upholstery with normal spray paint from the hardware store? Such as Acrylic or oil base?

I wouldn't recommend paint. It would make the surface very uncomfortable for seating. I suggest buying fabric dye (Rit brand for example), and mis it in a bucket. Use rubber gloves and a sponge and dye the fabric instead. I did this on a cream colored couch and it worked perfectly. Be sure to read the instructions for setting the dye and also protect any other surface where you are working. Be sure not to overly wet the upholstery and it should dry in a reasonable amout of time. Good Luck!! Also, the color did not transfer onto any other clothing or surface after drying!
