Evaluate your furniture
Take a good look at your furniture and decide if painting or staining is even worth it. You can certainly fix a wobbly chair or repair scratches and dents, but if a chair is rotted or the plastic leg of a table is cracked and falling apart, it may be time for new furniture.
If your furniture is metal, you can paint over rust. First, remove all the rust before painting. You can do this without chemicals – you’ll just need to grind, scour and sand off the rust with a tool such as a sander, oscillating tool or drill.
Remove loose paint
If you’re painting or staining wood or metal, you’ll need to remove any loose or peeling paint from both the furniture and any hardware before applying on a new coat. Try using sandpaper and a little elbow grease for this job.
