Mix a gallon of water with a cup of bleach and a tablespoon of liquid soap. Wash the chairs and let them dry. You can buy spray paint that is 'multi-surface' that can be used on resin chairs.
Hi Susan: What I did was to wash my chairs with soap and water. I let them dry and then painted them with a spray paint. I have used both Rust-Olium and Krylon spray paint for plastic with great success. I painted the undersides and legs first, let that dry over night and then painted the top side. It's lasted for a couple of years, so far:) I used yellow! Good luck
Hi Susan, I hope this information helps you get your patio chairs in shape for the summer.Spray Paint Project Steps
Using an all purpose cleaner/degreaser, wipe down chairs to remove all dirt and grime. (If the plastic is new, wipe down with paint thinner for best results.) Rinse thoroughly with water and allow to dry. We painted one chair in Gloss Popsicle Orange and the other in Gloss True Blue.

Spray Paint Project Steps

I pressure wash them. But you need to find something to anchor them in place sort of or you will chasing them all over.
The day after washing I sand them lightly. That is just so the paint has something to hold onto.
Then I just apply many very light layers of spray paint. I allow at least a half an hour in between coats.
When I did mine, I sprayed with the "jet" setting after spraying with a degreaser. Then scuffed with steel wool for the paint to adhere. Wipe down with denatured alcohol. Spray painted with a formula paint for that type of surface.
Yep power wash them and spray paint in a color you like.
Here is some information:
Here is more info for your resin chairs
I had painted some Adirondack chairs that were vinyl resin and they only lasted a couple years with the plastic friendly primer+ spray paint formulations.
I believe jar formulations might be a better choice. But I would call the various paint manufacturer and get the details for best possible options or find a recommendation here before investing the time and money and having a result you’re not happy with.
