Could someone give me ideas on how to paint a rusty fridge please. Any kind of advice would be much appreciated.
If you've rubbed back the rusty spots to bare metal, you're ready to apply the paint according to the instructions. If a separate primer is required, it would state it in the instructions. Not all paints require primers as they include bonding agents within the paint.
After the weekend, I'd be happy to contact White Knight for you to confirm that a separate primer is not required. I can't advise using a separate primer at this stage, as it would contradict their instructions. I'd also be concerned about the compatibility of the primer with their product.
I'll wait for your reply before I go any further.
Many thanks for your patience, @eriswa.
I've been able to confirm that unless you're painting the whole panel of a fridge that is currently bare metal, then there is no need to prime the area. If you are still at all concerned, you can use an SLS Etch Primer on the exposed metal portions.
Please let me know if you have any questions.
Thanks for doing that for me, very much appreciated.
Please keep us updated with your progress, we look forward to seeing your fridge freshly painted.
Thank you very much to both you and Mitchell for all your help and advice, will definitely keep you posted with the finished product.
HI Eric I finally finished the painting though the weather wasn't the best for it. I ended up using Rustoleum instead of WK, due to unfavourable reviews on WK. I ended up doing 4 coats as some of the very bad rust spots I rubbed back didn't cover. I started a 5th on one side and and it bubbled in a few spots so I stopped doing the rest. I sanded it back and left it as it is, quite happy with the overall result though. Being a spare in the garage so I wasn't too fussed.
Sending you some pictures. Thanks once again. Cheers
Thank you very much for posting those photo updates of your fridge. Your spray painting looks good and the fridge looks brand new again. Wrinkling is often caused by unequal drying during the painting process. From the surface, it looks like the paint is, but underneath that dry surface, the paint is still wet. When a new coat is applied the semi-dry paint moves as it continues to dry causing wrinkling to occur.
My only tip is to give the paint a few extra days to dry off, one of the best ways to tell is to gently touch the surface of the paint and if it feels like it's sinking the paint underneath is still wet. Don't be tempted to use a hairdryer or a heat gun as these tools will only dry off the surface and not cure the paint underneath.
Again, thank you for sharing your fridge painting project.
I've lightly sanded back the wrinkling as you called it and left it as it is, it doesn't look too bad. I'm not going to repaint it at the moment, maybe later on down the track when the weather gets a bit warmer.
It's only sitting in the garage and I'm quite happy with the final result.
I totally agree with your plans, unfortunately, this cold weather is really not ideal for any sort of painting as it really delays the drying time.
We look forward to seeing your next project.
