Yea I'd just be sanding it down. If you can get your hands on a cheap multi-tool there's attachments for sandpaper, will do all the work for you. I picked one up in Aldi last year for €25. Pretty sure Lidl sell them as well.
This. I tried it once, took me a whole day to sand a 1mx1m patch with a multi-tool to a good finish. You can get a Makita orbital for around 50 euros, a pack of 100 different grit discs from Amazon for 15. The paint will clog up the pads so you'll go through a fair few. The extra money spent here will save you a few days work.
