I have some paint splashes on concrete around my place. Can't get them off with a waterblaster or wirebrush, so paint stripper is next option. Are they all much of a muchness or not? eg is one of these better than another for this job https://www.bunnings.co.nz/our-range/painting-decorating/paint-accessories/paint-preparation/paint-strippers.

I'm pretty sure the paint is water-based, but can't be 100% sure.

Thanks for any advice.

That poly origional formula one has done everything I have asked of it, tried some other one thats not on the website and it was totally useless. Need good PPE with this, so a 3m organic vapour mask at least, if not a full face one.

Don't buy the Diggers. It's rubbish. It did take most of the paint off concrete, but only in combination with the water blaster. The Poly product works much better and most should come off with a scraper.

Thanks, SirHumphrey & richms. That's really helpful, I'll know to get the poly original now. Didn't realise I would need PPE for this stuff either. The Methylene chloride in this is pretty serious stuff, with many health hazards, from a quick google.

Depending how stuck on it is and how smooth the concrete is and how thick The paint is you could try a heat gun. It might peel off. Lot less toxic and messy.

Bit of a late reply but you could declare it a public amenity or something built by the council and the paint will start cracking and flaking off all by itself within a few weeks.
