Product and How to safely remove overspray paint

[misheycat]

 

What would remove house paint splatters from a colourbond fence and retaining wall?

I believe this is Taubmans snow drift paint, overspray from builders contractors 2-3 years ago from painting interior doors (they never bothered to come back and fix).

Is there a suitable product, method (eg. Paint or graffiti remover gel) that is both masonry and colourbond powdercoated fence safe (colour Riversand).

Welcome to the Bunnings Workshop community @misheycat. It's wonderful to have you join us, and many thanks for your question about removing paint.

You are right to be cautious here, because most paint strippers and graffiti removers are quite aggressive and there is a real risk they will attack the Colorbond powder coating or permanently stain the masonry. In general, there are no paint removers I would confidently recommend as being completely safe for both surfaces at the same time, especially given the paint has been on there for a couple of years.

The safest approach is to start with the least aggressive methods and work up only if needed. I would begin with a pressure washer, keeping the nozzle back slightly so you are not etching the masonry or damaging the fence coating. You may be surprised how much overspray will lift if it was only lightly bonded. On the Colourbond fence, after washing, you can carefully try a plastic scraper to see if you can lift the paint off mechanically. If it is interior door paint, it is likely a water-based or oil-based enamel and often sits on top of the powder coat rather than chemically bonding to it.

For the masonry or retaining wall, a stiff bristle brush combined with washing is usually the next step. Avoid going straight to a wire brush unless absolutely necessary, as it can leave visible marks on rendered or block surfaces. If you do consider a chemical remover at any point, it is important to test it in a very inconspicuous area first, as even products labelled as masonry safe can leave shadows or discolouration, and they are very likely to damage the Colorbond finish.

Overall, patience and mechanical removal is your best bet here. Start gentle, test small areas, and only escalate if you are confident the surface underneath will not be compromised.

Please let me know if you have any questions.

Afternoon @misheycat 

Because the paint has been there for so long I was thinking of another way you could remove the white from being so noticable.

How about a permanant marker pen? I know Officeworks have a large range that you get to try them out on paper first, or maybe a paint sample pot  of the two colours and dab the spots with a small brush? Tho they will age differently so fade differently.
