water stained colourbond fencing / privacy screen

[KrustyB]

Is there a repair or cleaning option for water stain on  colourbond privacy screen? 

 

Removed these painted aluminum privacy screens to complete another DIY task, but where I stored them they became wet and hence the water stains.

Is there an option to clean the stains…. Or am I going to have to repaint?

Hi @KrustyB 

Water stains should come off colour bond for  the most part it is probably lust  some mineral depisits out of the water.

Try Cleaning  with CLR  Calcium Lime Rust  remover you might need to do this twice spray it on metal and let it sit will let the CLR  work. For 20 mins.

Hi @KrustyB 

Any  remaining lighter stains  try some bleach.

Worst case  scerio just buy some white spray paint Or any colour you wish to change to .

Just do light even strokes like  painting with a brush start spraying (push the button) at the top  and stop at  the bottom.

Hope this nails it for you.

Unfortunately neither CLR or bleach worked. 

I suspect I am heading down the path of repainting.  It’s a rather large area so will need to hire a spray gun. 

I’ll keep an eye out for further advice in case something else is suggested 

thanks again

Hi @KrustyB 

So @KrustyB   It didnt work  even with a little saoking  time?   You  probably have bleach in your cupboard it should take on a world of staines but maybe not 100%

I would  suggest you buy a  good quaility  every day spray gun that wont break the bank.  That way you have it for future  projects.

The money you spend on hire is going to be in the $100 range, so an extra $50 is not a lot for a new spray tool

I am going to buy to do my fences with the one below.   Just add 10% water to regulaer acrylic paints for best  paint flow.
