[Deck paint advice please]

Hello,

I recently bought a narrowboat (22ft) and I have been doing some work on her. The front deck needed some cleaning / derusting / welding - which is now done. I have paimted it with Owatrol and with red oxide but now I need to put the top coat on so I can finally take off the tarp which has been protecting it ip until now.

 

Please can anyone here advise what paint I should use? I want to paint it black and although I have been recommended "International" it doesn't come in black. Someone else just said to use Dulux exterior gloss or I've heard you can mix it with sand? I'm not sure what to do and I don't want to mess it up.

 

Hope to hear from you soon.

 

Lynne
