Please no B&Q decking jokes as I've heard them all 
Right I need to repaint my decking in the garden. At the moment I'm sanding it down but then need to repaint it.
Do I need to buy a seprate sealing paint or buy a decking paint with it in?
Can you recommend any good brands? Or process for re-painting it?
