Re: Repainting my deck?
Like already said, can't give you advice without furthur information on what is existing. But, that being said, any paint is only as good as the preperation before hand. Degreasing/cleaning and sanding the surface wether it be existing gelcoat,paint or other material is a must for proper adhesion, especially when talking exterior applications or walked on surfaces.
You want a nice looking deck, you have to be willing to pay for the work or be willing to do it properly yourself.
If you slap something on your deck without the proper adhesion/sanding, it will look great for atleast a week! until it statrs to peel or flake.
Good luck.
if you really want the best advice here, I suggest you post some pics of what your deck looks like now.
