Sandpaper grit needed

What grit sandpaper should I use to prep the surface for adhesion of the new paint ? I'd start with 150 grit, see how it goes. Anything finer won't cut fast enough. You might want to try an "open coat" paper that won't clog with paint too fast; normally when deglossing paint, the paper gets clogged or loaded before actually wearing out. If the paint surface is already dulled in some spots from weather, you don't really have to sand it. All you're doing is "scuffing" to paint so that the new paint will adhere to it. You are going to use primer first, right? Tip: If the paint is a dark color, get the primer tinted (gray) so you're not painting a dark color over white. I did this recently on a wrought-iron fence, dark green, and the paint covered in one coat. -- Any system of knowledge that is capable of listing films in order of use of the word "****" is incapable of writing a good summary and analysis of the Philippine-American War. And vice-versa. This is an inviolable rule. - Matthew White, referring to Wikipedia on his WikiWatch site (http://users.erols.com/mwhite28/wikiwoo.htm) 150g would be a waste of paper and time, time is money on a iron fence that will take forever anyway. |
