I originally planned on using melamine for my in wall shelves that housed my tv, components, and dvds. I was going to get 3/4" white melamine. We (wife) wants to have white shelves and white trim so I thought purchasing melamine would cut down on painting/staining anything else that we would buy. Plus I've heard that is what others are using. Now, I've called my local lumberyard and asked them if they had it. They (Carter Lumber) said they had showerboard (basically same stuff I thought) in 3/4" thick sheets for $10.99. I thought great...good price and 5 minute drive from my house. I went up there this weekend and said I needed 6 sheets and they told me they didn't have any. Wtf?? So I went out to my other lumber yard and they didn't have anything either. So now, I was thinking of getting mdf and painting it white. Can this be accomplished?? mdf at home depot is $13 while the melamine is $25. Do you think buying the melamine from hd for $12 extra dollars is worth the time and paint for the mdf? Sorry for long post. I'm a little upset with these damn lumber yards.
