We've been in our house for 4 years. We have vinyl and carpet throughout. I recently decided to remove it all except the carpet in the bedrooms. I've scraped and ground glue for weeks. Finally we've got it done. I must say that the floors look amazing. We we're able to use the standard acid stains. We used a new Semi transparent stain put out by sherwin williams under the H and C line. I'll post pictures and a how to guide if any one is interested. I've always wanted stained floor but thought it impossible due to having glue down vinyl and over spray all under my carpet from the construction process.
