Refinishing Wood Table--scratches after first coat of stain
First time DIY-er and I am refinishing a table for my wife. I used a rotary sander and smoothed everything out...felt nice and smooth, but after I applied the first coat of stain I noticed circular scratch marks all over the table!
My question--do I need to sand the entire top again? Or--can I just sand the areas where I see scratches (about 1/3 to 1/2 the table I apparently went against the grain!).
Also, would you use a finer grit like 220 to redo it? OR...do I need to do a 80/100 first and then do the 220?
Thanks for any help!
