Okay, so I have primed the room. One gallon got me one full coat. I can still see some of the original light blue through the white primer. I am going to paint it light brown...like a "toasted cashew" color. Do I need a second coat of primer? http://www.myperfectcolor.com/Match-of-Ralph-Lauren-NA05-Tangier-Island-p/mpc0068281.htm" [Broken] is the desired color. http://www.myperfectcolor.com/ProductDetails.asp?ProductCode=MPC0006740" is the current color. (Before priming) Also...you know that ever-so-slightly 'textured' look that a roller leaves? You know...it's slightly 'bubbly'.... Is there any way to avoid this? It seems unprofessional looking to me;not that I'm a pro. I just think it could look better. How do pros get a smooth finish? Is it the quality/material of the roller I am using? Thanks for your opinions!
