Two coats of primer and thinking about a third...?
 

I have new drywall and have primed with two coats of BM super spec. After the second coat the tape joints, pencil marks and color of the green board (blue board in this case) are still showing through. Is this normal or should apply another coat of primer?

Perfectly normal---the primers job is to seal the surface and provide a good bond between the surface and the new paint----

It's not a paint and 'see through ' is fine---one very popular primer -Guards--is clear---

A very light sanding to knock off any boogers is a good idea---Mike----

Don't put on more primer. Paint it! Paint has more pigment and will do the hiding.

Normal routine is one coat primer ( Lightly sand) 2 finish coats

Normal to see the joints showing through as the primer soaks into the mud differently than it does on the actual blue board.

As BJ said, lightly sand, remove any excess dust from the sanding, and, apply your finish coats.

Some times on new drywall, a high build primer is used to raise the finishing level (Level 4 or 5), where the joints do not show. As stated , the paint finish coat should provide the hiding.

yup one coat. next time get your primer tinted close to the color your going to paint the wall so you dont see through the drywall so mentally you feel better and to not think it needs a second primer coat.

Yea primer is meant to BOND or SEAL or SMOOTH OUT(undercoater). Its not what hides the color underneath. Some do cover better though.
