Is it best to prime new drywall??
Should we request that he prime than apply a coat of paint or just let him apply two coats of paint? Thanks for any assistance.
The primer does several things. 1 - seals the drywall and mud much better than paint.
2 - creates a surface for the paint to adhere better. 3 - Witout it, you will see a difference between the mud and the drywall. Those materials absorb the paint differently. You WILL see it when the light is at the right angle.
