Primers are the undercoat used for paints and a drywall primer is just one that s formulated specifically for applying to sheetrock. Once dry the joint compound can be painted with latex paint and glazed for additional dimension. After you re done hanging drywall and all the seams are taped and finished you need two coats of paint to give the wall its final appearance. If you have ever looked at a painted wall from a sharp angle and seen the finished joints show through this is an effect called joint banding or flashing.

Apply a latex primer to drywall as oil based primer can raise the grain and make the surface look even. Drywall primer soaks into the paper scuffed paper and mud the areas of differing porosity and creates a uniform surface to which the finish paint can adhere. This difference in porosity can cause blotchy dull areas under the paint a problem called flashing and an inconsistent sheen. All the glue must be removed to get the paint to stick even it you need to get below the first part of the paper.
