How to Cover Shiny Spots on Drywall
Shiny spots on drywall form when something shiny bleeds through paint on top of drywall or when the wrong type of primer is used. If you paint over drywall that had grease or crayon stains on it, the shiny grease might bleed through the paint without a coat of stain-blocking primer under the paint. On the other hand, spots of stain blocking primer over individual spackled areas can cause shiny spots under paint. Does this Spark an idea?

1
Sand any imperfections in the surface of the drywall, such as mud or spackle used to patch holes. The sandpaper will help create a uniform surface so no specific areas become shinier than others.
-
2
Cover the entire surface of the drywall with a stain-blocking primer, if the wall has grease, crayon or other shiny stains on it. A stain-blocking primer will prevent grease stains from soaking through the paint and causing shiny spots on the wall.

3
Coat drywall that does not have stains with a regular drywall primer before painting. Cover the whole wall to ensure an even base coat for paint. Use a latex-based primer to avoid an uneven finish.
-
4
Use a regular drywall primer for touch-ups. Do not use a stain-blocking primer over patched areas on drywall; only use it to cover an entire wall. Patches of spackle or patched-up drywall will look shinier than the rest of the wall if they have a stain-blocking primer when the rest of the drywall has regular primer.

5
Use a metal primer to cover shine from nails, staples or other metal in the drywall.
