Dry wall seems that appear oily after primer and paint?

by Mdbc77
We recently put up new dry wall. We primed it and painted and were surprised to have the seems appear oily/shiny. It's very visible. I'm beginning to see shiny spots where the nail holes were, too. Any idea what could be causing this and how to fix it? I thought the drywall compound might have gone bag? Or there is a bad reaction between the drywall compound and the primer? Not sure what drywall compound was used, but we used Valspar Contractor Primers: Interio, PVA Primer.

  • If the walls are new and the areas where the spackle and nails appear to be shiny it is caused because the spackle is of a different texture and absorbs the paint at a different rate then the drywall itself. If that makes sense. If you use the same paint on different materials you will see different finishes when dry. Some shiny some dull. If you let this dry real well and prime again, it should all look the same. This is the very reason why we prime before we paint. To seal the surface so the finished paint does not have different appearances due to the paint being absorbed at different rates on the surface.

    fantastic! i had never thought about drying time. will have to google the amount of time it takes the drywall compound to really dry, for furture ref. i'm sure we did not wait long enough...not very patient with waiting! i will give it another coat of primer this weekend and wait a little while before repainting, just to be on the safe side. i am so glad you answered my post! and i'm even happier that sandra from saw dust and paper scraps recommened posting here! THANKS again!

    want to try this suggestion and post back if it works! fingers crossed!
  • Drywall compound takes several days to really dry out. Most pros use the bag type that we mix with water and hardens faster and drys faster also. The stuff you get out of a bucket premixed has chemical additives mixed with it to prevent fast evaporation or otherwise it would dry up to fast in the exposed bucket when you were working. This however also prevents it from drying as fast on the wall. Your issue is that the drywall is absorbing the primer at a different rate then the spackle. Because of this the final finish will look different. Once the primer dries properly this will prevent future coats of paint from being absorbed thus the final finish should all look the same. Two coats of primer is fine, but if you properly applied a sealer first before priming you do not need to do this. No sealer, then two coats of prime is in order.

    hmmm...did i spell seem wrong. was just reading the reply and got to thinking it should have been seam? anyhoo. i did not know i should use a sealer over the drywall compound/spakle! we obviously didn't use any and we only put on one coat of primer! guess, i'll just go ahead and reprime and paint the whole room. it needs another coat of paint anyway, wish someone would have told me that light blue would show up every little hand print, and i still don't know how they get the foot prints on the walls! thank you so much for sharing your knowledge!
  • Well if your living in ky all the land is on a hill, so you sure the wall is not the floor? lol Wife and I spent several days looking in Boone County up north for a farm. Not the greatest place to have a horse. As far as sealers, Yes they make a new drywall sealer that prevents the prime coat from soaking in to much. It tends to be on the clear side when it goes on. 2nd coat of prime should be fine.
