Stud shadowing

4225 Views 5 Replies 6 Participants Last post by  welovepainting
Visited a homeowner to view and quote an interior repaint today and on the perimeter walls I noticed verticle stud shadowing on every wall, 6 years old house, looks as thought the homebuilder used a builders flat.
Tested for mildew and showed negative, house is clad in vinyl exterior.
Generally use a zinsser primer tinted and a Ben Moore top product for this type of repaint.
Should I or the homeowner be concerned with the shadowing showing through the existing topcoat?
I hardly see this when viewing houses for a repaint, and I don't know a lot about homebuilding, but my thoughts lean in the direction of either cheap paint or an insulation problem.
Any help or advice from you guys would be greatly appreciated.

Sounds like a simple case of dirty air, I see it sometimes on remolds or apartments where the people smoked alot, just prime and finish, should be fine.
If it was oil forced hot air heat, it could've been a small blow back
If it is, that stuff is tenacious and loves to leach through paint
Try and clean some off...see what happens
If it is blow back you're seeing, I've dealt with this a bunch. I usually tsp it, then problock it.
Often it shows an area of poor insulation and the dirt in the air sticks to the cold spots on the wall. I have had jobs where the studs and all the nailholes on exterior walls only where shadowed.

Agreed best route to go. I would use the oderless oil primer for stain blocking
