Referring to the suttle black discoloration appearing thru the off white ceiling where the sheet rock meets the wooden trusses. I contacted a local building inspector and he says where the wooden trusses meet the sheet rock is the coldest part of the house and moisture is being drawn up thru the sheet rock to the trusses. He suggested paint the ceiling w/kilz primer and and repaint. The Kilz primer acts as a vapor barrier. Is this true?

Yes it is true... Kiltz at one time only made primers... Today they produce paints of all types. Be sure to read the can and buy the correct product.... They person who services the paint counter will know just what to use.

Never heard it being a vapor barrier. Your problem is not coming from inside the house. Make certain the soffit's have no obstruction and air is permitted to circulate thru the space above the ceiling.

Benthere - you are the 2nd person to agree by using Kilz primer paint, it will stop the black blemishes appearing where the trusses meet the sheet rock. I was told this is due to lack of insulation at the point of contact.

Are you a building or a general contractor?
