I need some help quickly! I have had a misunderstanding with a homeowner. Somewhere in a conversation we discussed using blueboard (used for plaster finishes) in a kitchen and having a smooth coat drywall finish (finished like sheetrock). I thought that drywall finishing blueboard was a bit weird and the finisher kept asking me if it was okay to mud over this product. I had thought the homeowner wanted this because it was in a kitchen … somewhere the ball was dropped.
This is my question. Can blueboard that has been taped like sheetrock be painted without any damage to the walls? I feel that the only major problem would have been the seams, which look good to us, being wavy. He, the homeowner, feels that the components (drywall mud and blueboard material) are not compatible. I think that with a primer coat and 2 finish coats of paint, it won’t matter at all. The mud is sticking like glue to the board.
Please help me out. I need to know what you all think. We will be “chatting” about this project on Monday morning. The attached photos can’t give you a feel of the materials but it shows the lack of wall humps.
