I am in the process of dry walling my mancave. So far I have taped all the joints and applied a second layer on all the joints with a curved trowel. I have noticed that the second coat has brought up a few bubbles in the tape I think I had the initial taping mix a bit too stiff only found out later that it should have been a bit sloppier.
Before I apply the third and final smoothing coat I am looking for advice regards the bubbles. My initial idea is to run a sharp blade along the crest of each bubble and squeeze a bit of PVA in. Alternatively I could mix up a sloppy mix of filler and trowel it flat.
Any ideas what you do to bubbled tape?
