Hi,

I just had some work done in my kitchen which included some wall
repair. The contractors fixed the drywall and laid a couple of coats
of mud (the contractors are gone and are not returning). I put on
what I hoped was a final coat of mud and sanded. I didn't notice any
bubbles at this time. I then put on a water-based primer and I saw
some bubbles arise. I realize this is bad, so I sanded down as much
of the mud as I could (the paper started to shred). The tape appears
flat, but I can press in some of the paper in areas of the repaired
wall joints. From some posts I have read in this group, I guess the
water in the primer soaked into the tape and caused the bubbles. So
what do I need to do? I think if I continue sanding I will start to
rip the paper. Can I use an oil-based primer to lock down the paper
and tape? Then lay some more mud, sand and prime (oil-based this
time!)? Will this work? Any advice would be appreciated.

thanks,

Brendan
