The only way I've found is to take a box cutter and cut the delaminated
paper away. For example, if you have a quarter sized area that is bubbling,
take your knife and cut out the paper for a 1/2 inch all the way around the
bubble. Go ahead and cut down into the limestone and dig a little of that
out too. You need to remove all of the delaminated (bubbling) paper.
This can be a long process. You fill, find a bubble, cut it out, and fill
some more.
