Trapped water blisters.

It is normal for some blistering to occur It is normal for some blistering to occur. A small number of blister heads should be sampled and checked for proper membrane thickness. If the samples have the required membrane thickness (80 mils nominal/60 mils minimum), then the remaining blisters should not be punctured or cut. If the samples have less than the minimum 60 mils, then the area can either be re-sprayed to obtain the proper thickness. Or the blisters can be cut out and the area re-sprayed or patched with Liquid Rubber Trowel Grade, to a minimum thickness of 80 dry mils over the cut-out area extending a minimum of three inches (3") beyond the cut.
