The staining problems on the walkways and stairwells has been caused by the solvent based clear top coat attacking the sub finishes & caulking.
Gulf Coast Water Proofing's solution is to seal the current surfaces a water based epoxy coating. This will serve as the new bottom coat. Next an acrylic based material will be applied, followed by a clear acrylic top coat. A test area has been designated on the 8th floor, East Tower. The test could start as early as this Monday, and will take two days (much shorter than the prior estimate of 4-7 days) to apply. After an appropriate monitoring period, and assuming there aren't any problems, all the walkways and stairwells will be redone.
