In 1998, 10,000 square feet of epoxy, decorative quartz flooring was specified for a vivarium at a major University on the West Coast. This installation was performed by the material manufacturer’s certified contractor and was completed in November 2000. A few weeks after installation bubbles and blisters appeared. When the blisters were punctured they contained liquid. As anticipated, the moisture vapor emissions were confirmed to be 4 to 9 lbs in excess of the manufacturer’s recommended maximum of 3 lbs
In 1998, 10,000 square feet of epoxy, decorative quartz flooring was specified for a vivarium at a major University on the West Coast. This installation was performed by the material manufacturer’s certified contractor and was completed in November 2000. A few weeks after installation bubbles and blisters appeared. When the blisters were punctured they contained liquid. As anticipated, the moisture vapor emissions were confirmed to be 4 to 9 lbs in excess of the manufacturer’s recommended maximum of 3 lbs. No moisture emission testing was done prior to installation. To correct this problem, the flooring system was completely removed. A Silicatebased penetrating moisture remediation system was selected and installed prior to reinstallation of the specified quartz system. In all but one room, cage wash, this remedial system controlled the excess moisture. In the cage wash room however, bubbles and blisters reappeared. This paper addresses the permanent solution used to correct the problem and the need to fully understand the environmental conditions of the facility prior to selection of moisture remediation systems.
A five-year coatings research project was initiated by the Pennsylvania Department of Transportation in 1986 to evaluate the performance of an organic zinc rich coating system. The coating system consisted of a moisture cured urethane zinc rich primer, an epoxy intermediate, and an aliphatic polyester urethane finish coat. The system was applied to the Windgap Bridge located in McKees Rocks, Pennsylvania (near the City of Pittsburgh) in 1986 and 1987.

A continuing problem with coatings applied to sharp edges of a structure is the corrosion that often develops at the apex of the edge. The conventional wisdom is that the reduction of film thickness, due to coating pulling away at the edge during the curing of the coating, is the primary cause for the onset of corrosion. This theory, however, is not necessarily correct, both from a mechanistic and practical point of view.
Now more than ever, epoxy coatings on concrete will only prove successful if diligent care is given to the details of concrete preparation. Preparation is more than grinding or facing of an existing surface and should ideally begin in the developmental stages of the structure.
