Self leveling intumescent caulking applied in a wall in the <a href="//commons.wikimedia.org/wiki/Grand_Coulee_Dam" class="mw-redirect" title="Grand Coulee Dam">Grand Coulee Dam</a>. The sealant runs out before curing and the <a href="//commons.wikimedia.org/wiki/Firestop" title="Firestop">firestop</a> remains inoperable. Self-leveling caulking is better for floor applications. Alternatively, one can turn the dam 90° prior to the installation.
