Dormitory Building at University of North Dakota
Grand Forks, ND
A portion of the textured acoustical ceiling in the stairwell of a dormitory at the University of North Dakota had become damaged to the point where the asbestos containing texture along with Lead-Based Paint on the surface of the textured ceiling, was crumbling off onto the stairs below. Removal and replacement of the textured ceiling was considered prohibitively expensive ($7-11 per square foot)
A decision was made to use encasement to eliminate this hazard. SE-110 Penetrating-Stabilizer (primer) was first applied onto the entire stairwell ceiling to stabilize this surface. Next, the damaged areas (with visible profile differences) were built up with SE-150 architectural sealant, after which the entire stairwell ceiling was sprayed with SE-120 Protective-Skin topcoat. Finally, to make the patched area less conspicuous, some grit was added to a quart of SE-120 topcoat that was then brushed over the patched areas to create a textured appearance. The estimated cost of encasement and repairs in this area was in the range of $3-4 per square foot, including containment.
