PHYSICAL PROPERTIES
Consistency: A smooth rubber-like
trowel consistency which will readily spread on and adhere to
vertical and horizontal surfaces without sagging.
Character of Dried Film: Excellent
adhesion to masonry, steel, cured concrete, shingles, asphalt
roofing, skylight flashings and a variety of other surfaces.
Film Performance Characteristics:
The dried film retains its elasticity and ductility so that the
material will resist extreme variations in temperature and weather.
Sag Resistance: Excellent resistance
to flow at high roof temperatures on vertical surfaces.
Homogenized: Thoroughly mixed
and consistent throughout.
USESKarnak
#19 Ultra Flashing Cement is a general purpose flashing cement for
repairing leaks in shingles, concrete, metal or asphalt roofs, flashings
on walls, chimneys, flues, skylight flashings, downspouts and cornices.
19 Ultra is excellent for sealing cracks in concrete and brick,
as a joint filler for precast roof slabs and for general purpose
use in maintenance of exposed buildings and structures.
