ICI Dulux Vapor Barrier Primer Sealer
A special latex primer-sealer and vapor barrier for
interior walls and ceilings. It reduces loss of interior
moisture through the walls to help maintain insulation
efficiency and guard against exterior paint adhesion
failures caused by condensation. Moisture and Heat
Loss - Every home contains moist air (water vapor)
that, in the proper proportion, provides a healthy
atmosphere. But under winter conditions, when
the inside/outside temperatures differ drastically,
the moisture indoors passes through interior walls
and condenses within the stud space as it seeks
the colder exterior side. The moisture may fill the
pockets or voids in insulation, increasing the flow
of heat, reducing its insulation value. Insulation
must be dry to function efficiently.
Keeping water vapor inside the home will help reduce
heat loss and guard against moisture damage. Vapor
barrier systems can help to provide this protection.
Therefore, to help keep moisture inside apply ULTRAHIDE
Vapor Barrier to interior walls and ceilings that
contact the outside of any unheated areas. To be
effective, a product must have a perm rating of less
than 1.0, as set forth by the Federal Housing
Administration Minimum Property Standards.
ULTRA-HIDE Vapor Barrier is specifically formulated
to provide a perm rating of 0.6 when applied at a
coverage rate of 400 sq ft/gal (10 m2/L) to smooth
surfaces.
