DRY FOG FLAT
Tuff-Boy 999 Water-Based Dry Fog Flat is a high hiding coating formulated for
interior application via conventional or airless spray equipment only. This coating
will not yellow, is low VOC, and has no harmful solvent odor which will allow
one to spray in areas while people are still working. Tuff-Boy 999 will reduce
lighting requirements and is ideal for commercial and industrial areas where dry
overspray characteristics are desired. Overspray from Tuff-Boy 999 does not
stick, but falls to the floor as a dry dust which may be swept up without damaging
the surfaces on which it has fallen. A small test area should be tried before
spraying a large area to make certain that overspray does not stick to the floor.
Sometimes unusual conditions exist such as excessively high humidity, that could
make overspray stick to uncovered surfaces. Because Tuff-Boy 999 is a water-
based dry fall coating, a large amount of moisture is released into the atmosphere
during application. Proper ventilation is required to ensure that humidity levels do
not increase to the point that dry fall no longer occurs.
This product is recommended for properly prepared interior ferrous or galvanized
metal, aluminum, wood or masonry surfaces. Tuff-Boy 999 is ideal for use on
large commercial ceilings such as those found in manufacturing, warehouse or
industrial areas. This product is also suitable for use on properly prepared
structural steel, piping, beams, girders, or trusses.
Primers are not normally needed on interior applications. If the ceiling to be
painted is to be exposed to excessive moisture or mild chemical fumes then we
recommend that one prime ferrous metal surfaces with Tuff-Boy Rust Stop
Primers (#1024 Red or #1069 Gray). Prime aluminum and galvanized, surfaces
with #5-56 100% Acrylic DTM Primer.
The surface to be painted should be d
