Georgia-Pacific DensArmor Plus Interior Panels - Manual

A mock-up or test wall should be used to ensure the proposed
decorative finish will produce an acceptable result. Proper
installation, finishing and priming are critical. Skipping a step,
such as the application of a primer, or taking shortcuts, such as
not using proper sanding techniques, will negatively impact the
quality of the final decorative finish. Because many factors that
are unrelated to the manufacture of the panels can affect the
acceptability of the final finish result, Georgia-Pacific Gypsum
makes no warranty, express or implied, regarding the finish
results to be achieved with DensArmor Plus
® panels. The following
guidelines for priming DensArmor Plus Interior Panels have
been developed by the Rohm & Haas Paint Quality Institute.
For best results, please use the following steps for priming
DensArmor Plus Interior Panels.
1. A high solids primer with at least 40% volume solids
should be used. The primer can best be applied by roller at a
higher film thickness in one coat. (vs. brush or spray applied)
2. For adequate coverage, the primer should be applied to
a dry film thickness of 1.7 to 1.8 mils dry to ensure uniform
coverage and appearance. The number of coats to achieve
the dry film thickness will depend on the primer used.
For instance, a primer with lower than 37% volume solids
may need two coats for adequate coverage.
% Volume Solids Spread Rate,
of Primer square feet/ gallon
37 330-350
40 355-380
43 380-400
47 420-450
3. For best results, apply the high solids primer with a 3 ⁄
8 (
(10 mm) nap roller at a natural application rate.
4. It is possible to use a 1 ⁄
2 ( (13 mm) nap roller and apply a
thicker coat. However, the roller pattern is more
pronounced and some may find it objectionable.
5. To maximize the mold-resistant benefit of the DensArmor
Plus Interior Panels, a 100% acrylic primer with mildecide
should be used.
6. High-quality flat or satin paint should be applied over
the primer. Semi-Gloss or Gloss paints are not
recommended.
