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

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.

3. For best results, apply the high solids primer with a

(10 mm) nap roller at a natural application rate.

4. It is possible to use 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.
