|
Application. Industry
experience demonstrates that an effective method for achieving a visually uniform surface for both
the primer and topcoat is spray application immediately followed by back rolling or roller application
using good roller techniques, such as finishing in one direction and using roller types and naps
recommended by the paint manufacturer. |
|
Environmental Conditions. Follow
the Drywall Finishing Council's document titled, "Interior Job Condition Specifications for The
Application of Drywall Joint Compounds, Drywall Textures, and Paint/Coatings". |
|
Gypsum-Board Preparation. To
achieve the desired level of paint finish over gypsum wallboard, the substrate must be finished
appropriately. Refer to Gypsum Association GA-214-96 titled "Recommended Levels of Gypsum
Board Finish". |
|
Job Standard Specification. To
improve communication, a job standard of the approved paint system shall be established to provide
for a visual sample, constructed and finished in accordance with applicable project specifications.
As a guideline, refer to PDCA P5-94 titled "Benchmark Sample Procedures for Paint and Other
Coating Systems" for a detailed description. |
|
Paint Selection. Manufacturers
produce various paint grades and types. When the level of finish is selected, consult with the paint
suppliers to determine the products that will produce the desired finish. |
|
Texture. Texture,
as referred to in Level 3, is a dimensional effect that becomes an integral part of the properly
primed substrate. Note: Topcoat materials used as a texture shall be referred to the appropriate
level of paint finish. |
