| Delamination of
texture on drywall surfaces is an expensive and apparently increasing problem. Job site
investigation of this problem reveals not one cause, but
several. Read more >>> |

| Recommended Paint Finish Over Drywall (Page 1) (Page 2) (Page 3) |
| 3. Recommended Levels of Paint Finish over Gypsum Board. The
following levels of paint finish are established as a final decoration guide. |
|
Level 0: |
|
No painting required. |
|
Recommended where final decoration is not required. |
|
Level 1: |
|
a. When final decoration is
undetermined, all appropriately prepared gypsum board surfaces shall have one coat of drywall primer
applied. Drywall primer shall be applied to the mil film thickness and application conditions specified
by the primer manufacturer. |
|
-Or- |
|
b. When wallcoverings
are to be applied, all appropriately prepared gypsum board surfaces shall have one coat of wallcovering
primer applied. Wallcovering primer shall be applied to the mil film thickness and application conditions
specified by the primer manufacturer. |
|
Level 2: |
|
All appropriately prepared
gypsum board surfaces shall have one coat of topcoat material applied to yield a uniform surface. Paint
shall be applied to the mil film thickness and application conditions specified by the paint
manufacturer. (The painted surface may not achieve uniform appearance,
color, or sheen, but shall be absent of defects caused by the painting contractor's workforce.)
Recommended
where economy is of primary concern. |
|
Level 3: |
|
All appropriately prepared
gypsum board surfaces shall have two separate coats of topcoat material applied to yield a properly
painted surface. Paint shall be applied to the mil film thickness and application conditions specified
by the paint manufacturer.
Typically recommended for
areas having textures (spray or hand applied) over a primed gypsum board surface and the area is not
subject to critical lighting. Refer to Drywall Finishing Council document titled, "Recommended
Specification For Preparation of Gypsum Board Surfaces Prior To Texture Application"
When
subjected to critical lighting, a Level 5 gypsum board finish as defined in GA-214-96 is recommended. |
|
Level 4: |
|
All appropriately prepared
gypsum board surfaces shall have one coat of drywall primer applied to yield a properly painted surface
and one separate coat of topcoat material applied to yield a properly painted surface over the drywall
primer. Paint shall be applied to the mil film thickness and application conditions specified by the
paint manufacturer.
Typically recommended for smooth
surfaces not subject to critical lighting and areas having light to medium texture finishes (spray or
hand applied over a primed gypsum board surface). Refer to Drywall Finishing Council document titled
"Recommended Specification For Preparation of Gypsum Board Surfaces Prior To Texture
Application".
When subjected to critical lighting, a Level 5 gypsum board finish as
defined in GA-214-96 is recommended. |
|
Level 5: |
|
All appropriately
prepared gypsum board surfaces shall have one coat of drywall primer applied to yield a properly
painted surface. Two separate coats of topcoat material shall be applied over the drywall primer
to yield a properly painted surface. Paint shall be applied to the mil film thickness and application
conditions specified by the paint manufacturer.
This
level is recommended where the best paint finish is required, such as under critical-lighting conditions
or when paints that have a glossy surface are used. Recommended with a level 5 gypsum board finish as
described in the Recommended Levels of Gypsum Board Finish. This system, when combined with the Level 5
gypsum-board finish, is the most effective method to minimize joint and fastener photographing and provides
the most uniform final finish. |
