PART 3 - EXECUTION
3.01 EXAMINATION
A. Examine substrates and installation
conditions to ensure surface conditions meet or exceed a Level 4 finish,
GA-214-M-97, Recommended Levels of Gypsum Board Finish.
B. Test
substrates with a suitable moisture meter and verify that moisture content does
not exceed 4 percent.
C. Verify substrate surfaces are clean, dry, smooth, structurally sound and free from surface defects and imperfections that would show through the finished surface.
D.
Evaluate all painted surfaces for the
possibility of pigment bleed-through.
E.
Notify the contractor and architect in
writing of any conditions detrimental to the proper and timely completion of the
installation.
F.
Beginning of installation means
acceptance of surface conditions.
SELECT INSTALLATION FOR WALLCOVERING BACKING
OR ADHESIVE BACKING
3.02 INSTALLATION Wallcovering backing.
A. Acclimate wallcovering in the area of
installation a minimum of 24 hours before installation.
B. Read and follow the instructions in the manufacturer's installation sheet contained in each roll of the dry erase wallcovering.
C. Examine all materials for pattern, color, quantity and quality as specified for the correct location prior to cutting.
D.
Adhesive:
Use heavy-duty pre-mixed strippable clear or clay-based vinyl adhesive, such
as: Koroseal A-848-B or other high quality adhesive recommended for fabric
backed vinyl wallcovering and approved by manufacturer.
E. Primer: Use a pigmented primer on deep colored walls and walls with contrasting colors.
F. Install each strip in the same sequence
as cut from the roll.
G.
Install dry erase wallcovering panels in
exact order as they are cut from bolt. Reverse hang alternate strips. Do not crease or bend the wallcovering when
handling.
H.
Install dry erase wallcovering
horizontally using a level line. Using
level or straight edge, double cut the seam with a new razor or knife.
I.
When covering the entire wall, seam the
material out of the main writing and viewing areas of the wall.
J.
Smooth wallcovering to the hanging
surface using a wallcovering smoother, wrapped with a soft cloth, to eliminate
air bubbles, wrinkles, gaps and overlaps.
Do not use sharp edged smoothing tools. Smooth material on the wall from
the middle to the outside edge.
K. Remove excess adhesive along finished seams immediately after each wallcovering strip is applied. Clean entire surface with warm, mild soap solution, a natural sponge and clean towels. Rinse thoroughly with water and let dry before using. Change water often to maintain water cleanliness.
L.
Stop installation of material that is
questionable in appearance and notify the manufacturer's representative for an
inspection.
3.03 INSTALLATION Self-adhesive backing.
A. Acclimate wallcovering in the area of
installation a minimum of 24 hours before installation.
B. Examine all materials for color, quantity and quality as specified for the correct location prior to cutting.
C. Read and follow the instructions in the
manufacturer's installation sheet contained in each roll of the dry erase
wallcovering.
D. Install each strip in the same sequence
as cut from the roll.
E. Install dry erase wallcovering panels
in exact order as they are cut from bolt. Reverse hang alternate strips. Do not crease or bend the wallcovering when
handling.
F.
To allow air bubble movement and removal
of double cut waste at the seams of self-adhesive wall covering, pre-wet
surface with solution of ½ capful of mild detergent to 2 gallons clean water.
G.
Using a soft natural sponge or lint free
towel, lightly dampen the surface to be covered. Dampen seam areas more.
H.
Smooth wall covering to the hanging
surface using a wallcovering smoother, wrapped with a soft cloth, or hands using
a downward and outward motion to eliminate air bubbles, wrinkles, gaps and
overlaps.
I.
Stop installation of material that is
questionable in appearance and notify the manufacturer's representative for an
inspection.
3.04 CLEAN-UP
A.
Upon completion of installation, remove
all exposed adhesive immediately using a natural sponge and a warm, mild soap
solution and rinse thoroughly with water and dry with clean towel prior to
using.
B.
Upon completion of the work, remove
surplus materials, rubbish and debris resulting from the wallcovering
installation. Leave areas in neat clean
and orderly condition.
