Basic Installation Steps:
|
|
|
1. Remove existing paper. Painted surfaces should be washed. Extremely porous
surfaces should be pre-sized. Fill large cracks or holes with spackle or filler.
Use waterproof spackle and paste for walls where moisture or humidity is likely. |
|
2. Using a level or plumb bob, make a vertical guideline on the wall for
proper placement the first length. Brush or roll paste over wall surface to be
covered by the first two or three sections (if using waterproof paste, reduce area
somewhat.) One gallon covers approximately 15 sq. yards.
|
| |
|
|
3. Hang the first length. Work from center of strip towards edges to remove lumps and bubbles. |
|
4. Hang the second length in the same manner. Glass textile wallcovering can be
butt joined or double cut, if preferred.
|
| |
|
|
5. Repeat until completed. Trim top and bottom edges in and around electrical outlets,
etc., according to standard procedures. Material softens with moisture, so work
quickly.
|
|
6. Allow installed glass textile wallcovering material to dry thoroughly at room temperature
prior to painting. Apply primer and finish paint in accordance with manufacturer
recommendations and job specifications.

Product and Installation Information:
Glass textile wallcovering is made
from all natural, glass fiber yarns that are woven into
various textures and patterns that vary in thickness.
The glass weave material is treated with a natural binder to provide dimensional stability during installation. It is installed by a dry hang method or some patterns can be pulled through a paste machine. The unprimed patterns require a latex primer coat of paint and then
a final finish coat of paint. The pre-primed patterns may require only one finish coat of paint when using a low luster/satin finish.
No special installation tools are
required, however never use a seam roller. We highly recommend
using top quality commercial adhesive, primer, and paint
products for the best results.
For a highly breathable surface,
latex paints and finishes are recommend. For a highly
durable surface, epoxy finishes can be used. For a totally
sealed surface use alkyd paints. Elastomeric coatings
can also be used.
Substrate Preparation:
1. Surface Fixtures: Remove switchplates, wall
plates, and surface-mounted fixtures in areas where wallcovering
is to be applied.
2. Cleaning: Clean substrates to be free of
dust, dirt, stains, oily coatings, water-based paint, or other compounds
preventing adhesive bond or impairing performance of installed materials.
a. Mildew: Remove mildew and treat wall surfaces
with mildew growth inhibitor recommended by manufacturer. In high
humidity areas, an antimicrobial is recommended to be added to adhesive,
primer paint and finish paint for added protection if not already
added by manufacturer.
3. Moisture Content: Test substrate with electronic
moisture meter to verify that surfaces to be covered do not exceed
a moisture content of 5%.
4. Stains: Do not install wallcoverings over
oil-based wood stains or felt-tip pen markings without proper substrate
preparation.
5. New Plaster: New plaster must age at least
30 days before hanging wallcovering. Surface must be smooth and free
from surface chalk. It should not have more than 5% moisture
content.
6. New Drywall: New drywall must be wiped down
with a damp cloth to remove sanding dust. All nails and screws and
joint depressions must be taped and spackled to a smooth finish.
Non-rust proof nails and screws must be sealed to prevent bleed-through.
It should not have more than 5% moisture content.
7. Other Porous Surfaces: Walls must be clean,
dry, smooth and structurally sound. Use an all purpose cleaner to
remove dirt, grease, and wax. If a painted surface is found to be
unsound, the paint will have to be removed. Repair all cracks and
holes.
8. Non-Porous Surfaces: Plastic, glass, Formica,
ceramic tile, baked enamel, paneling, cement block, or glossy paint
etc. should be primed with an appropriate primer specially formulated
for difficult-to-bond surfaces to maximize the initial tack and final
bond strength of the wallcovering adhesive. If a painted surface
is found to be unsound, the paint will have to be removed. Repair
all cracks and holes, and fill in mortar joints with low shrinking
joint compound and prime surface. All surfaces should be rendered
free of joints, cracks, holes rough edges, etc., to offer a smooth
surface.
9. Renovation of other wallcoverings: Removal
of old wallpaper or vinyl is recommended to prevent bleedthrough
and/or delamination. Check wall surface after removal to determine
that walls are structurally sound, clean and dry. Surface should
be free of holes. rough edges, etc. that could affect the quality
of the installation.
10. Old plaster: Check carefully for the possibility
of delamination that con occur with old walls in poor condition.
Remove questionable plaster and replaster to smooth finish. Sand
lightly and check moisture content as with new plaster.
11. Substrate Priming: Verify that substrates
are thoroughly dry. Prime and seal substrates as necessary in accordance
with adhesive manufacturers recommendations.
Installation of Glass Textile Wallcovering
1. Material Inspection: inspect each roll of
glass textile wallcovering material, verify that pattern matches
approved samples, and inspect for defects before cutting.
2. Glass Textile Wallcovering: Using
a dry hang method, place panels consecutively in the
order cut from rolls, including filling spaces above
or below openings. (Do
not reverse sides, use same side always). Lengths may
be precut.
a. Substrates: Verify that primed substrates are
fully dry prior to application of adhesive and installation of wallcovering
b. Adhesive: Apply adhesive evenly to substrate
with 3/4" nap roller, spray, or brush, with no gaps or bare
spots. Do not apply more adhesive in each application than will be
covered by one or two lengths of glass textile wallcovering, to prevent
dry spots and insufficient adhesion.
3. Application of Wallcovering: Apply glass
textile wallcovering to the adhesive covered substrate.
a. Set the first wallcovering panel. Ensure that
the panel is plumb. Eliminate air pockets and secure wallcovering
to wall surface with plastic smoother applicator. Work from center of strip
toward edges. Do not overwork material.
b. Seams: Butt join sections and match pattern
of texture at eye level between panels and across seams of wallcovering
materials to assure tight straight closure. Do
not use a seam roller. Patterns may
be double cut where edges appear rough or bolt has been damaged to
assure tight, straight closure. Horizontal seams are not acceptable
unless otherwise specified.
c. Remove excess adhesive along finished seam immediately
after each wallcovering strip is applied. Use damp but not wet sponge
and use caution not to remove primer from the pre-primed material.
Avoid getting adhesive on face of wallcovering.
d. Corners: Allow glass textile wallcovering
to set momentarily on adhesive to ensure maximum flexibility
and positive molding characteristics. Using a damp sponge
(being careful not to remove the primer from the pre-primed
material by overworking/rubbing), turn and wrap to form
corners which are crisp, square, and true, and with
wallcovering fully adhered to substrate. Wrap wallcovering
a minimum of 2 inches beyond outside corners. Double
cut wallcovering at inside corner to assure corrections
in corners that are not plumb.
4. Bonding: Install wallcovering with sound
bond of material to substrate.
5. Trimming: When possible, install material
prior to installation of plumbing, fixtures, trim, cabinets, etc.
Trim wallcovering evenly to edges of wall penetrations, outlet boxes,
reveals, adjacent door or window frames, and moldings. Trim seams
and other straight cuts using a straight edge. Perform cutting work
on a cutting table when possible. When wall cutting procedures are
required, perform cutting without scoring, perforating, or otherwise
damaging the substrate. Use a fresh blade for each cut.
6. Appearance before Painting: Wallcovering
to be smooth, clean and free of wrinkles, gaps, overlaps, and other
defects. Raising and puckering at seams, bubbles, blisters, telegraphing
of adhesive spreader marks, and other surface imperfections are not
acceptable. Cuts or edges of wallcovering visible around cover plates
or trim are not acceptable. Redo or replace defective installation.
Painting and Finishing for Un-Primed or Pre-Primed System
Paint Selection:
A high quality paint coating is recommended. Consult with your
favorite paint supplier. For certain applications, we recommend the
following:
- For environmentally friendly/green system, use a no VOC paint.
- For mold and mildew protection, use Zinsser
Perma White paint.
- For high traffic areas, use water-based epoxy paint.
1. Allow installed glass textile wallcovering
material to dry thoroughly at room temperature prior to priming and/or
painting.
2. For Un-Primed Patterns
a. Priming and Painting: Apply one coat of latex
primer with 3/4" to 1" roller nap to cover material thoroughly
without gaps or bare spots, and allow to dry. If primer is sprayed
on, it must be back rolled to work it into the wallcovering. After
primer is dry, apply one coat of finish paint to produce uniform final color or
even coverage, thickness and intensity.
3. For Pre-Primed Patterns
a. Painting: Apply one coat of finish paint with
3/4" to 1" roller nap cover and backroll to cover material
thoroughly without gaps or bare spots to produce uniform final color
of even coverage, thickness, and intensity, If finish coat is sprayed
on, it must be back rolled to work it into the wallcovering thoroughly
without gaps or bare spots to produce uniform final color of even
coverage, thickness, and intensity. See Technical Data Sheet for paint consumption.
4. Replacement: Upon completion of wallcovering
installation in each space or area, reinstall items, such as fixtures,
plates, and similar items, which had been removed, using workmen
skilled in the trades involved. Verify that cut edges of wallcovering
are concealed.
5. Finished Appearance: Finished
wallcovering to be smooth, clean, of uniform color, finish, and appearance,
and free of wrinkles, gaps, overlaps, bare spots, holidays, roller
marks, uncoated areas, and other defects. Redo or replace defective
installation.
Cleaning and Protection
1. Cleaning of Adjacent Surfaces: Promptly remove
all sealers, primers, adhesives, and other materials which are spilled,
splashed, or otherwise fall on adjacent surfaces, in a manner not
to damage or discolor the surface from which it is removed.
2. Final Cleanup: Remove surplus materials,
rubbish, and debris resulting from wallcovering installation upon
completion of work. Leave areas of installation in neat, clean condition.

Adhesives, Primers
and Paints
Good, professional quality adhesive, primer, and paint should always
be used for best results. No special brands are required for a glass textile wallcovering
installation. The installer should use appropriate adhesives, substrate
primers, and paint necessary or specified to achieve a proper installation.
Reversing Patterns
Both sides of all glass textile wallcovering patterns can be used as the front,
or surface side, but make sure the same side is used as the front throughout
the installation. If reversed at random, the pattern or texture may
have a slightly different appearance when painted.
Lead Base Paint Encapsulation or
Enclosure
Glass textile wallcovering is not an encapsulant.
However, it can be used as a reinforced fiber type material
along with an approved encapsulant coating system or paint.
It also offers a decorative element in the encapsulation
process as most coatings are smooth and do not have a
decorative finish feature.
Mechanical or chemical removal lead base paint processes
can often weaken a plaster surface. Glass textile wallcovering
is ideal to reinforce the substrate before painting. The
surface must be replastered to a smooth finish and an
appropriate primer applied before installing glass textile
wallcovering.
Seams
Do not use a seam roller on glass textile wallcovering
seams. Avoid overworking glass textile wallcovering when wet, because
the texture will be pressed flat to the wall resulting in
a dull or off color finish when painted.
Corners
Use a damp (not wet) sponge to soften glass textile wallcovering
at outside corners and similar spots to make it more pliable
and easier to mold or turn to prevent breaking yarns.
Inside corners are best made by double cutting at the
corner. This will allow corrections at corners that are
not plumb. Outside corners are installed in a similar
manner, only proceed past corner a minimum of 2 inches
before cutting.
Glass textile wallcovering can also be cut directly along
the edge of a corner if necessary however, there will
be a reduction in protection of the substrate at the edge
where integrity of the glass textile wallcovering has
been interrupted. For maximum strength at corners, it
is always recommended to turn the corner with a continuous
wrap of glass textile wallcovering as described in the above paragraph.
Corner guards are highly recommended for all high traffic
corners.
Tools & Equipment
A plastic applicator or rubber roller is recommended to
be used to secure glass textile wallcovering to the substrate.
Tips
When hanging glass textile wallcovering over walls which
have contrasting light and dark areas, it may be necessary
to prime the surface with a pigmented, pre-wallcovering primer.
Quality Assurance
Glass textile wallcovering is a woven fabric and some irregularities
may occur. Each bolt of glass textile wallcovering is visually inspected
at the factory and irregularities, if observed, are marked
at the edge of the bolt with a small tab. Approximately
3 feet of material is added to the bolt for each tab.
Every bolt should be inspected by the installer prior
to cutting and installing.

& MAINTENANCE INSTRUCTIONS |

Repairs
Minor scratches and scrapes: Where fibers are raised,
sand tightly and touch up with a paint brush or roller.
Deeper cuts: Some cuts may only require adding a thin
stream of latex caulk applied and then smoothed with
the finger. A light sanding before the caulk is applied
may be required to smooth away any raised fibers. After
the caulk is dry, simply touch up with paint.
Penetration through substrate: Cut a piece of glass
textile wallcovering approximately 3-4 inches all around
larger than the damaged area. Place the patch over the
damaged area, match the lines and pattern, tape in place.
Using a double cut technique with a sharp straight edge,
cut through the patch and the existing glass textile
wallcovering on the wall through to the adhesive following
the design of the pattern and texture. Be careful not
to cut through to the paper on the sheetrock.
Remove the patch end tape to the wall next to the damaged
area to assure not losing or turning the patch in the
wrong direction when applying. Remove the old glass
textile wallcovering and repair or replace the damaged
substrate area so that the new patch will evenly match
the height of the existing wallcovering. To assure removal
of damaged area without removing the paper from the
sheetrock, make a cross cut from corner to corner to
remove the wallcovering and start from the center removing
in smaller pieces.
If needed, prime the substrate. Apply adhesive with
brush or roller depending on size of repaired area.
Install the glass textile wallcovering patch exactly
in same position as it was cut out and smooth lightly
using a rubber roller or plastic applicator to ensure
installation without air bubbles.
Note: Do not use a seam roller as it will
distort the texture in the wallcovering.
Allow to dry thoroughly before applying latex primer
coat. When primer coat is dry, if seams are visible
or raised fiber nap, a light sanding with a 100 grit
paper is recommended and apply a thin stream of latex
paint caulk in the cut areas to fill in. Feather out
the caulk evenly to provide a seamless appearance. Once
dry, apply topcoat paint to match existing paint.
Tips during and after installation
If after priming you find bubbles, inject adhesive with
a needle or make vertical cut and insert adhesive with
paint brush. Smooth down the wallcovering with rubber
roller or plastic applicator and let sit. Wipe off excess
glue with damp sponge.
Popcorn ceiling: Caulk edge between wallcovering and
ceiling and around windows and area where condensation
and wetness occurs.
Cleaning and Maintenance
The type of paint finish will determine the cleaning
solution. A latex enamel or epoxy paint can be cleaned
and disinfected. A brush can be used on heavier soiled
areas. Flat paint does not typically hold up to much
washing, and may require touchup or repainting of the
surface.
In high humidity climates where mold and mildew are
a problem, it is recommended to not use a biodegradable
room freshener as it is food for mold and mildew spores
to grow and can cause surface mildew.
Corner guards are recommended for corners in high traffic
areas for added protection and longer life for walls.

| ESTIMATING GUIDE |
back to top |
To determine how much glass textile wallcovering to order, first determine the amount of square footage to be covered.
Multiply length x height = sq.ft.
Example: Wall is 15 feet wide x 9 feet high = 135 sq.ft.
One lineal yard of 39" wide material contains 9.75 sq.ft.
Then divide the amount of sq.ft. by 9.75 to determine the number of yards to order.
Example: 135 sq.ft. divided by 9.75 = 13.8 yards (best to round up to next number)
Waste is minimal with glass textile wallcovering. Allow approximate 5 percent more than the formula indicates.
For your use in comparing the sq.ft. amount and cost per sq.ft. from one product to another and, the chart below shows the number of sq.ft. per lineal yard of various width materials.
To compare 54" wide vinyl wallcovering to 39" wide glass textile wallcovering, divide the cost per yard of the 54" wide by 13.50 and the cost per yard of the 39" wide GTW by 9.75, and you can use the cost per sq.ft. in price comparison.
For example, if an average cost of a Type II 54" vinyl is $15.00 per yard, the cost per sq.ft. would be $15.00 divided by 13.50 = $1.11; if an average cost of 39" GTW is $5.00 per yard, the cost per sq.ft. would be $.51 per sq.ft.
