SECTION A: Application Procedure for New Construction:
It is assumed that all wall surfaces have been made PAINT READY
prior to the installation of Viela. The Viela installer should
conduct a thorough inspection of all areas to be coated before starting
work. If wall surfaces are unsatisfactory, preparation incomplete,
or areas obstructed, it is best to deal with these inadequacies
and arrange for a cure before proceeding.
Equipment Checklist:
The Viela finish is smooth as marble and you will need a selection
of mint condition stainless steel trowels in 1", 6", 8"
and 10" depending on the surface areas you will be dealing
with. The trowel edges need to be slightly beveled to minimize edge
marks as you are applying the material. Use a stainless steel
hawk.
Surface & Area Preparation:
Wall surfaces and adjoining areas should be dry, free of dust, dirt,
grease and any other contaminates that could interfere with the
bonding characteristics, installation procedure, or aesthetic qualities
of the Viela system. All wall substrates should be prepared to a
level 5 finish for sheetrock or equivalent for other substrates.
This is the same finish requirement that would be used to finish
with gloss paints. All surfaces must be free of dust before
priming.
Masking & Bagging:
Protect all areas and surfaces not to be coated using the 3M or
an equivalent masking system. Surfaces to be masked should
be sound, clean, and free of contaminates. Be sure that any
surfaces such as doorframes, etc. that may have been painted prior
to the Viela installation, are adequately cured before masking.
See appendices for additional information.
Stain Block Primer Coat:
The stain block Primer Coat should be applied at a rate of 250 square
feet per gallon using a 3/8" nap roller or an airless with
a 517 spray tip. Allow to thoroughly dry. Lightly
sand the primer coat with 120 grit paper to remove any spurs or
rough spots.
Viela Application:
The Viela finish is a multiple coat (generally 4) application.
All the material comes pre tinted. The Viela finish is applied
at a combined rate of about 50 SF per gallon. The first coat
is applied at a rate of about 100 SF per gallon and can be applied
to a larger square footage area than the second and subsequent coats
that are applied thinner, dry faster and have a shorter working
time window. All Viela coats are applied with the hawk and
trowel using a half moon type of pattern to the application.
Keep the trowel angle low against the substrate. Apply the
material evenly to completely cover and hide the substrate.
The first coat will take approximately 6 to 8 hours to dry.
After the first coat has dried, lightly sand (200 to 300 grit paper)
any high trowel ridges. Remove any sanding dust from the substrate.
Apply the second coat of Viela to a smaller area that you can cover
in less than one hour as the material is applied at a rate of 200
sf/g and dries in one to two hours. Use the same trowel techniques
used in the first coat but apply additional pressure in order to
spread the material thinner.
Apply the third coat to an even smaller area since you will be
applying the material at a rate of 330 sf/g and the material will
dry in less than one hour. Because the third coat is applied
thinner you will need to use increasing trowel pressure to spread
the material.
Apply the fourth coat to an even smaller area since the material
will be applied at the rate of 500 sf/g and will dry in less than
1/2 hour. Again you will need to use increasing trowel pressure
to spread the material thinly.
After the fourth coat has dried for a few hours, use a clean trowel
with extra pressure to burnish the material and create sheen highlights.
Wax Application:
Apply the wax thinly to the dried Viela finish using the same trowel
and techniques that were used for the Viela material. Use
trowel pressure to work the wax into the finish and after it has
dried, buff with a lint free soft clean cloth to create extra sheen
and protection.
SECTION B: Additional Application steps for Renovation:
If you are dealing with old substrates or if you have removed wallpaper,
walls should be examined to determine the presence of mildew, wallpaper
paste, rust or other stains. If mildew is present, walls need to
be treated with bleach treatment. The bleach treatment should be
done before making wall repairs because quite often, bad areas that
might go unnoticed will show up after bleaching.
Bleach Treatment:
Using a garden type sprayer and a solution of bleach and warm water
(one-cup bleach per gallon of water), wet out the walls and allow
to dry. Immediately after spraying of bleach solution, scrub the
molded & discolored areas with a scrub brush on a pole. Scrubbing
should break up remaining mildew areas. All of the stains will not
go away, but scrubbing and wetting out with bleach will kill any
remaining live spores. Additional spraying of bleach solution and
scrubbing of stubborn areas may be necessary. Allow to thoroughly
dry.
Paste Removal:
Excess wallpaper paste must be removed by wetting out the paste
with warm water and scraping. A normal amount of wallpaper paste
residue can stay, as it will wet out, emulsify, and lock down when
the Primer Coat is applied.
Rust Block:
Check all corner beads or exposed nail and screw heads for signs
of rust and use a high quality, stain blocking metal primer (RUST-OLEUM
No. 769) on these and other areas that are likely to produce rust
in the future. Treat exposed rusty metal with Ospho prior to applying
metal primer and patching with plaster. Extremely rusted corner
beads should be removed and replaced with plastic corner beads.
Styrene Acrylic (SA) Primer Coat:
The SA primer Coat should be applied thinly at 600 square feet per
gallon using a 513-spray tip. To wet out and emulsify a moderate
amount of wallpaper paste the SA Primer Coat may be thinned 50%
with water and applied at 300 square feet per gallon. See
PASTE REMOVAL above. Allow to thoroughly dry.
Wall Repairs:
Repair or replace damaged, unsound, wet, or rotted drywall. Cut
away and/or remove any lose or delaminated wallboard paper. Patch
and finish to a level 5 finish for sheetrock or equivalent for other
substrates. Large voids, gaps or cuts need to be patched and/or
taped and mudded. Caulk where required to achieve an even &
clean line in corners and at window, doorframe, and equipment junctions.
Conduct wall repairs after applying styrene acrylic (SA) primer.
Moisture Damage:
Previous moisture problems may cause the wallboard paper to blister
or separate from the wallboard in places. Mild blistering
may not require cutting out and repairing as the paper may shrink
down and bond when the Primer Coat dries. If blistering persists,
these areas must be cut out, repaired and primed again before proceeding.
Allow to thoroughly dry. Do not proceed with Viela installation
on areas that remain wet.
Stain Block:
Apply Stain Blocker Primer at 250 square feet per gallon using a
3/8" nap roller or an airless with a 517 spray tip. Allow
to thoroughly dry. Stain Block Primer applied over walls that
have been patched & repaired will reduce flashing. Lightly
sand the primer coat with 120 grit paper to remove any spurs or
rough spots.
SECTION C: Appendices
Appendix A: Hints for Masking and Bagging the Room:
The room is assumed to be paint ready and furniture, fixtures,
and equipment free (FF&E). Check different areas in each of
the rooms for moisture levels. Make note of which areas are
checked and the moisture readings obtained at each location.
Do not continue if any moisture readings are in excess of the safe
limit for the substrate being tested. If you believe you may
have a moisture problem, stop and correct the problem before proceeding.
The return air conditioning, or hot air heat system should be turned
off or blocked before masking.
The carpet if any should be covered with polyethylene with at least
3 overlap and duct tape applied at the seams.
Dust off or wipe areas to be masked to assure masking tape sticks
to the substrate.
All heating and a/c vents should be masked, vent covers should
be removed, and thermostat should be adjusted and masked.
Sprinkler heads and smoke alarms should be masked with paper or
film at base and then use an appropriate sized Styrofoam cup to
cover the sensor. Check with building personnel to determine
whether the procedure followed meets operating codes.
All switch plate and outlet covers should be removed and placed
in room hardware bag.
All switches and outlets should be masked.
All windows, wooden trim, doors, and doorframes should be masked.
All hallways and high traffic areas should be covered with rosin
paper runners.
A clean area should be defined near the elevator allowing personnel
to remove shoes or apply clean footwear before entering the elevator
and other areas of the hotel.
Masking the doors, windows, shower units, a/c unit, mirrors or
other common sized objects encountered in each room should be done
using pre cut pieces if possible. Glue sticks are quite useful
to tack the poly material to the area being masked, and then follow
up with tape.
If the doorstops have been removed, a temporary one should be rigged
to prevent wall damage.
Be sure that any surfaces such as doorframes, etc., that may have
been painted are adequately cured.
Appendix B: Clean Up
All tools and equipment used in the application of Viela products
can be cleaned with warm soapy water.
After the final coat and the wax has dried and the room has been
inspected. The room should be cleaned up as follows.
All tape should be removed from the walls, windows, outlets, switches,
and doors. Care should be taken, as the Viela finish can be
peeled away from the wall in areas if tape is removed hastily.
When in doubt use a razor utility knife with a fresh blade to cut
the tapeline to get a clean edge. All used painting supply
material, except containers, should be removed from the room and
placed in the facilitys dumpsite. All polyethylene should
be removed from the floor unless the property owner wishes it to
stay.
Appendix C: The Inspection Process
The room should be inspected at the inception of the job to determine
if the area is in a paint ready condition.
Moisture readings are crucial since applying Viela over moist walls
will result in an unacceptable job. Work must not begin if
moisture readings are in excess of safe readings based on the wall
substrate.
Additional inspections should occur after the room is masked and
bagged.
Further inspections are necessary after the primer is applied.
Look for raised drywall face, non-dry spots, and recheck moisture
readings.
Additional inspection should take place after each coat is applied.
A final sign off inspection should occur after the room is cleaned.
Please contact TM Pratt & Company for any questions on these
instructions.
