Interior
Waterborne Urethane Topcoat
Features & Uses
Awlgrip's
laboratories have developed a waterborne urethane for interior
applications in engine rooms and other areas where a durable
urethane is required and the application of a solvent borne coating
is impractical. This two component urethane has excellent solvent
resistance to denatured alcohol and acetone as well as diesel fuel
and anti-freeze. Gloss retention and heat resistance to 180° F. are
excellent. Unlike most water based urethanes, Awlgrip's coating is
shelf stable and has excellent hiding characteristics. This product
is available in Awlgrip's most popular white colors and can be
applied by spray, brush, or roller.

Gray (WT1200)
Packaging: Available in 1 Gallon Kit
Only
Theoretical Coverage - Sq. Feet/Gallon
Spray Application:
725 Sq. Feet at 1 mil dry film thickness; 363 Sq. Feet at 2 mils
dry, 241 Sq. Feet at 3 mils dry.
Recommended Wet Film Thickness:
4.5-7 mils (112.5-175 microns), total of 2-3 coats.
Recommended
Dry Film Thickness: 2-3 mils (50-75 microns), total of 2-3
coats.
Coverage calculations are calculated for mixed base and
converter, reduced 25% and are based on a theoretical transfer
efficiency of 100%. Actual coverage rate obtained will vary
according to equipment choice, application techniques, part size,
and application environment.
Anticipated Cure Time at 77°F/50%
R.H: 18 hours to tape free; 3 days to light service; 7 days for full
cure.
Brush/Roller Application: 725 Sq. Feet at 1 mil dry; 363
Sq. Feet at 2 mils dry, 241 Sq. Feet at 3 mils dry .
Recommended
Wet Film Thickness: 4.5-7 mils (112.5-175 microns), total of 2-3
coats. Do not exceed.
Recommended Dry Film Thickness: 2-3 mils
(50-75 microns), total of 2-3 coats. Do not
exceed.
Recoatability: Spray applications consist of two to three
coats applied over 1-4 hours. Exact time will vary with temperature,
project size, and film thickness applied. Brush/Roller applications
require at least 2 coats applied a minimum of 16 hours apart.
Awlgrip topcoats which have been allowed to cure more than 24 hours
must be sanded before recoating.

Surface Preparation
A clean, dry
surface is essential to the success of any coatings application.
Remember - Clean before sanding. Sanding often melts greases and
oils into the surface making it difficult to obtain a clean surface.
Refer to Awlgrip's 12th Edition Application Guide (www.uspaint.com)
for additional information regarding surface cleaning products and
procedures.
Awlgrip products
should be applied over properly prepared 545 Primer in spray
applications, or AWL-QUIK® Primer in brush/roller
applications.
Mixing
& Reduction
Spray:
Mix by volume three parts Awlgrip Interior Water Based Topcoat Base
Component with one part Converter to a smooth, homogenous mixture.
Reduce up to 25% with T0149. Overall mix is 3:1:1 by volume.
Example: 9 oz. Base, 3 oz. Converter, 3 oz. T0149. Painting in high
temperature conditions may require additional reduction. 40%
reduction is the maximum recommendation.
Brush/Roller: Mix by volume three parts Awlgrip
Interior Water Based Topcoat Base Component with one part Converter
to a smooth, homogenous mixture. Reduce 15-25% with T0149. Overall
mix is 3:1:¾ or 1 by volume. Example: 9 oz. Base, 3 oz. Converter,
2-3 oz. T0149. Painting in high temperature conditions may require
additional reduction. 40% reduction is the maximum recommendation.
At 15% reduction the material brushes fine, but spray application
has excessive orange peel.
Application Instructions
General: The
primed surface must be clean and dry. Achieving maximum gloss and
distinction of image requires the primer be smooth sanded with
220-320 grit paper before topcoat application. Using a contrasting
mist coat of lacquer primer as a "guide coat" is recommended. Smooth
sanding until all the "guide coat" is removed indicates a texture
free surface.
Two to three
coats are recommended for spray applications. Brush/Roller
applications require two to three coats. Regardless of application
method two coats is the minimum! Topcoating cannot be done in one
coat!
Spray
Application: Apply a light, smooth, slightly wet tack coat to
the surface. Allow tack coat to "flash off" 5 to 10 minutes. Then
apply a full, wet coat to achieve color coverage (i.e., hide) and
film thickness requirements. If preferred, three coats may be used.
Allow the second coat to "flash off" 5 to 10 minutes until only
slightly tacky before applying third coat. In three coat
applications, coats two and three are not "full, wet" coats. The
second coat is a slightly heavy tack coat with the third coat just
wet enough to obtain full hide (opacity) or color
coverage.
Brush/Roller
Application: Apply Awlgrip Topcoat in two to three coats of 1.5
to 2.5 mils WFT each. Allow 4-16 hours between each coat. Sanding
between coats with 280 to 400 grit paper will provide a smoother
finish.
On large
interior surfaces first roll the Awlgrip Topcoat and then smooth the
roller stipple by lightly tipping the surface with a brush. This can
be done with 2 painters working side by side (i.e., 1 rolling and 1
tipping), or with 1 painter rolling approximately 6 square feet and
then tipping that area before rolling any further.
Do not apply
paint materials to surfaces warmer than 105°F or colder than 55°F.
Do not attempt to cure products at temperatures below 55°F. Pot Life
5 hours.
IMPORTANT
Before
mixing, read Material Safety Data Sheet for health hazard and safety
information.
