Goo Rolling Video
1 - Choose the right roller: We suggest using a 1/4 inch nap, wool
and polyester blend roller. Choose a roller whose label indicates that it is
for smooth and gloss surfaces. We do NOT recommend using foam rollers.
Step 2 - Surface Preparation and Determination of Screen Size: Screen
Goo can be applied to any smooth paintable surface. Many materials other
than the products listed below can be used successfully. For best results
the surface should be flat and smooth. If the surface to be coated is not
smooth, it should be sanded down and wiped off prior to applying the Screen
Goo Reflective Coat. Porous surfaces such as drywall, gyproc, and wood based
materials such as plywood, particle board, MDF, should be sealed with a
flat, white latex primer prior to applying Screen Goo Reflective Coat.
Drywall surfaces should be finished to a
minimum Level 4 standard when applying our matte coatings (Reference White,
High Contrast, Max Contrast); Level 5 finish is preferable and highly
recommended. You can download a document defining levels of dry wall finish
should also be primed with a flat, white latex.
mounting your projector in its permanent location before determining the
actual screen dimensions. Once the projector is mounted you should project
an image onto your surface and adjust for image geometry. The width of the
image at the top of the screen should be the same as the width at the bottom
and likewise the sides of the image should have the same height. Finally you
should check that the image is level and square in the corners. Now you are
ready to mask off the area you will be coating with a high quality painters
tape. If you intend to create a border around your screen you should allow
an extra inch around all sides so that the coated surface will be slightly
larger than your projected image
3 - Reflective Coat: Rolling this product is a bit trickier than
rolling normal latex paint. This means that attention must be paid to
application method and roller handling. Some users report improved results
with a light sanding of the Reflective Coat; we see no disadvantage to this,
but only the Reflective Coat layers should be sanded and then only after
allowing for a minimum 24 hour drying period prior to sanding.
about 200mL of Reflective Coat in the paint tray to do your first coat. Dab
some on one side of the roller, rotate and dab some on the other. Squeeze
out any excess coating by rolling on the slanted portion of the paint tray.
Don't press too hard. Depending on your screen height, you should have
enough paint on the roller to complete approximately two adjacent vertical
Roll the coating in columns using vertical strokes covering
the full height of the screen. The coating density should be just sufficient
to cover the underlying surface. After the first column is complete, apply
the second full column, adjacent to the first, with a slight overlap between
the columns. The roller should now have very little paint left on it. You're
now ready to do your first finishing stroke. Center the roller above the
overlap, making sure the open end of the roller (which receives less
pressure) is facing the just coated side of your screen surface, so that the
overlapping layer will have a lightly feathered edge. The wire support side
of the roller mechanism naturally presses harder on the surface of the
screen, so it should be oriented to the least recently coated side of the
screen. Using just enough pressure to get the roller turning, do an
uninterrupted stroke from just above the top edge of the screen to just
below the bottom edge. It's important not to stop the roller during the
finishing stroke as this could cause marks in the finished surface.
Following the same procedure, roll two adjacent columns at a time with
finishing strokes in between until you've covered the entire viewing
surface. Allow the Reflective Coat to dry thoroughly (typically 1-1.5 hrs.)
and then repeat the above procedures for the second layer of Reflective
Even after following these
instructions to the letter, your wet surface will have a streaky appearance
and the overlaps between the columns will be clearly visible. THIS IS
NORMAL! While we realize that this is a bit counter-intuitive,
and the surface will dry to a uniform consistency and color. Resist the
temptation to go back over your work because re-rolling the coating after it
has begun to dry (about 2-3 minutes after application) will cause textural
differences, potentially resulting in permanent streaks.
before and after photos show what you can expect a correctly applied wet
surface to look like and the uniformity of the same surface after it has
dried. There's also a screen shot of an image projected on that same
Step 4 - Finish Coat: After allowing the Reflective Coat to dry,
carefully repeat the above procedures to apply two coats of Finish Coat.
Very important! The finishing strokes should be done no more than 2-3
minutes after the original paint strokes in a given area. Attempting
finishing strokes after this time period has elapsed will cause the
appearance of vertical streaks. This is the result of a difference in
texture caused by re-rolling coating which has begun to dry!
UNLIKE Reflective Coat, THE Finish Coat LAYERS MUST NOT BE SANDED OR ABRADED
UNDER ANY CIRCUMSTANCES.
5 - Ultra Black: Your Goo Kit includes a 250mL jar of Ultra Black,
a specially formulated light absorptive coating, and a foam applicator
brush. This is to permit the creation of an optional black border around
your screen. The simplest method of creating a border is to purchase pre-cut
wood trim at your local hardware store, coat it with the Ultra Black and
install it around your Goo viewing surface. If you wish to apply Ultra Black
directly to your wall, use a good quality painter's tape and mask out an
area 2-3 inches around the perimeter of the viewing area and then apply the
Ultra Black with the provided foam applicator. The Finish Coat surface must
be thoroughly dry before applying masking tape (minimum 24 hrs). After
allowing 4-6 hours for the Ultra Black to dry, slowly and carefully remove
the painter's tape covering the border.
The product can be used immediately after rolling or spraying and will look
very good after the first day, but its performance will continue to improve
for up to 3 months by which time The acrylic mixtures should be fully cured

will give you a uniform high-performance screen surface that will look
fantastic for many years to come. Sit back and enjoy, you won't believe your

Experienced spray painters will find Screen Goo quite easy to work with. If
you've never used a paint sprayer before, please consider doing a rolled
application instead. If you'd like this to be your first venture into paint
spraying, may we suggest that you take the time to familiarize yourself with
your equipment by experimenting with some less expensive coatings in
inconspicuous areas, prior to attempting your Goo masterpiece!
Suggested equipment: For
applications of less than 100 square feet we recommend using an HVLP and/or
pressurized cup spray system employing a gun with a 1.5-2mm tip diameter.
The specific type of gun is less important than the user's familiarity with
it. For larger surfaces, we recommend a piston pump-based airless spray
system with a 12 to 14 inch fan tip, no more than 50 feet of hose and a
minimum 3/4 GPM (gallon per minute) output capacity. It is very important
that none of the spray equipment be contaminated with solvent-based coatings
or cleaning agents as these will ruin the water-based Screen Goo coatings.
Reflective Coat: Screen
Goo Reflective Coats can be thinned up to 10% by volume with filtered or
distilled water prior to a sprayed application. Polypropylene Glycol-based
drying retardants, such as Screen Goo Flow Release, may also be used
according to the manufacturer's instructions for water-based acrylic
Apply two thin coats, allowing at least an hour drying
time between coats, Allow for a longer drying time in cooler or damper
conditions. The surface must be touch dry prior to re-coating
Finish Coat: Follow the
same procedure as for the Reflective Coat.

How Long Should Latex Paint Dry Between Coats?
Several factors affect the drying time of latex paint. The humidity and
temperature when the paint is applied has a significant effect. The method of
application makes a difference, as does the sheen and even paint color. The
directions on the label give you a general idea of how long latex paint needs to
dry between coats, but sometimes you need to wait longer than suggested.
Understand Drying Time and
While latex paint
usually dries to the touch within an hour (meaning
running your finger over it does not mar the paint), it can take up to a month
to cure to its final hard finish. This is because latex paint forms a dry skin
on the surface, but the underlying paint is still wet. The liquids in the paint
must completely evaporate through the dry skin to be considered cured.
Re-coating too soon can affect the
look and performance of your paint job, both in drying and curing rates.
The general recommendation for
drying time between coats is four hours for both interior and exterior latex
(water-based) paints. However, take the temperature and humidity level into
consideration. For ideal drying times, the temperature should be about 70
degrees F, with 70-percent humidity or less, and a light breeze or sufficient
air movement to help the paint liquids evaporate.
In cooler temperatures, or when
the humidity is high, allow more time between coats. Re-coating too soon can
result in an uneven sheen and very long curing times, causing doors and windows
to stick. Applying too many coats too close together can also make the paint
bubble and blister as the underlying paint liquids force their way through the
Some properties in the paint
itself affect drying time. Deep colors may take longer because of the higher
amounts of tint in the paint. Flat paint dries slower than shinier paint. Latex
dries more quickly on porous surfaces like drywall, and paint applied with a
sprayer or heavy-napped roller usually produces a heavier, slower-drying film.
When in doubt, it's wise to allow
a little extra time for the paint to dry between coats. If the humidity level is
very high, put a dehumidifier in the area to speed dying time. At humidity
levels at 90 percent or higher, the paint may never dry and will certainly never
Many primers are latex, and some
require different drying times than regular paint. Always read the label. Some
latex primers should be re-coated within 48 hours for maximum performance, while
others can be re-coated any time after the recommended drying time.
