DESCRIPTION: Snow-Coat
roof coating is an acrylic polymer elastomeric roof coating.
A top grade coating designed for maximum protection against
sun and weather. The reflective value of this product
helps to reduce interior temperature and protects the
roof and roofing membrane by reducing heat absorption,
asphalt oxidation and rapid thermal dimensional changes.
It also decreases the chance of excessive loads placed
on cooling equipment.
USES: Snow-Coat roof
coating is a top grade product formulated to have exceptional
resistance to mildew and fungus growth. Used to provide
a durable, water resistant, decorative and energy saving
finish for most sound roof surfaces. May be used over
de-greased or weathered concrete, cured cold applied asphalt
coatings, smooth surface roofings, most prepared mineral
surfaced roofings and hot-mopped built-up roofing.
SURFACE PREPARATION:
A clean surface is absolutely essential for proper adhesion
of this material. All dirt and unsound accumulations must
be removed. Use a good quality chlorinated compound to
remove any mildew or algae which may be present. Rinse
with water. Where necessary, use brooming and high pressure
water hosing to clean the base surface. Allow water to
completely dry before proceeding. Roof substrate must
drain within 48 hours. (1)Built-up Roofing: Must be 1
month old or more. Clean and prime first with 1 gallon
per 100 square feet primer and allow to dry before application
of finished white surfacing. (2)Granule Surface: Must
be clean, sound surface with no loose or foreign material.
(3)Metal Roofs: It is important to wire brush and remove
rust areas and prime with rust inhibiting primer. All
fasteners must be tightly secured or replaced and encapsulated
with Elastomeric Caulk. All roof seams and flashings must
be covered with Elastomeric Caulk and membrane reinforcement.
(4)Polyurethane Foam Roofs: Apply directly over new or
existing white coating.
APPLICATION: Stir
in container until uniform in color and consistency. For
Brushing: Use a soft nylon bristle broom or brush and
apply with long even strokes. Avoid over-brushing. Do
not attempt to retouch while film is drying. Wait until
cured before applying 2nd coat. For Roller: Medium to
long nap for textured or rough surfaces. For Spray: Airless
spray system with a minimum working pressure of 3000 PSI.
Coverage rates will vary depending on porosity of surface
as well as roof pitch. One coat can suffice. However,
two coats are recommended for maximum reflectivity, durability
and life cycles. Recommended Coverage Rates: (1)Mineral
Surfaced Roll Roofing - 3 gal/ 100sq. ft.; (2)Metal Roofing
- 1 to 2 gal/100sq. ft.; (3)Concrete Tile or Smooth Roll
Roofing - 1.5 to 2 gal/100sq. ft. Recommended application
is two coats (1/2 of above coverages for each coat) applied
at right angles to previous coat by brush, roller or spray.
First coat must dry before second coat is applied. During
application, keep tools clean and free from coating build
up by rinsing frequently with water. Do not apply over
uncured cold applied asphalt coating, wooden shingles,
shakes, flood coats of hot melt asphalt or coal tar, or
bare or rusted steel. Asphalt must be dull, not glossy.
Do not apply unless temperature is 50°F and rising.
Do not apply when rain or frost is forecast within 24
hours after application. Conditions of high humidity will
prevent curing in the usual four hours. Avoid heavy foot
traffic.
KEEP PRODUCT FROM FREEZING
CLEAN-UP: Clean brushes,
tools and other equipment with soapy water immediately
after use. Dried film may require paint remover.
