DESCRIPTION: Tuff-Coat
roof coating is an acrylic polymer elastomeric roof coating.
A PREMIUM 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: Tuff-Coat roof
coating is specially designed to provide a tough weather
resistant and decorative finish for most sound roof surfaces.
May be used over de-greased or weathered aluminum, galvanized
steel, primed steel, treated unweathered or weathered
concrete. This product can also be used on cured cold
applied asphalt coatings, smooth surface roofings, most
prepared mineral surfaced roofings.
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. There cannot be any standing water.
Smooth-Surface Roofing: Must be 6 months old or
more. Clean and prime first with 1 gallon per 100 square
feet Elastomeric Emulsion and allow to dry before application
of finished white or tinted surfacing. Granule Surface:
Must be clean, sound surface with no loose or foreign
material. Best results can be achieved if surface is slightly
dampened or fogged before coating. 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.
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 second 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/ 100 sq. ft.;
(2) Metal Roofing - 1 to 2 gal/100 sq. ft.; (3)Concrete
Tile or Smooth Roll Roofing - 1.5 to 2 gal/100 sq. 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.
CLEAN-UP: Clean brushes,
tools and other equipment with soapy water immediately
after use. Dried film may require paint remover.
