RV/Mobile Home Roof Silicone Coating is a
high solids, 100% silicone based roof coating that creates a
durable, breathable, watertight and weatherproof barrier that
resists natural weathering and reflects heat from the sun.
RV/Mobile Home Roof Silicone Coating resists ultraviolet
radiation and adapts to temperature extremes to provide
long-term weathering protection and energy savings. The
premium high solids formula allows for one coat application.
RV/Mobile Home Roof Silicone Coating can be applied to
RV’S, Mobile Homes, Campers, Trailers, Gutters, and
Sheds. RV/Mobile Home Roof Silicone Coating contains no
solvents.

PRODUCT APPLICATION
SURFACE PREPARATION
All surfaces must be clean and free from dirt, grease, oil,
mold, algae, loose granules, loose paint, rust, excess chalk,
and other foreign matter which could prevent proper
adhesion. Use a high pressure wash and stiff bristle brush or
broom to scrub surface. Rust-Oleum One Step Roof Prep or
an appropriate non-filming cleaner should be used to remove
all grease or oily deposits. EPDM roofs may require
aggressive power washing and need to be cleaned twice to
remove all surface contamination. Rinse thoroughly and
allow to dry. Seams, fasteners, roof penetrations, and any
roof defects should be repaired and sealed prior to applying
the topcoat.
For EPDM, PVC, TPO AND HYPALON roofs, it is
recommended that the roof be primed with Rust-Oleum 105
Single Ply Adhesion Primer*.
SPRAY EQUIPMENT RECOMMENDATION
Minimum spray equipment requirements are a 7000 psi unit
delivering at a capacity of 1-2 gallons per minute with a
.027-.040 tip (.027-.031 preferred). 1.0" lines on the sprayer,
3/4" whip to gun.
* See primer label and technical data sheet for correct
surface preparation and application procedures.
PRODUCT APPLICATION (cont.)
APPLICATION
Do not thin or alter product. Apply when temperatures are
between 32-120°F. For cold weather application (below 55°F),
store unopened container indoors for 24 hours prior to
application. Do not apply if rain is expected in less than 5
hours. Mechanically mix prior to application and during use.
Avoid entraining air when mixing. Apply with brush, ¾” nap
roller, or spray equipment. For one coat application: Apply at
a minimum rate of 1 gallon per 100 square feet (16 wet mils).
Coating must be applied uniformly and without pin holes.
This product cures through absorption of moisture from both
the substrate and the air. Cure time will be faster in humid
conditions and on substrates that hold moisture such as
concrete. Keep containers closed as much as possible during
use. Open and partially full containers will skin over quickly. If
this occurs, remove the skins and continue using the
remaining product. Avoid walking on RV/Mobile Home Roof
Silicone Coating except for occasional maintenance. Use
caution when walking on a wet roof.
COVERAGE
One gallon will cover 100 square feet at 16 wet mils in a
single coat application.
DRY & RECOAT TIMES
Dry and recoat times are based on 70ºF and 50% relative
humidity. Dries in 2 to 4 hours. Return to service after 24
hours. Environmental or site specific conditions may require
variations in cure times.
LIMITATIONS
The application of Rust-Oleum roof coatings assumes
substrate to be coated is structurally sound and has
reasonable life expectancy prior to being coated. Not for
application over shingles.
