• Reflects sun rays
• Reduces interior temperature
• Energy Star Certified for cool roofs
• Protects against moisture
• Low V.O.C., volatile organic compound, and
non-flammable
Uses:
Wh
ite-Seal™ Plus formulated to be used
without a base primer in re-coat applications
over roofs in good conditions. Recommended
for water-proofing and protecting a wide

White Seal™ Plus is an Energy Star certified
roof
coating that will provide an energy efficient
structure for many years, dramatically lowering
internal temperature, thus requiring less energy
consumption for cooling.
Make certain the roof substrate is thoroughly
clean and dry. Remove all debris and old loose
coatings by means of sandblasting or
high-pressure water blasting or wire brushing.
Any existing mildew on the surface must be
completely killed and removed prior to the
application of this product. Scrub mildewed
surface with a mixture of 1 quart of household
bleach with 3 quarts of warm water. Rinse
completely and let dry. Surface should not
accumulate water for more than 48 hours.
Coat entire roof deck with Acrylic Primer Sealer
AS-210, at a rate of 250 ft.

TECHNICAL DATA SHEET
Technical Data:
Asphalt Shingles: Roof must be clean and completely dry. Apply 2 coats of
Lanco
®
Aqua-Proof™ MD-863 at a rate of 60 sq. ft per gallon. Let dry 24
hours between coats. Be sure all tabs are completely sealed. If not, apply
Lanco
®
Siliconizer Elastomeric Crack Filler™ RC-230 and Lanco
®
High
Strength Polyester Weave MP-997 on tab joint and let dry 24 hours to
proceed.
Method of Application:
Apply with a Lanco
®
3/4" Nap Rough Surface Roller PA-568 or airless spray.
Wait 24 hours between coats. Apply only when temperature is above 50˚F
(10˚C). Do not apply if temperature is expected to drop below 50˚F (10˚C)
before the coating has completely dried. Two full coats are generally needed
for proper sealing. Always apply coats in different directions. Never thin or
dilute from full strength.
Recommended equipment: Use an airless pump with pressure of 1,500 to
2,000 psi. A fluid delivery of 1 to 2 gallons per minute with a spray tip of
0.026 to 0.035 will be adequate. Wait 24 hours between coats. The hoses
should be at least 3/8" inside diameter and of the high-pressure rate type. If
the hose length is more than fifty feet, a larger inside diameter will be
required.
Cleanup: Clean roller and equipment after use with warm soapy water.
Drying time: Approximately 60 minutes to touch. Cure time is controlled by
thickness of the applied coating, relative humidity and temperature. Allow 24
hours between coats.
Limited warranty: The manufacturers liability in connection with the sale of
this product extends only to the replacement price if it should fail to comply
with quality standards or specifications. Protect from freezing.
Warning!: Do not allow product to freeze. Do not store in temperatures
