PRODUCT APPLICATION
SURFACE PREPARATION
All surfaces must be clean, dry, sound and free from dirt, grease, oil,
mold, algae, loose granules, loose gravel, loose paint, rust, excess chalk and
other foreign matter which
could prevent proper adhesion. Rusted areas must be primed with Rust-Oleum
Universal Roof Primer or a similar product. Surface temperatures should be
under 100ºF (38ºC) to avoid premature curing. If the roof surface is hot,
apply a light water spray to reduce the surface temperature.
WARNING! If you scrape, sand or remove old paint, you may release lead
dust. LEAD IS TOXIC. EXPOSURE TO LEAD DUST CAN CAUSE SERIOUS ILLNESS, SUCH AS
BRAIN DAMAGE, ESPECIALLY IN CHILDREN. PREGNANT WOMEN SHOULD ALSO AVOID
EXPOSURE. Wear a NIOSH-Approved respirator to control lead exposure. Clean up
carefully with a HEPA vacuum and a wet mop. Before you start, find out how to
protect yourself and your family by contacting the National Lead Information
Hotline at 1-800424-LEAD or log on to
www.epa.gov/lead.
