INTERIOR/EXTERIOR BONDING PRIMER
NO. 432
Aluminum: Remove all oil and grease from the surface with
a solvent in accordance with SSPC-SP1. Prime the area the
same day as cleaned.
Previously Painted Surfaces: Remove all loose and
peeling paint and all other foreign substances. Clean any dirt
and grease by scrubbing the surface with a detergent and
water solution, followed by a thorough rinsing with clean
water. Set nails and ll holes, scratches, and gouges with the
appropriate patching material. Let dry completely and sand
smooth. Remove all dust with a tack or wiping cloth. Fill all
gaps with a 100% acrylic, siliconized, paintable caulking,
and allow to completely dry prior to coating.
IMPORTANT NOTE: While BEHR® Interior/Exterior Bonding
Primer is formulated to bond without sanding, it is
recommended that a small area be tested for adhesion prior
to beginning the job.
BEHR Interior/Exterior Bonding Primer is not designed to
reattach loose, aking or peeling paint. Such conditions
must be corrected prior to applying this primer.
Applying BEHR Interior/Exterior Bonding Primer to glass will
block out light. Dark colors absorb more heat than lighter
colors. This added heat causes thermal stress which may
aect the glass and can cause it to break.
Due to the diverse composition of plastic substrates, always
test a small area for acceptable adhesion. Many types
of highly engineered plastics present a challenge with
adhesion. Please contact your Behr representative for proper
recommendations.
Do not use solvents that contain hydrocarbon such as
mineral spirits because they can leave an oily residue. Use a
water-based cleaner/degreaser for cleaning the surface
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, nd out how to
protect yourself and your family by contacting the National
