PRODUCT INFORMATION
BEHR® Interior/Exterior Metal Primer is a rust-inhibitive primer that can be applied over clean and sound rusty metal surfaces
while preventing corrosion with minimal surface preparation. This innovative water-based primer features fast dry time,
low odor and easy clean-up.
RECOMMENDED USES:
Ideal for use on properly prepared coated/uncoated ferrous and non-ferrous metal surfaces such as: Doors, Windows, Trim,
Shutters, Fences, Garage Doors, Outdoor Furniture, Railing and Wrought Iron.
PRODUCT SPECIFICATIONS:
Tint Bases/Max Tint Load:
No. 435 126 oz / 4 oz
Resin Type: Acrylic Modied Epoxy
Weight per Gallon: 10.5 lbs
% Solids by Volume: 41% +/- 2%
% Solids by Weight: 53% +/- 2%
VOC: < 100 g/L
Flash Point: N/A
Viscosity: 105 KU
Recommended Film Thickness:
Wet: 4.5 mils / Dry: 1.9 mils @ 350 sq ft/gal
Wet: 3.6 mils / Dry: 1.5 mils @ 450 sq ft/gal
Note: A minimum dry lm thickness of 1.5 mils is
required on sound ferrous metal surfaces for adequate
corrosion resistance. Additional lm build may be
necessary depending on surface and/or exposure
conditions. For severe exposure conditions, such as
marine environment, apply two coats (1.5 mils per coat)
of BEHR INTERIOR/EXTERIOR METAL PRIMER for optimal
corrosion protection.
Coverage: 350 - 450 sq ft/gal depending on the surface
texture, porosity and application method. Does not include
the loss of material from spraying.
APPLICATION:
Brush: High quality nylon/polyester brush
Roller: 1/4" - 3/8" nap
Airless Spray: Fluid pressure of 2000 - 2800 psi
Tip: .011”-.017”
Filter: 60 mesh
Thinning: This primer is designed to be applied at package
consistency under normal environmental and application
conditions. If necessary to maintain good workability,
add up to 1/2 pint (8 oz) of clean water per gallon.
NOTE: Overthinning may result in insucient lm thickness
and subsequent pinpoint rusting.
Dry Time: @ 77°F, 50% RH
Longer dry time required in cooler temperatures and in
higher humidity.
To Touch: 30 minutes
To Recoat: 1 hour
SURFACE PREPARATION:
It is recommended to start priming on the same day the
surface is cleaned and prepared. All surfaces must be sound,
clean, dry, free of dust, chalk, oil, grease, wax, polish,
mold and mildew, loose peeling paint, loose rust and dust
particles and all other foreign substances. In some cases,
scraping or sanding may be needed to allow the primer
to adhere. Do not use if surface is structurally unsound or
severely deteriorated. If washing is necessary, use a
non-soapy detergent or a TSP substitute, rinse well
and allow to dry.
STEEL: Minimum surface preparation is Hand Tool Cleaning
in accordance with SSPC-SP2. Remove all oil and grease from
the surface with a solvent in accordance with SSPC-SP1.
For optimal performance, use Commercial Blast Cleaning
in accordance with SSPC-SP6. Prime the area the same day
as cleaned.
GALVANIZED STEEL: Solvent clean new galvanized metal
in accordance with SSPC-SP1 to remove oil and grease from
the surface. Pre-treat with a phosphoric acid solution or
a commercially-available etching solution. Galvanized
metal that has been passivated with chromates or silicates
may require brush blasting in accordance with SSPC-SP16
to remove these treatments. Rusty galvanizing requires a
minimum of Hand Tool Cleaning in accordance with
SSPC-SP2. Prime the area the same day as cleaned.
STAINLESS STEEL: Mechanically abrade the entire surface
using a scouring pad or wet and dry sandpaper (do not use
steel wool). Clean the surface to remove all residue. Prime
the areas the same day as cleaned.
SHOPPRIMED STEEL: As there is potential for many forms
of contamination during storage and transport, a thorough
cleaning is always recommended for shop-primed surfaces.
Paint exposed areas, i.e., where shop primer is abraded,
with the same material as used for shop priming to comply
with SSPC-PA 1 for touching up shop-primed surfaces.
Note: Assess the integrity of the shop primer prior to
application of subsequent coatings. Review all coatings
intended for the project and conrm the compatibility
between shop and eld-applied coatings.
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.
COPPER AND BRASS: Remove oil, grease, dirt and other
surface contaminants by Hand Tool Cleaning in accordance
with SSPC-SP2. Prime the areas the same day as cleaned.
Glossy Surfaces: For maximum adhesion, sand the surface
thoroughly before coating.
Fire Restoration: Not recommended. Primer
recommendations: KILZ® RESTORATION, KILZ ORIGINAL
INTERIOR, KILZ ORIGINAL EXTERIOR or KILZ ORIGINAL
LOW ODOR Primers.
WARNING! If you scrape, sand or remove old paint, you may
release lead dust. LEAD IS TOXIC. Contact the National Lead
Information Center at 1-800-424-LEAD or visit
