SURFACE PREPARATION:
All surfaces must be clean, free of dust, chalk, oil, grease,
wax, polish, mold and mildew stains, loose and peeling
paint, rust and all other foreign substances.
New Drywall: All drywall surfaces should be suciently
sanded smooth. Remove any remaining drywall dust prior to
priming. Allow all drywall compounds to be completely dry
prior to coating.
New Wood: Remove mill glaze with sandpaper or use a
product such as BEHR PREMIUM® All-In-One Wood Cleaner
No. 63 to open the pores of the wood and follow all label
instructions. For severe stains caused by mold, mildew,
algae and fungus, apply a mildew stain removing product.
Set nails and ll holes, scratches, and gouges with the
appropriate wood ller and let dry completely. Remove all
dust with a wiping cloth. Fill all gaps with a 100% acrylic,
siliconized, paintable caulking and allow to dry completely.
Patched and lled surfaces should be sanded smooth
and dusted clean prior to coating. WARNING! Sanding or
scraping pressure treated lumber may be hazardous; wear
appropriate protection.
New Masonry: The pH must be 10 or lower prior to
coating. Smooth masonry may require an adequate prole
for adhesion. For all other smooth trowel concrete, create
an adequate prole for adhesion using a product such as
muriatic acid etcher or with mechanical means. Remove all
loose aggregate and debris. Prime with an alkali-resistant
primer.
New Plaster: New plaster should be thoroughly dried out
and cured for a minimum of 30 days before painting. When
cured, clean using a mixed solution of one part vinegar
and one part water to remove eorescence and neutralize.
Prime with an alkali-resistant primer.
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 with a rust-
inhibitive primer 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.
Shop-Primed 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.
Stain-Blocking: After priming, test for stain bleed-through
by applying the topcoat to a small section. If the stain bleeds
through the topcoat, apply a second coat of primer and
test again before top-coating the entire area. If bleeding
continues, a longer dry time of the primer prior to applying
topcoat.
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 wood ller and let dry completely. 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.
