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 suciently
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.
Weathered Wood Surfaces: To remove loose wood
bers, latex, oil-based and 100% acrylic coatings on new
or weathered wood decks, siding, fences, shakes and
shingles, use a product such as BEHR PREMIUM Wood Stain
& Finish Stripper No. 64 and follow all label instructions.
Use a product such as BEHR PREMIUM All-In-One Wood
Cleaner No. 63 and follow all label instructions to clean and
brighten the wood surface and to remove light to medium
stains caused by mold, mildew, algae and fungus.
New Masonry (Stucco, Concrete, Concrete Masonry
Units (CMUs), Split-Faced Block): 30 days of concrete
cure time is not required prior to rst use. Allowing
concrete to set for 7 days before painting is recommended.
The pH must be 13.0 or lower prior to coating. Follow
manufacturer’s instructions to remove form release and
curing agents from concrete substrates. Smooth masonry
may require an adequate prole for adhesion. For all other
smooth trowel concrete, create an adequate prole for
adhesion using a product such as muriatic acid etcher or with
mechanical means. Remove all loose aggregate and debris.
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 eorescence and neutralize.
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.
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 conrm 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.
