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 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 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. Prime the area 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 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.
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 topcoating the entire area. If bleeding
continues, primer may need a longer dry time before
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.
