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: For exterior 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.
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. Be sure to follow
all label instructions.
WARNING! Sanding or scraping pressure treated lumber
may be hazardous; wear appropriate protection.
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.
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.
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.
Glossy Surfaces: For maximum adhesion, sand the surface
thoroughly to provide a rough surface before coating.
