A. WOOD - to be painted
All wood surfaces must be dry, free of grease, oil and mildew, mortar and asphalt splatters.
Rough surfaces are to be sanded smooth. Nail holes and cracks are to be puttied, door and window trim and joints are to be caulked after surfaces have been primed with Moorwhite Primer (100) or Moorcraft Super Spec Alkyd Exterior Primer (176). Caulked surfaces are to be primed with appropriate primer. Benjamin Moore has a complete selection of Moorlastic Caulking Compounds.
Painting is not to be done during or immediately following foggy, rainy or frosty weather; nor when the temperature is expected to go below 50° F before the coating has dried.
Avoid painting surfaces while they are exposed directly to the hot sun, and refrain from painting during windy or threatening weather.
Cedar and redwood siding, shakes, or shingles to be painted must be primed with Moorwhite Primer (100), Moorcraft Super Spec Alkyd Exterior Primer (176), Moorcraft Super Spec Latex Exterior Primer (169), or Moore's Latex Exterior Primer (102).
Cedar and Redwood are bleeding woods, they must be primed to help prevent and retard bleed.
Pressure Treated Wood (PTW) must be tested prior to coating to determine proper penetration of coating. Surface must be sprinkled with water to determine absorption into substrate. If water drops remain on PTW surface, do not paint. If water drops penetrate immediately into surface, prepare surface as you would any wood and then prime with Moorwhite Primer (100), Moorcraft Super Spec Alkyd Exterior Primer (176), Moorcraft Super Spec Latex Exterior Primer (169), or Moore's Latex Exterior Primer (102).
Smooth planed clapboards or siding must be sanded thoroughly to break the "mill glaze" to allow proper penetration and adhesion.
If mildew is evident, it must be removed by scrubbing with a commercial mildew wash formulated for this purpose. CAUTION: Follow manufacturer's directions; use rubber gloves, work goggles and protective clothing.
B. WOOD - to be stained
New work: Surfaces to be stained must be clean and dry. Remove dirt, oil or grease by washing with a detergent solution; flush with clean water. Incidental contaminated of asphalt and concrete spatters and construction marks must be removed.
If mildew is evident, it must be removed by scrubbing with a commercial mildew wash formulated for this purpose. CAUTION: Follow manufacturer's directions; use rubber gloves, work goggles and protective clothing.
If steel nails have been used, they should be countersunk and filled to eliminate rust leach stains.
Smooth planed clapboards or siding must be sanded thoroughly to break the "mill glaze" to allow proper penetration and adhesion.
Rough or textured surfaces are to be abraded with a stiff fibre brush to remove loose fibers and splinters.
Staining is not to be done during or immediately following foggy, rainy or frosty weather; nor when the temperature is expected to go below 50° F before the stain has dried.
Under light solid color stains and where bleeding might be a problem, use Moorwood Exterior Primer (094).
C. MASONRY - Poured/Precast Concrete, Cement/Cinderblock and Stucco Surfaces
All surfaces must be thoroughly brushed with a stiff fibre brush to remove loose particles, with particular emphasis on stucco surfaces and mortar courses.
Surfaces are to be dry, free of greasy residue, mortar and asphalt spatters.
Cracks, joints, and large voids are to be filled by repointing, caulking or other approved means. Benjamin Moore has a complete selection of Moorlastic Patching and Caulking Compounds. Note: if honeycomb in poured or precast concrete surfaces are to be filled, this should be specified.
Form release agents are to be removed with appropriate solvents, and laitance deposits must be removed by hand or power wirebrushing, or other appropriate means.
Poured concrete and precast concrete must be allowed to cure for 60 - 90 days; block and stucco surfaces must be allowed to cure for 30 - 60 days.
If efflorescence is present, first dampen the wall with water, then scrub the surface with a 10% solution of muriatic acid. Caution: Wear rubber boots and gloves, work goggles, and protective clothing. After treatment, thoroughly flush the surface with clean water to remove all acid and allow to dry thoroughly before painting.
If mildew is evident, it must be removed by scrubbing with a commercial mildew wash formulated for this purpose. CAUTION: Follow manufacturer's directions; use rubber gloves, work goggles and protective clothing.
D. MASONRY- Cement Floors
Poured concrete floors/platforms must cure for 60 - 90 days.
Floor is to be washed with Moore's IMC Oil & Grease Emulsifier (M83).
Steel troweled concrete must be etched with a 10% solution of muriatic acid or Moore's IMC Concrete Pretreatment & Etch (M85), rinsed thoroughly and washed with Moore's IMC Oil & Grease Emulsifier (M83) and then thoroughly rinsed. Allow surface to dry completely before painting. CAUTION: Always wear rubber gloves and boots, and work goggles when using muriatic acid or Moore's IMC Concrete Pretreatment & Etch (M85). Follow label directions.
Cement spatters should be removed; holes and crevices are to be filled with concrete patching compound. Surface is to be swept free of dirt and debris.
E. METAL - Structural or Plate Steel
All surfaces must be free of residual deposits of grease and oil, and shall be cleaned in accordance with SSPC-SP1-63, "Solvent Cleaning."
Surfaces that exhibit rust formation, mill scale, etc., must be cleaned in accordance with SSPC-SP2-63 "Hand Tool Cleaning," or SSPC-SP3-63 "Power Tool Cleaning." Particular care is to be exercised to remove welding flux, slag and fume deposit as is possible by blast cleaning, washing with water, phosphate rinsing or power tool cleaning. Weld spatters and burrs must be removed. Coat surface where all traces of rust cannot be removed with Moore's IMC Rust Converter (M82) or Moore's IMC Rust Pretreatment (M84).
Primer coats should be applied without delay, before rust reappears, with IronClad Alkyd Low Lustre Metal & Wood Enamel (163), Ironclad Latex Low Lustre Metal & Wood Enamel (363), Moore's IMC Acrylic Metal Primer (M04), Moore's IMC Alkyd Metal Primer (M06), or Moore's IMC Universal Metal Primer (M07).
F. METAL - Galvanized
All new surfaces must be free of grease, oil, dirt and contaminants and shall be cleaned in accordance with SSPC-SP1, "Solvent Cleaning." "Solvent Cleaning" can be accomplished by using Mineral Spirits or Moore's IMC Oil and Grease Emulsifier (M83). Be sure to change to clean rags or wiping cloths regularly as to reduce possibility of recontamination of the surface. Galvanized metal buildings may be cleaned using high pressure spray method, with a commercial wash.
Peeling and scaling paint and chalk must be removed by scraping, sanding and wirebrushing. Rusted and abraded surfaces must be cleaned by scraping, sanding and wirebrushing, then primed, without delay, with one of Ironclad Latex Low Lustre Metal & Wood Enamel (363), Moore's IMC Acrylic Metal Primer (M04), or Moore's IMC Rust Converter (M82).
Weathered, unpainted galvanized metal surfaces must be wirebrushed or power washed to remove deposits of "white rust," then primed with Ironclad Latex Low Lustre Metal & Wood Enamel (363) or Moore's IMC Acrylic Metal Primer (M04).
Note: Some galvanized surfaces have stabilizers. Many of which are not soluble in solvents. These must be removed by either brush blasting or chemical treatment.
G. METAL - Aluminum (framing, structure)
Surfaces specified for painting require no special preparation other than solvent cleaning. All mortar spatters and other foreign material must be removed by appropriate means.
H. WATER RESISTANT SOFFIT BOARD, CEILING BOARD
All surfaces must be free of sanding dust, and joint treatment cement should be thoroughly dry. Damaged or defective surfaces are to be repaired by spackling or by other appropriate measures. Benjamin Moore has a complete selection of Moorlastic Spackling and Caulking Compounds.
Apply one coat of Moorwhite Primer (100) or Moorcraft Super Spec Alkyd Exterior Primer (176).
