GENERAL SURFACE PREPARATION
APPLICATION INFORMATION
Surface must be clean and dry. Remove all loose, peeling paint, dirt, mildew, grease, oil, chalk, rust, and any other surface contaminants.
Repair all moisture problems. Blistering and peeling issues are commonly caused by moisture behind the paint film. Putty all nail holes and
caulk all cracks and open seams. Sand all glossy, rough and patched surfaces. When Paramount Paint + Primer in One exterior paint is
applied to an uncoated substrate or to bare wood, two coats are required with the first coat acting as the primer. For metal, tannin staining
woods, fresh concrete or masonry (less than 30 days cure), or chalky surfaces, use of the appropriate high quality specialty primer is
recommended for best results.
WARNING! If you scrape, sand, or remove old paint, you may release lead dust or fumes. LEAD IS TOXIC. EXPOSURE TO LEAD DUST
OR FUMES CAN CAUSE SERIOUS ILLNESS, SUCH AS BRAIN DAMAGE, ESPECIALLY IN CHILDREN. PREGNANT WOMEN SHOULD
ALSO AVOID EXPOSURE. Wear a properly fitted NIOSH-approved respirator and prevent skin contact to control lead exposure. Clean
up carefully with a HEPA vacuum and a wet mop. Before you start, find out how to protect yourself and your family by contacting the
USEPA National Lead Information Hotline at 1-800-424-LEAD or log on to www.epa.gov/lead. In Canada contact a regional Health Canada
office. Follow these instructions to control exposure to other hazardous substances that may be released during surface preparation.
ALUMINUM: This substrate may present potential adhesion problems. Any coating applied directly to aluminum should be spot applied,
allowed to cure overnight, and then evaluated for adhesion. If adhesion is good, the application may proceed.
BRICK: New brick and mortar should cure for at least 7 days and preferably 30 days prior to priming and painting. The pH of the
substrate must be less than 13 before priming. Painting glazed brick is not recommended due to potential adhesion problems.
CONCRETE and MASONRY: New concrete should cure for at least 7 days and preferably 30 days prior to priming and painting. The pH
of the substrate must be less than 13 before priming.
FERROUS METAL: The surface must be cleaned thoroughly to remove any dust, rust, and surface contaminants, and then primed.
FIBER CEMENT: Fiber cement siding and trim board may present potential adhesion, alkali burn, and efflorescence problems. New board
should be aged for at least 30 days prior to priming and painting. The pH of the substrate must be less than 13 and the moisture content
must be less than 12% prior to priming and topcoating. All cracks and opens seams should be caulked to prevent water penetration.
Pre-primed board from the manufacturer may not be uniformly or completely sealed. It is recommended that an alkali resistant primer be
applied to ensure complete and uniform sealing prior to topcoating.
STUCCO: New stucco should cure for at least 7 days and preferably 30 days prior to priming and painting. The pH of the substrate must
be less than 13 before priming. Surface chalk from the curing or aging process should be removed then sealed with an appropriate sealer
to rebind and restore the surface to a sound condition.
VINYL and ARCHITECTURAL PLASTIC: Vinyl and similar architectural plastics may present potential adhesion problems. A primer may
be required to promote proper adhesion. Consult the manufacturer’s guidelines prior to painting. Primer and topcoat should be spot
applied, allowed to cure overnight, then evaluated for adhesion. If adhesion is good, the application may proceed. Check adhesion by
applying a piece of masking tape. When the masking tape is removed, if the coating peels off, the surface must be scuff sanded prior to
proceeding to ensure mechanical adhesion.
WOOD: Unpainted wood or wood in poor condition should be sanded smooth, wiped clean, then primed. Any knots or resinous areas
must be primed before painting. Countersink all nails, putty flush with surface, then prime.
Stir thoroughly before using and occasionally when in use. When using more than one container of the same color, intermix to ensure
color uniformity.
Application Equipment: Apply with a high quality brush, roller, paint pad, or by spray equipment. Where necessary, apply a second coat.
Airless Spray: Minimum requirements: 1 gal./min. flow rate; pressure 1800-2400 psi; tip 0.015” - 0.021”.
Spray equipment must be handled with due care and in accordance with manufacturer’s recommendation. High-pressure injection of coat-
ings into the skin by airless equipment may cause serious injury.
Brush: Polyester/Nylon Brush
Roller: 3/8” - 3/4” nap roller cover.
Thinning: Do not thin with water or other additives.
Permissible temperatures during application:
Material: 50 to 90ºF 10 to 32ºC
Ambient: 35 to 100ºF 2 to 38ºC
Substrate: 35 to 100º 2 to 38ºC
