Product Specification
Modern Masters® Metal Effects® Oxidizing Copper Paint is a water-base, modified acrylic paint with a high concentration of real copper particles. It will tarnish naturally over time, if exposed to the proper elements, but Metal Effects Green
Patina Aging Solution will speed up the oxidation process to create a beautiful authentic green patina finish in minutes. The entire system can be applied to any properly prepared surface, including metal, wood, drywall, plaster, paintable
wall coverings, canvas or muslin, and plastic surfaces.
Popular applications range from full interior and exterior walls, moldings, trim, columns, doors, railings, to lamps, vases, and planters.
ALL SURFACES: Remove dirt, grease, oil, salt and chemical contaminants by washing the surface with a commercial detergent or other suitable cleaner. Rinse
thoroughly with fresh water and allow to fully dry. If any mold or mildew is present on the surface clean further with one quart of household bleach added to a gallon of water. Rinse with clean water. Severely mildewed areas should be cleaned with a chlorinated cleansing powder and thoroughly rinsed with water. All surfaces must be dry at time of application.
PREVIOUSLY COATED: Previously coated surfaces must be sound and in good condition. Smooth, hard or glossy finishes should be scarified by sanding to create a surface profile.
Modern Masters Metal Effects paints can be brushed, rolled, or spray applied (See specific equipment requirements under Spraying) onto any paintable, properly primed, interior or exterior surface, such as walls, ceilings, columns, trim, doors, furniture, and paintable wallcoverings. Always test the product in a small, inconspicuous area before beginning a project to see if the desired results are attained. We recommend preparing a sample board prior to beginning a project to check color and technique. The paint should be mixed thoroughly before using.
Do not apply in temperatures below 55°F/13°C or above 85°F/29°C.
BRUSHING: Use a high-quality brush recommended for water base semi-gloss paints.
ROLLING: To roll Metal Effects Copper Paint use a high-end ½” nap roller and/or a natural sea sponge roller for added effect.
SPRAY: The Metal Effects Copper Paint can be spray applied using conventional air atomized spray or HVLP. Thin with clean, fresh water up to 12.5% by volume, one pint (16 fl. oz.) per gallon. Do not over thin as this can result hide and appearance. The actual amount of thinning will depend on the type of spray equipment being used. Be sure the air supply is clean and oil free.
Taping: Use high quality, low-tack tape when taping over surfaces that have been previously painted with Metallic Paint. When painting over taped-off areas be aware that Metallic Paints exhibit poor early adhesion properties and are elastomeric (they stretch) before curing. Consider cutting along the tape edge with a razor blade to avoid delaminating the fresh paint from the substrate.
STEP 1: Apply at least two coats of Metal Effects Primer to completely seal and block the surface. Some metal surfaces, such as bare aluminum, galvanized metal, or rusted or slag metals, will need a specialty primer from our recommended primer list, applied prior to the application of Metal Effects Primer. If this is the case, read the specific information for the recommended primer prior to beginning your project.
STEP 2: Apply first coat of Metal Effects Oxidizing Copper Paint and allow to dry. Apply a second coat of Metal Effects Oxidizing Copper Paint in the same manner. The Green Patina Aging Solution should be applied while this coat is still wet (within 5 minutes).
STEP 3: Apply the Green Patina Aging Solution with a brush, sea sponge or spray apply with a plastic pump sprayer. As the activated surface dries (approx. 30-40 min.) a real patina finish will appear. Cold temperature and/or humid conditions will prolong the oxidation process and dry time.
STEP 4: (Optional) Protective Clear Coating – Patina finishes do not require a clear protective finish, except if the patina surface is subject to repeated hand contact, such as hand rails. If a protective sealer/topcoat is desired, use Metal Effects Permacoat Xtreme. DO NOT USE OTHER SEALERS OR VARNISHES. Permacoat Xtreme can be applied by brush, roller or spray. Surface must be completely dry prior to top coating (minimum of 24 hours). First coat: Add equal parts of Permacoat Xtreme with water and stir well before applying. Second coat: Apply Permacoat Xtreme at full strength. Let surface dry for 1 hour before handling. Full cure time is 7 to 10 days.
Recoat time is approximately 30 minutes. Dryto-touch time is approximately 1 hour. (Drying times were recorded at 70°F and 50%RH.)
Note: Lower temperature and/or higher humidity will lengthen the dry and cure times.
Clean brushes, rollers, tool, and equipment with soap and warm water immediately after use. Promptly wipe up spills and splatters with a damp cloth.
